Carrier 50RQ Control Board
The control board is constructed to control everything including the gas valve, the igniter, all the sensors as well as the blower all at once. Heating and cooling systems will not even run without the control board in place and connected. Any control board you choose should be compatible with both the make and model of air handler system you have. You must be sure when you are choosing a replacement board due to variances between heating and cooling systems.
Major warnings of a deteriorating control board
- Power to the control board has to be reset quite a lot in order to run
- The unit cannot run correctly
- When turned on, there is a strange code revealed on the circuit board
