Are you ready?
First thing to check is control wiring behind the switch and at the air exch. for good contact, but In most cases and I just fix the same problem today, is the bathroom control is toast and will need to be replaced.
You said it works for the rest of the house so has nothing to do with capacitor, anyways dont forget when you open the door of air exch it cuts the power off
Get it? You said (I have an air exchanger that works for the rest of the house, except in the bathroom )
do you have other timer switch it the house ? you could swap one to see if it will work
What brand is the unit?
this will work
control comes with wiring instruction, it will say witch two you will use
take defective switch out the wall and take the 2 wires marked PB PB off the control and put them together, it should start the air exch.
Why does it take you so long to reply?
No, it's the other 2, dont make that mistake, if you look at the links I sent you there is a wiring diagram that shows that clearly.
Yes, I beleive the control you have is no longer available, so never short out the power R C, put the other 2 together
Just to clarify.. if you set the MAIN control ON, does unit work?
That changes everything!!!
At this point it could be many different things.
If you open air exch. can you manually spin the blower wheel? is it seized, hard to turn or all free?
Press in door switch to allow power to unit and try spinning it then and see if tension changes, if not try and locate where hum is coming from
There you go!! and that is a common issue with those units,
You can call the number on link I sent you and proceed in getting a replacement blower assembly kit.
We can resume this issue at that for sure.
