Temperature sensor is not working

Whirlpool codesWhirlpool cooktop codes

Temperature sensor is not working - Type 1 failure affecting only one burner.

First step from the service manual

Disconnect power and check that the temperature sensor (SI) is between 184k ohms and 292k ohms at room temperature and is firmly plugged in.

What F-36 means on a Whirlpool cooktop

The F-36 error code on a Whirlpool cooktop indicates a Type 1 temperature sensor failure affecting a single burner zone. The temperature sensor, referred to in diagnostics as the SI sensor, is a thermistor-based component that continuously monitors the surface temperature of an individual induction or radiant burner element. The control board uses resistance readings from this sensor to regulate heat output and prevent overheating. When the board detects that the sensor signal is outside the expected parameters, it triggers the F-36 fault and disables that burner to prevent unsafe operation.

The primary diagnostic check involves disconnecting power to the unit and measuring the resistance across the affected temperature sensor. At room temperature, a properly functioning SI sensor should read between 184k ohms and 292k ohms. Readings outside this range indicate the sensor has failed and needs replacement. A loose or intermittent connector can also cause the fault without the sensor itself being defective, so confirming the connector is firmly seated is part of the initial inspection.

Because only one burner is affected, the failure is isolated to that specific sensor circuit rather than a shared control board input. This makes component-level diagnosis more straightforward. Common contributing factors include heat stress over time that shifts the thermistor out of its calibrated resistance range, physical damage to the sensor or its wiring harness, and connector corrosion or loosening from vibration and thermal cycling.

Common causes of F-36

  1. 01

    Failed temperature sensor (SI thermistor)

    Part replacement

    The thermistor inside the SI sensor drifts out of its acceptable resistance range of 184k to 292k ohms due to heat stress or age. Measuring the sensor with a multimeter at room temperature will confirm whether the reading falls outside this window.

  2. 02

    Loose or disconnected sensor connector

    Wiring / connection

    The sensor connector may have worked loose from its socket on the control board or sensor harness due to vibration or thermal expansion and contraction. Disconnecting power and firmly reseating the connector is part of the first diagnostic step.

  3. 03

    Damaged sensor wiring harness

    Part replacement

    The wiring between the SI sensor and the control board can develop breaks, shorts, or chafing, particularly near areas exposed to heat or sharp edges. Visually inspecting the harness for burn marks, fraying, or pinched sections will help identify this issue.

  4. 04

    Corroded sensor connector pins

    Wiring / connection

    Moisture or grease contamination on the connector pins can increase resistance and disrupt the signal to the control board. Inspect the connector for discoloration, oxidation, or residue that could affect continuity.

  5. 05

    Faulty control board

    Part replacement

    If the sensor and wiring both test within specification, the control board input circuit that reads the sensor signal may have failed. This is the least likely cause and should only be considered after the sensor and harness have been ruled out.

Frequently asked questions about F-36

What does F-36 mean on a Whirlpool cooktop?
F-36 indicates a Type 1 temperature sensor failure affecting a single burner. The cooktop's control board has detected that the SI temperature sensor on one burner zone is not providing a signal within the expected parameters. The affected burner is disabled as a safety measure, while the remaining burners continue to function normally.
Can I fix the F-36 error myself?
A knowledgeable DIYer can attempt the initial diagnostic steps. Start by disconnecting power and checking whether the SI sensor connector is firmly seated. If you have a multimeter, measure the sensor resistance at room temperature and confirm it falls between 184k ohms and 292k ohms. If the sensor is out of range, replacing it is a straightforward repair, though accessing it will require disassembling part of the cooktop.
Is it safe to keep using my cooktop with an F-36 error?
The burner associated with the F-36 fault will be disabled, so that specific zone cannot be used until the sensor issue is resolved. The remaining burners should operate normally. It is best to address the fault promptly rather than continuing to use the unit long-term with a disabled safety sensor.
Will resetting the cooktop clear the F-36 error?
Disconnecting power and restoring it may temporarily clear the fault display, but if the underlying sensor problem has not been fixed, the F-36 code will return once the cooktop attempts to use the affected burner. A reset is not a repair and should only be used as part of the diagnostic process.
How much does it cost to repair an F-36 error on a Whirlpool cooktop?
If only the SI temperature sensor needs replacement, parts typically range from around $20 to $60 depending on the specific cooktop model. Adding professional labor, the total repair cost generally falls between $100 and $250. If the control board is at fault instead, costs can be higher, typically ranging from $200 to $400 or more for parts and labor combined.
