Although all these problem when we come repair a screw drive opener usually the problem will be pretty simple to repair the trolley can be replace at an inexpensive cost depend on the model and our after market trolley gear made from heavy duty metal what will keep it functioning much longer then the factory part as long as you keep with the annually checkouts keep the system balance and most important keep the torsion on the garage door springs balanced. most screw drive openers will brake when the springs are weak and no longer carry the door wight as they should.
Annually maintenance can be done by a garage door professional or even by you if you are the do-it-yourself kind of man/woman, make sure the door is balance ( go up and down straight on both sides ), cables are good ( no visual wear and tear on them and tied when door is close and open ) the springs are balanced ( door stay half open when it’s detached from the opener ) and lubricate it all.
