Product review (1 stars): Worked perfectly....for 6 months!
3 year old GE Profile Microwave stopped heating food. Ordered this part with the high voltage diode. One hour later it was back above the range and heating food!!  The magnetron has a 5 year warranty but would have cost me just as much or more to have a repairman come out.  Happy with the purchase. Saved me from having to replace the entire unit!

Edit 9-22-2017:  Microwave has stopped heating again!  Uggg!!!  This lasted approximately 6 months.  Same issue as before. Likely will not replace it again.
