If the Broan Air Cleaner wall control is not working, ensure the color-coded wires are correctly connected. Inspect all wires for damage and replace any that are broken. To further test, remove the wall control and test it directly beside the unit with a shorter wire. If it works, replace the original wire; if it still doesn't work, replace the wall control.
How to fix a Broan HRV90H with a damper actuator that does not work?
If the damper actuator on your Broan Air Cleaner isn't working, start by unplugging the unit and disconnecting the main and auxiliary controls. Wait 10 seconds, then plug it back in to see if the damper opens. If not, use a multimeter to check for 24 VAC on J12-1 and J12-2 on the circuit board. If there is 24 VAC, replace the entire damper assembly. Note that a small delay of 7-8 seconds is normal before the 24 VAC signal appears, and it will last for 17-18 seconds. If there is no 24 VAC, replace the circuit board.
What to do if the Broan Air Cleaner humidity control doesn't work?
If the humidity control or the 20-minute push button timer on your Broan Air Cleaner isn't working, or its indicator light doesn't stay on, first ensure the color-coded wires are correctly connected. Then, jump the OL and OC terminals. If the unit switches to high speed, remove the dehumidistat or push button and test it right beside the unit using another shorter wire. If it works there, change the wire. If it doesn’t, change the dehumidistat or the push button.
What causes a Broan Air Cleaner's defrost cycle to fail?
If the defrost cycle isn't working on your Broan Air Cleaner, or if the fresh air is very cold, ice deposits may be hindering the damper's operation. Remove any ice that has formed. Inspect the damper rod and port damper for damage and replace them if necessary. You can also refer to point 2 for checking the damper actuator or circuit board.

The integrated control LED flashes RED; exhaust motor does not work on low speed but works on high speed. 5. The integrated control LED flashes RED; exhaust motor does not work on high speed but works on low speed. To troubleshoot, you can try the following: * Plug the supply motor to the J5 connector and the exhaust motor to the J4 connector. If the integrated control LED flashes RED, the supply motor is defective. If the exhaust motor works, plug the supply motor back to the J4 ...
