KitchenAid Microwave Combination Oven
17 fault codes documented
E0 - Product not wired correctly (F9)
This error indicates an issue with how the oven is electrically wired to the house power supply, potentially an incorrect neutral connection or phase wiring.
E1 - Stuck/shorted key (F2 Keypad)
This error indicates that one or more keys on the oven's control panel keypad are either stuck in a pressed position or have an internal electrical short, which can lead to unintended commands or prevent operations.
E3 - Meat Probe Connector Jack or Meat Probe Shorted
This error indicates an electrical issue with the meat probe or its connector. It suggests that the probe itself or the jack where it connects has an electrical short, which can prevent accurate temperature readings.
E4 - Microwave Oven Relay 4903 Error (F1)
This error indicates a problem with the microwave oven's internal relay, specifically Relay 4903. This relay is crucial for the proper operation of the microwave functions.
E8 - Lost communications with Microwave Oven Appliance Manager (F6)
This error indicates that the oven's User Interface (UI) is unable to communicate with the Microwave Oven Appliance Manager. This lack of communication prevents proper control and operation of the microwave functions.
F1 E0 — Oven user interface failure
The oven's user interface (control panel) has encountered an internal failure. This can prevent you from controlling the oven functions and settings.
F1 E5 - Microwave Oven Inverter Error
This error code indicates a problem with the microwave oven's inverter system. The inverter is a key component for microwave heating, so this error means the oven may not be able to cook food.
F3 E0 — Main oven temperature sensor error
The oven's main temperature sensor is either disconnected (open) or faulty (shorted). This prevents the oven from accurately reading and controlling the internal temperature.
F4 E2 — Magnetron Temperature Sensor Error
The KitchenAid Microwave Combination Oven has detected an issue with the magnetron temperature sensor. This sensor is crucial for monitoring the temperature of the magnetron, which generates microwaves. An error here means it's not reporting correctly.
F4 E4 — Microwave Oven Humidity Sensor Error
The oven has detected a problem with the microwave oven humidity sensor. This sensor helps the oven monitor moisture levels, especially during functions like steam cycles.
F4 E8 — Inverter Over Temperature
The oven's inverter, a component vital for microwave power output, has reported an overheating condition. This often indicates an issue with the oven's cooling system.
F4 E9 — Inverter and Magnetron Over Temperature
Both the inverter and the magnetron, key components for microwave operation, have reported overheating. This strongly suggests a problem with the oven's cooling system.
F6 E0 or F6 E6 — Oven user interface or appliance manager lost communication
The oven's control panel (user interface) or the main appliance manager is unable to communicate properly. This internal communication problem can prevent the oven from operating correctly.
F6 E4 — User Interface/Appliance Manager communication mismatch
There is a disagreement or communication problem between the oven's user interface and its main appliance manager. This can lead to incorrect operation or status display.
F6 EA — User interface over temperature
The oven's user interface (control panel) has detected that it is too hot. This indicates a potential problem with the cooling system that prevents the control panel from overheating.
F8 E0 — Product not wired correctly
The oven has detected an issue with its internal wiring or power supply, suggesting it might not be correctly connected. This critical error prevents the oven from functioning properly.
F8 E1/E2/E3 — Cooling fan speed error
The oven's cooling fan is not operating at the correct speed, indicating either it's running too fast (overspeed) or too slow (underspeed). This can cause the oven to stop functioning to prevent overheating.
