my microwave has no heat. everything else seems to work normally.
the capacitor is not charging so I replaced it along with the diode, the diode reads different #s than the original but it was matched to the capacitor which matches #s on my original capacitor. There is 120 volts going into the transformer when running but the capacitor still has no charge.

Could be a bad power transformer. You can perform continuity and resistance checks on the secondary windings, but it takes a very expensive and specialized meter to do voltage checks-VERY HIGH VOLTAGE. You must use extreme care.

If the diode is the incorrect replacement will this cause the capacitor not to charge at all? The original diode showed had no ohm readings in either direction. When replaced the capacitor still would not charge. Also when trying to match up a HV transformer which numbers do I need to check for correct replacement?
thanks, Steve

These diodes sometimes need an additional voltage applied to test with your ohm meter. If you don't get a reading, it doesn't necessarily indicate a bad diode. If the capacitor isn't charging, and yu replaced it with another one that isn't charging, chances are very good that the culprit is the HV Transformer. By the way, if you're replacing the diode, the arrow on the body (schematic symbol) points to chassis ground.

Input voltage, output voltage (if printed on xfrmr), wattage.
