Panasonic CS-E9NKUAW Control Board
It is impossible for your furnace or air handler to even run at all unless this important circuit board is correctly installed. The Panasonic CS-E9NKUAW control board is constructed to control the gas valve, the ignition igniter, most sensors as well as the air circulator all at once. You must be sure when you are choosing a replacement board due to the vast differences in brands, models and types of systems. The selected board will have a part number that will match the brand and the model of the unit in question.
Major symptoms your primary control board is failing
- AC unit or heating unit is not able to initialize well
- There is a numbered error code indicated directly on the circuit board
- The HVAC system has to be turned off and back on a lot for it to run
