Normally you would press Clock, enter the desired numbers, then hit Clock or Start. Try it with door open and with door closed.

Otherwise, contact Westinghouse Small Kitchen Appliances at 800-947-3745 or see http://www.saltoninc.com/contact/contact.html

Since it sounds louder than before, it is probably a bad high voltage diode or magnetron.

If it's within the magnetron portion of the warranty (usually 5-9 years) but out of the original full warranty (usually 1 year), then your manufacturer will cover the part cost, but not the cost to visit you or the labor charge to do the work.

Here are some links you or someone you know can use for test help, but read their safety warnings first:

Sears may send you a magnetron to install yourself since it's under warranty. For that or warranty service, contact Sears at http://www.sears.com.

You can save about $75 by taking it to the shop yourself, as opposed to an in-home service call.

Assuming that your internal cooling fan is working, I would suspect that your magnetron is failing.

You can usually find helpful exploded view diagrams and order parts by entering your full model number here.

There should 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, and locating components.

I would check the cooling fan, then suspect the magnetron.

Kenmore pizza microwave beeps constanly


This is not a solution, it is a clarification request, but it looks like FixYa took away that helpful option, too.

I would suggest you post a whole new help request and be sure to tell us:

1. The FULL model number from the tag in or on the microwave. A full Sears/Kenmore model number has 3 digits, a dot, then 8 more digits, such as ###.########

2. Let us know when it beeps. Is it only after cooking? While it's setting idle?

3. Next, let us know if the display has anything in it besides the normal clock time.

A good first step might be a hard reset, accomplished by unplugging the oven for a minute or two, plugging it back in, then resetting the clock.

HELLO.

The steps to the solution are as follows.

Off the microwave oven and it.

Then plug the microwave oven and power on the microwave.

Allow the microwave oven to load itself.

Then reset the timing program.

Test the microwave for normal operation.

NOTE:if the problem persist,cleaning the microwave is the next solution.Below is the solution to cleaning the microwave oven.
  • Remove oven racks and soak them in soapy water.
  • Turn on your automatic oven cleaner; this usually entails locking the door and turning the function switch to "clean."
  • Let the oven do its work; it will heat for several hours, charring off baked-on foods.

Thanks.

Error Code F-9 Sears Microwave Model 721.64683300


It is not the most straight forward job and can be quite tricky for the uninitiated.
If its under warranty ( but I guess its not looking at the model # , ) return it!

The cost of a magnatron and a board is expensive (It is likely they are both involved in this as there sound like arcing) I would just replace the whole unit. Microwaves are not expensive items these days, but ones own life fiddling with electrics is still quite valuable.

MY KENMORE 1000 WATT LITERALLY WORKED FINE ONE MINUTE THEN NOTHING THE NEXT. I HAVE NO IDEA WHAT HAPPENED.


Most likely the circuit breaker tripped or the fuse blew. A 1000 watt microwave is using 2/3 of the power available on a typical household circuit of 1500 watts. If anything else is plugged into that circuit u can have a problem. Just reset the breaker or replace the fuse and u will be up and running. if it happens alot you should consider a dedicated circuit for your microwave only.

Kenmore elite microwave oven displays "Locked" and will not respond


My Kenmore Elite microwave (don't have the model number in front of me) also mysteriously locked its own keypad (we were sitting in an adjacent room, heard a strange beep, and got up to find the LED reading "Locked."). I pressed and held down the Stop/Clear button for ~10 seconds and it returned to normal.

Kenmore microwave


If this has a controller that runs a microwave and an oven, then the problem F2 means a temperature related fault such as a bad temp sensor / thermostat or a defect in the control board. If it's just a microwave, then the problem is likely a failing keypad. In many cases, those can be replaced economically. If you repost with your exact model number (62622 is not a complete model number) then we can advise you further and more specifically.

Microwave's Power goes off after 3 minutes running..


If the time from START to shut off were EXACTLY 3 minutes, then I would suspect a sensor problem or corrupted code in the microprocesor. But since that time sounds more random, it sounds heat-related, and I would suspect a failing magnetron or a failure in the cooling system. If the cooling fan is not running while the oven is cooking, this failure can occur, and can destroy the magnetron in short order. A cracked magnet (has the oven been dropped?) or other problem can cause a magnetron to go bad and overheat. If it's under warranty, I would definitely contact the manufacturer (see your manual) to find an authorized local servicer. If it's out of warranty, I would balance the cost of a new microwave versus a bench diagnosis fee of $25 or more or an in-shop repair cost of maybe $80 or more.
