Microwave drawing too much power
I have a Panasonic microwave that keeps throwing a 20A breaker. The
data plate on the microwave says it should draw 12.7A max, and an amp clamp confirms that it's pulling 21A What could cause this? Is it likely to be fixable by an amateur, or is the microwave history? It's only about a year and a half old, but it's been heavily used in an office setting. (maybe it's time to go with a commercial rated unit) |

Also, try and make sure, you dont have a fridge plugged in on the same circuit. Microwaves, cycle on and off, and when it cycles is when you need a big surge of juice. Also, if on same circuit with fridge, the compressor cycling on and off, will definately affect the fridge. Are you using an extension or directly plugging in? What else is using the same circuit? Have you always used it in this location, or is this something new.? Would like to help, but need some more info? Much regards |

Microwave drawing too much power
mine is making weird buzzing noises and making sparks. I think it's fried.
I admit I'm quite spoiled and dread the thought of doing without one. I'm of an age that predates microwaves in every kitchen. But can't afford to replace this one.

I've had several and though the Sharps are awesome, for the price, an Emerson is unbeatable ($50!). Perfect potatoes with the potato button, perfect popcorn w/ the p/c button. Get the one with the big glass rotary plate (don't break it!... cost 70% the price of a whole new m/w). nb |

(maybe it's time to go with a > commercial rated unit) Microwave ovens have very high voltages inside, thousands of volts, which can be stored in capacitors even when the microwave is off. There is also the hazard of high power microwaves leaking out if you don't put it back together properly. I would advise you to get a new one rather than risk your life trying to fix it. Microwaves don't cost much these days so if all the users in your office put in a few dollars you could get a nice new one. -- ----------------------------------------------------------------------- To reply to me directly: Replace privacy.net with: totalise DOT co DOT uk and replace me with gareth.harris |

Microwaves don't cost much these days so if all the users in > your office put in a few dollars you could get a nice new one. I second what Gareth says. You can buy a darn nice microwave for less than $100 these days. Cheaps ones are less than $50. Way less trouble to buy a new one than try to fix the old one. Now, with all that said. I would check to see if something is binding the turntable. Electric motors draw their highest current as the approach stalling. So gummy stuff in the turntable bearings could cause a unit to draw high current and *might* be fixable. I'd still recommend tossing the old one and getting a new one. Bill Ranck Blacksburg, Va. |

Most retailers won't repair them. If you toss it, you have to recycle it so it gets broken down correctly; you can't just toss it in a dumpster. Get one of the inexpensive Sharps - they seem to do a good job. N. |
