What F30/F31 means on your Kenmore range (kenmore f30 f31 error)
A kenmore f30 f31 error is a verified code, confirmed by Frigidaire/Electrolux repair references, meaning the RTD probe/sensor is disconnected or open-circuit (F30, older two-digit F3) or shorted (F31, older two-digit F4) on your Frigidaire/Electrolux-built Kenmore range or oven (119/253/336/417/587/622/628/719/790/791/970-prefix). Ranges manufactured before roughly 2004 use the legacy two-digit codes; those built afterward show the expanded three-digit versions.

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 F30, F31, or the legacy F3/F4
- The oven will not heat, or heats inconsistently
- The oven shuts off mid-bake
- The code returns on repeated bake attempts
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.
- RTD probe open circuit (F30/F3) — the sensor has failed or disconnected
- RTD probe short circuit (F31/F4) — the sensor or wiring has shorted
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.
- Power the range off at the breaker for a few minutes to force a reset.
- Visually check the oven sensor probe for damage, without touching a hot oven.
- Confirm the sensor wiring connection is seated at the back of the cavity, if accessible.
- If F30/F31 returns, book service for sensor replacement.
Parts a technician may replace
Depending on what the diagnosis shows, a technician may inspect, test, or replace the rtd oven probe and sensor wiring. 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.
