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..
This is a replacement for the circuit board in the MAXXAIR 00-06200K. Overall great fan, however the circuit is a bit touchy with incoming voltage (more on that below). The original circuit that the fan came with worked fine for a a couple of seasons, then would stop and beep several times before limiting fan speed on. I dealt with it for a while, but it was rather annoying that the fan could no longer run at full speed. Talking with MaxxAir, the board seemed to be going bad...hence the replacement. I will only speculate that because the board is not coated, and where it is placed (bathroom) that the moisture eventually got to it and started causing errors. With this replacement, I sprayed it with a coating to prevent any moisture from getting to the electronics and it has been running fine. No issues, annoying beeps, or unexpected stops.
On a side note, I did upgrade to lithium later and would recommend installation of a DC-DC regulator with an ouput of 12V/5A/60W to keep the board happy. Since then I have not had any issues with the fan and it runs perfectly.
Bonjour,
Malheureusement, j’avais commandé la pièce # MA10A21276k et j’ai reçu une pièce portant le numéro 10C21276K, pièce que j’avais essayé auparavant et qui ne fonctionnait pas.
Nous l’avons quand même essayé, mais ça ne fonctionnait pas comme l’autre pièce du même numéro que j’avais commandé ailleurs, antérieurement.
Je voudrais vous la retourner et me faire rembourser. De plus, lorsque j’ai reçu la pièce, j’ai dû payer du dédouanage. Ce serait gentil d’aviser les clients de ces frais supplémentaires.
Merci et Bonne journée!
Part worked perfect. I bought this as I was getting intermittent green blinking light followed by a loss of power. This happened after I went to a lithium battery. As others have said, the volts are higher and older models are said to not like volts over 12.8 or so. I hooked it up. Was very easy to do. And, ran it for about 2 hours. Ran it on all speeds and also changed directions. No issues. I'm going on a 4500 mile trip. So, that'll be the real test! If I have issues I'll re post.

I appreciate the reminder to update my review as I forgot to. It turned out the circuit board was fine. The first night on my long trip the fan did the same thing. Once I got to my destination across the country I also tried a voltage regulator. That didnt work. I bought a new fan motor. It was ready to swap out without taking the fan apart. Its been flawless ever since! So, I basically have a new fan now.
Well, when my Max Air wouldn't start by pressing the button I thought it was a circuit board but it turned out it was only the keypad which is a separate item. well now I've got an extra circuit board.
The circuit board only lasted a couple of months. Very disappointed with the products from this manufacturer. etrailer I’m very happy with, this has nothing to do with etrailer. Fortunately I have a bit of electronics skill and was able to replace all of this with my own circuit board, a potentiometer and two switches. Works better and continues to work, at a cost of 10% of this product. This was the second board from Maxxair that had failed. Both had been running on regulated 12.5V.
The packaged arrived but was not padded very well or protected as this is a circuit board I thought it would have been protected more. One tab on the circuit board was bent. I sure hope it works when I get install in a few days.

Hey Bret. If you have any issues when installing please let me know. I can get a replacement shipped out to you ASAP for you if needed.
Unfortunately I did not have a great experience. It work for a month or so after installation. Then it only allowed the first two speeds to function. Based on my research I feel the control board is flawed by design. The form factor of the fan is the best out there, but there is no shortage of people who report that the fan stops working and starts beeping. It's too bad they haven’t figured out a solution.
Worked like a charm! Easy to install. Took less than 30 mins got the fan working again.
I give the part a solid 5. Part worked, hooked right up and made the fan blow again. That part was awesome. Looks exactly like the old one.
But for the first time etrailer really let me down. this is a sensitive part, brittle with pins sticking off of it. So they stick it in a zipper bag, then wrap it with a thin layer of bubble wrap and put it in an envelope. This deserved a little box.
Worked great - perfect repair. Easy ins tallation.
Works like a champ.
This new part fixed the shut down problem I was having with our Maxxair 5000
All good - been working well for 10months now
Purchased to replace a bad board and this one didn't even last 3 months.
Unreliable.
Solved the blinking green light of death. Took about 20 minutes to replace.
package arrived unbroke & ok, thanks
Our Maxxfan had a flashing green light and beeping from the unit. Thanks to your on line trouble shooting help, it told us when you have this issue, you need to replace the circuit board. Again, through your online help info, it told us the part number the circuit board we needed for our 4000k Maxxfan. I paid for faster shipping and received the circuit board in 2 days. The extra shipping fee was worth the price. The circuit board was easy to replace and we are up and running again. This fan is in our bedroom and we use it constantly when we RV. A very happy customer!
I replace the circuit board after the original one stopped working, the new circuit board worked a few times then it broke,
I then saw on utube what I should purchase and replace the switch with, Adjustable Reversible Switch 1203BB DC Motor Driver Reversing
Works great now. Do not need temperature gauge on original part.
This review is for their outstanding customer service. Very friendly and patient staff. I’d definitely order from Etrailer again. I highly recommend them. Thanks!
Our original fan started to alarm in the middle of the night. I replaced this circuit board in under an hour. It was super easy. I have no prior experience, just watched a couple of You-tube videos. It has been a year, and the fan functioned beautifully through several camping trips.
Installed and working perfectly!
Board itself is fine and works though given that they're prone to crapping out when taking on moisture they should come coated in a polyurethane spray. As for etrailers, the customer service is excellent.
Parts were exact duplicate and fixed the problem. The fan would turn on then stop with an error. These parts corrected the problem.
products arrived on time and intact {maybe put printed circuit in a box some reviews said theirs arrived damaged} would recommend etrailer
Just like the pic shows plug and play. Oh except the wire connections needed to plug to trailer wires. These should be included.
Quick shipping and the product worked like a charm.
I did follow forum suggestions and coat it in Poly before installing to make it extra waterproof to avoid any future water damage.

It has been a year, and circuit board has been working fine. The addition of a voltage regulator that caps the voltage to 12V has been invaluable.
