What does Kenmore Oven Heats Too Hot - Causes & Fix mean?

Most often a failed oven temperature sensor sending incorrect readings to the control board. Test sensor resistance at room temp.

How do I fix Kenmore Oven Heats Too Hot - Causes & Fix?

Work through the step-by-step fix below. Start with the quick reset and the most common cause, then check the specific part this guide points to. Most fixes need only basic hand tools and the right replacement part.

Can I keep using my Kenmore appliance with this error showing?

Usually not. Kenmore appliances show this error when a part or safety circuit is out of range, so running it can stop the cycle or make the problem worse. Diagnose and clear the error before normal use.

What part is most commonly replaced for Kenmore Oven Heats Too Hot - Causes & Fix?

The parts that most often fix Kenmore Oven Heats Too Hot - Causes & Fix are listed in the parts section of this guide. Match the part to your exact model and serial number before you buy.

Is Kenmore Oven Heats Too Hot - Causes & Fix a DIY repair or do I need a technician?

Many fixes are DIY-friendly with basic tools, such as door switches, drain pumps, water inlet valves, thermostats, heating elements, and filters. Sealed-system, refrigerant, gas, or high-voltage work should go to a licensed technician for safety.

Kenmore Oven Heats Too Hot - Causes & Fix

Kenmore Oven Heats Too Hot — What’s Happening

When your Kenmore oven heats hotter than the set temperature, the control board is either receiving false high-temperature signals or a relay is stuck, keeping power applied to the bake element when it should cycle off. This symptom often triggers an F10 fault code, which means the control detects a runaway temperature condition.

The oven may actually overheat and burn food, or the control may simply think it is overheating due to a bad sensor reading. Either way, the root cause is usually in the temperature sensing circuit or the control board relay that switches bake power on and off.

Most Likely Causes

Failed oven temperature sensor The sensor probe sends resistance values to the control board, and when it drifts out of spec the board thinks the oven is cooler or hotter than reality, causing overheating or fault codes.
Stuck relay on the electronic control board If the relay that controls power to the bake element welds closed, the element stays energized even when the control tries to shut it off, and the oven climbs past setpoint.
Loose or damaged sensor wiring and connectors Corroded terminals, broken wires, or loose plugs between the sensor and control board create intermittent or false resistance readings that confuse the control.
Blocked oven vents or poor airflow If the vent system is obstructed or the range is installed too close to walls or cabinetry, heat buildup can push internal temperatures beyond normal and trigger overheat protection.
Failed electronic control board Beyond stuck relays, the control board itself can fail and misinterpret sensor signals or lose accurate temperature tracking, leading to runaway heating.

How to Diagnose and Fix

Turn off power at the circuit breaker or unplug the range, wait 30 seconds, restore power, and test whether the symptom or fault returns on the next bake cycle.
Check that all oven vents are clear and that the range is installed with proper clearance to walls and cabinets so heat can escape normally.
Locate the oven temperature sensor probe inside the oven cavity (usually a metal tube at the upper rear wall) and disconnect its wire harness at the back of the range.
Set a multimeter to measure resistance and probe the two sensor terminals at room temperature (around 70°F or 21°C), looking for a reading between 1,075 and 1,085 ohms.
Inspect the sensor wire harness and connector for corrosion, burns, or loose pins, and verify continuity through each wire from sensor to control board.
If the sensor reads out of range or the wiring is damaged, replace the sensor probe and retest temperature behavior with an oven thermometer.
If the sensor and wiring test good but the oven still overheats or stays on when the cycle ends, replace the electronic control board because a stuck relay is the likely fault.
Reassemble all panels, run a normal bake cycle at 350°F, and verify with an oven thermometer that actual temperature matches the setpoint within 25°F.

When to Call a Pro

If you are not comfortable working inside a live 240-volt appliance, call a technician. High-voltage connections behind the control panel and at the terminal block can cause serious shock or arc-flash injury. A qualified appliance repair tech has the meters, safety training, and genuine or cross-referenced Kenmore parts to diagnose sensor circuits and swap control boards safely. If your range is still under warranty or you lack a multimeter and basic hand tools, professional service is the safest route. For gas line, burner, or igniter work, or if you ever smell gas, stop and call a licensed technician.
