What it means, first
Oven code E22 is the control reporting that the resistance it reads across the thermal sensor or the appliance control board and the wiring between them left the window the control accepts. You can clear the code and start again, but heating is held back until the reading comes back inside its window.
What this code is documented as meaning

|---|---|
| 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. |
Symptoms that travel with this code
- Temperature drifts, or the display disagrees with the food — A probe reading a few ohms off is still inside its window, so the cabinet runs cool or hot before the code ever latches.
- The fault comes and goes with temperature — An intermittent connection opens as the metal expands and closes again when it cools, which is why the code often arrives part-way through a long cycle.
- NEAR MISS - nothing heats and no code shows at all — That is a power or element fault rather than a reading fault, and it belongs on the page for that symptom.
Causes in the order they actually occur
- A loose or corroded connector at the sensor — Ranked first because it is the failure that needs no part: the probe is fine, the joint carrying its signal is not, and heat cycling at the back of the cavity is what works a pin loose.
- A chafed or pinched harness between the probe and the board — Third: a wire rubbed through against sheet metal reads exactly like a failed probe from the board's side, which is why the harness is checked before the board is condemned.
The order to work through it
- Power the machine down fully and see whether the code returns — Costs nothing and separates a latched one-off read from a live fault.
- Follow the harness for rub marks where it crosses metal — A witness mark tells you the fault is in the wire, not in the part at either end.
What to try before calling
- Clear the code with a full power-down — Switch the breaker off, let the control lose its stored state, then switch it back on and start a short cycle.
About 5 min
- Let the cavity reach room temperature before anything else — A hot resistance reading means nothing, and a hot cavity is the reason half of these codes cannot be diagnosed on the spot.
About 45 min
- STOP HERE if the next step is a meter across the probe terminals — That means a panel off and a connector back-probed, which is where an owner check ends and a service call begins.
Safety first, and it is not optional
Safety
Unplug the appliance or switch off its breaker before any panel comes off; a capacitor can hold a charge after the power is off. Everything in the procedure above stays outside the cabinet for that reason.
When to stop and call someone
Where an owner stops: call once the code survives a full power-down: a repeatable reading fault is a probe, a harness or a board, and telling those three apart needs a meter and the resistance table for that model line. And where nobody should wait at all: call straight away if you smell hot insulation or see discoloured wiring at the back — a connector hot enough to discolour is arcing, and that is a different and more urgent problem than the reading the code named.
