Excellent replacement for our 2013 Keystone Raptor 300MP. Installation was a breeze-almost “plug and play” as fit in pre-existing area was perfect.


Had a power surge while traveling in Arizona last year. It took out the Dometic microwave. Could not find a replacement Dometic that would fit in the cabinet so went without for some time. Researched many different microwaves from different RV accessory businesses and could not find anything that would not require modificaiton of the cabinet. Finally went on and found much more information regarding dimensions of unit and dimensions of the trim kit. Read many reviews and determined the Greystone unit would work for us. Placed the order, it arrived in less than a week, installed it with absolutely no difficulty and I am now a happy camper. It is a little smaller than the original but for what I use it for, the size change will not matter. I liked the price as well. Most microwaves today are combined with convection ovens and I do not find the convection ovens worth the money.This Greystone is just a simple microwave for defrosting frozen goods, warming leftovers, heating up cereals and vegetables which is what I use the microwave for primarily. Will use etrailer whenever we can.

The Greystone microwave is working out perfectly. Lived in the RV for 3 months this past winter and used the microwave nearly everyday. Excellent product.


Perfect exact microwave!! Madison H fixed me up with the microwave that I needed...rather than the wrong microwave that I ordered!!! Great job Madison!!! You're wonderful!!! Under 15 minutes pulling out the old microwave and installing the new one!!! Thanks again everyone!!


Excellent comparable microwave to replace original Sylvania in our Keystone Springdale 256. Price point was at the upper limit of what our budget would allow.


I was searching for a microwave that would replace an older model in an older motor home . Searched the big A site without much success and happen to stumble across “ etrailer “ .. woo hoo am I happy . Better price and near perfect fit . Easy to order and quick delivery. My new go to RV center. Thank you!!


Really happy with etrailer ! Placing the order and shipping was fast and efficient.


Replaced our failed Samsung with the Greystone. Fit nicely in the old space with minimal modifications. Has been performing fine. Shipment was packed well and arrived in a timely fashion.


Perfect fit and function best price very happy



Excellent buy no issue ar all


PERFECT FIT! I love the new rv microwave. I love the look of it. It looks as if it has a mirror for the door. And being it would replace an old rv microwave, it only had a certain amount of space to fit in. It fit perfectly. It looks like it was made for our camper. I bought it with the trim kit and it was a breeze to install. It took no more than 3 minutes to install both microwave and kit. The best customer service I have ever had, as well. I had a very small concern and emailed the company last night and within 2 minutes, they had emailed back with an answer. Thank you etrailers. I am a return buyer.


PERFECT 1-for-1 replacement to our old "Magic Chef" 0.9 cu ft Forest River Rockwood Too Microwave. Great price and OMG..... did you strap the delivery to Superman and tell him to head on over or WHAT?!?!??!! LIGHTNING FAST delivery!!

Actually, he has been looking for a more low profile gig, so he works part time in deliveries. Cool guy!


Bought this to replace an old non-working Sylvania unit in our horse trailer. The microwave came quickly and fit perfectly. It’s got a very nice modern look to it and seems to function as it should. Was a breeze to install



Still working great after a year! Looks good in our trailer. No complaints


Excellent Price. Greystone Microwave with trim kit fits perfectly in motor home where old microwave was. Very very satisfied.

Howard M.


Juut fine. Our friend purchase 2021 Trailer and the exact same microwave was in her Trailer. Works the same.


This recomendation was the perfect replacement for the unit that was in my sprinter. Slightly smaller but fits in the area. Nothing fancy but does the job


Perfect fit and modern look.
was a snap with a screw gun.


We purchased this as a replacement for our Airstream Excella. As always, etrailer is wonderful to work with. Shipping was fast and the etrailer team is top-notch. After the first microwave arrived damaged due to a packing issue at the factory, etrailer sent another microwave and covered the return shipping of the damaged unit. The second arrived with different packaging of the turntable. I was able to install it in minutes. It fit perfectly and works like the original.


The microwave works as expected both on household current and on the 2000 watt inverter in my trailer. It was easy to install and it looks very nice in the trailer. Operating instructions were clear.


We had to replace our original equipment Dometic Microwave as it quit heating. I looked around on the Internet to replace it and as always ended up shopping at etrailer. I called and spoke with Derek S and we came to the conclusion that the Greystone microwave would fit.

I ordered it and it arrived on time and in good condition. It took us 20 minutes to install which included opening the boxes and getting the tools. Four screws to attach the trim, plug it in slide into the opening, pre drill four holes for the trim and screw it down.

