Steel-Line Door and Opener Repairs in Perth

What usually fails on Steel-Line doors

1. 1

   Roller door has lost spring tension

   The barrel spring loses a little tension every year. Nothing dramatic happens; the door just gets progressively heavier until the opener is doing work the spring should be doing, and eventually it strains, stalls or trips out.

   Symptom

   Pull the manual release with the door fully closed, then lift the door by hand about a metre and let go. A balanced door holds its position. One that drops or shoots up is out of balance. Do not attempt to wind the spring yourself.

   The repair

   We re-tension the spring to balance the curtain, or replace it if the coils have fatigued or a wind has broken, then reset the opener force.

2. 2

   Smart Series opener stops mid-travel

   These heads use force sensing to detect an obstruction. A stiff guide, a dry axle bearing or a heavy door reads as an obstruction, so the opener stops or reverses part way through a cycle for its own protection.

   Symptom

   Run the door by hand with the release pulled. If it drags, catches or squeals at the same point every time, the door is the problem and the opener is doing its job.

   The repair

   We free up the mechanical fault first, lubricate the guides and bearings, then reset the force and limit settings so the opener is not masking a door problem.

3. 3

   Bottom slat and seal damage

   The bottom slat takes every knock, every bumped bin and every bit of driveway grit. Once it bends, the curtain no longer runs square in the guides and the seal stops meeting the concrete.

   Symptom

   Sight along the bottom slat from one side. Any bow, kink or split in the rubber will be obvious. Look for daylight under the closed door and for water marks on the garage floor after rain.

   The repair

   We straighten or replace the bottom slat, fit a new seal to suit the floor profile and re-set the closing limit so the door seats without crushing the rubber.

4. 4

   Remote or wall control not responding

   Steel-Line openers are supplied with rolling-code handsets paired to the head. Batteries flatten, handsets get dropped, and the two-core wire to the wall button gets pinched behind shelving or nicked by a nail.

   Symptom

   Try the handset from a metre away and then from the driveway. A remote that only works up close usually has a weak battery or a failing receiver. If the wall button is dead too, suspect the wiring or the head.

   The repair

   We replace batteries and handsets, re-pair the codes, and run new wall-control cable where the original has been damaged.

5. 5

   Curtain rubbing or grinding in the guides

   Guides get pushed out of line when someone clips them with a car or a trailer, and limestone dust packs into the channel. The curtain then binds, wears its edges and puts extra load on the opener.

   Symptom

   Look for shiny wear marks on the curtain edges and paint scraped off inside the guides. Check both guides are still hard against the wall with all fixings tight.

   The repair

   We re-align and re-fix the guides, clear and lubricate the channels, and dress or replace curtain edges that have worn thin.
