Microwave Error Code F9 Troubleshooting

With the full model number, we could have looked up what an F9 code means on that model.

Usually it's a failure in the inverter circuit.

Sorry to read about your problem, I hope this helps you out.

The F9 error code indicates an inverter failure. If you continue to receive the F9 error code after unplugging the unit for 5 minutes, the control system assembly may need to be replaced.

Note : Microwaves are not good do-it-yourself projects. Microwaves are inherently dangerous to service. Internal capacitors can retain a lethal electrical charge even when the microwave is unplugged. A microwave radiation leakage test must be performed on the unit following any repair.

Hi,

Many models of the GE microwave have sensors that can detect humidity from the foods you are cooking. This allows the microwave to make adjustments to the power levels used to cook your food. If "Sensor Error" appears, you should either press "Clear" to cancel the mode or leave the food in the appliance longer to give the microwave more time to detect the food.

Press "Time Cook" to manually enter the time if you receive an error message when trying to use the "Sensor Reheat" mode of your GE microwave. The error message may be caused by the food item being too large or too small to detect.

these are some other code error that will help you in case of next time.

1. Step 1 Press "Off/Cancel" (or "Cancel/Off" depending on your model) to clear the error code. Note the code if it reappears.
   
2. Step 2 Replace the touchpad if the code displayed is "F0," "F7" or "F10." A function key is stuck or shorted.
   
3. Step 3 Replace the touchpad or the clock (ERC) if the code "F1" is displayed. Disconnect the ribbon connector to the touchpad. If no code is displayed after an hour, replace the touchpad. If the code displays again, replace the clock.
   
4. Step 4 Replace the oven temperature sensor if "F2," "F3" or "F4" is displayed. "F2" indicates the oven temperature is too hot and the oven temperature sensor is suspect. "F3" or "F4" indicates the oven temperature sensor or shorted or open.
   
5. Step 5 Replace the ERC if "F5," F6" or "F8" is displayed. The ERC is the main control unit. "F5," F6" and "F8 are codes that indicate problems in the ERC functions.
   
6. Step 6 Inspect the door-lock assembly and circuit if "F9" is displayed. The door must lock when the oven is in use. If the lock mechanism is not functioning or if the detection circuit is malfunctioning, the stove will display "F9."
   

jQuery('.article ol .image').each(function(i,e){ var $this = jQuery(this); $this.find('img').error(function(){ jQuery(this).remove(); $this.remove(); }); }); NOTE:


"F3" codes mean your oven temperature sensor has failed or shorted out. The only thing you can do is to replace the sensor.

Take care.

My Kenmore Elite Microwave Model No. 721.64683300 does not seem to be heating well and will shut off and flash an F9 code. What does the F9 code mean

The F-9 error code indicates a defective control board, inverter or line voltage too high.

Repair or Replace them.


Thanks.

Seems like I answered this, but maybe it's a different poster.

The 721 model code means it's an LG/Goldstar-made oven and F9 indicates a problem with the inverter or magnetron.

Due to the lethal voltages involved, I do not recommend that a person without training and experience ever work on these models.

I would suggest you contact Sears for service.

Need to know the entire model # on the microwave.
