My fridge side is getting warm. In trouble shooting, I've taken the control section down as I was noticing an odd noise. Once opened up, I'm finding the cycling grinding has to do with the cold air being brought to the damper. When the noise happens, the air cycles on off. This blew my two original ideas of what it was being the damper and or damper control. I don't believe a thermostat would make it cycle rapidly then work again for a period of time then cause the same issue. Any help would greatly be appreciated.
