Nikhil for Model Number RF197ACRS/XAA The fresh food part of the fridge has not been able to maintain the temperature. The evaporator coil, when checked, has had a lot of ice and frost build up. In the past I have manually defrosted 3-4 times and cleared the drin but it repeats every month. I checked the defrost sensor and at room temperature the resistance was 5.1 ohm. The heater and the bimetal assembly has a resistance of 500 kohm or so and had continuity. The thermal fuse on the side of the evaporator coil had a resistance of 550 kohm. Is there anything else to verify or do be done to consider that the circuit board is the cause?? Thanks
Answer Nikhil. Based on the readings that you are getting then this issue will be a faulty main control board with everything checking ok. Read More... Answered by AppliancePartsPros.com | Wednesday, June 21, 2017
