Most have a resistor in parallel with the hi voltage capacitor,but always use an insulated screw driver to double check and discharge the cap to be on the safe side,but normally with in 30 minutes

My microwave is not heating anything. I tried different heating buttons, is unplugged it and replied it and nothing worked. This unit is about 3 1\2 yes old. Any ideas? Thanks

I am assuming that the microwave comes on and the timer starts? If this is the case then the 'magnatron' (the actual microwave emitting bit) has stopped working. It could be as simple as a blown fuse, a blown rectifier diode or the magnatron unit itself. If you want to have a go yourself, wait at LEAST half an hour after turning off and disconnecting the unit before you take the cover off to check anything. BE AWARE THAT THERE ARE VERY HIGH VOLTAGES BEING GENERATED. Without electrical knowledge and equipment just check the basics

My Intellichef microwave model #K0936 has stopped working. I've tried different outlets but the microwave is not responding. Is there an internal fuse that has blown or is the microwave dead?

If the fuse is blown the microwave will be "dead". The fuse is accessed by removing the cover. You can usually find the fuse by following the power cord into the microwave. Unplug the microwave and don't touch anything except the fuse as the capacitor can hold an electrical charge.

How do i replace blown fuse in sharp microwave mdl 4A59

Remove the outer cover but be aware that doing so exposes you to dangerous, potentially lethal, voltages even with power removed. Find the fuse and replace it with one known to be good. Reinstall the outer cover and test.

It's completely dead?? Not sure what happened. Power supply is fine.

Microwaves that suddenly loose power could have many causes with the easiest being a blown fuse inside the cabinet of the oven. To check for this unplug the unit and remove the screws that hold the cabinet in place. Be sure to not touch any of the electrical components inside to avoid shock. Visually follow the path the power cord takes as it enters the unit. The fuse ( usually clear glass with metal ends and cylindrical in shape ) should be located not far from where it enters the cabinet. Once located use a fuse puller or other means to carefully remove the fuse to check the element inside. If the fuse is blown take it to a hardware or electronics store for replacement. These fuses are cheap as this has happened to me before. Good luck!

I have a microwave (Emerson Model#MW8111 SS and after removeing the cover to determine why I am not getting power I found a switch in line with the nuetral wire that is some sort of Klixon. It appears to...

The thermal fuse cuts off power to the microwave if the microwave overheats. To determine if the thermal fuse has blown, use a multimeter to test it for continuity. If the fuse does not have continuity, replace it. The thermal fuse cannot be reset-if the fuse is blown, it must be replaced. (Caution: The microwave oven can store thousands of volts of electricity in its high voltage capacitor, even after the microwave oven has been unplugged. Due to the potential for electric shock, it is extremely dangerous to replace the electronic components in a microwave. Only a licensed technician should replace the thermal fuse.)

My spacemaker stopped working and no panel lights. It's not the circuit breaker. Any ideas? model JVM140001

Could be the fuse inside the microwave is blown. You will need to unplug the microwave and remove the front control panel. Inisde the microwave housing you will need to trace the electrical wire coming into the unit. Usually you will find the in-line fuse located on the black power wire. You can pull the connectors off the fuse and test it with a continuity tester. If the fuse is blown replace it but make sure you use the same amp rated fuse as you removed. If the fuse blows again then there is an electrical short somewhere in the microwave.
