I noticed my fridge always running and seems it never cycles off. Could this be the control board?
Answer Hello Jeff. You will need to check the thermistors and make sure they are good. If so, then you will need to check the control board on the unit. Also, make sure the condenser coils are clean on the unit.
My refrigerator ( frigidaire ) is giving me a failure code SY EF. What could be the problem?
Answer Hello Sergio. Error Code SY EF is the System Evaporator Fault.
This usually means there is NOT enough air flow over the sensor caused by a faulty sensor, or evaporator fan motor.
Would the inverter cause sy cf error code but still be power to display
Answer Gordon, Yes, this could occur. The "SY CF " error in the display indicates a system (sy) communication failure (cf). Presumably, the refrigerator is not cooling based on the inverter portion of you question. You'll need to check for the 12 VDC power supply to the inverter from the control board (across J3 pin 1 and J3 pin 2) and at the inverter board connector on the compressor.
