Test this component and replace it any faulty. God bless you


  1. Check the power diodeThis electronic component is responsible for transmitting current in one direction. If the diode becomes defective it will cause your microwave to not heat. Test the diode and replace it if necessary.
  2. High voltage capacitorResponsible for storing electricity, this part is a key component in any microwave. Remove, discharge, and test the capacitor to determine if it requires replacement.
  3. Damaged magnetronResponsible for generating waves and producing heat. When your microwave is no longer heating properly, replacement will be required.
  4. Thermal CutoffsExamine the thermal cutoffs on both the magnetron and the oven itself. Take off one of the leads and using a volt-ohm meter on RX1, check the terminals. If you get a result other than zero, replace the thermal cutoffs.

Kenmore microwave 721 modeldoes not turn on and cook


A key clue is if it has a turntable does it turn? If not the issue may be with a safety switch the door engages.

Kenmore model 721 850 the cooling fan doesn't run all the time


This could be due to a intermittent micro switch, or a faulty cooling fan. This is critical in keeping the magnetron cool when cooking.

Displaying error F6. What does this mean?


It would depend on the full model number of your oven.

If it has a 721 prefix, it was made by Whirlpool (by LG) and has a stuck cook relay, which we can repair very simply for $39.95 in most cases.

So please post a new help request or contact me directly with your full model number and detailed symptoms.

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

Kenmore 721 microwave fan turns on by itself


I have the exact same problem with my Kenmore Microwave model 721 that we bought in October of 2005. The Fan will just randomly turn itself on even when we are not cooking. It has been doing this for the last few months and is starting to become more frequent. There is no way to turn it off except to unplug it for several hours.
Was there a recall for this defect ?

Plastic melted inside oven, dripping from ceiling Kenmore 721


The round peice in top of unit is a cover for the stirrer wich moves waves around for even cooking. The reason for it melting is almost certainly there is not enough paint in cavity and waves are shorting out to metal.CALL the manufacturer and depending on age of unit they may replace it free

Your model number prefix of 721 means it's made by LG / Goldstar.

F9 code on an LG means either a bad door switch or a loose door switch mount.

Even though a door switch clicks, it may still be bad inside.

This can be caused by slamming the door or by habitually opening the door while it's cooking without hitting the Stop pad first.

If you or someone you know decide to look into it, we have critical safety information, info on door switch diagnosis and replacement, and disassembly information 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.

Microwave not cooking


I would say you have a bad door switch or door switch mount, or your door is loose or out of alignment.

But since it's new, and under warranty, I would contact Goldstar (LG) customer service to have them repair it free.

Contact LG at 1-800-243-0000 or http://us.lgservice.com

Kenmore Microwave model 721 62624200


We see this a lot. The problem is almost certainly on the control panel, which we regularly repair nationwide for $39.95 postpaid.

This light failure often occurs when a bulb goes out and the filament shorts, or when the bulbs are removed or installed without first unplugging the oven from the power line. Either can cause such a failure on the controller.

Details of our service and critical safety information and disassembly information is at our site, linked here on Fixya:
