Video Transcript for In-Depth Review of the Replacement Key Wall Control For MaxxFan Plus and Deluxe
Today, we're going to take a quick look at the Replacement Key Wall Control for MaxxFan Plus and Deluxe. This is going to be a 4-key wall control for your MaxxAir fan. It's going to give you your Fan Off, On, your Vent Open, and Close controls so you can easily control your vent and fan from across the room. You don't have to get up and operate it every time. We'll also have little covers for our hardware here. We get two screws to get this mounted onto the wall.
On the back of that mount, you'll see our connection to power there. It's just going to be that little plugin, and then these two holes are going to be our mounting holes. So, whenever you have your screws in place, you'll actually have the little black portion behind it. The little connector in between is just for shipping, but, basically, that just connects into that little opening at the top so it provides a secure hold on your wall mount there.Again, we'll have all four of those controls so we can easily operate our MaxxAir fan from wherever we are. This is going to work for the MaxxFan Plus, Part numbers 4751KS or 4951KS, and the MaxxFan Deluxe, which is going to be 8751K or 8951K.
This is going to be about 3-1/8" long, about 2-3/8" wide, and about 1-1/8" deep.That's going to do it for our look at the Replacement Key Wall Control for MaxxFan Plus and Deluxe.

Received item within a few days of ordering. Took 5 minutes to install; excellent replacement for the original controller that still worked but the plastic was coming off of it exposing the actual switch inside the controller.

Prices are competitive, products are as described, shipping is timely, and tracking is accurate. etrailer kept me advised on the status of my order every step of the way.
The wall control is a major improvement over the older model, it was easy to install. Depending on your trailer the existing hole may have been created by a hammer or gnawed into the wall by the manufacturer. In that case you might have to build some kind of bracing. Otherwise, it is a 10 minute job.

Easiest fix ever! One button on our old one became unreliable. I ordered the new part and had it in a matter of days. I just popped the old face off unplugged it, plugged the new face in and snapped it back in place. Works perfectly!

Exact replacement. Factory screwed my original through the back half plate into the wall so I just popped the fronts off and swapped them out. All the buttons and internal board are all screwed to the front half of the control box making swapping the fronts is super easy if you have the same situation.

No wiring instructions provided with the switch box. Nothing about what kind of plug in cable is needed. Going to have to take more time and research on line. I am doing a changeout from a different brand not a replacement of the same unit.

Typically, with replacement parts like these the manufacturer does not always include the manual. I have a link that I am sending that is a copy of the manual from the manufacturer's website. The wiring starts on page 4 of the manual.

While not a direct replacement for the switch that failed (probably an updated part) it plugged in and controls our bathroom fan properly.

It must be wired wrong. I push the vent open and nothing, I push vent close and it opens and turns on the fan. I push fan on and it closes the vent, but fan stays on. I push the fan off and it closes the vent and turns off the fan. Not sure what is going on. Not pleased.
Jenny N.

It does sound like something strange is going on. I would like to reach out to the manufacturer however I know that they will want to know what model of fan that you have is . Can you let me know?
Greg

sorry for the delay in response. here is the model and serial number: Model: 4951KSC Serial: 2110-4951KSC-0994

I heard back from the manufacturer much quicker than I expected. To them it sounds like the wall control is faulty. They suggested to make sure that the RJ-11 cable is plugged in all the way in the wall control and to clean the terminals on the wall control.

- Correct Replacement Wall Switch for MaxxAir Vent FanI wasn't able to reference this part number but we do carry a few wall mount switches for MaxxAir Vent Fans, the part # MA59FR and part # MA00A03550K. If yours look like either of these two options then they will work great for you but they are the only options we offer at this time. If you can provide me with the model number of the actual unit I may have a better answer for you but again, if your controller looks like either of the above then chances are it will work great with your unit.
view full answer... - MaxxFan Model 4751KS Will Not Shut OffI took a look at your order and saw you had purchased the Replacement Key Wall Control part # MA00A03550K but the issue you are having with your MaxxFan Model 4751KS is the circuit board, the Replacement Circuit Board part # MA10A04751KS so this what you need to replace.
view full answer... - Why Won't My MaxxAir MaxxFan Shut Off? Wall Control and Circuit Board TroubleshootingHey Alan, Yes, either the wall control or circuit board could be causing your MaxxAir fan to run continuously. I see you just ordered the Replacement Wall Control # MA00A03550K, so hopefully that solves it! In the meantime, here are a few things I'd check: Reset the fan: Turn off its 12V power at the fuse or breaker for about a minute, then restore power and see if the controls respond normally. Check the control cable: Remove the wall control and make sure the RJ-11 connector is fully...

The remaining items you'll need is the Key Wall Control part # MA00A03550K, Ceiling Garnish part # MA54FR, RJ11 Communication Cable part # 34279523, and the Roof Vent Installation Kit part # 344270KITW. Included is a picture of where you'll find the RJ-11 and RJ-45 connection points on the MaxxFan Plus 4-Speed Roof Vent...

