Field pattern: 'oven runs hot / cold' (measure the average and calibrate before buying a sensor)

Ovens cycle above and below the set point, so a single thermometer reading misleads. Techs average readings over several cycles, use the control's temperature offset for small errors, and only replace the sensor when it fails a resistance test or the error is beyond the offset range. Replacing a good sensor (or a control) on a calibration complaint is the common wrong turn.

Guide · Range / Oven

Electric range trips the breaker or blows a fuse

Use the timing of the trip to split the problem. A trip at power-up, with every control off, points to the supply cord, terminal block, internal wiring or the breaker itself. A trip only when one element or mode is turned on points to that element (usually shorted to its sheath) or its switch and wiring. Rule out a weak or undersized breaker last, after the range itself tests clean.

Electric range partly works: display on, oven or big elements won't heat

An electric range runs its electronics and lights on 120 V (one hot leg to neutral) but heats with 240 V across both legs. If one leg is lost, the range looks alive but cannot heat properly. Typical causes are half of the double-pole breaker tripped or failed, a burned terminal block or cord connection, or a damaged receptacle. A building on 208 V will heat, just more slowly.

Oven keeps heating when turned off or overheats past setpoint

This is a fire hazard: turn the breaker off first, then diagnose. On electronic controls the usual cause is a relay on the control board whose contacts have welded closed. On dial ovens it is a stuck thermostat or selector contact. Less often a shorted sensor or harness is to blame. On gas ovens, a burner that won't shut off is a gas-valve problem and goes to a licensed gas technician.
