Thermador Oven F24 Error Code: Temperature Sensor Fault

Quick Answer

F24 on a Thermador oven means the RTD temperature probe has failed or its connector has come loose. Thermador uses RTD probes, not thermistors - the resistance spec at room temperature (68 degrees F) is 1,080-1,095 ohms, rising to approximately 1,385 ohms at 212 degrees F. Start by checking the probe connector behind the oven before assuming the probe has failed - a loose connector is the cheapest fix.

Thermador uses RTD probes, not thermistors - the resistance spec at room temperature (68 degrees F) is 1,080-1,095 ohms, rising to approximately 1,385 ohms at 212 degrees F. Start by checking the probe connector behind the oven before assuming the probe has failed - a loose connector is the cheapest fix. If the probe reads OL or far outside the 1,080-1,095 ohm range, replace it. OEM part number is 00486348 and it costs $25-45. Repair success rate is 90%. F24 is the most affordable Thermador oven repair.

What Does the F24 Code Mean?

The RTD temperature probe has failed or come loose. Check the connector first, then test probe resistance (1,080-1,095 ohms at room temp). Replace if out of range.

Most Likely Causes

Based on aggregated repair data, here is the probability breakdown for this error code:

RTD probe open circuit - probe element has failed40%
Probe connector behind the oven pulled loose24%
RTD probe reading far outside expected resistance range22%
Wiring harness between probe and control board damaged14%

Symptoms You May Notice

  • F24 displayed on oven control panel
  • Oven will not enter preheat
  • Oven shuts off mid-cook with F24
  • Temperature display shows dashes or error instead of temperature

Can you reset a Thermador oven to clear the F24 code?

After replacing the probe or reseating the connector, turn off the circuit breaker for 60 seconds. Restore power - F24 should not return if the probe is now within spec. If F24 returns immediately after probe replacement, check the wiring harness and control board probe input.

Diagnostic Checklist

Follow these steps in order. We start with the easiest external fixes before opening up the machine.

1

Turn off the oven circuit breaker

Turn off the oven circuit breaker. Carefully pull the oven forward 6-12 inches to access the back panel. Locate the temperature probe connector - a small 2-wire plug at the rear of the oven. Unplug it, inspect for corrosion or bent pins, and firmly reseat it.

2

To access the probe for testing

3

Set multimeter to resistance (ohms)

4

If the probe tests good

Replacement Parts

If your diagnostic testing proves the component has failed, you will need a replacement. We recommend OEM parts over aftermarket for water-handling components.

Frequently Asked Questions

What resistance should a Thermador oven temperature probe read?
A good Thermador RTD probe reads 1,080-1,095 ohms at room temperature (68 degrees F). At 212 degrees F it reads approximately 1,385 ohms. If your probe reads OL (open circuit) or a value far outside the room-temperature range, replace it.
Does Thermador use a thermistor or an RTD probe?
Thermador ovens use RTD (Resistance Temperature Detector) probes, not NTC thermistors. RTDs have a much narrower resistance range (about 1,080 ohms at room temp) compared to the 10,000-15,000 ohm range of typical thermistors. Make sure to order the correct type when replacing.
Can I fix F24 without a multimeter?
You can try reseating the probe connector first without a multimeter - if the connector was loose, this may resolve F24 at no cost. However, if the connector is seated and F24 persists, you need a multimeter to confirm whether the probe has actually failed before spending $25-45 on a replacement part.
F24 appears only sometimes during cooking. Is the probe failing?
Intermittent F24 often means the probe is marginal - it reads within spec at room temperature but drifts out of range as it heats up, or the connector is making poor contact. Test the connector first. If that is fine, the probe is likely developing an intermittent open and should be proactively replaced.
