Hello,
I have a GE Microwave/Oven combo with Model PT970SR3SS. Oven works fine but microwave recently blows out 20A fuse frequently. First time, I replaced the fuse. It worked for about a week. Then, I replaced capacitor and again it worked for about a week and fuse blows out again. Any idea what could be wrong?
Thanks for your help in advance!
George
Hi,
When does the fuse blow?
Opening the door? Closing the door? Middle of cooking? As soon as you press the start button?

Good morning Jeff,
Thanks for helping! It’s in the middle of cooking. After I replaced fuse, it used to work for one to two weeks without any problems, even if I opened door in the middle of cooking. I even replaced capacitor but still have the same problem. The problem happened last time when I put 3 min. It happened after about 2 min.
Thanks,
George
When the fuse lets go in the middle of cooking makes me think the fuse is actually melting rather then tripping. Same effect, the fuse opens up and we loose power. The fuse holder was the most common reason for me to allow the fuse to heat up and let go.
Your model# shows the original fuse holder linked here is now NLA but the more common noise filter and fuse holder together is still available.
Check the metal ends for any pitting or arc marks. Check the fuse ends for any arc or pitting marks.
If you have enough fuses, you could allow the fuse to blow and immediately touch the fuse to see if it is warm or hot to the touch.
