Today we're taking a look at the replacement printed circuit board. Now, this replaces the printed circuit board for your max fan RV roof vent, with manual lift. It works with part numbers MA00-04000K, MA00-05100K and MA00-6200K.It's a direct replacement from the original manufacturer. It has the quick connect plug on these two wires over here. This is like your antennae, so that does not actually get connected, and then these two wires will need to be hard wired in and they are labeled. This one's your positive wire, white one is your negative or ground.That's going to do it for today's look at the replacement printed circuit board..

I needed a new circuit board for my exhaust fan for my van. I received exactly what I asked for in the time it said I would receive it. Which was very helpful because I needed it before I went on our trip. Thank you 695196

Thankfully these PCB board were available! Price per unit, ehh, reasonable but off set by the ease of using the etrailer site. Yes, I'd order again (if necessary). PRO's: [My story: (*No blame intended or implied; just background info.) Since I choose to order discounted/used (but top quality) vent fans. (BTW, brand new my opinion is that these fans are *excessively priced for what they really are.} Anyhow, both units arrived quickly & were very well packaged. Also, both vent fan units were in overall really good appearance/ condition but both failed to function. Troubleshooting them revealed that each of their PCB's were bad. (Although different models; thankfully both vent fans were from the same OEM mfg, and therefore, the PCB boards were the same.) Take your time but disassembly of the vent fan units was easy. Installation of the vent fan unit PCB boards was easy. After a full function test was completed on both units - they worked as mfg.d; installation of the vent fans into the RV proceeded as originally planned. FYI: Yes, I'd order from etrailer again! I'd also order again - discounted/ previously used items again knowing the ease of basic repair & parts replacement. (*Item specific.) Also BTW, even though I had to also order replacement PCB boards for these discounted/used vent fans - my final out of pocket cost was still nearly $100/dollars less than the cost of New In The Box vent fans.} CON's: (a) (My story. Sorry, a bit of a rabbit trail but related.) 1st, sorry whaaa? Did I miss it? Buyer beware! I do not recall reading anywhere on the listing for the discounted/ used vent fans that stated that the used vent fans were also "non-functioning". *Since each vent fans was still pricey (over $150.00-200.00/each). If the listing had stated that they were non-functioning & used - at the prices listed - I would not have immediately ordered them. (*Although I can't dictate to any company what "used, non-functioning' items should be listed for; in my humble opinion, non-functioning/ used vent fans, no matter the mfg, should be way less than $100.00 each regardless of condition.) Having whined about that...yes, in my case as an electronics repair tech; most likely I would have reluctantly order these vent fans. (b) *I wish that either the OEM mfg or eTrailer would there have an additional service: PCB exchange / credit for returning used PCB boards. {Even being an electronics-technician (& most people are not) - as an RV owner/ user - I'm not looking to make the task of replacing vent fans take any longer than it already will to do it right. (Additional thoughts on this point: Having a PCB exchange program would give both the distribution company & OEM mfg an additional service (less pricey) to offer their customers. As well as, as an RV owner/ user; it would be nice & convenient, quick fix on the road, to have at least 1-spare PCB assembly on hand. *Other than having to find a suitable location to store items in my RV. 691361

This isn't the easiest product to source and I was surprised that etrailer stocked it. I got an email stating a future delivery date of over a month. A quick email garnered an automated reply and the followup request for clarification gained no honor, which had me completely convinced that I had stepped into a bait and switch, possibly even a scam site (could it have been a mirror of the real site??). I realized I was at a complete loss, the internet being what it is, when......low and behold, my order arrived. Exactly as promised, in good condition. I will hold the last star only for the customer service. Nicholas-bot , when I ask, you answer. I wouldn't hesitate to order again. 643330

    The circuit board of your MaxxFan might need to be reset. If you can cut power to the fan by pulling a fuse I'd try that first. If that does not work then there would be an issue with the circuit board and you'd want to replace it with the # MA10A21276K since you have the # MA00-05100K.

  • Troubleshooting MaxxFan Deluxe Roof Vent w/ 12V Fan That Won't Turn Off
    Thank you for the question! Would you be able to expand on your situation a little more so I can better help you? Just wondering if it isn't turning off when you press the power button or does it have to do with the thermostat (provided that your MaxxAir fan has one)? Also, which MaxxAir fan do you have installed? If you can get me that info it will really help me to pin-point what needs to be looked at.

  • Troubleshooting Remote Not Working with MaxxFan Plus Roof Vent # MA00-04000K
    If your MaxxFan Plus Roof Vent # MA00-04000K isn't responding at all to the remote then most likely it just needs to be replaced with part # MA00A01150K or the batteries are just in need of a change. I do also recommend verifying that you're able to adjust the speed settings and other controls by using the buttons on the vent itself to rule out the vent from being the issue. If you can't adjust anything using the vent buttons either then the remote is likely fine but a replacement...

  • Troubleshooting MaxxFan That Beeps and Has Flashing Green Light
    I'll start off by saying that typically the flashing green lights on your MaxxFan # MA00-04000K means that there is some sort of voltage issue and even though when you tested you're getting what seems to be proper voltage, I would guess there is a short on the circuit that is causing the problem. I would recommend checking to make sure that the ground is properly attached to an area of the coach that is free from dirt, debris and corrosion. This would also be a good time to make sure...
