    Same problem as TP33. It was on for a long time (30 min +) cooking a bunch of potatoes on high.

  • kboyd Feb 21, 2008

    We have the same heating problem as TP33's. However, our microwave is now stuck in a mode where it runs (without generating heat) while the door is closed and no time set. The only way to cut the power is to keep the door open. Hitting stop / clear on the keypad has no affect.

    I'm guessing that it's a combo of the problem causes mentioned - faulty door latches, bad circuit board, etc.

    Help?? The oven was a gift! Does warranty cover this type of defect or is it subsequent to misuse? Thanks.

    microwave will not heat anything! turntable move and lights are on. It says power 100

    Made a strange noise, ran for bit (don't know if it heated then). Next time I used it, it blew the fuse for that whole section of the house.

    It seemed to work after that -- until I realised it wasn't heating anything.

    This is frustrating -- it was manufactured less than 2 years ago. I'm not buying Kenmore anymore.

    The timer, clock, etc. on the screen works and the light inside the microwave lights up. The turntable also turns; but there is a strange noise when it is slowly rotating and is in "cooking" mode.

    Tried 3-4 times to heat cup of water and no heat. Is the magnetron no good???

  • llwilk Sep 20, 2008

    Everything but the actual heating part seems to work.

    The noise is different. However it is not so different that it would be notice had it not stopped heating. I have two of the same models inside the house. The sound has a little more of a buzz to it.

    It was manufactured June 2005. I have had it for a little less than 2 years.

    It also blew a fuse for a whole section of my house.

    We've got the same problem with the 63252. Bought this maybe two years ago as a replacement to a 15 year old unit that came from my grandmother.
    Now suddenly the lights come on, the display panel works, the turntable
    turns, but no heating. Don't American (or should I say Chinese?) companies
    make products that last anymore? I have enough other little projects around
    the house (my Sears Craftsman Garage Door Opener just broke, but that's
    been in the house since 1987) that I don't feel I should have to be repairing a
    two year old unit! If it's the magnatron I'm considering taking Sears to small
    claims court!

  • Anonymous Jan 10, 2009

    I have the same model. It stopped heating and it is only 1 year 2 months old. The Magnatron is bad. I am very disappointed =(.

    It is a Chinese made LG magnatron.

  • Anonymous Feb 12, 2009

    Same problem, everything works but will not heat.  This a Kenmore model no. 721.63252301.  This is the second time this has happened.  The first time Sears replaced the magnatron for free (that was a little over one year after we bought it.  Now, another year later and the same problem.  This microwave is definitely not worth the money.  We previously had a Goldstar that lasted for over 10 years that never gave us any problem during that time.  This Sears unit is an inferior product and I bet they know it.  It's junk.

Generally, the most common causes of a failure to heat are:

- bad door switches or door switch mounts
- loose connection at the magnetron
- problem or loose conneciton on the control unit circuit board
- bad magnetron or other high voltage part

If you or a friend decide to look into it, we have critical safety information, info on door switch diagnosis and replacement, and
disassembly information at our site, linked here on Fixya:

Will need to pull apart to check....common failure with magnatron fuse....but could be magnatron, capaciter, diode. sugg to have a tech look at....if your not able to check, also call manufacturer, sometimes will cover.

SOURCE: KitchenAid Microwave Model KCMS1555 does not work

Assuming your inside light, turntable, and internal cooling fan all come on when you try to microwave, with the symptoms you have, I would most strongly suspect a shorted high voltage rectifier diode or a bad magnetron, or a loose and possibly corroded connection on the magnetron's terminal.

The diode is a fairly cheap fix, and the mag will cost more.

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

There should be a "mini-manual" (tech sheet) 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.

d:%5cele%5crepair%5cmicrowave%5cge_hotpoint%5cmini_manual_behind_grille_small.jpgAt our Web site, we have a video available showing how to remove a typical over the range control panel assembly in under 5 minutes.

If you don't find your mini-manual, or if you want to look at it before removing the controller, you can download it here.

Here are some links you or someone you know can use for test help, but read their safety warnings first:
(if it's not shorted or burned, it's probably okay)

You can find links to helpful exploded view diagrams and part ordering help here. I recommend that you bookmark that link to your favorites.

Accessing some components for testing and possible replacement will require you to remove the oven from the wall.

If so, the installation instructions are very handy, and it's best to have two people since the microwave can be heavy and awkward.

You can download owner's manuals and installation instructions for several brands (including Amana, Jenn-Air, Kitchenaid, Litton, Maytag, Roper, Tappan, Thermador and Whirlpool) here.

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 (usually $75 -90) or the labor charge to do the work(usually $75 -90 more) . See the model tag in or on the unit for the date of manufacture.

If nothing else, you can save about $75 by taking it to the shop yourself.

Dacor dcm24s.light, fan, and control panel work but turntable and heat do not

Most likely the bottom door switch. Dacor units are built by Sharp and that switch is a very common problem. You'd either need to check the switch with an ohm meter or remove the cover of the switch to see if it's burned inside.

Won't heat

Do the inside light and turntable come on when you try to cook?

Is it making any unusual noise or is it louder or quieter than normal?

Do you have the model number?
