LG LP090CEM Control Board
It is impossible for your furnace or air handler to even operate lest the circuit board is properly connected to the unit. The control board is created to oversee the gas valve, the igniter, the flame sensor as well as the blower all in one unit. Be absolutely sure when you choose a replacement due to so many small differences in models within certain brands. The correct control board should be compatible with both the brand and specific model of your LG LP090CEM unit.
How can I tell if my main board is failing?
- There seems to be some sort of code showing up on the circuit board
- The heating and cooling system will not initialize well
- The power to the system has to be powered down and back up many times a day for it to work
