Anderson tandem roller

Greetings. I have Anderson sliding doors in a house built in 1987. I assume that the doors are about the same age. I want to replace the tandem rollers on one of the doors, and I'm writing to make sure that I buy the right part. If I'm reading correctly, it appears that just about all Anderson sliding doors use the same tandem roller: Product Code: 81-128. Is that true? Thanks very much.

Hi, Dave, and thanks for your prompt reply. Based on some Andersen literature I've found, I'm pretty sure that the doors are what Andersen calls Perma-Shield Gliding Doors (1982 to Present) and that 81-128 is the roller part. Because replacing the rollers means removing both the stationary door and the operating door, my inclination is to purchase 81-128 and once I've received it to remove the doors. As long as I can return the part if it proves to be the wrong one, I'd like to take that route. Is that okay? Thanks.

Greetings. Thank you for your reply and the prompt shipment of replacement rollers for my Andersen sliding door. A carpenter and I were set to do the work today when we encountered an unexpected problem: the stationary door seems to be held in place by screws that appear to go down from the bottom panel of the stationary door into the threshold and are not easily accessible. Are we right in thinking that we'll have to remove the screws to remove the door, and if so, will we need to take out the plastic glazing and then the glass to get to the screws? Thanks very much.

Thanks, Dave. I do see a piece of wood trim, and behind it a plastic piece. The plastic piece appears to be part of the door assembly and is screwed on to a top wooden piece (perhaps what you're calling the header?). Am I right in understanding that you're suggesting that we remove the piece of wood trim and the plastic piece and then we'll have enough clearance to remove the door? Thank you.

Thank you, Dave. We'll give that a try and let you know the results.

Dave, you were exactly right, and we were able to install the replacement rollers with little difficulty. Unfortunately, the door is still hard to slide--probably because it is tight in the opening. Is there something we can do to increase the amount of room it has? At this point, the rollers are in the lowest position and can't be adjusted higher. Many thanks for all your help.

Thanks for the info, Dave. Given that the door is probably 23 years old and isn't working properly anyway, I imagine that the warranty doesn't matter much, if it's even still in force. I'll show the carpenter your message and follow up from there.
