Nordyne E3EX-017H Control Board
The Nordyne E3EX-017H control board is constructed to operate the gas valve, the igniter, the flame sensor as well as the blower all in one unit. It is impossible for your furnace or air handler to even operate unless the control board is installed as it should be according to the manufacturer. It is imperative that you select wisely when you choose a control board due to differences in systems. A matching board must have a matching part number consistent with both the make and model of the system you have installed.
Symptoms your primary control board is in dire need of a replacement
- The system board has to be powered down and back up more often than not for the thermostat to kick in
- Air conditioning or heating system cannot do anything whatsoever
- There may be a strange code suddenly appearing on the board
