oven wont come up to temperature in self clean mode. might reach to 500 to 600 degrees.
Answer Hello Saw,
This will have to be one of two issues. A poor electrical connection to the unit or in the heating circuit or a failing temperature sensor W10131825. Test the sensor with an ohm meter and look for about 1100 ohms of resistance with the sensor at about 70°F. Be sure to tap on it during the test since a bad sensor can make internal contact temporarily at room temperature.
Microwave not heating.
Answer Hello Dixie. You most likely have a "high voltage" side malfunction. Transformer, diode, magnetron, Capacitor. You will need to be extremely careful if you decide to test the components with a multi meter, Very high residual voltage is present, so make sure you remove power to the microwave and short across the terminals on the capacitor. The magnetron should have a reading of less than 1 ohm resistance across the two terminals, and an "open" circuit between each terminal and chassis ground. The diode/rectifier should have a resistance reading in one direction only, no resistance, or resistance in both directions indicate a faulty diode. The primary winding on the trans former should read approximately 450 Ohms resistance, the secondary winding should read 80 ohms resistance, and the filament transformer should read 100 ohms resistance. If all the readings are proper and in range, replace the magnetron.
