From: Silver Surfer on 29 Sep 2006 19:27 This opener is about 15 years old. The number on the printed circuit board is 14PC366B. Will have to get out the ladder again to get the Craftsman model number. I'll get back with you.

If it blips when you press the button, very likely the power circuitry is OK.
