Kenmore 661623920 Control Board
Heating and cooling systems will not even operate without the main control board configured and seated properly. The Kenmore 661623920 control board is made to operate everything including the gas valve, the ignition igniter, the flame sensor as well as the air circulator all together. The chosen circuit board will have a matching part number that will fit in the brand and the model of furnace or air handler you have. Be very careful when you are deciding on a replacement due to differences in models and types.
How do you know if your main circuit board is almost dead?
- There may be a fault code shown directly on the circuit board
- Power to the circuit board has to be turned off and back on a lot for it to run
- Entire unit is not able to start period
