Garage Door Motor Not Responding?
Total silence, humming without movement, or hopeful clicking — each opener symptom has its own short diagnosis list. All major brands repaired across Perth.
Quick Answer
An unresponsive opener nearly always traces to one of five things: no power reaching it (breaker or outlet), a start capacitor that's died (the tell-tale hum), a cooked logic board, a stripped drive gear (motor spins, door stays put), or a unit that's simply worn out. Repairing the opener runs $380–$490; a new one supplied and installed is $770–$990. And if you hear humming or clicking, take your finger off the button — that's how windings cook.
Common Causes
No power to the opener
Start at the cheapest fix: a breaker that's tripped on the switchboard, a GPO with no output, or a plug that's walked out.
Failed capacitor
Humming with no motion is the signature of a dead start capacitor — routine to replace on most older openers.
Logic board failure
Surges and years of heat wear out logic boards; the courtesy light can still glow while commands go nowhere.
Stripped drive gear
Motor spinning while the door stays put usually means the nylon drive gear has chewed out — a part swap, not a new opener.
Overload from an unbalanced door
When a spring fades, the door effectively doubles in weight — the opener's thermal cut-out kills the motor to protect it.
End of motor life
An opener's working life is about 10–15 years. Beyond that, brushes and windings fail often enough that a new unit beats repairs.
What You Can Check Safely
Safe to check yourself
- Reset a tripped breaker once — once only; repeat trips mean a fault
- Test the opener's power outlet with another appliance (e.g. a lamp)
- Run the test from the wall control too, not just the remotes
- Report what you hear: nothing at all, a hum, or clicking — each shortens the diagnosis
Do not attempt
- Stop pressing the button on a humming motor — every attempt cooks the windings further
- Keep the motor cover on; capacitors bite even with the power lead out
- If the door feels heavy on the manual release, stop — that's a spring problem, not a motor problem
When to Call a Technician
Call a technician straight away if any of the following apply:
- Humming or clicking from the unit, with zero door movement
- The courtesy light comes on but the motor itself never starts
- Starting attempts trip the switchboard breaker
- You hear the motor run while the door ignores it — a stripped drive gear
- It's past its tenth birthday and faults keep returning
- With the release pulled, the door is too heavy to lift

Frequently Asked Questions
Silence points to supply: breaker, outlet, transformer — or a board that's died. Prove the power first (lamp in the outlet, one breaker reset). Once power is confirmed good, the fault is inside the opener and needs proper diagnosis.
