Sounds like the 240v terminal block in the back of the oven may be grounded out.. either that or the yellow wire that runs up the back of the oven may be shorted..

Will not heat food


HELLO.

The solution to make your microwave oven to be able to heat food is detailed given below.

1 Make sure the door is closed. If the door is not closed tight, the microwave will not function.Sometimes food will get stuck in the door and prevent the latch from working. Use the paper towel to get the food out, then close the door carefully and listen for the latch to click.

2 Check the power sources. First, make sure the microwave is plugged in; the plug may have shifted or slipped partway out of the socket. If it is plugged in and still does not work, voltage test the outlet the microwave is plugged into. If you are not getting a reading, the breaker is probably blown. Reset the breaker for that outlet in your home's circuit breaker box.

3 Reset the microwave breaker. Take the back cover of the microwave off with a screwdriver. Inside you will find a motor. Most microwave motors have a small red reset button on them. Hit that button. Your microwave should work again if the breaker was the issue.

Thanks

Just bought a new rca microwave oven RMW1143 it keeps blowing my breaker.. how do i change the power settings or do you have any other solutions


As this appliance is only rated at 700 Watt which means it draws about 1200 Watts. A 15 Amp breaker is fine and if it is blowing a reason must be found. Is it an earth leakage breaker? if it is then is there a possible fault?
I would get the appliance tested for electrical leakage if the size of the breaker is not the problem.

Wife was cooking food, she says she heard a big pow and saw a blue light in the MW. Now everytime we turn it on it jumps the breaker. Everything else works fine.


It sounds like the Magnetron that produces the microwave energy that heats the food has failed and shorted out which is triggering the Circuit Breaker due to the overload. You could try taking it to a repair shop, but with the cost of labour and parts these days, it is probably more economical to buy a new oven especially if it more than 5 Yrs old..

When the microwave is turn on it trips the circuit breaker. The light and exhaust fan work but if you try use the microwave oven it trips the breaker. What is my problem. Thanks Mark


The magnetron is probably defective "heats food" and there are two other parts that work with the magnetron, the high voltage diode and capacitor which can be issues. The cost to repair will approach the price of a new microwave oven.

During the cooking for our Christmas dinner the temperature started declining from the 350 degrees to 280 degrees. We tried the top burner to make sure the stovetop was working and the whole thing shut...


Hi Jane,
Ouch! Sorry about the Christmas dinner. I sounds as though the circuit breaker tripped.
First, find the circuit breaker panel.

1 Check to see if a breaker has tripped. These breakers are double sided because stoves are
240 volt appliances, like the water heater or the house heater. There is a bar that connects
two single breakers together. The breaker will be slightly off center to the other breakers if it is tripped.
2 If it HAS tripped DON'T TURN IT ON YET
3 Go back to the stove and plug it in.
4 Turn on a top burner(not the one that may have tripped the breaker) preferably one that you know works that you don't use very much.
5 Go back into the garage and turn on the breaker.
6 If it goes on OK go back to the kitchen. You have done the first diagnostic test.
7 Check the burner to see if it is getting hot. If it is, turn it to high and then turn on the burner that blew the breaker in the first place. See if it blows the breaker again. If it does not. Turn on all of the burners that you know work. You have now done several Diagnostic Steps that are important.
8 If one of the burners trips the breaker, you have one of the culprets. If not, GREAT.
9 Shut off all of the burners
10 DO NOT TURN ON THE OVEN
11 Open the oven door and look very carefully with a flashlight at the bottom bake heating element. Look at the the entire element. If it blew (similar to when a light bulb blows) you will
find white powder around the hole in it or it will be completely broken, or have bubbles in it. Some indication like that. If so it has failed and must be replaced.
12 There is one other rare possibility, but it would not have blown the breaker. Many ovens have clock baking timers. These timers will, shut down the oven. If someone adjusted the timer and didn't turn the knobs in the exact right position. It will ruin the party shutting down the oven at the worst time. But it won't shut the stove top burners down.
IF YOU HAVE FUSES INSTEAD OF BREAKERS
If you have fuses instead of circuit breakers, Find several of the large cylinder shaped fuses to conduct the diagnostic tests I suggest. They are usually available at home depot.
RARE PROBLEM
One last but very rare occurence with breakers is their specifications sometimes change over a long period of time. If that is the case, they will trip and lower and lower overload levels. Simply Replace.

I hope this helps,
Good Luck
Best Regards,
Mark

Breaker blows


When you turn it on? You mean when you plug it in?

When a microwave blows a breaker but not the fuse, it's often a shorted monitor switch (usually the middle door switch) or one of the other two door switches, or a loose or broken door switch mount.
