20 Most Recent Amana ACO1840A Microwave Oven Questions & Answers


Yes, but ... If this truly is a failure, you're looking at replacing the clock/display/control board. This is usually a VERY expensive solution. In some cases more than it's worth as compared to replacing the entire microwave. The clock not 'sticking' is a rather unusual complaint. I'd highly recommend that you dig out the owner's manual - or check on-line for one if you can't find / don't have - to make sure you're not missing a step while setting the clock.

The magnetron may have either failed or is not being supplied with the extremely high voltage required to run it.
Make sure the !!!!capacitor is discharged!!!!! before attempting any sort of repair.
Check the diode with either an AVO model 8 on high resistance range for short circuit, the feed fuse on the primary of the high voltage transformer and then finally, the magnetron is best checked by substitution.
Hope that helps.

Hello

Depending on your technical skills , there are basically 4 components which you can check than normally cause this type of error in a microwave.

PLEASE READ HERE HOW TO DISCHARGE YOUR CAPACITOR AND SAFETY PRECAUTIONS BEFORE DOING ANYTHING!!!

Firstly , check to see if your microwave is fitted with a fuse. This will normally be located inside the casing and it is not very common for a microwave to have a fuse , so don't worry if you can't find one. If you are in doubt , let me know and I will look up to see if there is a fuse for you to check.

Open the casing of you microwave and look at the back right of the unit for the following.

HV Diode is located near the power supply and is identified with a symbol like in the picture below.

Check the diode for physical damage like a crack , bulge , burst or burned smell as they normally fail physically. To test , set a multimeter to test resistance at 10k ohms and test. A normal diode should read 50-200 k ohms. If not , replace the diode as it has gone. Remember that the polarity is important , so test it both ways (or put positive to anode of diode)

Next component to check is the HV Filter Capacitor. This component is a big circular steel tube on the board/mounted near the HV diode.
Locate and remove any leads going to the capacitor AFTER DISCHARGING THE CAPACITOR.

Now , set you multimeter to resistance again to the highest available setting. Now put it onto the terminals for a few moments (Should read infinite) and then switch the leads around. The reading should go to almost zero and then go back to infinite. Also test between each terminal and the casing (if not covered in plastic) and this reading should be also be infinity. This test might not work if your multimeter is digital and has a very high latency. If it's a good quality multimeter , it should work fine.

Also inspect the capacitor for bulges , leaking , a strong burnt smell or a crack and replace if any of the test fails. These capacitors are designed to fail at the top of the capacitor where steel is visible , so check here especially.

If neither the Diode or the Capacitor is defective and there is no fuse, by process of illimination , the only thing left is the Magnetron. Depending on how expensive your oven was it may not be worth replacing as it's a expensive component. In your case , it would cost about $50-$100 for the magnetron , so you might just want to buy a new oven.

Most of these components can be found or ordered at radio shack (diode and capacitor) or most any other electronics supply store or www.repairclinic.com (magnetron). If not , contact the GE directly.

Feel free to ask if you need more info or have any questions.

The first thing I would suggest is a hard reset. Unplug the unit for a minute or so. Then plug it back in, set the clock and try again.

If that doesn't work, leave it unplugged for about 5 minutes.

If it is just failing to start when you press "Start", it may just be a door switch or mount. See this file.

If several keys are not working, it is almost certainly a bad keypad.

There should be a "mini-manual" (tech sheet) hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting, testing, and locating components.

Your Amana Radarange is overdue for retirement. Best to not even try.

The magnetron is probably the single most difficult component to get to in the microwave. In my opinion I would just buy a new one.

Amana Microwave... • Answered on Feb 23, 2021


This could be several things: 1 the magnetron that generates the wave. 2. The high voltage diode. 3. The capacitor. Since it is a high voltage device and can injure or kill you, if you are not versed in electrical repair and replacement., call for service.

You can try checking out the installation manual for an idea of how it was installed. It should be sitting on a mounting bracket and not attached to the sheetrock itself. However, you might be pulling on the mounting bracket when you tip it forward. You should have an extra set of hands to help you pull it straight forward and out, instead of tipping it. The installation manual can be found at https://d1vofmza27mmhi.cloudfront.net/product-pdf/amana-amv1150vaw-installation-instructions.pdf. Good luck!

The LV control (mains side) fuse is on the control board. The HV (lethal side) fuse is housed inside a plastic shell, next to the HV capacitor. For both, the outer shell (microwave oven's cover) needs removal. BUT: Mains must be off, preferably about 15 minutes to allow HV capacitor to discharge through it's internal drain resistor. AND: There will probably be one or more security tamper-proof screws on the cover, to prevent accidental injury through electrocution. WHY: Microwave ovens are the most lethal household appliances to open when untrained hands poke around. SUGGEST: Get an experienced tech to check it out. What makes you believe it's a fuse?
