Quick Answer: Why Your Amana Oven Temperature Is Off#
Most likely: the temperature sensor (part WPW10181986) has drifted. It is the same Whirlpool sensor that reads about 1080 ohms at room temperature, and as it drifts it produces a 20 to 50°F offset — the oven simply runs hot or cold. Often the simpler answer is that the oven just needs a calibration adjustment, which Amana allows from the Settings menu. A bake element that has partially failed and now puts out reduced heat is the third cause, showing up as a steady undershoot. Confirm the fault with an oven thermometer before replacing anything, because a small offset is a settings fix rather than a repair.
Likely Causes at a Glance#
| Cause | Likelihood | What to check |
|---|---|---|
| Temperature sensor drift (WPW10181986) | Most likely | the Whirlpool sensor at about 1080 ohms room temp; drift gives a 20 to 50°F offset with no code |
| Calibration adjustment needed | Common | set an offset in Settings against a rack thermometer before replacing anything |
| Bake element partially failed | Occasional | reduced heat output causing a consistent undershoot; look for a dull or broken section |
| Door gasket leaking heat | Rare | a worn gasket bleeding heat and causing temperature swings |

Walking Through the Diagnosis#
Disconnect power at the breaker before any inspection, and on a gas model turn off the gas supply valve as well. Find the exact model on the serial plate — an AGR5330BAS is a gas unit that tends toward sensor drift, while an AER6303MFS is an electric unit that more often just needs calibration — and note any error code.
Verify the problem first: put an oven thermometer at the center rack, set 350°F, wait about thirty minutes past preheat, and compare, since small swings around the set point are normal and only a consistent gap of more than about 25 degrees is worth chasing. If the average is genuinely off, weigh sensor drift against a calibration need. The temperature sensor (WPW10181986) is the same Whirlpool probe that reads roughly 1080 ohms at room temperature, and when it drifts it produces a 20 to 50°F offset that throws no error code — the oven just runs wrong. Before replacing it, use Amana's calibration: open Settings, find Temperature Calibration, and adjust the offset in 5°F increments up to plus or minus 35°F, judging against your rack thermometer after a full stabilization rather than the first few minutes. If more than the adjustment range is needed to get it right, the sensor has drifted too far and should be replaced. When the oven runs consistently cold rather than simply offset, inspect the bake element for a dull spot or a break — a partially failed element puts out reduced heat and undershoots the set temperature.
How to Prevent This#
Wipe up spills promptly so carbonized residue does not skew heating, test oven accuracy every six months with a thermometer and recalibrate if it is off by more than about 25 degrees, and inspect the door gasket annually since a worn one leaks heat and destabilizes the temperature.

Repair or Replace? The Short Version#
A calibration adjustment costs nothing, and the temperature sensor is an inexpensive Whirlpool-platform part, so this never approaches a replace decision — a bake element is the only larger item, and even that is a targeted repair on an oven under eight to ten years old. Always try calibration before ordering parts. If metering the sensor or reaching the bake element is not for you, our technicians carry Amana parts and confirm the cause first — book a repair.
Frequently Asked Questions#
How do I calibrate my Amana oven?#
Open Settings, go to Temperature Calibration, and adjust the offset in 5°F increments up to plus or minus 35°F — the same Whirlpool procedure used across the platform. Determine the offset first with an oven thermometer at 350°F for thirty minutes, and set the calibration against that reading rather than guessing.
How much does Amana oven temperature repair cost?#
It varies by which part is at fault. A calibration adjustment is just a settings change, the temperature sensor (WPW10181986) is an inexpensive Whirlpool-platform part, and a bake element is the larger item. Most repairs take well under an hour on-site, and the diagnostic confirms which of the three is needed before any part is ordered.
Why is my Amana oven off but showing no error code?#
A drifting temperature sensor produces a 20 to 50°F offset without ever triggering a code, so the oven simply runs wrong while everything looks normal. Test the sensor (WPW10181986) for about 1080 ohms at room temperature and try a calibration offset before replacing it — a small gap is usually a settings fix.
My Amana oven runs cold even after calibration — what now?#
If calibration cannot bring it up and it consistently undershoots, suspect a partially failed bake element rather than the sensor. A dull or broken section of the element puts out reduced heat, so inspect it visually and confirm it glows evenly; a weak element should be replaced.
