Henderson 800
Garage Door Repairs Kent. A customer had a very noisy Henderson 800 electric garage door opener. Although this electric garage door opener was in excess of 20 years old it still worked well. This type of motor has a steel screw thread that runs in an aluminium rail. Over the years the the scew thread wears away the aluminium and rattles in the channel which makes it very noisy. A special grease packed into the rail reduces the noise considerably and extends the life of the motor.
