## How to Fix Maytag Error F24 (Temperature Sensor)
—
### Explanation: What F24 Means
The F24 error code on your Maytag washing machine (typically models featuring a temperature sensor) indicates a failure in the **Water Temperature Sensing Circuit**.
In plain English, the Central Control Unit (CCU) is not receiving a reliable signal from the **thermistor** (the dedicated temperature sensor) or is receiving a signal that is outside of the acceptable range.
The washer stops the cycle because it cannot safely regulate water temperature, posing a risk of overheating or damage to delicate clothes. The problem is almost always caused by a faulty thermistor, but occasionally involves damaged wiring or a failed main control board.

### Step-by-Step Fix: How to Diagnose the Thermistor
Before attempting any repair, **unplug the washing machine from the wall outlet.** Failure to do so can result in severe electrical shock.
#### 1. Locate the Thermistor
The water temperature thermistor is typically mounted directly onto the heater element or located in the tub sump area, often accessible by removing the back panel of the washing machine.
* **Access:** Depending on your model, you may need to remove the main back access panel or the lower front kickplate to gain visibility.
* **Identification:** The thermistor is a small, usually black component connected by two wires (often located next to the heating element).
#### 2. Visual Inspection and Wiring Check
Once you locate the thermistor:
* **Check Connections:** Look for any frayed, scorched, or disconnected wires leading into the sensor. If the wiring harness looks damaged, replace the harness.
* **Check for Corrosion:** If water has leaked onto the sensor connection points, clean any visible corrosion.
#### 3. Test the Thermistor Resistance (Multimeter Required)
The most definitive way to diagnose the F24 error is to test the electrical resistance of the thermistor using a multimeter set to the Ohms ($Omega$) setting.
1. **Disconnect:** Pull the two wires off the thermistor terminals.
2. **Measure:** Place the probes of the multimeter directly onto the two thermistor terminals.
3. **Read:** Compare the reading to the expected resistance range. Thermistors are sensitive to temperature, but at standard room temperature (around 70°F / 21°C), they usually register between **10,000 to 15,000 Ohms (10K to 15K Ohms)**.
| Condition of Thermistor | Expected Multimeter Reading | Diagnosis |
| :— | :— | :— |
| **Normal** | 10K to 15K Ohms (at room temperature) | The thermistor is likely fine; check wiring harness or CCU. |
| **Open Circuit** | Infinite resistance (O.L. or “1” on the meter) | **Thermistor is faulty.** Replace the part. |
| **Short Circuit** | 0 Ohms or very low resistance | **Thermistor is faulty.** Replace the part. |
#### 4. Replace the Thermistor
If your multimeter reading indicates an open or short circuit, the thermistor must be replaced.
* **Removal:** The thermistor is usually held in place by a clip or simply snaps into the housing. Remove the old unit.
* **Installation:** Insert the new thermistor, ensuring it seats securely and reconnect the wiring harness.
* **Reassemble:** Put the access panels back on, plug the washer in, and run a diagnostic or quick wash cycle to clear the F24 error.
