How to Replace a Maytag Range Temperature Sensor
When a Maytag oven overheats, underheats, or posts an F3-series code, the RTD temperature sensor has usually failed. The swap takes fifteen to twenty-five minutes and one screwdriver — but the trick is telling the permanently mounted RTD apart from the removable cooking probe so you replace the right part. A quick…
RTD sensor versus cooking probe#
Two things measure temperature on these ranges and they are not interchangeable. The RTD is a fixed metal rod in the upper-rear corner, screwed to the wall, that reports cavity air temperature for oven regulation. The precision cooking probe is a removable accessory you plug into a front port to read food's internal temperature. If the oven itself misbehaves, it is the RTD you are after — the probe only affects doneness readings.
Read the codes, then the resistance#
Maytag flags the sensor circuit with F3E0 for an open sensor, F3E1 for a short, and F3E2 when the cavity exceeds its limit — often because a low-reading sensor kept the element on. Confirm by disconnecting the sensor and metering it: at a 70°F room a good RTD reads about 1,080-1,100 ohms and climbs roughly two ohms per degree Fahrenheit. A reading well outside that band confirms the failure; a normal reading points instead at the wiring back to the board.

Remove and replace#
- Cut power at the breaker and let the oven cool.
- Back out the one or two screws at the base of the rod in the upper-rear wall.
- Pull the sensor forward for a couple inches of slack, then press the tab and unplug the harness.
- Clip the new sensor's plug together until it locks, then feed the slack back so no wire dangles near an element.
- Mount the rod on the same holes; it must hang free, touching no wall, rack, or ceiling, since it reads air rather than metal.
Verify on the platform standard#
Restore power, clear the F3 code, and bake at 350°F. A center-rack thermometer should settle within about 10°F after twenty minutes. Because Maytag shares the Whirlpool Corporation sensor platform, the same part, mounting, and resistance spec carry across Maytag, Whirlpool, and KitchenAid, so a cross-referenced replacement fits as long as the connector style matches.
