Question about Kenmore 62622 Microwave Oven

1 Answer

My microwave magnets keep cracking

My microwave is a Kenmore 721.62629200 The first time my microwave went bad after 7 years I found that the connections on the magnatron had burned thru the housing and was shorting out on itself. I bought another magnatron and only after a couple weeks one of the magnets cracked. I bought a second magnatron and this one lasted about 2 months and the bottom magnet cracked again. This time I replaced the magnatron, transformer and capacitor. I've only had it installed one day and it already has started that familiar loud buzzing again. I'm afraid to cook anything over two or three minutes for fear of the magnet heating up and cracking again. For whatever reason the magnatrons are getting very hot or the magnets are getting hot and cracking. Anybody have any idea why these keep magnets are cracking? Thanks

Amana MVH210W keeps blowing fuse


The magnetron is more than likely the problem, or the inverter board if oven is 7 years old or less. If you have a digital meter you can do a rough test on the magnetron, unplug microwave, set meter to ohms, disconnect one wire from magnetron and put the test leads across too points, if reading is .2ohms or less it is good, but if the test shows infinity or open the magnetron is bad, keep in mind it may have a short making the reading misleading.

Microwave Won't Heat Food


My Kenmore 721.63259301 would not heat items up so I came here and saw the parts required and was just about to order them when I checked the online owners manual and found this. FULL FIVE-YEAR WARRANTY ON
THE MAGNETRON For five years from the date of purchase, if the
magnetron in this Kenmore microwave oven
fails due to a defect in material or workmanship,
Sears will repair it free of charge.
My microwave has a manufacture date of July 2009 so I will be taking it right to the closest Sears repair center for a free repair. I suggest everyone do the same.

If the microwave is arcing, or if a cooling or ventilating part is at risk, that can be dangerous.

But of course any time anything is broken or otherwise not functioning properly, it should be fixed as quickly as possibly to prevent it from getting worse.

Their warranty will normally cover in-home service on parts & labor for the first year, and just the magnetron itself for 7-10 years after that.

Specific warranty terms are in your owner's manual.

For repair service on Kenmore appliances, see Sears Service.

Where can I get a HV transformer for Microwave?


I went on-line and found a site that gave answers to similar problems. I found that no power to the the control board usually meant a transformer issue. I checked the leads on the transformer (with a meeter) and found that it was shot. Now I need a replacement transformer, at a reasonable price, or else I will purchase a new Microwave.

Magnatron Heat Sink Gets Hot But Not Food


Important: Does it sound any louder or quieter when cooking than it used to?

If the magnetron's getting hot, you're getting high voltage.

Chances are it overheated and the magnet cracked.

If the internal cooling fan (usually separate from the vent fan) fails, that will allow it to overheat, too.

If it's within the magnetron warranty period, Sears will cover the part, but not the labor to visit you or do the work.

Microwave just went dead


If there is no display and nothing works it may be as simple as a blown fuse. Try that first but unplug the unit before you do anything.
