Carrier 58MXA140 Control Board
The system will cease to run at all lest the main control board is configured and seated properly. The Carrier 58MXA140 control board is constructed to control everything including the gas valve, the ignition igniter, all the various sensors and the blower all together. You must do some research when you choose a replacement due to the many differences between models within certain brands. The control board you choose will have to be compatible with the brand and the model of the unit in question.
General indicators that your control board is on its last leg
- Power to the circuit board has to be reset repeatedly for it to run correctly
- AC unit or heating unit refuses to initialize at all
- There seems to be a strange type of error code shown somewhere on the circuit board
