Kenmore Sensor Open Circuit Detected

F4 error appears and cooker refuses to start any program.

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

Broken NTC sensor lead, Unplugged sensor connector, Cracked sensor body

Safety first: Unplug the unit before opening the base.

Check connector: Access the bottom of the cooker and verify the sensor connector is firmly attached to the main PCB.
Inspect sensor leads: Look for broken or detached wires at the sensor mounted on the heating plate.
Test continuity (advanced): Use a multimeter to check continuity across the sensor leads. An open reading indicates a failed sensor.

Replace the NTC sensor if open, and re-test the unit.
