Riddle me this...
I have a fan/light combo unit controlled by a standard toggle wall switch. The unit is well over 20 years old.
4 position pull chain for fan - high, medium, low, off 4 position pull chain for 4 bulb fixture - 2 on - 2 off, swap the offs for ons, all 4 on, off.Here's the problem:
If all four lights are off, the unit makes a single POP when I throw the wall switch to the off position. The sound comes from the unit, not the switch.
If any of of the lights are on, I do not hear the POP when I throw the switch.
The position of the fan chain does not appear to matter. Regardless of what speed the fan is running at (including off) the POP only occurs when all four lights are off.
Since there is no current flowing in the light portion of the unit with the light chain in the off postion, why would it pop when power is cut off?
