Service Bulletins

On some models, ice may be noticeably forming on the freezer compartment walls and/or a ticking-rumbling noise may be heard from the freezer. The ice formation will appear larger closer to the evaporator cover. Inspection may lead to diagnosis of an open drain pan heater allowing the drain pan to overflow and fill with ice. Additionally, ice may have formed around or on the evaporator fan blade: a result of moisture dripping off the evaporator wiring harnesses, suction tube, or evaporator compartment ceiling.

Freezer compartment lighting may appear dim or the refrigerator compartment may have the upper light or a tower light not working. If the freezer lighting is dim, one of the tower LED boards may be found to be inoperable. Any inoperable LED board will have the correct operational voltage.
