What Does Error F04 Mean?

The Maytag dryer F04 error code indicates a malfunction in the thermistor or temperature sensor, leading to improper heating or inconsistent temperature readings. Symptoms include the dryer stopping mid-cycle, failing to heat, or the drum not turning. It's essential to address these issues promptly to ensure your dryer operates efficiently.

Common Symptoms:

  • Dryer stops mid‑cycle with F04 displayed
  • Dryer may fail to heat properly
  • Dryer may not start or drum may not turn

Possible Causes

  • Temperature sensor / thermistor fault (medium)
  • Inadequate power supply / line voltage issue (medium)

How to Fix Error F04

DIY Fix Basic checks before repair

  1. Unplug the dryer from power and wait a few minutes, then reconnect to reset electronics.
  2. Ensure the vent and lint filter are clean to avoid related issues.
  3. Verify that the circuit breaker(s) for the dryer are not tripped and that the outlet is supplying correct voltage (240 V for electric dryers).

Technician Only Inspect and test thermistor / power supply

  1. Disconnect power and access the temperature sensor/thermistor assembly.
  2. Measure the thermistor’s resistance with a multimeter across temperatures to confirm proper behavior.
  3. Check wiring harnesses for damage or loose connections.
  4. Measure actual line voltage at the dryer’s power terminals to confirm adequate supply.
  5. Replace the thermistor or address voltage wiring issues as required.

Parts needed: Thermistor / temperature sensor, Wiring harness, Potential power cord or terminal block parts

🛑 When to Call a Pro:
  • If line voltage cannot be verified safely
  • If thermistor testing yields inconclusive results
  • If replacing sensors does not clear the code
