Frigidaire Wall Oven Repair in Toronto — Oven temperature inaccurate

• The defining temp-inaccurate fault on an Electrolux-platform Frigidaire is RTD sensor DRIFT rather than a hard failure: the probe still reads, but it reads off-spec, so the EOC's idea of cavity temperature no longer matches reality and the food comes out under- or over-cooked with no error code (the hard sensor codes -- F30 open-probe, F31 shorted-probe -- only fire when the RTD opens or shorts, not when it merely drifts). We meter the RTD oven sensor 316217002 (PS820208, AP3363354) cold at its connector -- a healthy probe is roughly 1080 ohms at room temperature (about 1000-1100 acceptable; well under 900 or over 1200 ohms condemns it). A drifted-high reading makes the control under-fire and bake cold; drifted-low makes it over-fire and run hot. Anything well off 1080 gets the sensor, not the board.
• A Frigidaire that reads correct resistance AT the sensor body but wrong at the EOC plug is a harness fault masquerading as a bad probe -- the RTD wires run along the back of the cavity through every heat cycle, so a corroded pin or brittle conductor at the rear-wall connector adds resistance the control reads as a false temperature. We meter the probe AND the harness at the EOC end and compare: a discrepancy beyond about 10 ohms between the two readings (our own bench heuristic, not an OEM spec) condemns the harness/connector, not the in-spec sensor 316217002 -- and finding that corroded plug is far cheaper than swapping a good probe.
• A bent probe or a sensor tip resting against the cavity wall reads falsely high because it's sensing metal, not air -- the classic signature is an oven set to 350 that bakes like 400 (or swings wildly) with the RTD testing perfectly in-spec on a meter. We straighten the probe so it sits proud in the airstream and re-clip it off the wall before condemning any part; a kinked probe also fails the replacement in months, so position is checked first. This is a frequent free fix that a parts-cannon misses entirely.
• A consistent fixed offset -- the oven reliably cold (or hot) by a steady 25-50F with an in-spec RTD and good harness -- is calibration, not a failed part. Frigidaire EOCs allow a user offset: push Bake, turn the temperature up to 550F, then push and hold Bake until a 2-digit display appears ('00' is factory), adjustable +/-35F in 5F steps (minus sign = cooler). We recalibrate rather than parts-cannon, and if the offset already sits at its +/-35F limit and the oven is still off, that tells us to look harder at the sensor or harness.
• An oven that reads accurately at the START but drifts off as it runs -- accurate cold, wrong once hot -- points at the RTD degrading under load or a partial/grounding bake element 316075103 (PS438018, AP2125026; 2600W/240V) heating weakly so the cavity creeps toward setpoint and never quite holds. We watch the element glow (a dull element that won't go fully red under-heats with intact continuity) and re-meter the RTD warm; a probe that's in-spec cold but wanders hot is a degrading sensor that an LED-reading-vs-thermometer comparison exposes.
• On wall ovens and many freestanding ranges the temp-inaccurate sensor is the alternate-cavity RTD 316490000 (PS1528542, AP3963654; supersedes 316490002/003 and 1197392) -- the right alternate probe for 'temperature not in line with the LED reading' and 'oven too hot or not heating evenly,' same ~1080-ohm room-temp target as 316217002 but a different physical probe/lead. The closely-numbered 316490001 (PS1528543, AP3969435) is a SEPARATE, still-active alternate probe, NOT part of the 316490000 supersession chain -- which is exactly why we match the right RTD to the model/serial before ordering rather than assuming either number.
• A worn or crushed oven door gasket 318053103 (PS442156, AP2127815; ~79.5 inches with its 18 mounting clips) bleeds cavity heat at the seal, so a mechanically healthy oven with a good element and in-spec RTD still won't hold setpoint and over-cycles chasing it -- it bakes unevenly and runs cold near the door. On a 'runs cold but no code and the sensor checks out' Frigidaire we run a hand around the closed door for escaping heat and inspect the gasket for tears/hardening/gaps before touching any electronics.

Frigidaire oven temperature inaccurate in Toronto — the local specifics

• The recurring Toronto pattern on Frigidaire temp-inaccurate calls is a drifted RTD sensor with no error code -- owners report a Gallery or FFEF range that 'used to be fine' now under- or over-baking, and the fix lands on the 316217002 (or the alternate 316490000) far more often than on the board. The second-most-common is a free one: a probe knocked into the cavity wall (often after a rack swap or a clean) reading falsely high, and a steady-offset oven that just needs the Bake-pad recalibration -- both of which a meter and an oven thermometer prove before any part is sold.
• We bring the 316217002 and the alternate 316490000 RTD probes, the 316075103 bake element, the 318053103 door gasket, and a calibrated oven thermometer plus meter to verify reading-vs-actual on site -- so a drifted sensor, a corroded EOC-plug harness, a wall-touching probe, or a simple calibration offset is sorted in one visit without ordering, and the EOC 316418720 is left for model/serial order only if the sensor and harness both test good.
