      First, make sure the condenser is clean. Check that the door or drawer is closing correctly and has not been left open. Also, verify the door or drawer gasket doesn't have any rips or tears. If icing is heavy, turn the unit off and use a hair dryer set on low, kept moving at all times, to melt the ice. Wipe up any water with a cloth or paper towel after melting the ice.
