GE oven and range thermostats and sensors measure or control temperature in the oven cavity, cooktop, warming area, cooling system, or safety circuit. Mechanical thermostats switch contacts through a capillary sensing system, while electronic oven sensors send resistance information to a control board. High-limit thermostats and thermal switches protect components from abnormal heat.

An oven that seems too hot or cold does not automatically need a GE oven thermostat. Ovens normally cycle above and below the set point to maintain an average temperature, and readings change with thermometer placement, door openings, cookware, rack position, preheat, and convection conversion. Confirm a repeatable cooking problem before replacing a sensor or calibrating the control.

Separate normal temperature cycling from a component fault

Bake elements and burners turn on and off, so a single thermometer reading can catch the top or bottom of a normal cycle. Allow full preheat and evaluate results across multiple cycles or consistent bake tests. Frequent door opening releases heat, while dark pans and poor rack spacing can make food appear overcooked without a sensor fault.

Check GE oven and range heating elements or GE oven and range burners when one heat source never operates. A thermostat or sensor cannot compensate for a failed bake element, weak gas ignition system, blocked airflow, or damaged gasket.

Identify mechanical thermostats, electronic sensors, and limits

A mechanical oven thermostat commonly has a control shaft, electrical terminals, capillary tube, and sensing bulb. The capillary is a sealed component and must not be cut, kinked, sharply bent, or repaired. An electronic sensor is often a probe mounted through the rear cavity wall with a wire connector behind it. A limiter or thermal switch may be attached to a cooktop, panel, or cooling path.

Copy the complete part number and record the sensor location. Compare resistance specifications, temperature range, probe length, mounting flange, connector, wire length, capillary geometry, shaft, contact ratings, calibration design, reset behavior, and normally open or closed state where applicable.

A fault code can result from the sensor, connector, harness, or control input. Inspect GE oven and range wire harnesses for loose pins, heat damage, shorts, and opens before replacing a second sensor.

Test the complete sensing circuit

Disconnect power and isolate the component as required before resistance or continuity checks. Compare readings with the specified temperature chart or service procedure. Measure from the control connector when appropriate to include the harness, then test the sensor directly if the circuit is abnormal. This separates a probe fault from wiring resistance or a poor connector.

For a mechanical thermostat, check contact action and capillary condition using the designated procedure. Do not rotate calibration screws or bend the sensing bulb as a diagnostic shortcut. High-limit devices should not be bypassed; determine why the protected area overheated before replacement.

If the sensor input is correct but displayed temperature, relay output, or fault logic remains wrong, inspect GE oven and range control boards, capacitors, timers, and transformers.

Calibrate only after basic cooking conditions are correct

Some controls allow a temperature offset for consistent too-hot or too-cold results. Calibration changes the relationship between the set point and control target; it does not repair an open sensor, erratic code, failed element, weak igniter, or severe temperature runaway. Make one measured adjustment and evaluate several uses before changing it again.

Double ovens may store separate offsets. Convection conversion can display or apply a lower target than a conventional recipe. Confirm the selected mode and current offset before diagnosing a control fault. Preserve the original settings in notes before adjustment.

Common problems and repair decisions

Why does the GE oven temperature rise above and fall below the setting?

Ovens cycle the heat source to maintain an average temperature, so normal readings move above and below the set point. Placement, door openings, room conditions, cookware, and thermometer response affect the observed swing. Diagnose a thermostat or sensor only when cooking results and multi-cycle testing show a consistent problem.

Why does a GE oven fault code point to the temperature sensor?

The sensor may be open, shorted, or out of range, but the harness, connector, or control input can produce the same code. Disconnect power and test the complete circuit against the specified resistance chart. Inspect pin fit and heat damage before replacing the probe or electronic control.

Can a GE oven thermostat be calibrated instead of replaced?

Calibration can correct a consistent modest offset when the sensor, heating system, airflow, door seal, and controls operate normally. It cannot repair intermittent readings, damaged capillary tubing, stuck contacts, fault codes, or runaway heat. Record the original setting and make only the specified adjustment.

Why does a GE oven overheat and not turn off?

Turn off the breaker or gas supply as appropriate and stop using the appliance. A stuck thermostat, welded relay, shorted wiring, failed sensor circuit, or control fault may keep heat active. Do not rely on calibration or repeated keypad commands when the heat source fails to shut down.

Can a universal temperature sensor replace a GE oven sensor?

No. Resistance curve, probe dimensions, connector, wire rating, mounting, temperature range, and control compatibility must match. A sensor can physically mount yet report the wrong temperature. Use the complete part number and compare the specified electrical characteristics.

Installation workflow

1. Document cooking results, set temperature, selected mode, codes, cycle behavior, and existing calibration offset.
2. Disconnect power, cool the oven, and locate the thermostat, probe, limiter, connectors, and protected circuit.
3. Test the complete sensing circuit and component using the specified resistance or contact procedure.
4. Match the exact part number, electrical curve, ratings, probe or capillary geometry, connector, and mount.
5. Route sensing parts and wiring away from heat and movement without kinking capillaries or bypassing limits.
6. Restore power for attended multi-cycle checks and calibrate only if the repaired system shows a consistent offset.

Safety boundary

An oven that will not stop heating is an immediate shutdown condition. Thermostats and sensors connect to high-voltage controls and hot components. Disconnect power, never bypass a high-limit device, and do not cut or repair a capillary tube. Live diagnosis, gas-heat faults, and runaway-temperature conditions require a qualified technician.

A sensor reading can be correct while heat escapes through GE oven and range gaskets and seals. If temperature is uneven only during convection, inspect GE oven and range fans and blowers. Diagnose heat production, circulation, sensing, and control together.

Before ordering

• Confirm a repeatable temperature problem across full preheat and multiple cooking cycles.
• Match the exact thermostat, sensor, limiter, or thermal-switch part number and location.
• Compare resistance curve, contacts, ratings, probe, capillary, connector, and mounting.
• Inspect heating parts, ignition, airflow, gasket, wiring, control, and current calibration.
• Never bypass safety limits or use calibration to mask runaway heat or fault codes.
