Gear Kit Needed – Heavy Door Stripped Gear on Garage Door Motor

 In blog, Service

Heavy door in Vancouver caused garage door motor / gear to fail.

A gear kit is needed for a customers garage door to discover a constant humming sound from the operator resulting in the door not opening. This problem is fairly common when a garage door is not properly balanced, usually due to lack of maintenance or a seasonal change.  The technician can quickly discover this issue, as white powder / fluff will be leaking out of the garage door motor’s case. Inside the operator the gear has been shredded to bits from the motor.  A damaged gear will cause the operator to output a constant humming sound when the gear is not making contact. A gear can be damaged when the gear assembly is not properly greased during the lifespan of the motor. A gear assembly should be greased every three years to assure that no friction/heat is attained during the lifting and lowering of the garage door.
