What Does Error F3 Mean?

The Haier oven F3 error code signifies a malfunction in the temperature sensor, leading to inaccurate temperature readings or the oven's failure to heat properly. This issue often arises from a faulty temperature sensor or wiring problems affecting the sensor's connection to the control board. The oven may stop heating or display the F3 error upon starting a cooking cycle, and it may beep or shut down to avoid unsafe conditions.

Common Symptoms:

  • Oven stops heating or displays F3 upon starting a cooking cycle
  • Inaccurate temperature readings or failure to reach set temperature
  • Possible beeping or immediate shutdown to prevent unsafe conditions

Possible Causes

  • Faulty temperature sensor (RTD) (medium)
  • Wiring harness/connectors to the temperature sensor are loose, damaged, or corroded (medium)

How to Fix Error F3

DIY Fix Power cycle and basic check

  1. Turn off the oven and disconnect power (unplug or switch off at breaker).
  2. Wait a few minutes and restore power to see if the error clears.
  3. Ensure the oven cavity is cool and inspect the temperature sensor visually for obvious damage if accessible.

Technician Only Diagnose and repair sensor circuit

  1. With power off, access the oven’s internal temperature sensor (RTD) and wiring harness.
  2. Use a multimeter to measure the sensor’s resistance at room temperature; compare against specification.
  3. Check for continuity in wiring and secure all connectors.
  4. Replace the temperature sensor if resistance is out of range or open.
  5. If sensor and wiring are good but F3 persists, test control board input and replace control board if required.

Parts needed: Temperature sensor (RTD), Wiring harness/connectors, Oven control board

🛑 When to Call a Pro:
  • If you are not comfortable working with appliance electrical components
  • If multimeter testing and basic inspection do not resolve the issue
  • If control board replacement is indicated but beyond DIY capability
