Microwave oven does not heat

my microwave is Frigidaire MWV150KWA. When I tried to heat the food, press START, fuse break jumped and disconnect the microwave. Pull fuse break back, its exhaust fan works fine, surface light works, clock also works. Only can not heat the food

 

Since you reset the breaker and it no longer trips.... the fault is clear. I'm guessing you have it on a 15A breaker as otherwise the internal fuse would have blown.

There are two things that can cause a short..... a safety door switch and the HV power supply.

In order to do any servicing on the unit it needs to be remove from its mounting and opened up. You will need a decent meter to do internal testing. If you aren't handy with electronic/electrical items then this may not be a repair for you. The microwave power supply is high voltage.

This is a basic microwave oven and my recommendation would be to replace it.

 

The circuit break is in general electrical panel in the garage, and it is 20A. Reset break, everything works, but heat. Is there any possible, that there is circuit short cut, when I press "START"? I have home warranty, but the max. cost is limited to $200. I wish to know where it is wrong possible, before a big bill comes.

 

If the breaker is on and the light and fan work, the microwave heating properties are at fault. It is not really something that is user friendly. If the HOW will pay $200, you could replace the unit as its original "new" cost is between $169 and $219

 

I see it is a over range one. Just did a quick search at sears found new one's from 200$ up. Also looked at Magnetron which is a common part and one I found was 181.96 without labor, Not saying that what is wrong but could be.

 

Thanks for the helps. This is the 1st time to claim to HOW. As normal procedure, I have to submit claim to HOW, "Select Home warranty", then they will send technician come to check, I will pay $60 for call fee. After check, If need replace, he will order, which price may much higher than market price as most dealer does, then install it. It will cost lots. After $200, every penny, I need to pay. How can I reduce such cost, such as talk with HOW to let them pay their shares to buy microwave and let my friend to help me to install? Is there any has such experiences or advice?

 

Go to Sears and buy a new microwave and install it yourself. Only out of pocket cost would be the microwave, which would be less than the call fee and installation fee provided by the HOW. You will still be out the $60 for the service call, even if they allowed you the $200 allowance, so now you only have $140 to work with.
