LG LS-J0910CL Control Board
The control board is constructed to oversee everything including the gas valve, the ignition igniter, all the various sensors and the blower all in one unit. HVAC systems will not operate whatsoever unless this board is hooked up and is correctly configured. You should always be careful when choosing a control board due to the vast differences in models within certain brands. The proper control board should have a replacement part number that matches both the make and model of the system you have installed.
Symptoms of a barely functioning primary control board
- Power to the circuit board has to be powered down and back up often for the thermostat to kick in
- The heating and cooling system is not able to go period
- When turned on, there is flashing code displayed on the circuit board
