Jenn-Air JJW2830IM Wall Oven 30 in 4.1 cu ft Single Wall Oven with True Convection and Self-Clean F3E2 Error Fix: Oven Over-Temperature (Runaway)

Error code F3E2 on the Jenn-Air JJW2830IM Wall Oven 30 in 4.1 cu ft Single Wall Oven with True Convection and Self-Clean means: Oven Over-Temperature (Runaway). The oven temperature has exceeded the maximum safe threshold — approximately 665°F in bake mode or 990°F in self-clean; this is a POTENTIALLY DANGEROUS condition; turn off the oven immediately and disconnect power at the breaker; the most common cause is a stuck/welded bake or broil relay on the EOC board — the relay contacts fused closed, providing continuous power to the heating element even when the control commands it off; check the oven sensor accuracy; if a relay is stuck, the EOC MUST be replaced immediately — a stuck relay is a fire hazard
