How to Fix Error F21
DIY Fix Check for obvious issues and power cycle
- Turn off the oven and disconnect power at the circuit breaker.
- Visually inspect the upper heating/grill element for signs of visible damage (cracks, burns).
- Restore power and see if the error reappears after a simple reset.
Technician Only Test and replace heating element or related components
- Disconnect power and remove oven access panel to reach the upper heating element.
- Use a multimeter to check continuity and correct resistance of the grill/upper heating element.
- Inspect and test wiring harness and connectors for continuity and secure connections.
- Replace the heating element if open circuit or out of spec.
- If element tests OK, test control board outputs to the element; replace faulty control electronics if needed.
Parts needed: Upper/grill heating element, Wiring harness/connectors, Possibly control board
- If the error persists after visual checks and power cycling
- If you cannot safely access or test internal components
- If multimeter diagnostics show wiring or control issues rather than a simple element failure
