HELP!! I have an older model Genie (SD9500) garage door opener. Lately, when I either open/close the door, the 2 lights stay lit. (past the normal 5 minute time delay). Do I need a new sequensor board? $45-$50 seems like a lot to turn off two light bulbs! Previous home owner didn't leave a schematic for the opener and the Genie homepage isn't any help.
THANKS in advance,
Jim
