Heat Controller EKTC09-1G Control Board
The control board is made to command the gas valve, the ignition igniter, all the various sensors as well as the air circulator all in one unit. Your air handler will be unable to function without the main control board installed as it should be according to the manufacturer. You must be sure while searching to pick up a replacement control board due to variances between HVAC systems. A matching board will have a part number that will match the brand and the model of your heating and cooling system.
What are some indications that my primary control board has a need to be replaced?
- The power to the system needs to be reset quite a lot for it to run correctly
- There may be an error code indicated somewhere on the circuit board
- Air conditioner or furnace will not do anything properly