Again our experience with etrailer and the products we have bought from them have been outstanding.


I have spent weeks searching for a microwave oven replacement for our motorhome. Trying to find the right size to fit in an existing cabinet with an available trim kit was frustrating. Then there it was at with all 5-star reviews. Received it fast and got it installed with minimal effort (had to flip the trim kit). This microwave looks great and works even better. The only thing I was never able to find out from my research was if it had an interior light. It does.

Thanks etrailer!


The unit came as advertised. The trim kit was simple to install. It was not a perfect fit for my 2007 Outlaw but I was able to make it work easy enough. Microwave looks good and works great.


Unbelievable, microwave fit like a glove no problems with it so far I’m very satisfied with my purchase. Thanks etrailer



Perfect no problem at all very satisfied

@Robert Glad to hear that your Greystone # 324-000105 RV microwave is working well for you.


The product was ok when I received it but the shipper box was torn up and the bottom of the box was cut open and the product was exposed I’m gonna try this oven and go from there I hope ev is ok


Awesome replacement for the old Apollo microwave! The fit was excellent and no modification needed! The trim was the perfect size!



The new microwave is working out perfect! Easy operation and easy install!


Our customer service rep, Odelia, was knowledgeable about the microwave and processed our order in a very timely manner! We received our order the day it was promised to us when we ordered it! Great service!


eTrailer has excellent, responsive customer service! My boxes got split up by the shipping company and arrived a day apart. I thought there was a problem, but they reassured me that my 2nd package was on the way. The first package arrived a day earlier than expected, so in all everything arrived as predicted. The install was easy!! And it actually fits better than the one that died on me. Very pleased with the overall experience and would definitely buy from etrailer again!!!


Great service. Exactly what we ordered and needed for our camper. Looking forward to installing it when we get back from vacation and will send an update then.

  • Can Buzzer Sound Be Muted on Greystone Standard RV Microwave 324-000105
    I checked the owner's manuals for all of our microwaves and unfortunately, there are none that have the ability to mute the buzzer including the Greystone Standard RV Microwave part # 324-000105. In order to stop the buzzer from sounding you'll need to manually cancel the timer before it elapses.

  • Replacement Options for a Dometic 56-2281-10/03 RV Microwave
    I do have some options for you to replace the Dometic 56-2281-10/03 but I was not able to find any specs for this. That said, if you simply measure the unit and compare this to the sizes we offer below via the link, you should be able to get a pretty close match to your original microwave. The Greystone Standard RV Microwave part # 324-000105 for example could be a suitable replacement measuring 19" wide x 13-1/2" tall x 14-1/4" deep without the trim kit and 23-3/8" wide x 15" tall with...

  • SR-11092B microwave 2007 Winnebago Vista.
    The dimensions of your Sylvania Microwave SR-11092B are 12-1/4" tall x 20" wide x 13" deep. Compared to the Greystone Microwave part # 324-000105 (12" tall x 19" wide x 14-5/8" deep), this microwave will fit as long as you have the extra 1-5/8" of extra space behind your old microwave in your Winnebago for the new one to slide back. You would need to use the new bezel, not your old one. I have included a link to a video review for the new microwave.

  • Determining The Correct Replacement Microwave For A 1997 Tioga Montara Class C Motorhome
    Since we don't carry Samsung products I don't have any way to determine the part number but I can recommend a microwave based on the size of the cutout hole you have. For example, the Greystone Standard RV Microwave # 324-000105 is 19" wide x 13-1/2" tall x 14-1/4" deep. If you can provide the space you have available I can find the correct fit for your application.

  • Replacement for my Sylvania SR-11092B Microwave in Eagle Cap Truck Camper
    The recommended amount of depth needed to install the Greystone microwave part # 324-000105 that you referenced is 16 inches so you're about an inch too shallow for this to fit unless you wanted to come up with a spacer to install between the mounting flange of this and your current cabinet so that the depth figure would be enough. The Sylvania SR-11092B you have now is unusually shallow at 13 inches which is why we don't have any other options that would fit like it did for you.

  • Recommended Replacement For A Samsung MR1032UBC RV Microwave
    The closest RV microwave we carry to match the dimensions of your Samsung MR1032UBC microwave is the Greystone Standard RV Microwave w/ Trim Kit # 324-000105. The trim kit will cover the width of your your opening but will not completely cover the 17" height. What you can do to solve that is to cut down a piece of wood to 3" by the length of your cutout hole and stain it to match your cabinets. You can use a pocket hole jig from your local hardware store and a few screws to mount the board...

