I have American Whirlpool S20BRSS31-A/G ( production label on photo 1 ). My fridge and freezer not cold. Fridge “clicking”, “beeping” etc ( screen on display photo 2 ). I repaired the rear board condenser and fridge not clicking, not beeping. It looks allright. Unfortunately, it does not cool. The engine works but does not shut off. May be a bad thermostat? Please HELP me.
