Question about Microwave Ovens

Microwave/convection oven problem

I have a 1988 Amana Microwave and Convection Oven Radar Range Model RMC720. On Sunday, I was using the microwave when, after several minutes, the microwave stopped; but the timer continued until the end. After it had been off for some time, the same thing happened. Since I was reheating pasta in a pyrex glass dish, I decided to use the convection oven. That worked for a few minutes, and then the same thing happened: The timer continued while the cooking process stopped. What do you think is going on, and do you think that this is a problem that can reasonably be repaired? I would like to get it repaired, if possible, because I have looked at the new microwave-convection oven combinations; and I like the one that I have better.

This is usually caused by either a bad door switch, a loose door switch mount, or a problem on the control panel.

Even though a door switch clicks, it may still be bad inside. Its continuity must be checked.

Door switch or mount trouble can be caused by slamming the door or by opening the door while it's cooking without hitting the Stop pad first.

If you someone you know decide to look into it, we have critical information on safety, disassembly and door switches at our site, and our link is at our listing here on FixYa: http://tinyurl.com/yzjozk

You can find helpful exploded view diagrams and order parts by entering your full model number here: http://tinyurl.com/gv383

If you think the problem is on the control panel, which we repair these nationwide for $39.95 postpaid.

Is the sharp above range microwave model r-1871t recirculating?


According to the Sharp product site, http://www.sharpusa.com/ForHome/HomeAppliances/Microwaves/Models/R1871.aspx , the R-1871 is a convection and microwave oven. The manual describes using the convection oven feature on page 18 (page 20 of the PDF). The direct link to the manual is: http://files.sharpusa.com/Downloads/ForHome/HomeAppliances/MicrowaveOvens/Manuals/mic_man_R1872.pdf . The convection button is on the top left in the middle group of buttons. You use the numeric power level buttons to set the oven temperature. When you program convection cooking, the 1 button will bring the oven to 100 degrees F. The 6 button gets the oven to 350 degrees F.

I hope this helps.

Hello MJ hartman,

Here's a link that will take you to a free downloadable copy of your Owner's Manual for the AMV6177AA Series combination Microwave/Convection (over the range) oven.

http://shop.amana.com/assets/pdfs/literature/amv6177aa.pdf

I also have a folder on my computer that I've labeled "Household Appliances and Equipment" into which I save an electronic copy of all Owner's Manuals and Guides for all the appliances we have, just so they're readily available without having to spend hours searching the web for them, again.

I hope you find this Very Helpful and best regards!

Amana convection/micro #AMC1580AB popping SOUND and sparks


That would be ACM1580AB, just in case that was throwing off your searches.

If the noise came from within the oven cooking cavity, it may be grease of food on or behind the waveguide cover (called a canopy in this case) which is fastened to the wall of the oven with two screws, apparently.

The cover and the area behind it must be clean.

If the canopy is burned or damaged it must be replaced.

If the sound was coming from behind the controls or on the right side under the outer cover, then it is probably a bad high voltage rectifier diode.

Here are some links you or someone you know can use for test help, but read their safety warnings first:

http://www.gallawa.com/microtech/diode.html
(if it's not shorted, it's probably okay)


http://www.gallawa.com/microtech/mag_test.html
(even if the magnetron passes these tests, it can still be bad. If you have high voltage and the diode is good, assume the magnetron is bad)

You can find helpful exploded view diagrams and order parts by entering your full model number here.

The actual service manual (with installation & operation info, too) is free to download here.

Your owner's manual is availabel free here.

We're happy to help you with free advice and we'd appreciate your thoughtful rating of our answer.

Amana OTR Convection Microwave runs 59 seconds and shuts off


This sounds like either a thermistor or a damper switch/motor problem.
Amana's technical support line is 866-426-2621. This is the commercial side but they should be able to get you in touch with the domestic side.

Amama 2.0 Cu ft. Radarange Microwave model# UXA3036BAB


This model does not list Stainless Steel as a feature. Stainless Steel is used in the interior (CAVITY) of a Microwave if it is a Combination Convection/Microwave Oven. The Convection Oven can reach temperatures of 400+ degreesF. This Temperature would MELT the paint off a painted interior.
Stainless Steel can be tested with a Magnet. It will not be attracted or "Stick" to Stainless.
Hope this answers your concerns!
Thanks!
