03 - TradePro Air Conditioner User Control and Display Board

The user control and display board allows the user to operate the unit by selecting fan speeds and cooling temperatures. If the board is defective, the air conditioner may be unable to run.

04 - TradePro Air Conditioner Selector Switch

The selector switch directs voltage to the fan motor. If the switch is faulty, the fan motor may not turn on and the air conditioner won't run. To determine if the selector switch is at fault, try making selections on the air conditioner’s control board. If the fan runs intermittently after you press a button, replace the selector switch. Additionally, if there is any arcing or smoke coming from the selector switch, replace it.

05 - Incoming Power Problem

Check to see if there is power to the air conditioner. One or more indicator lights on the control board should be illuminated. If there is no power to the air conditioner, check to see if a circuit breaker has tripped or a fuse has blown. Confirm the unit is plugged in and has power.
