Blowing breaker


In general house hold circuit breaker of the house is 15 Amps or 20 Amps.

Either you have defected (weak) circuit breaker and wiring or bad Microwave oven.

The 99.99 % house hold Microwave ovens pull less than 15 Amps. They may have internal ceramic 15A fuse or 15 Amp internal circuit breaker.

To isolate your problem:

1. Plug your Microwave oven to different areas (different electrical circuit) if the different circuit breaker still trips... your Microwave oven has a short - Most of them has a small ceramic fuse 15 amps fuse.-also check some inter lock switches at door .

2. If the Microwave oven works Ok then you may have:

2a. You may overload the existing electrical circuit, try to unplug some other appliances

2b. You may have bad electrical outlet receptacle (Replace it with the same type , - may need helps from licensed electrician)

2c. Weak or defect house hold circuit breaker. (Replace it with the same type , brand - may need helps from licensed electrician)

Not heating


Hello


Power Supply

Check whether there is a proper power supply. Look to see whether the cord is connected to a grounded 3-prong outlet and the cord is fully plugged in. If the electrical system is built-in and no power cord is visible, replace or reset the household fuse or circuit breaker.

Microwave Functions

Some basic microwave operational steps may affect whether the microwave is heating. Open and close the microwave door, as the unit will not function with the door open, and push "Stop/Clear" to cancel any previous settings, such as the timer, which do not heat the microwave oven.

Setting the Microwave

Once the power to the microwave has been reset, or verified as working, and the microwave is ready to run, select a new cook cycle and press "Start" to see if the microwave begins to run and cook food as expected. Allow the food to cook for the alloted time and then open the microwave door and check to see if the food has cooked or heated. Choose a longer cooking time and restart the microwave if food is heating but is cooking slowly.

Repair

If all efforts to troubleshoot the function and power to the microwave still do not get the appliance heating food as expected, there may be a repair issue that needs to be addressed. Contact professional technician for advice.

I pluged the microwave in it was working and when I pushed it back and when I looked at it it waqs not working any moren mdl # is 87449 kenmore counter top microwave


Check the outlet it is plugged into. Remove the microwave plug. If you don't have a voltage meter handly to test the voltage at the outlet or the continuity of the microwave plug, I would suggest you plug in a lamp from your living room into the outlet. If it doesn't work, either the outlet is a tripped (GFIC) Ground Fault Interuption Circuit outlet or the circuit breaker tripped in your electrical panel box or the microwave cord is damaged and caused a short and blew the fuse. To check these I would try plugging the light in and press the red reset button located on the wall outlet or flip tripped circuit breaker in panel. If it's a damaged cord or fuse, you can visit this web site for Sears parts www.searspartsdirect.com If you found any of these suggestions helpful, please rate my solutions. Thanks D. Lange

I would suspect you have a failed high voltage transformer or maybe magnetron.
