Fuses seldom just go bad on their own, but it's safe to replace. Before you replace the fuse, squeeze the tabs of the fuse holder clips together a bit. Sometimes they don't grip the fuse tightly enough, and this can cause heating which damages the fuse. If the fuse blows again there is a bad part in the oven that will need to be located and replaced. For a small countertop oven, it's probably more economical just to replace the oven than to repair it.

Line Fuse


Every microwave oven has a line fuse. This fuse is designed to blow if too much current is drawn through the microwave circuitry. The fuse can be replaced, but the underlying issue should still be investigated and resolved. Otherwise the new fuse will blow also.
Main Control Board


If the microwave is not working the main control board may be defective. This is not common. When a microwave stops working the problem is usually the line fuse or within the high voltage circuit; either the high voltage capacitor, diode, transformer or magnetron.


Thermal Fuse


If the microwave is not working the thermal fuse may have blown. It can be tested for continuity. Watch our fuse testing video for more information.
Thermoprotector


If the microwave is not working the thermoprotector may have tripped. This is a safety device to prevent the microwave from overheating. It can be tested for continuity to see if it's blown2_6_2013_8_43_03_pm.gif2_6_2013_8_43_37_pm.jpg

250v20a fuse blown just no heat


If there is spark please do not switch on unless you have confirmed the fault. It is possible that the Magnetron is leaking and sparking to the ground. As you have mentioned it was stored, it is quite possible that insect can get into the oven and create soft spots. When you switch on these will create a short and make the voltage jump and in the long run damage the magnetron.
So Remove cover after disconnecting , check for dirt/moisture in the cabin, if so wipe clean and dry, check the magnetron and area clean and use an jet air to clean off.
Now switch the microwave power on and use a cup of water to test.
If you notice any sparks shut off as the magnetron or the main HT capacitor can be faulty. Replace with same type. If not check the waveguides within the cabin for food particles that can burn and spark, check for rust that can corrode and spark when the ceramic paint has worn out.
If there is heating without any issues, you can use the microwave safely

Microwave light comes on and turntable revolves when food is put in, but it doesn't heat food up. Food remains cold, can you help? thanks Dee


9 times out of ten it is the magnatron that has gone bad, that is the device that creates the microwaves for heating the food. Check inside the cabinet for fuses and if none found or blown then it is the magnatron. These are available widespread but most cost about as much as a new oven, so do a google search on your make and model of microwave and search for a magnatron for that unit. This will bring up parts suppliers and their prices and you can decide if it is worth fixing or replacing

I have kitchen aid microwave modelkcms185jss starts runs fine but does not heat food at all.


Does not heat food means a problem on magnetron tube and fuse blown in high voltage area. Have it replaced and it will heat again.

it is obvious that nthe microwave side of the unit is not working.
microwaaves have a terrible habit of blowing fuses for the most stupid reasons. No not the fuse in the plug but the ones the manufacturer hides inside the case, you will have to look hard. if one is blown replace it with a direct replacement. and do not test the machine with the cover removed

Microwave arced, wont heat now


I'm assuming that it doesn't microwave either. If it does...then the heater is bad. Sears parts sells them. Second guess is a blown fuse or thermosensor. Inside the pad housing, locate the internal fuse and replace it if blown. The thermosensor is a black plastic bit about the diameter of a dime and 3/8 inch thick and clamped to the side of the unit inside the control area. Test it for continuity and replace if open. If not either of these, then you have power supply issues or control panel problems. My bet: the heater blew out. Often, this is caused when you heat greasy foods.

Not heating the food


sam..vane...two different problems.

Sam...find out if you've got power in the outlet you're using. If not, you've got to check to see if you've got a blown fuse in the unit. Also ...see below.

vane...chances are you have a power issue or the thermosensor which is used for a safety has blown. It is the size of a dime and 3/8 inch thick...black...two wires. You'll probably find it has opened. Found attached inside the control area to the side of the microwave heating area.
