The magnetron tube has a five-year warranty and the one-year warranty offered by Panasonic is automatically increased to three years by the Good Housekeeping Seal of Approval, which covers all Panasonic microwaves.
Other parts, like the motor for the turntable and the magnetron, should be replaced only by individuals who are knowledgeable about how electronic devices work and who are skilled with appliance repair.
Other parts you can usually order are monitor switches, magnetron assembly (dispenses heat), and circuit boards, if you have an electronic panel.

While working on the radar research project, Dr. Spencer was required to test out a new type of vacuum tube called a magnetron.
He began to deduce that the magnetron had caused the candy bar to melt and to test his theory he tried out some popcorn.
Spencer placed the popcorn kernels in the path of the magnetron and, sure enough, the popcorn kernels began to pop.
