Question about GE Spacemaker JVM1640SJ Microwave Oven
I am an a/c technition so i'm a verry good trouble shooter but I've never worked on a microwave.I have power coming to the micro and the fuse behind the display has continuity.But all displays are dead and nothig works.Can someone please tell me where to start troubleshooting.
Hi, You may want to try to check/troubleshoot the PCB underneath the display/control panel. The mains do supply two circuitries: the heavy load and the electronics. In some units, they have a standard transformer while in others an SMPS that supplies the +5 (and sometimes +12 or higher) voltage. This powers the electronics which includes a microcontroller, timer, relay drivers and display panel. Trace the transformer/SMPS and look for any fusible link, secondary fuse or surface mounted fuse. More often than not, there are also standard components along the way like bride diode, diode, filter capacitor and regulator IC. Check for VDC input and output of power components. Hope this gives you an idea, Pls post again how things turn up or if you need further information. Good luck and kind regards.
