Kenmore Spacemaker Fuse Blown

If it was run without the fan a thermal protect device was more than likely taken out. Check for that and replace the fan.

HELLO.

take on these steps to solve the problem.

Check if there is electric power on wall outlet.

If the microwave plug has fuse,check if it has not burnt.if these are okay there is need to take the last step.

things needed
1.Screwdriver
2.Ohmmeter
3.New fuse

1. Unplug the microwave from the electrical outlet to prevent electrocution. Place the microwave in a well-lit area to be able to locate the fuse.

2. Use a screwdriver to remove the outer cabinet of the microwave, and follow the power cord to the fuse. The fuse is located 2 to 3 inches within the microwave and is attached to the power board.

3. Observe the fuse to determine if it is blown. Blown glass fuses will produce burn marks on nearby surfaces, or the internal fuse wire will be black and melted, while ceramic fuses show no outward appearance of being blown.

4. Determine if a ceramic fuse is blown by testing it with an ohmmeter. If the ohmmeter reads zero ohms, your fuse is not blown. Other readings on the ohmmeter show that your fuse is blown.
5. Replace the blown fuse by popping it out of its holder, and snapping a new fuse in its place. Tighten the fuse clips by squeezing them together with your fingers.

6. Replace the outer cabinet of the microwave, and plug the microwave back into the electrical outlet. Test the microwave to see if it's working properly.

Thanks.

Yes.Water can only drip between the glass on the door when the door do not seal properly due to dirt on the microwave door.follow these steps given below to clean the door.

Did you check the internal fuse? Often when everything is dark the fuse that protects the microwave is blown. Take the old fuse to your local hardware store and they will have a replacement for you. Should cost less than $5.

sounds like you magnatron has finally gone bad after 18 years you are very lucky to have had it that long.in todays market it will be more cost effective and cost less to go buy a new one versus having this one fixed
i hope this is helpfull to you good luck

I just had the exact same problem. :( Did you find anything out?

Possibly a blown fuse inside, or a defective magnatron. If you decide to open the unit, please unplug it first!

A microwave can be dead for many reasons.

If it goes dead for a while during or after cooking then comes back on, the magnetron is probably overheating and causing the thermostat to open.

When it cools, it closes the circuit and allows power through again.

If it's random, it may be a bad connection, usually on the control board or fuse holder.

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.

If the fuse is good, it may be an open thermostat or thermal cutout on or near the magnetron or on top of the cavity / body of the oven.

Inside unit is a cylinder fuse which can blow for a number of reasons. External cover needs to be removed to access. If you are confident in doing this and can find & check the fuse then it would be my first guess. If fuse is OK then you will need to have repaired. If fuse isblown & you replace then it blows again,you will need to have repaired. regards