- Will Replacement MaxxFan Plus 4-Speed Roof Vent Work With Wall SwitchHi Steve; does your wall switch look like the # MA00A03550K? The Replacement MaxxFan Plus 4-Speed Roof Vent # MA00-04751KSX is designed to replace the 00-04751KS which works with this wired wall controller. If you have this switch, or the older model with the fan off/on and vent open/close functions, the replacement vent is compatible.
view full answer... - Replacement For 4-Key Wall Control For MaxxFan Plus/DeluxeHi Jacob, The # MA59FR won't work as a replacement for your MaxxFan Plus or Deluxe which uses the 4-button control. We do have the right replacement for you though, which is the following: - Replacement Key Wall Control For MaxxFan Plus and Deluxe - 4 Key # MA00A03550K This is for the MaxxFan Plus (4751KS or 4951KS) and MaxXFan Deluxe (8751K or 8951K) models.
view full answer... - Parts Needed To Install MaxxAir MaxxFan Plus Roof Vent As New InstallThe MaxxAir MaxxFan Plus Roof Vent part # MA00-04751KSX is designed to replace an existing roof vent fan. Therefore, it does not come with everything needed for installation. The extra items you will need are as follows: Key Wall Control part # MA00A03550K Ceiling Garnish part # MA54FR RJ11 Communication Cable part # 34279523 Roof Vent Installation Kit part # 344270KITW
view full answer... - Is MaxxFan Plus 4-Speed Roof Vent Compatible With Wall ControlHey Jay! The MaxxFan Plus 4-Speed Roof Vent # MA00-04751KSX does not come with a wall controller but it is compatible with one. You will have to pick up the Replacement Key Wall Control For MaxxFan Plus and Deluxe # MA00A03550K separately.
view full answer... - Troubleshooting MaxxAir 4751KS Vent Lid Not Opening And Fan Running All The Time.Based on the issue you are having, Yes. A bad circuit board can cause all kinds of weird issues like your fan running all the time and the vent lid not opening. Since you have the MaxxAir 4751KS you will need the replacement circuit board # MA10A04751KS. I included a video of the # MA10A04751KS for you to take a look at.
view full answer... - Replacement Circuit Board and Rain Sensor for MaxxFan Plus The MaxxFan Plus Roof Vent w/ 12V Fan, Thermostat, and Remote - Powered Lift - 10 Speed - Smoke # MA00-04500K is the similar fan to the 4951ksc. The issue you are having with the fan and lid are likely the circuit board which can be replaced with # MA10A21275K. However, the issue could be as simple as replacing the rain sensor. The Replacement Rain Sensor for MaxxAir RV or Trailer Roof Vent Fans # MA34FR is what you need for that and the rain sensor going bad causes the lid to close...

- Remote Control Compatible With MaxxAir MaxxFan 4500KYour MaxxFan Plus Roof Vent # MA00-04500K uses the Remote # MA00A01150K. The Key Wall Control # MA00A03550K is not compatible with your fan.
view full answer... - Solution for MaxxFan 4751KS That Won't Open Manually or With Wall SwitchIt sounds like the operator of your MaxxFan is locked up or damaged since it won't open manually or with the motor. For a replacement you'd need the part # MA10-20281K-1AF and you'd be set.
view full answer... - Can I Use a Wireless Remote for the MaxxFan Plus part # MA00-04751KSX?Hi James, I'm really sorry to tell you, but the MaxxFan Plus part # MA00-04751KSX will not work with a wireless remote. The MaxxFan Plus part # MA00-04751KSX is a direct replacement for the MaxxFan Plus original model 00-04751KS and is intended to work with the existing wall mounted controller part # MA00A03550K. To get a roof vent that has a wireless remote you need the MaxxFan Plus part # MA00-04500K. I know you've just replaced your old unit so it's totally understandable not wanting...
view full answer... - Can A Powered Lift Vent Function On An RV Roof Vent Be Wired To A Switch For ActivationThe switch on your wall is only turning the power on and off for the fan. With a powered lift there wouldn't really be a way to tap into the function and wire it to a switch to make it easier to access. The only option would be to replace the current vent with one that has a remote to activate the lift function, like the MaxxFan Deluxe Roof Vent w/ 12V Fan # MA00-07500K. There are also certain models (MaxxFan Plus: 4751KS or 4951KS and MaxxFan Deluxe 8751K or 8951K that can use wall mounted...

The # MA59FR controls the 10-speed fan, electric lift lid, thermostat, and both the intake and exhaust fan functions on aftermarket and OEM models 00-04500K, 00-04700K, 00-04800K, 00-04900K, 00-07000K, 00-07500K, 00-08500K, 00-08700K, and 00-08900K.

What you can use is the Communication Cable # 34279523. I have added links below to video reviews for you to check out as well if you'd like to take a look.
view full answer... - Will 14" x 14" Roof Vent Fit a 2015 Lance 1052 Camper with 14-1/4" x 14-1/4" Roof OpeningYou will definitely be able to install the MaxxAir MaxxFan Plus Roof Vent w/ 12V Fan # MA00-04751KSX on your 2015 Lance 1052 truck camper just fine. Basically anybody that measures 14" or 14-1/4" for a vent has the same vent dimensions. People will measure either the opening on the inside or outside, the lid, or even just the opening in their roof which is where the slight differences come into play. If you measured 14-1/4" then the MaxxAir vents will fit like a glove. Please note that...
