Maytag F22 / F23: Exhaust thermistor (temperature sensor) failure

On older Bravos/Cabrio-platform Maytag dryers, F22 and F23 both flag a failed exhaust thermistor - the sensor that tells the control the drum temperature. The dryer cannot regulate heat until the sensor or its wiring is fixed.

Most likely causes

  1. Failed or out-of-range exhaust thermistor
  2. Broken, loose, or corroded wiring at the thermistor connector
  3. Harness damage between the sensor and control board
  4. Faulty main control board reading the sensor

Schematic illustration of a typical dryer — not your exact model.

Before you start — unplug the dryer, and on a gas model shut off the gas supply. Let it cool first — the drum, heater and exhaust can be hot. If a step involves the heating element, wiring, or opening the cabinet and you're unsure, stop and call a qualified technician.

Step-by-step fix

1Try a resetUnplug the dryer or switch off the breaker for about 10 minutes, then restore power and retest.
2Unplug for safetyIf the code returns, disconnect power before opening the cabinet.
3Inspect the connectorFind the exhaust thermistor at the blower housing and check its wires and plug for looseness or corrosion.
4Test the sensorMeasure the thermistor's resistance with a multimeter and compare it to the service spec for room temperature.
5Replace the thermistorReplace the sensor if it is open, shorted, or out of range; if it tests good, have the control board checked.

Still showing F22 / F23?

If you’ve worked through every step and F22 / F23 keeps returning, an internal part likely needs testing and replacement. That’s a job for a qualified appliance technician, who can measure the suspect part against the service-manual spec before replacing it.

Which models this applies to

Maytag dryers. Older Maytag Bravos and Cabrio-platform dryers using F## fault codes; newer models show a thermistor fault as E1/E2 or F3-series instead.
