I am having the same problem. According to the owner's repair guide error Code F7 indicates that power to the magnetron was interrupted. You will want to make the following checks: 1. Unplug microwave oven or disconnect power. 2. After 40 seconds, check to see whether this solves the problem. 3. Unplug microwave oven or disconnect power. 4. Check resistance of the magnetron thermostat. 5. Check the magnetron. 6. Check wiring to the 1100W inverter and control system. See "Checking Inverters." 7. Plug in microwave oven or reconnect power. 8. Check operation of all interlock switches. Check door, hinge and cavity front alignment. Adjust as needed. 9. Unplug microwave oven or disconnect power. 10. If switches operate correctly, replace 1100W inverter. 11. If problem persists, replace electronic control. 12. Plug in microwave oven or reconnect power. While this is helpful, it is still out of my confort zone as I pulled the control panel and discovered a virtual zoo of connectors. Obviously ponly a trained repairman knows which ones need to be checked. I will probably have to resort to calling one and shelling out the dough.

This sounds like the magnetron has failed, the pop sound is a classic sysmptom.

Hello & Welcome to FixYa

The problem is with the fuse or the high voltage transformer that is bad and needs replacement. Replacing the fuse will cost you under $100 from a professional and getting the transformer replaced will cost you around $200. As the unit has very high voltage inside so we don't recommend that this should be done by the user. Please get back to me if you have any other questions.

We see (and repair) this a lot. The problem is on the control panel, which we regularly repair nationwide by mail for $39.95 with a one-year repair guarantee.

At our Web site, you can get details of our service, plus we have a video available showing how to remove a typical over the range control panel assembly in under 5 minutes.

Also consider "CU-LCD" listed here.

Check this image for your Microwave parts, part#25 and part#29 are two thermal fuse. If both of them are fine then it is the electronic control that is bad and needs replacement. Please get back to me if you have any other questions.

Hi,

In your owner's manual (available free online here) this is called the "microwave inlet cover".

See the tag in your oven cooking cavity or near the door frame for your full model number.

The cover is located in the ceiling of the oven.

You should be able to remove and clean or replace the cover without removing the oven from the wall.

The oven installation instructions and parts list are also on that page.

You can also find handy exploded views and order any needed parts and accessories by model or part number here.

I would think that the touch pad will need replacing.

If you were to log on to the manufacturer's web site, I think you will be pleasantly surprised as usually one is able to download, by model number, Customer Instruction Manuals, list of Dealers for spare part supplies and Driver downloads as required.

Just Google the manufacturer's name and follow the links. Make certain you are directed to the manufacturer's web site as some search engines direct you to other sites and they charge for the information that is normally free of charge.

I hope this helps.

Sounds like the magnetron shorted out. This is the part that heats the food. Unfortunately, this part is almost more cost than a new microwave so I would recommend just getting a new microwave. If you would rather try replacing this part, you can order a new one from repairclinic.com and find one by searching with your model number. Let me know if you need anything else.

Microwave Oven Basic Troubleshooting Tips

The first thing I would suggest is a hard reset. Unplug the unit for a minute or so. Then plug it back in, set the clock and try again.

If that doesn't work, leave it unplugged for about 5 minutes.

Otherwise, you probably have a failed membrane keypad.

Is it possible that some spray cleaner or steam accidentally got into the controls?

Direct spraying of cleaners on the keypad and steam from the cooktop can damage the controls.

I always recommend that you spray non-ammonia cleaner on a soft cloth (not a paper towel which can scratch) and gently wipe the keypad.

And I always recommend that you use the vent fan whenever you're cooking on the stove top to keep heat, steam, and grease out of the controls and door panels.

If it does not dry out over time, it may need to be manually dried or blown out.

The keypad may be damaged or worn out, or control unit may be damaged.

If you (or someone you know) might want to replace it yourself, I have uploaded a handy guide with pictures showing you what's typically involved.

There should be a "mini-manual" (tech sheet) hidden inside the unit behind the control panel or hidden behind the grille, which is very helpful when troubleshooting, testing, and locating components.
At our Web site, we have a video available showing how to remove a typical over the range control panel assembly in under 5 minutes.

But please note that for some models, the membrane keypad is not
available as a separate part, so you would have to order the control
panel frame assembly which comes with a new keypad.

In this case, you simply move your circuit board into the new frame. That is a simple do-it-yourself
job.

I recommend that you bookmark that link to your favorites.Feel free to contact me directly (and please remind me of your full model number from the tag on the unit) for more information & help.
