What Does Error F23 Mean?

The Maytag dryer error code F23 signifies a communication failure between the control board and the user interface, often leading to an unresponsive or flickering display. This error is commonly associated with issues in the exhaust thermistor or temperature sensor, which can disrupt the dryer’s heating functionality due to improper temperature monitoring. Immediate attention is recommended to diagnose and resolve the underlying cause.

Common Symptoms:

  • Dryer displays F23 error on control panel at start or during cycle.
  • Dryer may not heat properly due to temperature monitoring issues (community reports).

Possible Causes

  • Exhaust thermistor / temperature sensor failure or fault (medium)

How to Fix Error F23

DIY Fix Power Reset and Monitor

  1. Locate the household circuit breaker for the dryer and switch it off.
  2. Leave off for at least 5 minutes to let the dryer reset internal controls.
  3. Turn the circuit breaker back on and start a timed dry cycle.
  4. Observe whether the F23 code reappears within the first minute.

Technician Only Test and Replace Exhaust Thermistor / Temperature Sensor

  1. Disconnect power to the dryer.
  2. Access the exhaust thermistor / temperature sensor according to model-specific service manual.
  3. Measure resistance at room temperature with a multimeter; compare to manufacturer specification.
  4. If resistance is out of spec or sensor shows open/short, replace with correct thermistor for model.
  5. Reassemble and power on; verify error code no longer appears.

Parts needed: Exhaust thermistor / temperature sensor

🛑 When to Call a Pro:
  • If diagnostic testing (resistance checking) is inconclusive or if error persists after sensor replacement.
  • If internal wiring harness shows damage or sensor is inaccessible without major disassembly.
  • If dryer exhibits additional error codes or symptoms beyond F23.
