E22 in plain terms
E22 means the control board reads the thermal sensor circuit as shorted, a resistance lower than any real oven temperature could produce. The control cannot trust that reading, so treat the oven as out of service for cooking until the code clears and stays clear.

|---|---|
| E22 | The Thermal Sensor circuit reported a short to the control board. There may a problem with the Thermal Sensor, the Appliance Control Board, or the associated wiring. |
What you see with E22
- E22 and no bake or broil heat — The control will not heat on a reading it cannot believe.
- The code appears only once the oven is hot — Softened insulation near a hot spot can close a short as it expands, so a cold oven may test fine.
- A faint burnt-plastic smell at the back of the range — Heat-damaged insulation often announces itself this way.
- E22 right after a deep clean — Liquid cleaner around the sensor's entry point can bridge its terminals until it dries.
Causes of E22, ranked
- A failed thermal sensor — First: after years of heat cycling the element can break down internally and short rather than open.
- Damaged insulation touching metal — Second, and common after a move: a lead pinched as the range was pushed back wears through.
- Contamination in the connector — Grease, cleaner or condensation bridges the terminals; a code that clears as it dries is the giveaway.
- The Appliance Control Board's sensor input — Last: considered only once the sensor and wiring are cleared.
What to check first for E22
- Power down and let the oven cool fully — A short caused by heat or moisture may clear cold, which tells you which branch to follow.
- Smell and look at the back of the range — Browned insulation points to the wiring before any part is ordered.
- Check the sensor connector — Once eased forward, a dirty or damp connector is cleaned, dried and retested.
- Measure the sensor, then the leads to ground — This tells a technician whether the short is in the sensor or the harness.
What an owner can safely do about E22
- Reset at the breaker — Breaker off for a minute, then on; watch whether E22 returns at once or only as the oven heats.
Tools: breaker panel accessAbout 3 min
- Dry out after cleaning — If the code followed a cleaning, leave the power off and the door open so liquid around the sensor can evaporate.
About 60 min
- Inspect the lead and connector — Oven cold and power off: remove the sensor's screws, ease it forward, and look for blackened terminals or flattened insulation.
Tools: screwdriver, flashlightAbout 15 min
- Leave the harness to a technician — Tracing a short means pulling the range out and working beside line-voltage connections.
Safety before you start
Safety
Switch off the breaker or unplug the range before removing the sensor screws or any panel; a capacitor can hold a charge after the power is off. If you smell burning plastic, keep the power off until the range is inspected. On a gas range, if you smell gas, do not switch anything on or off, leave the building, and call the gas utility or emergency services from outside.
When to book a service call for E22
Call if E22 returns once the oven is dry and cold, if you find melted insulation, or if the range must be pulled out to reach the wiring. A short is the sensor fault most likely to have damaged something else, so have the harness checked rather than swapping parts in turn.
