I have a problem with my 1/2 horse Craftsman Garage Door Opener that I cannot figure out. My light was out, so I went to change the light bulb but noticed that it wasnt fully turned. I did that, but the light still wouldnt come on. I replaced the bulb and then clicked the opener to turn the light on, but instead IT SPARKED emitted a terrible black smoke and completely fried the light socked and end cap. (DONT WASTE YOUR TIME BY CALLING SEARS OR CRAFTSMAN TECHNICAL SUPPORT). I got all that taken care of with the breaker etc, and took off the end cap and what remained of the light socket. The Door opener doesnt seem to have any effects other then it wont engage. When I click on the opener, it just clicks - goes off - and clicks again. I am not sure if it is my capacitor or what could be the issue. Please HELP!!!
