Fixing a Bi-Fold Door

It is common to have a Bi-Fold door install as a toilet door. It is flexible, space saver and water resistance. After a while 3 to 4 years depend on your usage the Bi-Fold door will become stuck and not easy to fold. Most of the time this is due to the broken roller at the bottom of the door.

Broken Roller

I have been asking around for a replacement part. Unfortunately it is not available. Most hardware stores suggest me to replace the door. I found a quick fix to the problem.


Step 1: Dismantle the door from it frame. 

The door hook at the frame at 4 parts. They are the rollers. 2 are moving and another 2 are fixed. The roller guide is adjustable by a spring. You can push inwards to take the guide off the rail. Do that to all the 4 rollers. Take down the door and lay it down on the floor.


Step 2: Swap the rollers.

All rollers can be pull out from the door and they are all the same. Swap the faulty roller with the ok one (You can swap with the fixed roller). After you done put back the door to it frame. And your door will function as new
