Answer Hello Ronnie,
This would be called the top burner ignitor 316011200
How can the rectifier and magnetron be tested? The unit made a loud pop, now it won't heat.
Brent for Model Number Frigidaire GLMV169DSA
Answer Brent, Basically your best bet is to have an analog test meter, that operates on 12 Volts DC.TJMA-12816A or has a diode test circuit. The diode/rectifier should have a "closed" circuit in one direction only. If there's no circuit at all or a circuit in both directions, the diode needs to be replaced. To test the magnetron, there should be less than 1 ohm resistance when the test leads are placed across the two terminals, and an "open" circuit from each terminal to the magnetron body casing. All wires should be disconnected when testing these components. Here's some meter usage information should you need it [http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html]. Thanks and Good Luck
What causes a microwave diode to go bad?
Plow
Answer Hello Plow. Usually over time components break down and go bad. Also, a bad magnetron can cause the diode to go bad. If the magnetron is good, and the diode is bad, just replace the diode 5304468869.
