My Whirlpool upright freezer began thawing foods on the upper shelves. I emptied the freezer and unplugged it for 36 hours. I plugged it back in and temp inside is only 48 degrees.
Answer Jeffrey, The basic checks are at the freezer door and gasket, especially along the top seal, check the shelves, make sure there are no articles blocking the air flow on the sides or back of the shelves. Listen and feel for the evaporator fan, is it running, can you feel the air blowing towards you from the grille. is there a heavy frost or ice built up on the lower back panel, indicating a defrost issue. Remove the front grille and check and clean any debris from the grille and condenser.
