microwave circuit problem
Why would the below be happening?
1. 12 year old over the range microwave stopped working - no power. 2. Microwave on its own dedicated 20 amp circuit. 3. No other outlets or devices on this circuit. 4. The circuit breaker was NOT tripped. 5. Reset the breaker several times (off-on-off). Power restored to the microwave (enough to display the clock), but as soon as you try to cook something the microwave looses power and the circuit panel breaker is NOT tripped. 6. Assumed the microwave was bad and bought a new one. 7. Exact same problem with the new microwave. 8. Recycled the breaker several times to get power to the microwave again (so the clock displays), but did not try to cook anything. Unplugged microwave and plugged in a hair dryer. Tryed to run the hair dryer - no power and circuit breaker NOT tripped. 9. Microwave works perfectly when plugged into another circuit. 10. Assumed the circuit breaker itself was defective. 11. Replaced the circuit breaker with a new one and still have the exact same problem. So now logically, it seems that the only problem it could be is something with the wiring itself. This circuit has worked without problem for the last 12 years. Could someone provide some guesses as to what the problem might be? Thank you, Jess (search key word = JessJoeMama) |

Thank you, Jess (search key word = JessJoeMama) Sounds like a problem similar to the one I posted about a week ago. I have several lights that get power from one breaker. When it was cold that past few days, the problem went away but it warmed up again a little bit yesterday and the problem is back. I'm going to replace the breaker and see if that is the whole problem. David |

Thank you, Jess (search key word = JessJoeMama) Hi, Did you check with multimeter to see if power gets to the unit? Logic tells me unit is not getting the power. Broken wire or loose connection somewhere. |

Thank you, Jess (search key word = JessJoeMama) If it really is a dedicated circuit then the wire most likely goes straight from the circuit breaker to the outlet. I would check to make sure the neutral and ground wires are tight at the circuit breaker panel. Presumably black/hot is ok since you have replaced the breaker. Then pull the outlet and make sure the wire is securely connected to the outlet. If it is backstabbed then move the wires to the screw terminals. If all that fails then the circuit may not be dedicated and I'd turn off the breaker and start looking for other appliances or outlets that are now off. |

Shut off power to the outlet, test it with a meter (to make damn sure it's dead), remove the faceplate/outlet, then undo/inspect/redo the wirenut splices inside of the junction box. The symptoms do sound a lot like when a breaker goes bad, though. Jon |

Something else you might look into is if there is a main breaker upstream of the individual one serving the microwave branch. Jon |

If wires are backstabbed remove them and attach them using the screws. Actually, just replace the outlet in case it has a faulty connection, but use the screw terminals to attach the wires. |

Thank you, Jess (search key word = JessJoeMama) It takes two wires to make this circuit work. The hot leg is apparently fine, the neutral is apparently open. Either the neutral of a two wire cable is loose in the panel feeding the circuit, or the neutral conductor of a multiwire branch circuit is loose in another outlet box, which is feeding the microwave outlet, or the neutral connection to the microwave outlet is open |

Now I need to follow the wires and check every connection until I find the problem. At least now that I got into the breaker box I am sure which wire to follow. David |

microwave circuit problem
1) Bad connection at the socket
2) Neutral wire is loose 3) Corrosion on the metal bar, where the breaker gets its power Friend of mine had an air conditioner socket that did much the same thing.

Said he tried a hair dryer. Those have a low failure rate.
I'm thinking either bad connection on the socket, or loose neutral inside the panel. -- Christopher A. Young Learn more about Jesus www.lds.org ..

The neutral wire must have had a bad connection at the circuit breaker panel because the last 3 or so inches of the wire was fried. An electrician repaired it and everything is fine now. Thanks for everyone's help. Jess |
