My bathroom fan stopped a couple years ago. Checking it out and if I bypassed the circuit board with the switches the fan worked fine. So I got a new circuit board and it worked for about a year. Now it is flakey. Sometimes it works, sometimes not. SOmetimes it works for a while then stops. I think the fan itself is fine. Thinking of skipping the circuit board and getting a 3 speed 12v mechanical switch and using that in it's place. Thoughts?

A simple fix is usually your best option.

I don't think a simple fan really needs a circuit board. If you can bypass it. Do it.

What is the function(s) of the circuit board. Knowing that is the key to making a sound decision.

I would start with contact cleaner on the switch/PCB.
Without more info, I would assume that the circuit board is just a mechanical switch with resistors for different speeds.
Is this a model with rain sensor or automatic lift?
Have you checked the plunger switch?
