furnace starting movie - power supply? motherboard?

Erratic operation of a part such as your inducer motor is usually some bad electrical connection or a failing electrical relay or part.
I'd start by verifying that you have a constant 24 VAC at the terminal, which would verify that the thermostat is calling for heat reliably.
Since moving the wires around in the fan comp-artment can cause the inducer motor to switch on, I'd investigate that with some care. Use some tape to hold the door switch in and see if you can identify wire or part starts the inducer motor when it's touched or manipulated.
