I do not see a light switch on the control. There are only two 18 Ga wires
going to the unit. However I will check the ground on the unit as I would
almost bet the ground is not connected in the outlet as this is an old house
when I go over to the place after work today.

Does this unit's wall button include an on/off switch for the light, is it
off? Check for a bad ground at the ceiling or wall outlet.
You can get the manual for about 5 bucks at http://www3.sears.com

I just bought a house that has a Sears/Craftsman Garage door opener model
139.536006. The light on the unit will not turn off. Any one have a
service manual or know what would cause this. I did not get an owners
manual with it.

Thanks,

Larry
