Freezer not freezing and no fan blowing into freezer compartment; fridge side freezing; fan works fine next to compressor; no water being dispensed ; unplugged it for any hour plus and all restarted fine but after a few minutes, all went back to the quiet sound of motor humming along but no compressor cycling on and off for freezer; still no water dispensed. Assume filter is clogged after years of using same one; need help on temp issues; Thanks everyone !!
