Open the canopy, the cover up against the ceiling. The electrical box is there with the wires coming up from the wall switch. Give all the wires a tug on the wire nuts to make sure they are tight and twist the wire nut to tighten. Check pull chain switch and see if it feels solid. This would be the first steps do take here.
OK, I have done that. Only getting 84 VAC between the hot and common going to the light. Guessing some kind of short in the motor windings?
I want you to do two checks for me
Check the voltage at the fan from black to ground
then black to white neutral
ok. hold on
see what you get on the two tests?
Getting about 80 vac
Do both tests
one is black to ground
one is black to white neutral
TWO readings please
black to white
black to bare copper
OK, getting about 79 to 80 vac on both
Ok, this means the black hot wire is not getting good connection back towards the wall switch
Check the connections at the wall switch and voltage coming into the switch and leaving...what voltage is there?
See it there is 120 coming into the switch
120 vac. Could it possibly be a motor short or something else in the fan head?
Then what it is leaving on the red and black wires going to fan
and it's 80 volts up at the fan ceiling box coming in?
black and red are 80 in the ceiling box?
120 at switch?
I'm getting 7.8 to 8 vac at ONLY 1 switch setting. The rest are zero. I assume that is the highest speed setting.
Ok you told me it was 120 leaving so it's at the switch that is the problem
so it's 8 volts leaving the switch?
you have 120 coming in though?
No, only 80 coming in but I have not pulled the fan off the wall. The 80 is just at the black and white in the junction box bellow the fan motor. Sounds like maybe the wire nut on the black above the fan in the ceiling maybe loose?
Wait a minute
You said there is only 8 volts down at the switch?
Right up a above you said "
"I'm getting 7.8 to 8 vac at ONLY 1 switch setting. The rest are zero. I assume that is the highest speed setting."
Sorry, that's out of the switch going to the fan. The red and black wires coming out of the fan switch going to the fan motor.
at the wall or up in the fan?
Sorry I'm loosing track where the voltage is at what location
In the ceiling box is there 120 volts coming into the ceiling box?
Then it's lost to 8 volts inside the fan switch up inside the fan?
Oops sorry, didn't scroll down far enough.
Let me check the voltage coming to the fan at the ceiling. Give me a minute.
OK getting 78-80 vac accross black and white coming out of the ceiling still connected to the fan. Must be the wall switch right?
Let me check that again
yes it sounds like it
go back to the wall switch and verify what is coming in
and what is going up top fan out of the switch
important here to find which way to proceed
Check in and then out of wall switch
to white wire
black to white and red to white
OK think I may have found it. I'm getting a full 120 vac on the in side of switch to white. When I turn the switch on and check the out side to white I'm only getting 90 or so. Probably bad wall switch? Probably 40 years old.
Is it just a regular switch? It's not a dimmer is it?
If it's a switch it's bad
You can bypass the switch and see if the fan and lights work...? Turn off the power to do this
use a circuit breaker
Yeah, just a regular switch Let me try to bypass the switch
Yes try that
That was it! First time for me. thanks for the help!
Great we did it!
Glad to help
