Amana MVH210W keeps blowing fuse


The magnetron is more than likely the problem, or the inverter board if oven is 7 years old or less. If you have a digital meter you can do a rough test on the magnetron, unplug microwave, set meter to ohms, disconnect one wire from magnetron and put the test leads across too points, if reading is .2ohms or less it is good, but if the test shows infinity or open the magnetron is bad, keep in mind it may have a short making the reading misleading.

It is the magnetron, "heart of the microwave oven" or the inverter board is bad, "less than 7 years old"

Ald10t fuse keep blowing


If the fuse blows when you open or close the door, then the problem is with the monitor interlock (middle door switch) or its mount.

See my help file on door switches here.

If the fuse blows almost instantly after pressing the "Start" button to begin cooking, then it is a shorted high voltage capacitor.

If it blows a few seconds after pressing "Start", then it may be a bad high voltage transformer.

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

You can find helpful exploded view diagrams and order parts for most Amanas by entering your full model number from the tag on the oven here.

The fuse to the Power cord on our amana hdc21 blows when you start cooking a product why?


How many other electrical items do you have working on this same fuse? Lamps, radios, tv's, fans, air conditioners, refrigerators, etc. can all put stress on the circuit causing the fuse to blow. Check the fuse to see what else it controls. You may have to move your microwave to another outlet...2100 watts is very powerful and draws a great deal of electricity. Or you may just have to turn off a lamp, tv, radio, etc when using your microwave.

Is there a fuse or breaker inside this model.


If the model number is correct, there is a 125V, 20 AMP line fuse inside the microwave. Its usually mounted at the point where the power cord enters the back of the unit. Unfortunately, you will need to uninstall the oven (if this is an over the range model), UNPLUG it and remove the exterior case to access. The case comes off in various ways depending on manufacture and model. I found this illustration at pcappliancerepair.com based on the model number you listed this question under:

http://pcappliancerepair.com/model-display.php
The line fuse is listed as item 12 (part number 56001353). Keep in mind, there are different vairations on the model number you provided. You need to look at the model number you have and include the last three letters as well. I reviewed most of these models and they appear to all have the same parts. You can usually purchase a box of fuses at a hardware store for just a little more than what the manufacturer charges for a single fuse. 125V, 20AMP Ceramic Slow Blow fuses are recommended. If you wish to order on line, use the part numbers to search by comparison as the model number you listed this question under may not be available at all the websites I have provided. The parts, however, ARE listed.

If you have any questions, or need additional assistance troubleshooting, please post back and let me know. I hope you find this information helpful.

NOTE: Make sure you take any resistance readings with the microwave UNPLUGGED and the component under test isolated (removed) from the circuit. These ovens can blow a fuse by simply sitting idle. This can occur from any power fluctuations, brown outs, voltage spikes, etc. Or, it could be the symptom of a component that may have failed. If you find the internal fuse blown and replace it, only to have it blow again, you have a more significant problem than a simple blown fuse.

My microwave oven keeps tripping the circuit breaker.i replaced the outlet that it plugs into but it still trips it. is there an internal fuse in the oven that may be bad?


If a fuse inside had blown, that would definitely reduce the current flow rather than trip the breaker.
I have replaced several breakers over the years; they no longer last forever.
Try your Amana on a different circuit, not in the kitchen; if that other circuit likes the oven, the breaker is bad. If the alternate circuit breaker also trips, then you have not a blown fuse in the Amana but rather a shorted component inside and repairing the oven will likely cost about the same as replacing it.

Possible fuse -- no power


Replacing a fuse Locate your fuse. Most microwave fuses look like the one pictured to the left. They are usually an inch or two long. Each end is metallic and the center is either ceramic or glass.
To get to the fuse, remove the outer cabinet of the unit, which is usually held in place with a few screws. Once the outer cabinet is removed, follow the power cord into the unit. It will take you to the fuse holder, where the fuse sits. The fuse holder is located two or three inches into the unit, and may be attached to a power board.
Decide if your fuse is blown. A blown glass fuse will produce flash burn marks on nearby surfaces, or it will be completely black on the inside. The internal fuse wire (filament) will be melted and blackened. Ceramic fuses give no outward signs of having blown. To determine if a ceramic fuse is blown, test it with an ohmmeter. If the ohmmeter reads zero ohms, your fuse is fine. A reading of infinite ohms means your fuse is blown.
Replace the blown fuse. Pop it out of its holder and snap in a new one. You can squeeze the fuse clips together with your fingers in order to tighten their grip. Replace the unit's outer cabinet, plug it back in, and test to see if it is running properly. DO NOT run the microwave with nothing in it.
NOTE: Fuses do not usually blow on their own. A fuse may blow because of problems with the interlock switches or with high voltage circuitry. It is also possible, though rare, that a power surge will cause a fuse to blow.
