Question about Fujitsu 18C1 Air Conditioner

1 Answer

Fujitsu ASU9RLQ I have a new mini split heat pump/air conditoiner installed. The electronic air cleaner does not operate correctly. After 4-5 minutes of operation, the Operation (red) light on the front of the wall unit flashes 4 times and the Timer (grn) light flashes 7 times indicating an air cleaner monitor trial protection error. The filter is clean (new) and the front panel is closed. I'd appreciate advice re how to resolve the error.

My fujitsu mini split is tripping the circuit breaker on heat mode after a few minutes of operation. the a/c works fine. It makes a lot of noise just before tripping

If I had to guess you have a bad reversing valve. valve sticking, compressor not being able to pump refrigerant, then drawing high amps, overheating and tripping the breaker. If you have tools and experience, try tapping on the valve gently to free it up while switching.

I have a fujitsu aou24rml that i am installing in my house and the tag on the unit says 230/208 volts but the terminal block only has L and N witch i think is for 110 volt

Based on the specs that I could find, that unit requires 208/230 volts. Are you sure you are looking at the correct terminal block. It should be more like L1/L2. Do you have the install manual and does it tell where to hook up the supply voltage?
