1 Tepid Whirlpool side-by-side fridge and freezer
Model WRS325SDHZ01. The freezer temperature was running about 18°. The fridge was at 56°. The unit had recently been defrosted manually which suggests there’s a malfunction in the defrosting cycle. I checked the continuity on the heating coil and it appears fine though when I ran a test cycle, the coil did not become warm to the touch. The evaporator fan and condenser fan are running normally. The unit has a self diagnosis process and it that the defrost sensor is operating normally. There is no damper fan, only an air diverter, essentially an opening between the freezer and the fridge sides. There are two thermistors , one on the freezer side and one on the fridge side. Ohm readings on both thermistors are within range. The compressor seems to be operating normally. There are no strange noises coming from the unit.
After manually defrosting the unit again, about 12 hours later, the evaporator coils already had a heavy coating of frost on them. Is the control board the only other device that could be the issue? I’d hate to spend the money on a new control board if the problem could be something cheaper.
EDIT: I just came across someone else’s old post that suggested the evaporative coil defrost sensor may have detached from the coil, but I don’t see such a device listed in the parts. What would I look for?
