Hi, you have a faulty magnetron, capacitor, or diode that's keeping the unit from heating anything. They have internal fuses, but its good or nothing wood work. You can have these parts checked out at a appliance repair store, but wit parts and labor it may cost more then a new one just to be truthful with you. If you are handy, you can get into the electrical section and may get luck and see which part is faulty just by looking at them, for any blackish, scorching on any circuit boards, a capacitor is a small round or oval shaped part that holds a charge and these sometimes will leak, swell up and crack causing them to fail. If you want, you can try this. If you do have a board, this is where any diodes would be on the face of it, remove it enough to look on the back side for scorching and you can take it and purchase a new one and be back on line. These are just some options you may want to try. It may be something like a capacitor that is very easy to change out. This may save you some $$$$.If this is an older model, you may want to look for another, but if its a newer, I would spend the time to do the things I have said. I wish you the best on this, and want you to save your $$$$ on this. Please keep me posted, and would you please rate me on any help I may have been to you? Thank you!

From your description it sounds like a bad magnetron especially if is loud laboring to run, the high voltage transformer is been loaded down by the magnetron and that is where the noise is coming from. There are two other parts that should be checked, the high voltage diode "opens/shorts" and the high voltage capacitor sometimes become defective.

Basic Microwave Oven Troubleshooting Tips

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

You may have a defective, keypad issue, or even a defective defective control board.

Careless troubleshooting of a microwave oven can result in death or worse. Experienced technicians have met their maker as a result of a momentary lapse of judgement while testing an oven with the cover removed. Microwave ovens are without a doubt, the most deadly type of consumer electronic equipment in wide spread use.

The power supplies for even the smallest microwave ovens operate at extremely lethal voltage and current levels. Do not attempt to troubleshoot, repair, or modify such equipment without understanding and following ALL of the relevant safety guidelines for high voltage and/or line connected electrical and electronic systems.

Hi

F3 is an error indication that there is a short in the key pad assembly. It is likely that this assembly will need to be replaced.

Be aware that Microwaves carry potentially lethal levels of voltage even when completely unplugged from the mains supply.

For this reason I recommend you get a tech to look at your microwave and you do not attempt any repair to a microwave yourself.

It is likely that the keypad assay will need to be replaced. This part costs usually around $100. You will also have a labour cost also to consider so you should weigh this cost up in economic terms before you decide to proceed.

Hope this helps. Please do rate this answer. Thanks.

In most cases that code means you have a shorting keypad.

If you could post the full model number, I'd be happy to point you to the best source in case you or a friend want to replace it yourself.

Otherwise, we regularly repair these for customers nationwide for $39.95 postpaid plus thew cost of the keypad.

This is usually caused by either a bad door switch, a loose door switch mount, or occasionally a problem on the control panel.

Even though a door switch clicks, it may still be bad inside. Its continuity must be checked.

Door switch or mount trouble can be caused by slamming the door or by opening the door while it's cooking without hitting the Stop pad first.

There are plastic mounts inside the microwave which hold the door switches and onto which the door latches lock when you close the door.

The screws on these mounts may be loose. If they get too loose, the switches will not be activated properly.

Sometimes it's a broken tab on the switch holder, allowing the switch to rotate just out of position. Other times, it's a broken tab on the switch holder, allowing the switch to rotate just out of position. This tab can be hard to see, since it is under the bottom edge of the switch.

One test that sometimes helps is to gently lift up (and/or push down) on the door or handle as you try to start it. If it works or tries to work, then it's a door switch mount or door alignment issue.

If you or someone you know decide to look into it, we have critical information on safety, disassembly and door switches at our site, and our link is at our listing here on FixYa:.

You can probably find exploded views and order parts by entering your model number here at the Sears parts site.

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

If you think the problem is on the control panel, we repair these nationwide by mail for $39.95 postpaid in most cases.

The motor that is running the turntable may be going bad.

It turns itself on

1. Interlock switch If your microwave is turning itself on, the first thing to check is the interlock switch. This is usually the first thing to malfunction that could cause this issue. If the interlock switch is bad then it will need to be replaced.
2. Main control board If your microwave is turning itself on and the interlock switch is still working, the probable cause is the main control board. If the control board is defective it will need to be replaced.

But before throwing parts at it give these folks a call... https://www.repairclinic.com/RepairHelp/How-To-Fix-A-Microwave/74-6-878350-/New/Kenmore-Microwave-Turns-On-By-Itself-721-85033010 Best to you

It looks like it is too old. Nothing in Kenmore or Viking. https://www.google.com/search?q=Kenmore+Viking+851.8250800+manual ..

You've found the proper location if you're seeking for the fuse for your Kenmore microwave. The fuse is often found in the microwave's or behind the control panel. You must take off the microwave's exterior cover in order to reach it. After you've identified the fuse, you may see if it has blown. If so, you'll have to swap it out for a new one. It might be preferable to seek professional advice if you are unsure on how to proceed.

If you are getting an F-5 error code on your Kenmore hood combination, it typically indicates a problem with the temperature sensor. This error code may occur when you are trying to use the convection feature, as you have described.

To troubleshoot this issue, try the following steps:

Turn off the power to the unit and unplug it from the electrical outlet.

Wait a few minutes, then plug the unit back in and turn on the power.

Try using the convection feature again and see if the error code reappears.

If the error code persists, you may need to replace the temperature sensor. You can consult the user manual for your Kenmore hood combination or contact Kenmore customer service for assistance with this.

If the unit is still under warranty, it's recommended to contact Kenmore customer service for repair or replacement options.

These are all the top suppliers, but that model number is not showing. If the display has gone dim, you can get an electronics technician to replace the capacitor that runs the display. https://www.google.com/search?q=Kenmore+Microwave+318279601B+parts ..
