1979 Whirlpool LFA7900 shutting off

[duck1850]

Hi everyone, I have a 1979 Whirlpool LFA7900 which recently started to shut itself off in the middle of a regular wash cycle. It doesn't happen each time, and I can turn the power switch back on and it starts operating again. But just yesterday it wouldn't start agitating after filling with water. Eventually it started working by itself. I'm wondering if the control board is going bad. Anyone know how I can access it to take a look? Would appreciate any documentation, manuals or help. Thanks very much.

I have never seen this washer console before. If it were an older mechanical rapid advance type timer, that'd be the problem, but it's probably a control board issue. An overheating capacitor, resistor, etc, can trip the safety.
