RoaDor Troubleshooting FAQ

Door Operation Problems:

1. The door is difficult to both close and open.
Tracks are not parallel, or the tracks too close together, or the tracks around the curve are bent in towards each other, or the door is not level, or the side seal is curled under, or the u bolts are not tight enough allowing them to rub against the side seals or the shaft is too long and is jammed between the side angles. The side angles could be bent out towards the side walls making the dimension between the side angle edges appear to be right but are actually too tight at the angle surface in at the door post. In the winter, road grime can fall into the joints, which needs to be pressure washed out.
2. The door closes easily but is difficult to open.
Increase the spring tension.
3. The door opens easily but is difficult to close.
Decrease the spring tension.
4. When opening or closing the door, there is a lot of squeaking.
The spring is too compressed or stretched too far along the shaft and needs to be adjusted.
5. When opening or closing the door, it sounds like a train on tracks.
There is interference between rollers and something in the tracks, or there is a poor track joint between the vertical and horizontal tracks.
6. The door opens 8" and then stalls.
Increase the spring tension or the horizontal track could be poorly installed (less than 90 degrees) with the vertical track. The top panel combination could be too tall. If they are two full 6" panels, another set of rollers and side straps can be added and the screws in the joint between them must be removed.
7. The door rolls well and then it stops short of the sill.
You could have a panel installed backwards.

Latching Down the Door:

8. It is difficult to close the door and latch it.
The Counterbalance Spring needs to be expanded, or the top panel is crushed against the header requiring the top roller brackets to be adjusted upwards.
9. When engaging the latch, the bottom 2 panels pull out towards you.
Adjust the latch sill catch plate for height.
10. When engaging the latch, the door latch must be pulled outwards to engage the sill catch plate.
Adjust the latch sill catch plate back towards the door location.
11. When engaging the latch, the bottom panel pulls to the right.
Cut back the right side of the centre piece of the latch sill catch plate.
12. The door bounces as the truck goes over bumps.
Material needs to be welded to the round steel under the edge of the sill cut out.

Sealing the Door:

13. The door doesn't seal well across the header.
Top seal is deformed, or the top roller brackets need to be adjusted down, or the door is too short for the opening.
14. The door doesn't seal in the middle of the header.
Header is bowed outwards, or the top panel is bowed inwards, or the top roller brackets are not parallel to the tracks, or the door has been hit.
15. The door doesn't seal along the sides.
Side Seals s/b tight against the floor, or the side seals s/b inserted fully, or the side seals should not be curled under when the door is closes, or the side seals are too thick and are not flexible enough to contact the door surface.
16. The door doesn't seal along the sill.
The door needs to be leveled, or the door latch needs to be adjusted (close the gap), or the latch sill catch plate needs adjustment.

Counterbalance Issues:

17. The counterbalance has fallen out of the end bearing brackets.
The shaft is too short, or the cable drum on the driver side when installed was not secured up against the shaft bearing allowing the shaft to act like a drill against the road side wall.
18. The door hangs down too low in the open position.
Increase spring tension, or install door catches. The header size could be too small or the door operator should be raised higher.
19. The spring cannot be adjusted to properly lift the door.
The spring could be incorrect for your application.

Cable Issues:

20. The cables keep coming off of the drums.
The shaft is too long, or the drums are on the wrong side, or there is obstructions in the tracks that interfere with the rollers, or the track joint is poor, or one track rubber stop is missing, or the cable drum screws interfere with the roof, or the cable drum adjusting screws are not making good contact with the shaft (corrosion), or screws supporting the horizontal tracks are backing out and interfering with the rollers.
21. The cables keep breaking at the U bolt.
The U bolts are too tight not allowing the cable saddles to move freely back and forth.
22. The cables break in the middle of the cable.
The cable drums have not been pushed up against the shaft brackets and are interfering with the cables.
23. The cable brackets are bent upwards towards the header.
The cables are too short or the spring has not been expanded sufficiently or the top panels are jammed prematurely into the header.

Top Panel Issues:

24. The top panel assembly separated from the door.
The old style top roller brackets are reversed with the nuts facing into the tracks, or the top roller brackets are being interfered with something in the tracks when closing the door or the top panel has been hit. Horizontal tracks with different profiles (not a smooth curve) could be the cause.
25. The top panel hits the drums or spring when opening the door.
The top roller brackets need to be adjusted upwards to release the top panel or the operator is too low or the door is too tall.
26. The top roller bracket arms break.
The arms break because a wrong profile horizontal track has been installed or it could be a door lifted up by a forklift.

Graphics:

24. The door panels are shifting and skew the graphics on the door.
Poor door width dimension, or rollers that don't move freely in or out of the panel, or an error in panel length, or the tracks could be installed against the wall and not flush to door post as ordered could be the problem. Installing roller spacers on either side of the door or shimming the tracks out from the wall may solve the issue if the tracks were installed parallel to each other.

Painting the Door:

28. Can I paint a RoaDor?
Yes you can paint the door but you may require special paint. Dark and primary colors have excessive heat build up which can damage the door. RoaDor has low heat build paints available which can be color matched to any color. Contact us for more information. Always contact RoaDor before painting the door. Failure to do so may invalidate your warranty
29. How do I prepare the PVC surface for painting?
You can use Vinyl Prep and Vinyl Clean, (available from RoaDor) or use watered down Mr. Clean to prep followed with a diluted vinegar and water solution to clean.

Applying Vinyl Graphics:

30. Can I apply vinyl graphics to a RoaDor?
Yes you can apply decals. Avoid large dark colored graphics. If you are in doubt contact RoaDor.
