SOURCE: kenmore microwave model number 401.80084700 Displaying -SE-/-5E-

-SE- error means you have a shorted membrane keypad.

So until it is repaired, please leave it unplugged or leave the door open when it's not in use, and of course one should never leave a microwave unattended while cooking.

There are three ways you can get it fixed:

DE34-00178X SWITCH MEMBRANE $20.30
ref#53 membrane keypad
take yours off as in the video at our site, peel the old keypad off as in this handy guide with pictures , clean the surface, stick on the new keypad
order by part number here
(We can do this job for you for a total of $70.25, but as you can see, the other two options are more practical and economical)

DE94-01647A ASY CONTROL PANEL $39.01
ref#66 control panel frame with keypad
take yours off as in the video at our site, disconnect the keypad strip as shown here, move your circuit board to the new frame, reinstall
order by part number here

DE94-01648A ASY CONTROL, BOX $58.12
ref#59 complete control panel assembly with frame, keypad and circuit board
take yours off as in the video at our site, then install the new one
order by part number here

If these parts are not in stock, they should be available in about a week or so.

We're happy to help you with free advice and we'd appreciate your thoughtful rating of our answer.

SOURCE: wjusino just asked: My kenmore microwave doesnt heat.

In all likelihood the mangnetron has failed, or perhaps even the Power Supply. or a fault that is shutting the system down for safety reasons You need to have it serviced by a reputable service centre/man.
Ensure you get a firm "Quote" before proceeding, and remember these days the cost of repair can equal or exceed the price of a new one.

Our microwave stops after a few seconds and code comes up F9


It of course depends on the model number, but here's some discussion from other boards:

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.

To find helpful exploded view diagrams and get part numbers, you can just enter your full model number at the Sears parts site.

But Sears parts can usually be obtained for far less here by entering either the part number.

A full Sears/Kenmore model number has 3 digits, a dot, then 8 more digits, such as ###.########.

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:

Microwave has an error code F9 after running for about 5 seconds


Some quotes from other forums, but note that you need to look up your model to verify part numbers:

"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.

There should be a "mini-manual" hidden inside the unit behind the control panel or hidden behind the grille, which is very helpful when troubleshooting, & testing.

To find helpful exploded view diagrams and get part numbers, you can just enter your full model number at the Sears parts site.

A full Sears/Kenmore model number has 3 digits, a dot, then 8 more digits, such as ###.########.

BUT once you have the part number from the Sears site, you can often get the parts cheaper

UNIT POWERS OFF AND DISPLAYS "F-9"


an inverter failure. This 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

Shuts down after running about 8-9 seconds.


We'd need the full model number to be sure, but it sounds like an inverter failure. Due to the lethal voltages involved, I do not recommend that a person without training and experience ever work on these models. I would call Sears for service. See http://www.sears.com
