This fan shares a single GFI circuit with two other bathrooms. The fan in this bathroom stopped working. I removed it and pluged it into an outlet and it works fine. Measuring the voltage present at the in-ceiling recepticle that shoud power it, I find approx 66 volts or one half of what I expected. What gives?

Any/all suggestions appreciated.

Where did you measure the voltage. Hot to neutral. Try hot to ground and neutral to ground. I suspect on open neutral.

Joed: I'm guessing hot to ground (black to white). My mesurement was between the black and white leads which terminated in the two pin plug where the fan plugs in.

When I plug the fan into any other outlet it works fine.

Even so, you've got me thinking that perhaps the ground is open therefore only one half of each AC wave is being measured. Perhaps a good test would be to measure between the white lead at the fan plug and any other black in the switch box for the fan. If I get 120 or so, your suggestion of an open ground would be right.

Thanks for your reply.
