LG LMU240CE Control Board
The control board is constructed to command the gas valve, the igniter, the flame sensor as well as the blower all in one unit. Your furnace or AC will not function lest the circuit board is in connected and operational. You should always be careful when you are choosing a replacement board due to the many differences between models and types. The chosen circuit board will need to be a match with your existing board and be compatible with both the make and model of the unit you have installed.
What are some hints that my HVAC circuit board is on its last leg?
- There seems to be a type of code directly on the control board
- Everything has to be powered down and back up many times a week for everything to run again
- Entire unit ceases to run period

Before buying or ordering, do your due diligence and cross-check the model number and also make a visual comparison so that you are positive that the correct control board is the one being purchased. You do not need to install the replacement part alone. Find a professional locally to do the job for you.
