Trace that circuit. It may also go through some thermally

Heaters are open circuit it doesn't start when you push the start button,
can't be the heaters. - GWE

It depends on how things are wired. I agree that they *should*
be wired so the start button is only in parallel with the hold contacts
on the contactor, but I've seen things mis (or stupidly) wired many
times before.

Good Luck,
