Sliding glass door is hard to open

What can I put on my sliding glass door to make it open easier? My husband has already put WD 40 on it and it is still hard to open?

 

Have you adjusted the rollers?

 

Adjusting the rollers will help if the door is rubbing on the bottom. You might want to remove the door and check the rollers. The bearing may be worn or gone.

 

What johnam said, plus one step farther!!

If the GUIDE for the rollers is shot, a 'snap cap' might salvage it for you. But if this has been going on for too many years, then replacing the slider might be your only option.

 

Thanks for the help. I will have my husband take a look at this.

 

What are the steps involved in adjusting the rollers and how do you remove the door to check if they are damaged?

 

Most doors ( older ones ) you'll need a #2 philips screw driver , your see a hole at the bottom side ( both sides ) clock wise raises, counter clockwise lowers. On some newer ( and really old doors ) on the inside face of the door at the bottom, there is an adjustment there. adjust same way.

If the door is really really old your see an adjustment on the bottom face and a star looking thing with a screw in it, remove the screw, adjust and replace screw.

Note it is eaiser to adjust the door if you have it raised a bit, to keep the weight off the rollers.

To check the rollers, lower them all the way down, lift the door pull bottom out. If you have a header sag preventing you from pulling the bottom out, find the highest point in the opening , use 2 thin prybars, place them under the wheels, step on the prybars, ( forcing the doors up ) and pull the bottom out.

If you still have problems bottle jack and 2x4 time, ask if needed, Me or someone else will clue you in on what to do with it.
