Question about Sears Craftsman LiftMaster Chamberlain Garage Door Opener Wireless Keypad Model 976LM Security+
You need to check your door springs and the drive gear. You may have a broken spring or your drive gear may be stripped. Remove the cover from the motor unit and it will be obvious if the gear is bad.

Dishwashers use Bi-Metal strip to
allow the dispenser to open/close. This strip when heat up causes the soap door
spring to open up the dispenser. If this strip is not heated doesn't allow the
door to open. The strip may not be getting 120V or maybe disconnected. Newer
(plastic liner) dishwashers use a wax motor to open the soap dispenser. The
plunger inside the wax motor slowly moves and pushes the plunger and door
open. And, if this wax motor doesn't receive 120 volts, then it'll not work.
Please check the voltage to the wax motor/Bi-metal strip; also inspect the
connections to these.
Hope this helps...
