If the plug to your garage door opener is hard to reach or hard-wired, turn off the breaker that controls it in your circuit box.
Make sure that there is no debris left in your tracks that the rollers can get stuck on. Use an automotive brake cleaner to loosen and wash away grime.
Garage door grease will typically come in an aerosol or spray can. Oil is susceptible to dirt and dust buildup and is more likely to drip than garage door grease or lube. Read the label to make sure that the grease that you are using is appropriate for your doors.
Any exposed ball bearings must be thoroughly lubricated. Don’t spray any lubricant on nylon rollers.
You will most likely need a step ladder to reach the springs and bearing plates. If your springs are making noises, you need to grease your springs. If your springs are damaged or bent, have them replaced before moving on.
The chain comes with a natural protectant on it that makes it so that you don’t have to grease it regularly. Spraying the bottom of the rail doesn’t do anything. Consult the owner’s manual to see how to lubricate and maintain your specific garage door opener.
