Product review (5 stars): Just what I needed at 1/3 the OEM price!
My 13 year old GE JEM25 oven dropped dead quite suddenly, and some troubleshooting pointed to the magnetron. I was pretty discouraged when I found that the OEM part was $153, or about 65% of what the whole oven cost. Some internet scrounging got me here, and I took a chance on the 10QBP0230. It got here in 3 days and was a perfect fit. Better still, my oven works again, and for 1/3 the cost of the OEM magnetron.

One word of caution -  the photo shown for the 10QBP0230 is not correct. The HV connections are actually in a single oval shaped plastic housing and not the two round, separated housings shown.
