Question about Microwave Ovens
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.
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,
