The fuse inside was blown and on opening found the blown fuse broken. replaced it and it is working. however the blown fuse was smaller in size while we replaced with a bigger size. does it matter???


you must replace the FUSE with the same capacity for example: you will see in the metal fuse the incription 240vac-15amp see if the fuse is Ceramic or Glass, you CAN not use 125vac,10amp or 20amp, the circuit WILL not protect the electronic system, and will dammed another section. Please rectify this INMEDIATELY.
God bless you

Not heating. where is fuse?


Remove the outer cover. If the fuse is blown, there is usually a reason--a shorted high voltage diode and/or a shorted 'stirrer' bearing, which is a fan-like device near the area where the microwaves enter the cooking cavity and under the sheet-metal waveguide from the magnetron. Replacing just the fuse usually results in another blown fuse.

Microwave shorted out when metal grease filter contacted inside


It might be that the internal power fuse of the MW may have blown. You may have to just replace that fuse if possible. Other wise the electronics (most likely a circuit board) may have been blown.

open by unscrewing screws on back and along left side bottom. this lets you swing up the cabinet showing the electrics. the red power line going to the timer is held in place by a metal wire holder that is riveted to the base. wire has a white sleeve between its insulation and the metal wire holder. slide wire and sleeve out to the side of the holder. slide sleeve to side along wire, revealing fuse. need a solder iron and an electronic parts store to get replacement fuse and solder it in. reassemble.


the fuse is a resistor that blows when unit is getting hot. use lower resistance fuse or just hardwire the power line straight through, no fuse, but watch for overheating (not likely) and maybe use breaker outlet

No power


Simply use Safety. Unplug. Use Continuity Buzzer, Meter ( With Continuity Tone ). Can Use Meter if You Have & Watch, Check By AC Power Cord Fuse. Use a 500 Ohm to 5000 ohm Resistor on two Insulated clip leads with screwdrivers and Find the Hi-Voltage Capacitor ( Large Metal with Leads and a Diode on it. Short the Condenser from one side to another to BLEED any Voltage left Charged in the Condenser. Newer Microwaves have a Bleeder Resistor 10 MegOhms Built in. But Just do this for Backup/Sure Safety. Will Probally Just find a Blown 15-20 amp fuse ( Electrical Surge ). Any one of the 3 Door switches that DONT open-Close Smoothly Will Blow Fuse. ( Intermittent, Burnt, Skipping, Hanging up ). A Shorted Hi-Voltage Capacitor or Diode Will Blow Fuse. Open in Series Protection device may have opened because of Overload or Surge. These are Metal and loop in-Out AC Line and are Mounted ( Heat Sinked to Metal case ).

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.
