Frigidaire FED355 Electric range. Oven and stove-top in use, heard loud 'Phump', and it all goes dead, clock, lights, etc. Warm plastic aroma. Reset breaker. Range top lights, clock, timer now work.

No fault or error codes.

Can set oven temperature or broiler high/ low, relay clicks, but no heat on either element.

Voltage at elements shows 120v to ground from each leg, but 0 between the two legs.

Also, any sources for diagram to remove board? I've pulled most every panel, sides, top, rear, but can't remove front control panel. Thanks.

A common problem with ranges is the control board relays fry taking out some of the range functionality. I fixed one that just the oven did not work another that everything was dead. I would start here with the range unplugged look at the the control board there are usually several larger plastic covered relays look for damage on the board. since you mentioned the plastic smell it would be a good starting point. I found the parts for 1 range for 50-60$ the self cleaning convention oven was over 200, that was cheap compared to 1300 for a new one. here is a link to a utube video on how to do it. Added, The relays switch both legs of the 240V if 1 leg of the relay fried (the noise and burn smell) you would read 120 to ground from both ends of the element.

In the US, we use 240V and put our neutral midway between. This gives us two "legs", call them L1 and L2, and neutral in the middle between. L1 to neutral is 120V. Neutral to L2 is 120V.

Ovens use 240V for heat (L1 to L2). But they use 120V for the oven light bulb and controls, so they grab that between one leg (say L1) and neutral.

So imagine you have a broken wire in L2. L1 and netutral are good - controls and oven light work. But L2 is bad, so no heat.

That sounds like your symptom.
