1Test probe resistance — should read ~1080Ω at room temperature
2OL reading confirms failed probe
3Reseat connector before replacing probe
4Replace oven temperature sensor if open circuit confirmed

Oven Temperature Sensor Short

RTD probe shorted — control board receiving incorrect temperature reading.

Urgent

Possible Causes
RTD probe failed shorted internally
Probe wiring shorted to oven cavity metal
Diagnostic Steps
1Test probe resistance — near 0Ω confirms shorted probe
2Inspect probe wiring for contact with oven cavity
3Replace oven temperature sensor — do not operate oven until repaired

Cooling Fan Fault

Cooling fan motor not operating correctly — control board or oven components overheating risk.

High Priority

Possible Causes
Cooling fan motor failed or seized
Wiring to fan motor open or shorted
Fan blade obstruction
Diagnostic Steps
1Check fan blade for debris obstruction
2Test fan motor winding continuity
3Replace cooling fan motor if continuity check fails

Door Lock Motor Fault

Door lock motor not confirming locked or unlocked position during self-clean cycle.

Medium Priority

Possible Causes
Door lock motor failed
Mechanical obstruction in lock path
Wiring to lock assembly open
Diagnostic Steps
1Check latch for physical obstruction
2Test door lock motor winding continuity
3Check wiring harness to lock assembly
4Replace lock assembly if motor confirmed failed

Control Board Memory Fault

Non-volatile memory on control board has lost calibration or program data.

High Priority

Possible Causes
Control board EEPROM memory failure
Power interruption during board programming
Diagnostic Steps
1Perform a power cycle — disconnect for 5 minutes
2If fault returns, calibration data is lost
3Replace control board if fault persists after power cycle

Key Panel Short

A key on the membrane panel is continuously activated or shorted.

Medium Priority

Possible Causes
Moisture on panel surface causing false activation
Physical damage to membrane keypad
Debris lodged under panel surface
Diagnostic Steps
1Dry panel area thoroughly with clean cloth
2Press Cancel to attempt reset
3Disconnect power 60 seconds and retry
4Replace control panel assembly if fault persists

Communication Fault

Communication error between main control board and display/keypad module.

High Priority

Possible Causes
Wiring harness loose between boards
Display module failed
Main control board failed
Diagnostic Steps
1Check wiring harness connections at both ends
2Power cycle unit for 60 seconds
3Replace display module or main board as indicated by further testing

Control Board Failure

Main control board has detected an internal fault — oven will not operate normally.

High Priority

Possible Causes
Control board component failure due to age or heat
Power surge damage to board circuitry
Diagnostic Steps
1Disconnect power for 60 seconds and retry
2Inspect board for visible burn marks or damage
3Replace main control board if fault persists
