How do I know if my oven temperature is off?

Buy a $12 oven thermometer at any hardware store. Set the oven to 350°F, wait the full preheat plus 20 minutes (let it thermally equilibrate), then read the thermometer through the window — don't open the door. Anything within ±15°F is normal cycling. ±15–35°F is calibration. More than 35°F or temperature that wanders during the bake means the sensor has failed.

Can I calibrate my oven myself?

Yes — every modern oven supports a ±35°F calibration offset. Whirlpool: hold Bake + 350°F for 3 seconds. GE: Settings > Calibrate. Samsung/LG: User Settings > Oven Adjust. Owner's manual has your model's specific steps. Anything beyond ±35°F means the sensor is bad and calibration won't fix it.

Why does my oven run hot or cold?

Three suspects: (1) failed temperature sensor — most common, $195–$285; (2) calibration offset got bumped — free fix; (3) door gasket leaks heat during long bakes — $185–$265. Run the $12 thermometer test first; the result tells us what to load on the truck.

How much will it cost to repair?

Sensor $195–$285, bake/broil element $215–$305, gasket $185–$265, convection fan $285–$385. Calibration in service mode is free. Trip fee $149 waived on approval. Sensors, elements, and gaskets ride on every truck so most repairs finish first visit.

How fast can you come out?

Same-day windows weekdays in Minneapolis when you call before 2pm. Call with your thermometer readings ('set 350, read 405') and we'll arrive with the right part.

Is it worth fixing vs replacing?

Almost always fix. A $195–$285 sensor on a 5-year-old electric range is a quarter the cost of a new range. Replacement threshold: unit over 12 years old needing convection fan + control board, or a wall oven with cabinet damage. Honest answer at the door.

Oven Temperature Wrong? Diagnose With a $12 Thermometer

An oven baking 50°F off setpoint is almost always a failed temperature sensor, a miscalibrated control, or a weak bake element — not a failed control board. A $12 oven thermometer and a 30-minute bake test tells you which one. Below: what we find first across every Minneapolis ZIP, and the test to run before we roll a truck.

What we fix in Minneapolis

The Minneapolis repair mix

Failed oven temperature sensor / RTD (most common)

Stainless probe on the back wall drifts out of spec. Cavity overshoots or undershoots by 50–100°F and often wanders mid-bake. $195–$285 OEM replacement, 20-minute repair.

Calibration offset (5-minute DIY in service mode)

Every modern oven supports ±35°F calibration. Whirlpool: hold Bake + 350 for 3 seconds. GE: Settings > Calibrate. Samsung/LG: User Settings > Oven Adjust. Free fix if the sensor reads within spec.

Bake element open (bottom of food doesn't brown)

Lower horseshoe element opens internally. Oven preheats slowly, broil works fine. $215–$305 OEM replacement, 15-minute repair.

Broil element open (top of food doesn't brown)

Upper element opens. Bake works, broil produces no sear. Same access pattern, $215–$305.

Door gasket compromised (loses heat during long bakes)

Hardened or torn perimeter seal lets cavity heat leak. Convection fan runs more, side-to-side uneven browning. $185–$265 OEM replacement.

Convection fan slow or failed (true-convection units)

Bosch, Samsung, LG, KitchenAid Pro. Bearings seize or windings short. Hot spots, side-to-side uneven browning, audible whine. $285–$385 motor + bearing kit.

Field-service notes on oven repair

Oven Repair in the Twin Cities has its own rhythm — a repeating set of failures we see week after week. The Twin Cities humidity swing — dry January to sticky July — cycles refrigerator door gaskets hard; a gasket that seals in March can pull ambient air by August and drive up compressor run time 15–20%.

Because this page focuses on failed oven temperature sensor / rtd (most common), our tech opens the call by isolating that subsystem before touching anything else. OEM parts get sourced from Marcone, Reliable Parts, and 1st Source — never Amazon or eBay for anything sealed-system, control, or safety-critical. The $149 residential diagnostic is credited toward the repair if you approve; if you don't, you pay only the diagnostic and we leave a written scope. Every completed repair carries a 1-year parts and labor warranty in writing. The section above covers the specific failure surface — stainless probe on the back wall drifts out of spec.

Most first-visit calls close same-day for common failure modes; parts-return trips are typically 2–4 business days when we need a factory-only component. We're EPA 608 certified for sealed-system and refrigerant work, licensed and insured in Minnesota, and every tech carries a factory diagnostic laptop for brand-specific service modes. If the model is out of parts support, we'll say so on the first call and refund the diagnostic — that's the honest read on a repair-vs-replace decision, and it's the same read we'd give a family member calling about the same oven.
