Frigidaire Oven: error code F30
What is this symptom?
If your Frigidaire oven displays the F30 error code, it indicates an issue with the oven temperature sensor circuit. This can result in the oven failing to heat properly or shutting down unexpectedly. Common causes include a faulty temperature sensor, damaged wiring, or issues with the control board. Understanding these symptoms can help you diagnose and resolve the issue effectively.
Important Tips for Frigidaire Models
- Frigidaire specifically codes F30 as ‘Open Probe’ indicating an open circuit in the oven temperature sensor.
- Some Frigidaire models display F30 when the oven control board misreads sensor resistance even if sensor is OK; board replacement may be required.
Possible Causes
Faulty oven temperature sensor (RTD/thermistor)
How to Identify: Oven shows F30 code; testing sensor resistance with a multimeter at room temperature yields out‑of‑range values.
Part: Oven temperature sensor probe
Broken or damaged sensor wiring or loose connector
How to Identify: Sensor tests good, but continuity from connector to control board fails or wiring shows visible wear, fray, or loose connections.
Part: Sensor wiring harness and connectors
Electronic Oven Control (control board) misinterpreting sensor signal or defective
How to Identify: Sensor and wiring test within specification, but F30 persists; control board shows signs of damage or fails to register correct resistance.
Part: Electronic Oven Control board
DIY Solutions
Reset oven power
- Turn off power at wall outlet or circuit breaker for ~30 seconds.
- Restore power and check if F30 code clears.
Test and replace oven temperature sensor
- Turn off power at circuit breaker.
- Remove oven racks and access rear of oven cavity to locate temperature sensor.
- Disconnect sensor and measure resistance at room temperature; compare to ~1000–1100 Ω spec.
- If out of range, install replacement sensor and reassemble.
- Restore power and verify error cleared.
Check and repair wiring harness connections
- Power off at circuit breaker.
- Inspect wiring from sensor to control board for breaks, corrosion, or loose gauges.
- Test continuity through wiring; repair or replace damaged sections.
- Secure connectors at both sensor and control board ends.
- Restore power and test oven function.

User Suggested Solutions
-
Inspect and replace the temperature sensor. Disconnect the oven from power, locate the temperature sensor (usually at the back of the oven), and check for continuity with a multimeter. If faulty, replace it with a new one.
-
Check the wiring harness for damage. Open the oven's back panel, visually inspect the wiring for any signs of wear or disconnection. Repair or replace any damaged wires.
-
Test and replace the control board if necessary. Access the control board by removing the front panel. Inspect for burnt components or loose connections. If the board is defective, replace it with a compatible part.
