Frigidaire Oven Error Code F3 in Middleburg

What error F3 means

Frigidaire's control reads the cavity sensor continuously — about 1,100 ohms at room temperature on a healthy probe. F3 sets when that circuit reads open: the sensor element failed, its wire broke, or a connector let go. It is the electrical twin of a cut phone line — the conversation with the oven's temperature simply stops.

Middleburg sits about 23 miles from Downtown Jacksonville, part of the wider metro — pros based across the city cover it on their regular rounds.

How urgent is it? Within the week. Like most sensor codes, F3 is a refusal to bake, not a hazard in progress.

What you can safely check yourself

• Expect a reset to change nothing — open circuits don't heal. One try for the record, then book it.
• Pattern notes help: F3 at the instant you press Bake means the circuit is open cold; F3 twenty minutes into a bake means something separates as it heats — usually a connector or a cracked wire.
• If the range was recently slid out for cleaning or floor work, the sensor plug at the back is suspect number one — mention it.
• The surface burners remain independent on most models; the oven is the grounded section.

What a technician checks

The sensor is metered cold, then the full run — sensor, plug, harness, board pins — is continuity-tested segment by segment, including a heat-and-wiggle pass for the intermittent opens. The failed segment is the repair; nothing else gets replaced on suspicion.

Parts most often involved: oven temperature sensors, sensor harnesses and electronic oven controls. Each is identified against your exact model number.

How it works: call the number on this page and describe what’s wrong. A local appliance repair professional who covers your area answers, runs the appliance, tests the systems the symptom points to, identifies the failed part by model number, and quotes one total for the complete repair — before starting. You decide with the full price in front of you.
