Frigidaire Wall Oven Repair in Toronto — Not reaching or holding temperature (uneven baking)

• RTD oven temperature sensor drift is the number-one not-reaching-temp cause on Electrolux-platform Frigidaires: a sensor (316217002, PS820208) that has drifted high tells the EOC the cavity is already hot, so the control under-fires the bake element and the oven stalls below setpoint. We meter it cold first — a healthy RTD reads roughly 1080 ohms at room temperature — and anything well off that spec gets the sensor, not the board.
• An open or shorted RTD circuit stops the oven short of temperature to stay safe and throws an F3x sensor code: on this Frigidaire/Electrolux platform F30 is an open probe and F31 is a shorted probe. Either way we inspect the harness and the plug at the rear cavity wall for a pinched wire, moisture or a corroded pin before condemning sensor 316217002 — a connector fault mimics a dead probe and is cheaper to find first.
• A partially failed or grounding bake element (316075103, PS438018, AP2125026; push-on-terminal variant 316075104, AP4356505, PS2332301) heats weakly so the oven creeps toward temperature but never reaches it, or takes far too long to preheat. We look for a dull element that won't glow fully red and test continuity — a visible blister means replace, but a low-glow element with intact continuity can still be drawing wrong and under-heating.
• A consistent 25–50°F-low offset that holds steady is calibration, not a failed part. Frigidaire EOCs allow a ±35°F user offset (hold Bake about 8 seconds, then +/-). If the oven is reliably cold by a fixed amount and the RTD checks in-spec, we recalibrate rather than parts-cannon — and if the offset already sits at its limit we know to look harder at the sensor.
• A worn or crushed oven door gasket (318053103, AP2127815, PS442156 — ~80" with its 18 mounting clips) bleeds cavity heat, so a mechanically healthy oven with a good element and in-spec RTD still won't hold setpoint and over-cycles trying. On a 'runs cold but no code' Frigidaire we check the door seal and hinge closure before touching electronics.
• A failed-open EOC bake relay or a dead control board (EOC 316418720, PS977998 — NLA on many models, sourced by model/serial) gives no heat or weak heat with often no code or a generic lockout. This is the opposite of the F10 welded-relay overheat: here the relay won't close, so we confirm the element and RTD are good and that power reaches the element legs before quoting the board.

Frigidaire not reaching or holding temperature (uneven baking) in Toronto — the local specifics

• In Toronto the recurring not-reaching-temp Frigidaire pattern is a drifted RTD sensor reading high — the oven thinks it is hotter than it is and under-fires — far more often than a dead element, and a steady 'always runs cold' complaint usually turns out to be calibration offset or a worn door gasket bleeding heat rather than a failed board. We see the 'died right before a holiday bake' clustering too, since under-heating only gets noticed when something has to actually cook through.
• We roll to these calls carrying the 316217002 RTD sensor and both bake-element variants (316075103 and the push-on-terminal 316075104), plus a 318053103 door gasket — the parts that close out the large majority of Frigidaire under-heat jobs in one visit. The model/serial-coded EOC (316418720) is verified on a meter and then ordered, never guessed, because it is the four-figure-risk part on this platform.
