Will not heat baby food for 13 seconds

There is a huge capacitor inside microwaves, and that description sounds like it is starting to fail. There are smaller capacitors as well. It won't be a door switch, they work or they don't.

I had two Panasonic Commercial microwaves in a pub kitchen, one plain and one was a combination machine and both had drop down doors.

It will need a magnetron and maybe a large capacitor soon

The magnetron is getting to hot and will eventually fail, especially when it is arcing, "a safety issue convern" the cause is the part mentioned above, or there is exposed metal on the inside cavity.

hi,the magetron is what heats the food...it has gone bad...or you have a burn mark on the cavity were you ,put the food in to heat up....please check the cavity first...next it will need to replace the magetron...hope this helps....

That's interesting. We have the same microwave and it just stopped heating food after 13 months. Would have expected more for the money. As above - any suggestions on how to fix it appreciated.

hi

power spikes are very damaging to a microwaves internal parts, it sounds like your transformer and/or magnetron are blown. if the unit is out of warranty I would recommend calling a repairman or getting a new microwave (the transformer & magnetron are expensive and dangerous to work on) also get a small single plug surge protector for the new one.

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 connection on the control unit circuit board
- bad magnetron or other high voltage part (such as a shorted diode)

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: http://tinyurl.com/yzjozk

You can usually find helpful exploded view diagrams and order parts by entering your full model number here: http://tinyurl.com/gv383

There should also be a "mini-manual" hidden inside the unit behind the control panel, which is very helpful when troubleshooting.

We're happy to help and we appreciate your thoughtful rating of our answer.

COINCIDENCE? Yes... :) So go buy another one, it'd probably be cheaper than getting the bad one repaired.

I'm assuming that it doesn't microwave either. If it does...then the heater is bad. Sears parts sells them. Second guess is a blown fuse or thermosensor. Inside the pad housing, locate the internal fuse and replace it if blown. The thermosensor is a black plastic bit about the diameter of a dime and 3/8 inch thick and clamped to the side of the unit inside the control area. Test it for continuity and replace if open. If not either of these, then you have power supply issues or control panel problems. My bet: the heater blew out. Often, this is caused when you heat greasy foods.

I always recommend that folks put food off-center on the turntable to assure more even heating.

 

It's a stirring action, so imagine how inefficient it would be to stir just by twirling a spoon in the center of your coffee!

 

Also, when you put your food off-center, you're not putting it in the same spot every time. That will help prevent repeated heating of the the same spot on the glass, which can lead to weakness and cracking.

 

The turntable generally replaces the stirrer, which actually scrambles and stirs the microwaves as they come out of the waveguide from the magnetron. But some models, notably GE's, have both.

 

So if you're placing the food properly and it's still burning, since it's under warranty, contact Sharp at 1-800-BE-SHARP (1-800-237-4277) to see about getting it checked.
