  • ...the light, fan, timer is working fine , the other day the thing just stopped turning on....Its A ge jvm1790 sk 01 convection oven....any ideas???

  • @mule5150 You should check to see if it is still under warranty. With traditional microwaves the common problem is the HV capacitor or the Diode is bad. A bad power relay will not supply power to the transformer. If it uses Inverting technoilogy, I'm not familiar with them. -MrFixit

  • If your control panel is working, the light and time are functional, could the fuse still be bad??.....let me know ..thanks ...

  • @mule5150 No. If the fuse was bad nothing would work. Something is wrong on the high voltage side. It can be anything from the transformer not getting power to a bad magnatron. Watch my 'troubleshoot microwave' playlist from our channel to see if transformer is geting power. 'Testing capacitors and diodes' videos will help check the those 2 components. In most cases it was either the capacitor or the diode that was bad. -MrFixit

  • ...Thanks for the reply...Its not under warranty any more..maybe I'll just take it down to the range, and use it for target practice.................

  • @TheRandyrog If there is no power to the microwave, you'll need to remove the cover and check the fuse and replace if blown with same rating fuse. If it blows again, something is wrong and I'll help you to find the problem. -MrFixit

  • @Eric101point101 This is one of our early videos before I found the correct Audio adapter for the video cam. -MrFixit
