How to check if a microwave magnetron is working?
You can check to see if the magnetron is working by unplugging the unit, removing the cabinet housing, safely discharging the high-voltage capacitor, and removing the magnetron. With your multimeter, you can check the charge from the terminals. They should read 2 to 3 ohms of resistance if the magnetron is still working. Then, use one probe to touch the metal housing that encloses the magnetron; if it reads zero, there’s a problem. This step should only be completed once the capacitor has been discharged properly using a rubber-handled screwdriver or other safety tool.

Why won't my microwave heat?
The most common problem we see with Samsung microwaves not heating is that they’ve accidentally been unplugged, or that a circuit breaker has been tripped, which essentially cuts the power off from the microwave. So for starters, take a look at your microwave’s power cord and make sure that it is properly plugged into the outlet. At the same time, you might also want to inspect the power cord for any signs of damage.#N#If you find that the cord is cut, sliced, cracked, or frayed, do not attempt to use your microwave. You’ll need to have the cord replaced before it will be safe to use. Alternately, if you can’t see anything wrong with your microwave’s power cord, the next step is going to be to check your home’s main electrical panel for any breakers that may have been tripped.#N#If you’re in an older home, you might have a fuse box rather than a breaker panel. Either way, if you find any tripped breakers (or blown fuses), you can try to flip the breaker back on (or replacing the fuse) to see if it will restore power to your unit. If not, or if you continue to experience the same problem, it’s likely a good indication that there’s a short circuit somewhere in your appliance.
