We had a power surge that took out a few applicances. The unit is completely dead, no lights on the display.

I replaced the fuse, That didn't fix it. The flame sensor is good (0 ohms across it), all of the door interlock switches are good. The only thing left I think is the smart board (main PCB), anything else I should check before I replace it?

There are two more thermal fuses in your microwave: the magnetron TCO and the cavity TCO.

Also make sure there is 120V from the power outlet.

If you need more accurate advises, post the complete model number of the microwave.

Gene.

P.S. It suppose to be an envelope with the wiring diagram inside the microwave.

Thanks Gene,

yes there is 120v coming into the unit. The model # is JE2160SF001

yes there is an envelope with schematic and basic troubleshooting advice. I'll take a look for the other thermal fuses you mention. I didn't see them before on the wiring diagram.

Keep me updated, please.

Turns out that it was infact the main PCB, once I pulled it off it was obvious. The back of the circuit board was fried in one spot.

[Gene]

Just in case if you are going to fix it - the part number for the main PCB is AP3205428

I have the same microwave with a similar problem. We have replaced the fuse through a repairman ($100) and the unit died two days later. The repairman says it will probably keep happening and I should consider buying a new unit (built in cost's $1100). we replaced the main mother board two years ago for $250. Should I bite the bullet and replace or or do you think I can do it myself for $100 and replace the mother board again?

If I do replace it, do you have any suggestions for a more dependable built in unit to replace this GE Profile JE2160sf001? Thanks!

Kevin,

Did a repairman tell you why the fuse keeps blow?

Did you notice how the fuse died?

Did it happen while the microwave was cooking or you just pressed the Start button?

Gene,

All he said was that he has seen others do the same thing and they just keep replacing fuses and mother boards. Thats when he recomended a new unit.

We have never seen the fuse blow and it doesn't happen while cooking. The last two times there has been a error light flashing which clears when you hit clear. Within a day the unit is dead.

Which error code was flashing?
