The spring inside if broken, the entire weight of the door has no balance. In some cases your opener will begin to rip the opener arm off the top section, especially if the proper Wayne Dalton bracket wasn't installed. If you look closely at the attachment point where the opener arm attaches to the top of the garage door on Wayne Dalton doors, often these pull loose ripping apart the top section of your garage door. A special bracket designed for this attachment resolves this issue. Extra bracing can also be added to increase this vulnerable stress point. We can get the correct Wayne Dalton Bracket for additional cost if needed. The best way to fix this broken Torque Master problem is to convert it into a Torsion Spring setup. I will remove the  Torque Master set up and install a new spring line, tube, end bearing plates, anchor plate, drums, bearing inserts with the correct Torsion Spring rated for the weight of your garage door and upcycled most likely rated for more than 20k cycles.  The cables rarely needs to be replaced unless signs of stretching/fraying is visible. A good quality Torsion Spring should last approximately 10years or more with average use depending on how often you use your garage door.
