Microwave Fault Codes
Failure Code Condition Check/Repair
F1 Open sensor.
1. Will occur below 190F of cavity temperature within 15 minutes after starting convection, combination or roast cook.
2. Check oven temperature sensor for continuity. Replace if zero or infinite ohms.
F2 Shorted thermal sensor.
1. Will occur if a shorted thermal sensor is detected continuously over 5 seconds on convection, combination or roast cooking.
2. Check oven temperature sensor for continuity. Replace if zero or infinite ohms.
Note: It will take a minimum of 5 minutes of convection run time before F1 or F2 code will be displayed if the thermal sensor is shorted or open.
F3 Shorted key panel (touch pad).
1. Will occur if a shorted key panel is detected continuously over 60 seconds.
2. Replace key panel (touch pad).
F4 Open humidity sensor.
1. Will occur if humidity sensor is detected as being open continuously over 5 seconds.
2. Replace humidity sensor.
F5 Shorted humidity sensor.
1. Will occur if humidity sensor is detected as being shorted continuously over 5 seconds.
2. Replace humidity sensor.
F6 Shorted temperature probe.
1. Will occur if temperature probe is detected as shorted continuously over 5 seconds.
2. Replace temperature probe.
ProbEe Open temperature probe.
1. Will occur if temperature probe is detected open.
2. Or not plugged into the receptacle.
3. If probe is plugged in and "ProbE" is on display check continuity of the probe with an ohm meter.
4. If zero or infinite ohms, replace it.
