Sylvania microwave blows internal fuse.

I have a Sylnania micro mod wd1000asp28krii-5s. It draws down our lights and blows the fuse in it when i turn it on. I replaced the internal fuse and again the same. We have gone through about 1 microwave a year. Can i fix this ? Any idea on the cause? Thanks,Dave

You can fix it without the aid of a repairman. Simply unplug the microwave and remove the outer casing. There should be a few screws around the bottom edge and back panel. Once you have the unit open, look for where the power cord comes in. There should be a circuit board with a fuse mounted to it. This is your input line filter. The fuse should be a 20 amp appliance fuse that you can pick up at any hardware store (Lowe's and Home Depot both carry them). DO NOT op test with the outer casing removed. Potentials of about 14,000 volts are present in the high voltage network of a microwave oven. Close the unit up BEFORE you power it back up. Let me know if this helps.

SOURCE: Microwave keeps blowing fuse

If it blows the fuse as soon as you hit the START button, it's almost certainly a shorted high-voltage capacitor.

If it blows a few seconds after you hit the START button, it's probably the high-voltage transformer. You'll possibly also smell a faint electrical burning smell from the rear vent after you shut if off.

If it blows the fuse as soon as it's plugged in, you probably have a shorted door switch, a shorted varistor, or an internally exposed wire shorting to the chassis, etc.

If it went dead almost immediately after pressing the Start pad, that\'s usually a shorted high-voltage capacitor.



If it went dead a few seconds after pressing the Start pad, that\'s usually a failing high-voltage transformer.

Why did my micro stop working?


I guess the main plug fuse does not blow for the same reason it does not blow and you can wreck a PC, although not certain why that is. I have a feeling from past work on a Panasonic that there is an internal fuse as well. This may have blown with the power surge.

How do I access fuse in a jmc7000adw? Unit is "dead", want to check fuse first before calling repair person


To check the fuse in the JMC7000adw you first should remove the power cord from the power source. Then remove the screws holding the outside cover of the microwave . The High Voltage circuitry may hold a residual charge that could be lethal so use appropriate care when near the High Voltage circuitry. The fuse holder is a plastic inline clamshell type that must be opened carefully with the fingers or pried open. The fuse holder is located above the micro-switches near the internal light socket. The fuse plugs into contacts soldered onto wires so carefully pull the contacts off each end of the fuse being careful not to get cut if the fuse breaks. Sometimes the blown fuse might come apart so you will need to force the fuse ends out of the contact using a small screwdriver or other small instrument that will fit into the end of the metal fuse contacts. After replacing the fuse with the appropriate size I suggest you might wish to see if the fuse blows again before reinstalling the cover. Most likely the fuse blows because of an overload in the circuitry or a short in the safety micro switches as noted in other posted solutions. These micro switches seem to be underrated for the current they may be carrying and the contacts will weld themselves together or intermittently stick together causing the fuse to blow as noted in my previous posting.

I need a capacitor for a sylvania microwave oven, model# WD1000ASP28KRll-5S, seems like everywhere i look, i draw a blank.


Try looking for a capacitor of the same type, capacitance and voltage rating, rather than one for this specific oven. I think you will find it is much more universal than you think. If it is a metal can capacitor, then it is what is known as an oil capacitor, and they are used in motors and all sorts of things.

Our sylvania microwave model sr11092b received a power surge that blew the internal fuse and would not run (it also fried the power converter in my rv)\r\nReplaced power converter, replaced internal fuse...


I had the EXACT same symptoms with my Sylvania SR1109sb after a power surge.
After some digging around I thought what the heck let me try holding down the Reset button and do a power off/on cycle and what do you know it worked !!!
Just pressing the Reset did nothing until the cycle off and on.

Microwave blows fuse when turn on


If it is blowing an internal fuse it could be a lot of things.

-short in the motor
-short in one of the other components
- gunk/dust could be causing a short

If it is your house circuit breaker/fuse then either the microwave draws too much current/amps for the circuit and you should try another circuit or you already have too many things/appliances plugged into the same circuit (not necessarily the same outlet) and need to unplug one or more of them so that the 'fuse' doesn't blow.

Food still cold after cooking


Is this a combi oven? If it is not-and only a micro then there is no heating element. Try it on micro(if its a combi) with a mug of water for approx 30 seconds to test it. If its a combi-is the micro function still working?
