F-9 Error after running a few seconds...

Did anyone find out what this Error Code means. I called Sear's repair/service department, but they couldn't help.

    IF the F9 code is a door switch problem how might I remedy that? How do I change the inverter board or magnetron?

    The whole thing runs like a dream, sounds like it is supposed to sound, and kicks off after about 9 seconds and displays the F-9. (LG Microwave).

    I am very mechanically inclined and if I have a piece to replace I can do just about any of that.

    Thank you for your time and your microwave brilliance Reg!

If this is a "SmartWave" branded microwave oven then F9 is an error that indicates an inverter board or magnetron has failed. Either way.. Try this...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....Else in may be a door switch problem

Microwave keeps shutting off after a few seconds and error number H97 shows up on display pad. What does this error mean?

Error code H97 is an indication of a possible failure of the Magnetron, DPC board or the High Voltage Inverter board. It could be just a loose wire connection also between the DPC board and the High Voltage Inverter board.

This failure will require a service technician to diagnose and repair.

Error code H98


Unplug the microwave and plug it back in after 30 seconds to make sure the message did not appear because of a simple glitch. If it does not come up again, use the microwave as normal.

The "H98" error means that the microwave's inverter has shorted out and does not work any more. The microwave cannot transfer power to create heat, and the part has malfunctions and requires replacement. Use your microwave serial number and customer service to find the proper part for the microwave.

Your microwave comes with a warranty that will cover the inverter if the warranty is still valid. Call the number for the warranty department or bring the microwave, with receipt, back to the store you purchased it from. This will save you the hassle of replacing the par

Control display is flashing FS or F3 and then turns itself off

The error code F-S or F-5 is the closest error message I have found in information for your convection microwave oven. The F5 error code indicates that the damper switch has a sensing error. Be sure that the blower outlet is not blocked or restricted. I would recommend calling for service on something like this.

The F3 error code is an indication of a stuck key panel. We do not recommend that the customer remove the cover of their microwave oven. Even with the microwave oven unplugged, there are some components that hold a charge of 25.000 volts.

Note: General resolution for problem is based on information submitted with question. If problem persist, contact a service technician to Sears Repair Department 1-800-469-4663.

Hope this helps (remember to rate and comment this answer).

What does F1 mean and how can I correct it?? Anyone? Anyone?

HI. This error code is in reference to a failed control board. It may be correctable by simply unplugging for a few minutes, and re-introducing power. If the code reappear after the hard reset, this will indicate that the control board is, indeed, damaged. It must be replaced, in this case.

F-1 - Electronic control malfunction

Model 72180883400

F-9 error code indicates a defective control board, inverter or line voltage too high. f the microwave runs for about 7 seconds with a ticking sound..then stops and shows "F-9", it is the magnetron that has failed. The fact that the unit starts and runs with the TICKING SOUND means the control board is sending signal to inverter board and the inverter board is sending signal to magnetron. Magnetron is covered by full 5 year warranty, inverter board is only 3 years.

Microwave runs for only a few seconds and then an error message of H98 is displayed and quits working Microwave only used for 6 months.

H95, H97, H98 or H99 mean that there's a problem with your inverter, magnetron, or digital programming circuit.

In most cases, this is a problem with the inverter or a bad magnetron.

Due to the lethal voltages used and produced, I do not recommend that an inexperienced person work on these.

I would recommend that you contact your nearest Panasonic-authorized servicer.

Being 6 months old means it will be repaired free of charge.

The first thing to try is a "hard reset". Unplug it from the power line for a few minutes, plug it back in, set the clock, then try again.

Otherwise, your best bet is to contact AEG customer service here:

I'd bet that customer service will not know the meaning of the code (if it's not in your owner's manual) and they will steer you to a service center.

The service center will probably not tell you what the code means, preferring instead to repair it for you.

Good luck.

Kenmore microwave model 66569619992

The first three digits of your model number are 665, which means it was made by Whirlpool.

On a Whirlpool, F6 means a fault on the control board, such as a timing error or a shorted relay.

A shorted relay could mean it is running when it shouldn't. Pleased don't allow it to do that for more than a few seconds, or other serious damage could occur.

The first thing to try is a "hard reset". Unplug it from the power line for a few minutes, plug it back in, set the clock, then try again.

If it still fails, please leave it unplugged, and I would say you have a problem on your control panel assembly, which we repair for customers nationwide with our $39.95 service.

Please feel free to contact me directly if you need more help.
