I have a frigidaire plef398ccc ES 400 last night was heating up then a pop or snap noise then no power to the oven or display. Only the cooktop works.
I've taken the back panels off to look for anything obvious, and have found no wires rubbing metal, or signs or arking.

Keith,

Check the bake and broil element with an ohm meter. One of them may have gone out.

would this account for no display, no clock or anything else?

I couldn't find a wiring diagram for that model and some have an inline fuse between the element and display. So the answer to your question would be, it could.

I checked for resistance , is there a number that its supposed to be at? There is no open in the circuit. Thank you very much for your help.

Sounds like the control board
may be bad. Any burn marks or signs of arching?

No I haven't found any signs of any arcing, or burn marks, and no smell of anything burned. Thank you
