Step 01
Signs
• Oven will not heat or maintains incorrect temperature
• Error code F3 displays on the control panel
• Bake and broil functions are disabled
• Range beeps continuously or repeatedly
• Unable to start or complete cooking cycles
• Temperature display may show erratic readings or be blank
Step 02
Possible Causes
• Damaged or faulty oven temperature sensor (RTD probe)
• Loose or corroded wiring connections at the sensor or control board terminals
• Failed oven control board or electronic control unit
• Broken sensor wire inside the oven cavity
• Poor electrical connection due to 240V supply issues at the wall outlet
• Buildup of residue or debris on the sensor probe affecting readings
• Tripped circuit breaker reducing power to the range's control circuits
Step 03
Safety Checks You Can Do
• Verify that the circuit breaker for the range is in the ON position; if tripped, switch OFF then back ON to reset
• Inspect the oven interior for any visible food debris, spills, or obstructions around the sensor area and carefully remove if present
• Ensure the oven door closes completely and latches properly without gaps
• Check that all control panel buttons are functioning and no buttons are stuck or pressed
• Allow the range to cool completely for at least 30 minutes before attempting to use it again
• Perform a complete power reset by switching OFF the dedicated circuit breaker for 60 seconds, then switch back ON
• Verify the wall outlet is supplying proper 240V power and the range is securely plugged in or hardwired
• Check that the range has not been recently moved, as this may have loosened internal connections
• Clear any stored error codes by pressing the CLEAR button on the control panel after power reset
