I purchased 3 times this magnetron model for my KEMS378SSS04 dual oven. Again returned to damage, not hard working more than three months. What should i check to make sure that other parts might be causing damage to the magnetron. let me know thank you.

Hello, For testing the Magnetron,my documentation from the manufacturer says I should have 45 ohms between the two terminals for a normal magnetron, and infintie for abnormal. However when I test from terminal to terminal I get a reading of 0.00, or no resitance at all. Does that mean my magnatron is bad? Thanks, Mark

The microwave does not heat. Front display shows all working OK. No error code. I have replaced the Inverter board with no success. Measured power to Inverter is OK. Measured Magnetron terminals with ohmmeter and is less than 0.5 ohms. Terminals to chassis is open. Could the Magnetron still be bad? Or could it be something else?
