Using the neutral for grounding was allowed by the NEC before 1996. When you run the 4th wire be sure you lift the bonding jumper in the range.

It's interesting that Telsa says the POCO did not turn off the disconnect before swapping meters.

Here the meter tech will not come in the house to do that, the homeowner is responsible power off and on.

IIRC the last time they swapped mine a few years ago
(government required random customer meter accuracy check) I had a letter in my mailbox giving me 24 hours notice to turn the breakers off to anything that could get damaged by a spike if I was not home to kill the main disconnect when the tech showed up to swap meters.

Out here, the MAIN is in the all-in-one...

Hardwareguy nailed one problem: the highest amperage trace of solder to relay-3 was impaired. The extra resistance caused the coils to slug along, starved for current.

This was easily fixed with fresh solder, rosin-core.

The MOV's were both bad.

All other measurements came in within tolerances.

However, the low-voltage brain at the front is touchy and so the display fades in and out. Yet functionality has been restored.

The first time through I was going slow: I HATE collateral damage.

Subsequently my speed picked up such that I could jump all over it in no time.

You'd think the industry would establish frame sizes for such ovens. However, dimensional creep means that getting a new built-in style oven to fit your cabinet is problematic.

I guess they figure if the oven goes it's time for a complete kitchen makeover.
