Door problems look cosmetic and cost more than most mechanical faults. A walk in gasket that has hardened and split lets warm humid air leak in continuously, which raises run time, ices the evaporator and shows up on your energy bill long before anyone notices the rubber. JRC repairs walk in and reach in doors across New Cumberland, WV.
We replace gaskets, closers, hinges and latches, and on freezer doors the perimeter heater wire that stops the door freezing shut. A door that has dropped on its hinges will never seal however new the gasket is, so we set the alignment first. The paper test is worth knowing: shut a note on the gasket and if it slides out freely, the seal has gone.
