Frigidaire Wall Oven Repair in Toronto — Self-clean won't start, or door locked after self-clean

• The signature Frigidaire self-clean-stuck fault is F90 -- the EOC commanded the door to unlock after the pyrolytic cycle but the lock motor did not reach the unlocked position within the allowed time, so the cycle aborts and the door stays latched. On the Electrolux NA platform the failure point is almost always the door-lock motor & switch assembly 5304528973 (PS16555576, AP7017733; supersedes 316464300/316137500/316415400/7316464300), not the EOC. We recycle the latch first (start Self-Clean ~15-30s, then press Cancel to command an unlock and re-home the cam), and if F90 returns we meter the lock-motor microswitch wiring back to the EOC before ordering the assembly.
• Frigidaire splits the lock fault into a five-code family and the exact code tells us where in the lock cycle it failed: F90 = max door-UNLOCK time exceeded, F91 = max unlock ATTEMPTS exceeded, F92 = max door-OPEN time exceeded, F93 = max door-LOCK time exceeded, F94 = max lock ATTEMPTS exceeded. F90/F91 (won't unlock after a clean) and F93/F94 (won't lock to start a clean) are both the same door-lock motor & switch assembly 5304528973 -- the difference is direction of travel. We read the precise code before quoting, because an F92 'door-open time' fault points at a switch/alignment issue rather than a dead lock motor.
• A lock cam that is physically bound by charred debris or warp mimics a failed motor and throws the same F90/F93. Pyrolytic self-clean drives the cavity to roughly 880F and bakes spills into ash that migrates into the latch travel; the motor energizes but the cam can't seat or release. We clear the latch and hinge path and check cam/rod travel before condemning 5304528973 -- a free fix that saves an unnecessary lock-assembly swap, exactly the discipline that separates a binding cam from a dead lock coil.
• A Frigidaire that runs Self-Clean and then goes completely dead -- no display, door still locked -- is the cavity thermal fuse / thermal limiter blowing under self-clean heat, not a control failure. These are non-resettable one-shot fuses: 5304506123 on wall ovens (replaces 318944000) and 318004902 on freestanding ranges. We meter the fuse for continuity (open = blown), replace it, and only then can the lock release. Restoring power without finding why the cavity overheated just blows the next fuse, so we check the RTD and the latch seal before re-energizing.
• F10 surfacing during or right after a self-clean run is the runaway/overheat code and the dangerous case: the cavity is reading past the safe limit. Most often this is the RTD oven sensor 316217002 (PS820208, AP3363354) drifting under the extreme self-clean heat -- a healthy probe reads about 1080 ohms at room temperature (roughly 1000-1100 acceptable), and a reading well off that condemns the sensor. But if the element stays hot with the oven commanded off, that is a welded-closed bake/broil relay in the EOC 316418720 (PS977998, AP3781481), a genuine fire risk that is never reset-and-returned -- we prove drifted-sensor vs. welded-relay on a meter before re-energizing.
• F30 (open RTD circuit) commonly appears after a self-clean cycle because the high-heat run stresses the sensor circuit and its connector: the probe can read in-spec at the sensor body yet open at the EOC plug where heat has corroded or backed-out a pin. We meter the RTD 316217002 AND the harness at the rear cavity wall before ordering, since a heat-damaged/backed-out connector throws F30 (an open) -- while a pinched or melted-insulation harness shorting below ~500 ohms throws the companion code F31 (shorted RTD). A heat-damaged harness throws the identical fault and is cheaper to find than replacing a good sensor.
• A self-clean-induced no-heat that is NOT a lock or sensor fault traces back to the heat path: the pyrolytic temperature can break the bake element 316075103 (PS438018, AP2125026 -- dual-rated 2600W @ 240V / 1950W @ 208V; supersedes the older 316075104, AP4356505, PS2332301) or trip the thermal limiter. If the surface burners and clock still work but the oven won't heat after a self-clean, we test the element for continuity and the thermal cut-out before touching the EOC -- the extreme cavity heat takes out the element or the fuse far more often than the control board.

Frigidaire self-clean won't start, or door locked after self-clean in Toronto — the local specifics

• The recurring Toronto pattern is the holiday-season Frigidaire stuck latch: owners run Self-Clean before a big meal, the door locks for the pyrolytic cycle and then won't release, throwing F90. The other steady pattern is the 'died right after self-clean' call -- a completely dead panel with the door still locked -- which is the cavity thermal fuse blowing rather than a board fault. We see the binding-cam-from-ash version most on older FFEF/FGEF ranges that have not been self-cleaned in years, where baked-on debris jams the latch travel and mimics a dead lock motor.
• We roll to these calls with the door-lock motor & switch assembly 5304528973 (the F90/F91/F93/F94 fix), the RTD sensor 316217002 (for the F10/F30-after-self-clean drift), and both thermal fuses -- 5304506123 for wall ovens and 318004902 for freestanding ranges -- so a stuck-latch or dead-after-clean diagnosis can usually be closed in one visit. We carry a meter to prove drifted-sensor vs. welded-EOC-relay before re-energizing, and we leave the model-coded EOC 316418720 to a dealer-order/repair second trip only when the lock, fuse, and sensor all test good.
