Carrier 58MXA100F14120 Control Board
HVAC systems will not operate whatsoever without the board installed. The Carrier 58MXA100F14120 control board is constructed to control everything including the gas valve, the igniter, the flame sensor and the blower all together. It is of utmost importance when you are choosing a replacement board due to the many differences between certain brands. A control board that you have chosen will have to be compatible with both the brand and model of air handler system you have.
Signs your Carrier control board is not going to last much longer
- The AC or furnace cannot run well
- Power to the circuit board has to be turned off and back on rather frequently for the heating or cooling to kick in
- System has flashing code suddenly appearing on the front of the control board
