International Comfort Products MB20N2600A2 Control Board
HVAC systems will not operate lest the circuit board is in its proper place and configured for your unit. The control board is constructed to command the gas valve, the igniter, most sensors and the blower all at once. The brand of board you choose will need to pair with the part number from both the brand and model of your particular system. You must do some research while picking a new replacement board due to the many differences between brand and air handler types.
What symptoms are present when the primary control board is on its last leg?
- When turned on, there is lit up error code indicated directly on the board
- Everything needs to be reset frequently for it to kick in
- Air conditioner or furnace is unable to initialize well
