What F2/F20 means on your Kenmore range (kenmore f2 f20 error)
A kenmore f2 f20 error is a verified code, taken directly from GE Appliances’ own official support pages, meaning the oven temperature exceeded a preset safety threshold on your GE-built Kenmore range or wall oven (362/363/464-prefix). This is a safety-relevant overheating problem; the oven should not be used until it is diagnosed.

Symptoms
The signs below help confirm you are dealing with this condition rather than a different problem on your Kenmore range. You may notice one of them or several together, and they can appear gradually or suddenly after a power event, a wash or cook cycle, a spill, or recent installation or service.
- The display shows F2 or F20 and the oven shuts itself off
- The oven runs noticeably hotter than set before shutting down
- A burning smell accompanies the shutdown
- The code recurs on restart
Common causes
Several different problems can produce these symptoms. Working through the most likely causes in order separates a quick owner-level check from a problem that needs trained service and the correct Kenmore parts.
- Oven temperature sensor failure — an inaccurate reading is letting the oven overheat
- Stuck relay or oven-electronics problem — the element is not shutting off when commanded
Troubleshooting steps you can try
Work through these checks in order before calling for service. Stop wherever you are unsure, or where mains voltage, gas, a hot oven cavity, water, or a sealed component is involved, and hand the rest to a qualified technician.
- Turn off the range at the breaker and do not attempt to bake or broil until it is inspected.
- Do not attempt to open or test the relay board yourself.
- Book service for technician-level diagnosis of a runaway-temperature problem.
Parts a technician may replace
Depending on what the diagnosis shows, a technician may inspect, test, or replace the rtd oven sensor, relay board, and oven electronics. The correct part for your Kenmore range is matched from the model and serial number, and genuine OEM components are fitted through trusted parts suppliers rather than generic substitutes so performance, safety, and the appliance long working life are all protected. Confirming the failed part before ordering avoids replacing more than the problem actually requires.
When to call a technician
F2/F20 is a safety-relevant problem on this GE-built Kenmore platform that needs an experienced technician to test the sensor and relay board before the oven is used again. Because this condition is rated Critical severity, it is safest to stop using the range and arrange service promptly rather than keep retrying, and to shut off power or water at the source if anything looks, smells, or sounds unsafe.
