Question about Microwave Ovens
About half the time the oven stops after about 2 seconds. The clock also resets to 12:00 so we set the clock. Sometimes it works fine for a couple days and sometimes the problem will happen several times in a row.
GE JES1136 Countertop Microwave Oven Similar to mdambros, the microwave (GE JES1136) may run for a few seconds (up to 30 or so) then acts like the breaker has popped. After a few seconds, the display shows PF. If I set the clock, it may remain for a few minutes, then it again acts like the microwave has been unplugged (interior light won't come on, no response on touch pad). Unplugging the unit and then plugging it in results in PF and then a brief period of operation.
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.
Details are in their bulletin here. Even if your model is not on the list, the same problem can occur, requiring a kit. The parts kit is similar to this one.
(Your model may use a different kit - this is shown for illustration purposes only).
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 even send you a replacement magnetron. GE Customer Service is here.

the "Stop" button on the microwave to
reset the digital display to the clock setting.
2) Push the
"Clock" button once. Locate the "Hour" button and
press it once for each hour of time. For example, if the current time
is 5:15 p.m., press the Hour button five times.
the "Minute" button to set the second half of the time. For
the example above, you would press the Minute button 15 times to set
a time of 5:15 p.m.
