Up and Down Garage Doors diagnoses and repairs garage door openers that click but won’t move across Metro Vancouver BC, using stocked parts and local knowledge of coastal humidity wear on chains, belts, and logic boards.
Why Your Opener Clicks But the Door Stays Put
The click you hear is usually the relay on the logic board firing, but the motor never engages. In Metro Vancouver’s damp climate, moisture creeps into the opener housing and corrodes solder joints on the control board — especially on older units mounted in uninsulated garages. A seized trolley carriage, stripped nylon drive gear, or broken chain sprocket will also produce a single click followed by silence. We test voltage at the motor terminals first, then isolate whether the fault is the board, the capacitor, or the mechanical drive train.
Common Failure Points We See in Richmond and Delta Homes
Corroded logic board relays
Coastal salt-laden air accelerates oxidation on the relay contacts. The board clicks but cannot pass current to the motor. We replace the board with a current-revision part that conforms to the newer conformal-coating spec.
Stripped nylon drive gear inside the motor unit
Chain-drive openers in older Steveston and East Richmond ranches often run dry because homeowners rarely lubricate the rail. The gear teeth shear off, the motor spins freely, and the trolley never moves. We install a hardened-steel gear kit and re-grease the rail with a low-temperature synthetic grease built for our winters.
Broken trolley carriage or carriage bolt
Belt-drive units in newer South Surrey and Tsawwassen builds use a plastic carriage that cracks after years of daily cycles. The opener runs but the door stays closed. We carry OEM carriage assemblies for LiftMaster 8500/8550 and Chamberlain B970 series.
How We Diagnose on the First Visit
- Disconnect the opener from the door and run the motor solo — confirms motor and board health.
- Check door balance manually; a heavy, unbalanced door masks itself as an opener fault.
- Measure capacitor ESR and motor winding resistance with a multimeter.
- Inspect the safety-reverse sensor alignment; misaligned sensors on sun-warped tracks can inhibit movement while still allowing the relay to click.
FAQ
Is it safe to pull the emergency release and operate the door manually?
Yes, but only if the door is balanced. If the springs are worn or a cable is frayed, the door can crash down. We verify spring tension before advising manual operation.
Can I just replace the logic board myself?
Boards require programming to the remote frequencies and travel limits. A misprogrammed board can cause the door to reverse mid-cycle or fail to reverse on obstruction — a safety hazard. We program the remote and travel limits per the manufacturer’s specs and verify the obstruction-reversal safety test before leaving.
Why does the opener work fine in summer but click in winter?
Cold temperatures thicken old grease and contract metal, increasing drag on the trolley. Combined with a weak capacitor, the motor cannot overcome the added resistance. We flush the rail and install fresh synthetic grease.
Do you carry parts for older Craftsman and Master Mechanic models?
We stock gears, trolleys, and logic boards for most Chamberlain-manufactured brands sold in Canadian big-box stores since the 1990s. If a part is discontinued, we retrofit a current-production opener that fits the existing bracket pattern.
What if the door is off-track instead of the opener?
An off-track door will bind and prevent movement. The opener clicks because the motor stalls against the bind. We realign tracks, replace rollers, and reset the opener limits in the same visit.
