Video Transcript for Review of Maxxair RV Vents and Fans - MA39FR

Michael: Hi there. I'm Michael with etrailer.com. Today we're going to take a quick look at the replacement printed circuit boards for your Maxxair powered lift RV roof vents. As you can see, we've got two different boards here. These are the part numbers that you see on the screen there. Essentially these are exactly the same thing with one small difference between them.

If you look at the circuit board, you can see they have almost all of the same components except this large black box here. This is actually going to . allows this board to work for your Maxxair vents that are both exhaust and intake.This other one that does not have that box is only going to work with your Maxxair fans that are exhaust only. If your unit is able to bring air in as well as exhaust it out, you're going to need this one over here. If your unit is only capable of exhausting the air from inside your RV, this is the unit that you will need here.Keep those part numbers up there for you to make sure that you are getting the right one.

It's a pretty slight difference between them, but obviously it's going to have a big impact on their usability. We want to make sure that you're getting the product that you need. Just wanted to clear that up for you. Both of them are going to work with your Maxxair power. It's just that functionality difference that you need to look out for.

We're going to make sure that you knew the difference and are going to get the right chip that is going to work for you.That is going to complete our look at the Maxxair replacement printed circuit board. Again, I'm Michael with etrailer.com. Thanks for watching.

Perfect replacement. Works like new. My old control board ran the fan continuously and would not shut off. Installed the board and works as designed.

  • Maxxfan Deluxe 7000K Max Fan Input Voltage MA39FR
    The manufacturer (MaxxFan) would be the authority on the max input voltage of the # MA39FR. Since this was designed to be used on a 12 volt system a max voltage of 13.6 volts would be very reasonable all things considered. Some people may have gotten lucky with a 16 volt circuit that I would not consider that the norm and instead an exception.

  • Troubleshooting MaxxFan Deluxe Roof Vent MA00-07000K Lift Motor Opening Too Far
    I would be happy to help! I reached out to my contact at MaxxAir and the reason your lift motor opened up so much is do to you not having the lift arms connected. The way the circuit board on your # MA00-07000K works is by allowing the lift motor to work until it senses an amp draw due to resistance. Since you did not have the arms connected, the motor did not experience resistance and thus the circuit board did not stop the lift motor. This gave a false appearance of a bad circuit...

  • Troubleshooting MaxxFan MA00-07500K Deluxe Foof Vent Fan
    I spoke with the folks at Airexcel, who ran through a few different troubleshooting scenarios with me. As a first step, disconnect power to the fan for a few minutes, then reconnect power to reset the circuit board. If that fails to solve the problem, there are other things you can check. Can you operate the lid manually with the knob. If you cannot, it's an indication that either the mechanism is jammed or the lift motor is shorted out and needs replacing. A replacement lift motor is...

  • Which MaxxFan Circuit for MaxxFan with Electric Lift Arms and Rain Sensor
    Since your MaxxFan has powered lift arms and a rain sensor that would mean you have the # MA00-04751KSX and the required circuit board replacement is the part # MA39FR. At this time we do not have an install video we can share though.

  • MaxxFan MA00-4500K Vent Lid Will Not Open
    As a first step, disconnect power to the fan for a few minutes, then reconnect power to reset the circuit board # MA10A21275K. If the fan fails again it could be the circuit board. Your rain sensor could incorrectly think rain is present on the rain sensor # MA34FR. Unplug rain sensor, leave unplugged and try again. If it begins working, it could be the sensor. If you cannot open the lid manually it may be a jammed or stripped operator # MA10-20281K-1AF, or the lift motor is shorted...

  • Troubleshooting A MaxxAir MaxxFan That Opens But Doesn't Close
    If you already replaced the operator # MA10-20281K-1AF for your MaxxAir MaxxFan and it's working correctly to open but not close then the next part to replace would be the circuit board.

The Replacement Printed Circuit Board for MaxxAir Powered Lift RV Roof Vents w/ Reversible Fan # MA10A21275K is compatible with the following models: MaxxFan Plus: 00-04500K, 00-04700K, 00-04800K, and 00-04900K...

  • Troubleshooting A MaxxAir MaxxFan That Keeps Turning Off
    Your MaxxFan Plus Roof Vent w/ 12V Fan and Thermostat - Manual Lift - 10 Speed - White # MA00-04000K could be cutting off after 10 seconds for the following reasons: 1. Insufficient or fluctuating power. Your fan could be receiving less than 12v of power. Check the power wire at the unit using a multimeter like # PT89ZR. If you aren't receiving 12v then you could have a voltage drop off due to the length of the wire running from the battery to the fan and would just need to increase...
