Jenn-Air JMW2430IM 30 in Combination Microwave Wall Oven with True Convection F3E5 Error Fix: Self-Clean Over-Temperature with Door Locked

Error code F3E5 on the Jenn-Air JMW2430IM 30 in Combination Microwave Wall Oven with True Convection means: Self-Clean Over-Temperature with Door Locked. During the self-clean cycle, the oven exceeded the maximum allowed clean temperature with the door locked — the control has shut down the heating elements as a safety measure; allow the oven to cool completely before attempting to open the door; check the oven temperature sensor; check the oven door seal/gasket — a missing or damaged door gasket allows heat to escape, which paradoxically can cause the oven to overwork and exceed temperature limits in some areas; replace the gasket if damaged
