Craftsman Garage Door Opener
I have a 1/2HP Craftsman garage door opener. When I first installed it, the two electric bulbs kept burning out. So I discontinued using one of the bulbs, and it seemed to last for quite a while that way. However, lately the one bulb keeps burning out as soon as I change it. It doesn't make any difference which side I have it on. I was told to buy a heavy duty bulb for garage doors which I did. It went down one time and then blew the bulb out. Any suggestions please would be greatly appreciated.
