F30 error code, oven temperature reading erratic or oven will not heat properly.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Out-of-range oven temperature sensor, Poor sensor connection at control, Faulty control board temperature circuit

Safety: Turn off power before testing.

Sensor test: Remove and test the oven sensor as described for F3/F4. Compare resistance to GE sensor chart (approx. 1080 Ω at 70°F, 1650 Ω at 350°F).
Connector check: Inspect the sensor connector at the control board for tight fit and no corrosion.
Replace sensor: If readings are out of spec, install a new GE-compatible RTD sensor.
Control board: If a known-good sensor still triggers F30, replace the EOC.
