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
- Turn off the oven and disconnect power (unplug or switch off at breaker).
- Wait a few minutes and restore power to see if the error clears.
- Ensure the oven cavity is cool and inspect the temperature sensor visually for obvious damage if accessible.
Technician Only Diagnose and repair sensor circuit
- With power off, access the oven’s internal temperature sensor (RTD) and wiring harness.
- Use a multimeter to measure the sensor’s resistance at room temperature; compare against specification.
- Check for continuity in wiring and secure all connectors.
- Replace the temperature sensor if resistance is out of range or open.
- 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
- 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
