My old GE Spacemaker II microwave (JEM21K001) died. I was using it, heard a little pop, and it lost all power. Is this something simple to fix like replacing a fuse or is it bulk trash at this point?

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.
