Nordyne E3EX-020H Control Board
The Nordyne E3EX-020H control board is made to oversee everything including the gas valve, the igniter, most sensors as well as the blower all in one unit. The entire heating and cooling system will not operate without the main control board correctly installed. A replacement board must have a matching part number consistent with both the make and model of your heating and cooling system. You should always be careful while picking a new replacement board due to so many small differences in systems.
Warnings your control board needs a replacement ASAP
- AC or heating system cannot operate properly
- Power to the control board has to be reset quite a lot for the furnace or AC to kick on
- When turned on, there is flashing code indicated somewhere on the board
