Why does my Whirlpool microwave not heat?
If the diode burns out, the magnetron won’t receive enough voltage to operate, preventing the microwave from heating. When the diode fails, it is often visibly burned out. Inspect the diode and if the diode is burned out, replace it.
Why does my microwave turn on but not heat?
If your microwave oven doesn’t heat, you may have a problem with the high voltage diode or rectifier. This component helps provide the high voltage that powers the magnetron. The high voltage diode is located near the magnetron and the high voltage capacitor, so access will require removal of the cabinet.
How can you tell if a Christmas light fuse is blown?
Open the sliding compartment door and remove the fuse(s). The fuse is a small, glass cylinder with metal-plated ends and an internal metal filament. You can sometimes tell by sight if a fuse has blown; the metal filament inside the glass cylinder will have a break in it.
What does a bad fuse look like?
A good fuse will measure near 0 Ω, while a bad fuse will measure OL Ω or ∞ Ω. Then, probe both sides of the fuse. Both sides of a good fuse will show power, usually indicated by a red LED. If the fuse is blown, one side will show power, while the other side will show ground, usually a green LED.
Why did half my Christmas lights stop working?
If half a strand is working and the other half is not, you probably have a loose or broken bulb. If not, you have the more tedious job of going down the row of unlit bulbs, one at a time, and swapping them for a known, good bulb until you find the culprit. You’ll know it when the strand lights back up.

Why is my pre lit tree lights not working?
Most likely a bulb is loose, and the connection is getting lost as the bulb moves in its socket. This often occurs through rough handling or improper storage of a tree. Look to find the loose bulb, check the wires to ensure they are properly aligned, and secure the bulb tightly within the socket.
