My Frigidaire PHLS237ZDB1 side by side refrigerator has an ice/water dispenser that looks like it is shorting out. It was working fine up to yesterday when the exterior lights flash on and off, the dispenser does not work and it makes a clicking noise each time the lights flash on and off. I have unplugged the connector in the top hinge and obviously it shuts off the dispenser. When plugged back in the dispenser works for about 10 seconds then begins flashing again. Any idea what is going on? My thought is a circuit board. Any help would be great and any help in pulling out the dispenser if need be to repair I would really appreciate it.
