Question about Microwave Ovens
Sadly, we hear of this over and over.
This is due to a defective or loose magnetron causing electrical interference and disruption in the control circuit board.
If your magnetron was recently replaced, it may have loose mounting nuts or bolts or maybe the wire mesh RF gasket was not installed or got pinched.
It may also need a new high-voltage diode and stirrer, and the cavity may be affected.
If you or someone you know decide to look into it, we have critical information on safety, disassembly and door switches at our site, and our link is at our listing here on FixYa.
There should also be a "mini-manual" hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting.
You can find helpful exploded view diagrams and order parts by entering your full model number here.
If it's within the magnetron portion of the warranty (usually 5-9 years) but out of the original full warranty (usually 1 year), then your manufacturer will cover the part cost, but not the cost to visit you or the labor charge to do the work.
They may send you a replacement magnetron. GE Customer Service is here.
