Desa REM155B Control Board
Most systems will not function unless this board is hooked up and is correctly configured. The control board is constructed to direct the gas valve, the igniter, most sensors as well as the blower all at once. A matching board should have part numbers that match the brand and the model of your Desa REM155B unit. You must do some research while picking a new replacement board due to variances between systems.
What symptoms are present when the primary control board is dying?
- When turned on, there is flashing code showing up somewhere on the circuit board
- The control board has to be reset frequently for everything to run again
- AC unit or heating unit is unable to run well
