Samsung Range Error Code E-22

E-22 on a Samsung range means the oven temperature sensor has shorted, producing a resistance reading that is too low for the control board to accept. The sensor is responsible for monitoring oven cavity temperature, and a shorted condition prevents accurate temperature regulation. The range will typically disable oven heating functions until the fault is resolved. The sensor or its wiring harness will need to be inspected and tested.

You should not use the oven while E-22 is active. The control board cannot accurately regulate oven temperature without a functioning sensor, which creates a risk of overheating. The surface burners on a gas or electric range may still function, but the oven should remain off until the sensor fault is corrected.

Disconnecting power to the range and restoring it may temporarily clear the E-22 display, but the code will return if the underlying sensor fault is still present. The control board will detect the out-of-range resistance reading again as soon as it resumes monitoring the sensor circuit. A permanent fix requires testing and replacing the faulty sensor or repairing the wiring harness.

A knowledgeable DIYer can diagnose this code by disconnecting power, removing the upper rear cover panel, and measuring the sensor resistance with a multimeter at room temperature. If the sensor resistance reads abnormally low or near zero, replacing the oven temperature sensor is a straightforward repair involving disconnecting the wiring connector and removing the sensor mounting screws. Always disconnect power before accessing internal components.

If the oven temperature sensor is the cause, replacement parts typically cost in the range of $15 to $60 depending on the specific Samsung model. If the repair is performed by a professional technician, total costs including labor are generally in the range of $100 to $250. Diagnosing and replacing the sensor yourself can significantly reduce the overall cost.
