microwave/oven combo
My DIL has a bake oven with a combo microwave. The microwave died, and the
repair guy said that the microwave couldn't be fixed. I find that hard to believe. The unit is not that old. Are there things in a microwave that go out that one just absolutely cannot repair? I know there's a break even spot where the repairs cost more than a new one. She is giving us the old unit, and I'd like to see if I can get it fixed. Steve Heart surgery pending?

Also, have you been to this google group to pose your question? sci.electronics.repair. Without knowing more you cannot get any serious advice. |

I can imagine that would be in the "nonrepairable" category for a standard-duty repairman. -- |

I can imagine that would be in the "nonrepairable" category for a standard-duty repairman. Speaking of such ............ I called a repairman in Las Vegas for a built in oven. He came, charged $75, which he would gladly take off the bill if I had him do the work. The motherboard was shot, and it would be $650 to fix. I pulled out the unit, and got the tekkie sheets taped to the pouch on the side of the unit. Pulled the plug and reinserted, wrote down the error code, and found out it was the Interlock. Went to a local shop, bought one for $32, and fixed it. Called the company and asked for a refund. No way, Jose. So, I told them I'd be calling the local news channel that loves these stories. No, NO, don't do that, we'll have that refund right over there this afternoon when one of our guys has an appointment in that area. Check was in the mailbox before sunset. That's the scenario I'm afraid of, and I live in a very little town, so there's a good chance of finding an honest repairman here, but there's probably not a lot of them. We have a lot of social contacts, so will probably be able to find one once we get the unit up here. |

Actually, on reflection, the microwave oven lock is mechanical only; the solenoid is only for the clean cycle--it prevents unlocking until the oven has cooled. So, the idea of it being an unavailable part wouldn't be the problem of why the microwave was deemed unrepairable... -- |

snip reply: Yes, I know that, but the unit is 200 miles away right now. I was just asking about the concept of whether or not a microwave can be so dead that it cannot be repaired, no matter the cost. Of course if it is cost prohibitive, then that's a deal breaker. I have heard of mw's that couldn't be fixed. Maybe sealed parts. Out of production. Whatever. I had one that my property manager said was toast, so we put it in storage and put another in the vacation rental. The next manager saw it, and asked about it, checked it out, and changed a fuse, and it came back to life. I may be going to Vegas Thursday, if not, not until after Thanksgiving, WHEN I'M GOING TO GET ALL THE PERTINENT INFORMATION on it. I've got a combo unit. Got it brand new from craigslist from someone who had it in their newly built home but wanted a double oven instead. I've had to replace the microwave door, which of course cost more than a whole new microwave would cost (around $100). I can only imagine if the control panel were bad. I'm sure with enough money the microwave section could be fixed. It's really just a microwave bolted to an oven, though the microwave works off of 220V like the oven, and the control pad for the oven is up on the microwave. I got such a thing because it fit into the space we had (used to have a double oven), but it's not something I liked doing. Since it runs on 220V, probably the magnetron and fan are different than the parts you'll find in most cheap microwaves. If the one I have breaks then there are plenty for sale on craigslist. Used ones sell for $200-300. |

That's not what I'm envisioning; if it's new perhaps it is what OP has, though. The unit here includes the microwave in the bake oven cavity, not two separate units. The oven is size of conventional range oven; there's just no storage under the oven as in others as that's taken up w/ the magnetron, etc., that's free space in standard free-standing range. -- |

I remember a woman friend, many years ago, taking her (magnetic tape) answering machine in for repair. The shop owner called her a few days later to decla "It can't be fixed. The problem is in the circuitry." |

Are there things in a microwave that go out that one just absolutely cannot repair? In a microwave-only oven, yes, because repair is more expensive than a whole oven, but in a convection-microwave, I think only a broken oven cavity (has anybody taken a sledge hammer to it recently?) or a bad high voltage transformer can make repair uneconomical. BTW if this is a table top model, L-G makes one for GE and also for Sears, the differences being price and one having a touch panel while the other having regular buttons. A microwave oven consists of a fan-cooled magnatron powered by a high voltage doubler (capacitor, diode), connected to a high voltage transformer, connected to some control circuitry (simple relay or inverter) and the 120VAC. There's probably also a high temperature cutoff for the magnatron. Magnatrons cost as little as $30, the high voltage capacitor and diode maybe $20-30 for both, and my parents have a 30-year-old convection/microwave oven that's been fixed 3-4 times by replacing those components plus the hi-temp cutoff. Also ovens with touch panels may wear out their buttons or develop cracked solder joints from flexing too much. If your oven buzzed briefly just before quitting, there's a good chance the diode shorted. www.repairFAQ.org has lots of repair information, including safety information. Microwave ovens can electrocute (kill) you even when unplugged, because of that big capacitor, whose built-in bleeder resistor sometimes cracks and doesn't bleed down the 2,000 volts. |

I asked my wife, since she has actually looked at the unit, and I have paid it no attention at all while at my daughter's house. It's a microwave over a regular oven, all in one face plate. I would have never bought it, but they are getting a whole new one, and are giving us this one on hopes we can fixit, as I am known for fixing things in the family, and everything that goes to the landfill usually goes through my house first, and I've revived a lot of stuff. I may see it this week, or after Thanksgiving, and get some more detailed info. But thanks for the boost that it may be repairable. Steve |

Not a scratch on it and the glass turntable and owners manual were inside. It works fine, I think someone was moving and decided the new items I found were worth less than the space in their vehicle.
