Blower motors turn on and off by itself. Control panel bad? Thanks
Answer Hello Dennis,
This could be the switch on the board 00415292 or a harness 00487459 shorting intermittently to ground, effectively bypassing the switch. Let's hope it is not the harness since it is unfortunately no longer available and no satisfactory substitution has been provided by the manufacturer.
The lights stopped working the fans still work, any suggestions on what it might be,the transformer or the control board circuitboard
You will want to test the transformer on the unit and ensure that there is 120 vac going into it and 12 vdc coming out of it to the lights. If there is 120 vac in but not the 12 vdc coming out then the transformer is faulty and would need to be replaced. If there is no power to the transformer then the control board is faulty.