  • Replacing a Greystone Microwave Oven P90D23AP - X3 - FR03 From Its Cabinet Enclosure
    Your Greystone Standard RV Microwave w/ Trim Kit # 324-000105 is going to be likely only held in place by the front trim panel and the 4 screws that attach it to the front of the cabinet. Depending on your cabinet opening and the manufacturer of the RV once you have removed these screws you will either be able to just slide out the microwave from its shelf or you may have to lift the unit off its base if they included risers in the cabinet to get the microwave to the desired height.

  • Determining if Greystone Microwave 324-000105 Can Replace Samsung Model in Keystone Montana
    The Greystone Built-in Microwave # 324-000105 that you referenced may be a great replacement for your existing Samsung MR5481G model, but your best route to ensure a good fit will be to compare its dimensions to those on this Greystone unit. Unfortunately trailer manufacturers don't typically make information like this available and I wasn't able to track down any specific specs on the Samsung MR5481G, so I'm not able to verify compatibility.

  • Sylvania SR-11092B Troubleshooting Issues
    From what you're describing about your Sylvania microwave the drive transistors or the control board is bad. Since we don't carry that brand you'll have to contact the manufacturer for replacement parts or you can replace the unit with one from our selection. I've attached a link to our microwave page for your convenience.

  • Can Greystone Built-In Microwave # 324-000105 Be Used in Apartment
    There is no particular reason why you couldn't install the Greystone Built-In Microwave # 324-000105 in your apartment instead of an RV/trailer. It runs on standard household 120V so it would work just fine. It requires a cutout of just over 12 inches tall and 19 inches wide. I have attached a short video demonstration that you can also check out.

  • Replacement Microwave for High Pointe EM925BSC in a 2008 Dutchmen Victory Lane
    The best replacement microwave we have for your 2008 Dutchmen Victory Lane with the High Pointe EM925BSC is the Greystone Built-in Microwave with Trim Kit part # 324-000105.

  • How to Tell if Greystone Standard RV Microwave w/ Trim Kit Will Fit in RV
    The Greystone Standard RV Microwave w/ Trim Kit # 324-000105 has overall dimensions of 23-3/8" wide x 15" tall x 14-1/4" deep but that's with the trim kit. Without the trim kit the microwave measures 19" wide x 13-1/2" tall x 14-1/4" deep so the unit itself will fit in the space you're talking about width-wise. If you want to use the trim then you'll either need to modify it or modify the opening for the microwave. Attached is a review video for you to check out.

  • Replacement Microwave Recommendation for Advent P90D23AL-G1-FR04 MW912B
    According to my research the Greystone Standard RV Microwave # 324-000105 is about the same size as your Advent microwave, but this microwave is designed to sit on a surface and doesn't have attachments for mounting brackets (see attached). I'm not sure of the design for your brackets so this style may still work out, but you'll want to compare what you have with the photo to determine fitment. The overall width (without the trim kit) is 19" so that base is going to be about 17" wide at...

  • Best Replacement Microwave for Advent Model MW912B in a 2014 Coachman Freedom Express
    Yes, the 0.9 Cu Ft Greystone Standard RV Microwave - 900 Watts # 324-000105 is a great replacement for your Advent model MW912B as the only real differences is the Greystone being 1/8" taller without the trim, and being about 1" less deep. With the trim they have the height will be the same dimension but you'll still have that slightly smaller depth so you're still good to go!

The exact overall measurements are 23-3/8" wide x 15" tall x 14-5/8" deep if you use the trim kit. Without the trim kit the measurements are 19" wide x 12" tall x 14-5/8" deep

For a range hood we only have one option in this color with the part # FHO23SACRSS which measures 23-5/8" wide x 4-3/4" tall x 16-11/16" deep but I am not sure this is deep enough to match what you have.

  • What To Do If The Door Release Button On Your RV Microwave No Longer Opens The Door
    Yes, if the door release button on your Greystone Standard RV Microwave # 324-000105 has zero tension and isn't opening the door then it is defective. To fix this you would have to take the microwave completely apart, which is not recommended, so replacement is the only option. If you have a different model than the # 324-000105 let me know and I can find the correct replacement for you. If you bought your camper from a dealership and have a warranty I highly recommend making a claim.
