Microwave runs for 5 seconds then shuts down displaying F9 HELP


If the microwave runs for a few seconds and stops the touchpad might be at fault. This is not common. Generally speaking, if the microwave display is working and some of the buttons respond correctly but some don't, the problem is with the touchpad

When operating microwave the displays reads "F9". what does this mean?


F9 is a failure of the door latch system, more likely the switch that tells the system it's closed. Replacement switches are inexpensive, see: http://www.electronix.com/microwave-repair-switchescouplers-c-557_564.html

I HAVE CODE F9 WHAT NEED TO FIXED COME ON BUT GO OFF AFTER 5 SEC. AND CODE F9 COME ON


A bad inverter is usually the cause of this code...try to unplug the unit and then plug it back in... if that don't work then you will need to have it checked...


The F9 code can sometimes by caused by a power surge or glitch through the electrical lines.
You can sometimes clear this fault by completely unplugging the microwave for 1 minute.
Plug it back in and see if the fault code returns.
If it does, then you have an internal component failure that will need to be serviced by a technician.
Microwaves must be serviced by technicians due to the inherent dangers involved in repairing these appliances.
Internal capacitors can retain a lethal electrical charge even though the unit is completely unplugged.
A microwave radiation leakage test must be performed on the unit following any internal component repair.

It does not ALWAYS indicate a inverter control board problem however in other brands/models.
LG's service manual (for an example) suggests the f-9 code could be due to line voltage, magnetron, inverter module, "Relay2", or a loose connection between door/magnetron/control pcb.
Other indications might help narrow down these choices before having to pull out your multimeter and crack open the microwave case.
For example, if the microwave works, but heats slowly, then the troubleshooting manual narrows your choices down to magnetron or line voltage problems, and pretty much rules out the other possibilities.

Hit the start button and runs for 6 sec then code F-9 can't find manual


You didn't mention your brand or model, but F9 code on an LG sometimes means either a bad door switch or a loose door switch mount.

See this file on door switches.

If a switch is all you need, we offer a universal type for only $5 postpaid which you can order here.

Here is more info on F9 as it relates to some brands and models:

Sears Kenmore Whierlpool LG 721.63683300

"F-9 on this microwave IS inverter related. There is a service tech troubleshooting document stuffed in behind the control board cover which has some testing proceedures. My problem was the magnatron and checked out bad with the help of this document. It would run for a few seconds making clicks and then say F-9. It has been working great since I replaced the magnatron PN 6324w1a002c."

"f9 model 721.63764300
Kenmore Elite 36 " over tne counter microwave is supplied by LG made by Gold Star, made in China. It's main problem is the high voltage inverter board supplyed by Sears Parts. If you get a F-9 code on your microwave display screen and the micro quits it's probably this board. Reset the machine by pulling the power plug and waiting an hour. If it is the high voltage board is at fault it will probably fail after 45 seconds of start up. This part is really hard to get at but is less than $100. A qualified technician should be able to remove and repair this item in less than hour. Some techs will quote you $300 labor, don't buy it, it should cost a $100 or less. No need to buy another microwave.

Humming sound, F9 and dead


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.

F9 is an error that indicates an inverter board or magnetron
has failed. With the F9 error cleared, start the oven and
listen for a ticking sound. The inverter will attempt to
'fire' the magnetron 5 times.(ticking sound). If can hear
ticking, replace magnetron. Check owners manual. Part may be covered by limited warranty.
