Whirlpool Whirlpool WFE775H0HZ 6.4 cu. ft. Smart Slide-In Electric Range MECH-DOOR-SEAL Error Fix: Oven Door Not Sealing / Heat Escaping

Error code MECH-DOOR-SEAL on the Whirlpool Whirlpool WFE775H0HZ 6.4 cu. ft. Smart Slide-In Electric Range means: Oven Door Not Sealing / Heat Escaping. The oven door does not seal properly, allowing heat to escape. The door gasket (fiberglass rope seal around the oven door perimeter) is worn, torn, or missing sections. Heat escaping from the door causes the oven to run longer, waste energy, and can discolor or damage surrounding cabinetry. Replace the door gasket — it is typically held in place by clips or slotted into a channel. Also check the door hinges — worn hinges prevent the door from closing tightly. Spring-loaded hinge replacements are available.
