Mike for Model Number PSB1001NSS GE Advantium PSB1001NSS Microwave makes a pop noise and no longer heats. With the cover off, when the microwave is started, there is an arc (pop) between the low voltage heating circuit wire and the top of the transformer. This is connected to the same post on the Magnetron as the lead from the capacitor. All the diagrams I found refer to it as F. I cannot figure out where the issue is. I hate throwing parts at a problem. Can you provide any guidance? The 20 amp fuse it good. The door interlock and monitor switches all work properly. The Diode when connected to a 9volt battery it shows 5.75 v the correct direction and hooked up backwards 20 mv. I suspect that is ok. The following all sound correct based upon specs I've found. using a multimeter: The primary circuit on the transformer =.5 ohms Red lead from the transformer to capacitor measures 90ohms to ground. Documentation states 87. Is 3 ohms significant? No leads from the transformer are improperly shorted to ground. Neither post on the capacitor or magnetron are shorted to ground. If I measure the ohm resistance between the posts on the capacitor it does show 11 m ohms. I'm assuming it related to the internal resistor. If I check for continuity between the posts on the capacitor it shows 0. Resistance between the posts on the the magnetron measure .2 ohms consistent with the documentation Thank you
Answer Mike, Based on the information provided it sounds like an issue with the diode and magnetron. Read More... Answered by AppliancePartsPros.com | Monday, March 25, 2024
