Fujitsu ASU30CLX Control Board
Your furnace or AC will not run at all without the board installed. The control board is made to control the gas valve, the igniter, most sensors as well as the blower all together. The board that you will choose must be compatible with both the make and model of HVAC system. You must be careful when you choose a replacement because of the many variances of systems.
Hints your Fujitsu control board is in dire straights
- The entire system has to be turned off and back on many times a day for it to kick in
- Air conditioner or furnace refuses to operate well
- There may be some sort of error code indicated directly somewhere on the circuit board
