Frigidaire FRS123LC1 Control Board
The control board is made to control the gas valve, the ignition igniter, all the sensors as well as the air circulator all at once. Your system definitely will not be able to function unless the control board is in place and connected. The board you choose must be compatible with both the brand and model of the system you have installed. You should always be careful when you are choosing a replacement board due to differences in models and types.
Main clues your main board needs a replacement ASAP
- Power to the control board has to be turned off and back on often in order to operate
- There may be a strange code instantly appearing somewhere on the circuit board
- The furnace or AC is unwilling to go at all
