What to check first
Check power first. Is there a light or sound from the motor unit when you press the remote? If there is nothing at all, check the breaker that feeds the gate motor before assuming the motor itself has failed.
Change or check the remote's battery next, and try a second remote if you have one. A flat battery produces exactly the same "nothing happens" symptom as a dead motor, and costs nothing to rule out.
Look at the gate's path for anything blocking it, and check whether a sensor beam — often a small box on either side of the gate opening — is aligned and unobstructed. Many auto-gate motors refuse to move at all if they think something is in the way, which can look like the motor has failed when it is actually working correctly.
This guide covers the motor. If the real problem is a manual bolt on the gate that will not slot or retract properly, that is a separate, non-motor issue — HDB's own home-care guidance for gates covers that case.
The likely causes, in order
Power — the breaker or the remote battery (most common). The most likely cause is power — either the motor's power supply has tripped at the breaker, or the remote's battery is flat — since both produce the exact same symptom of a gate that simply does not respond. Safe check: the breaker and battery checks above; both are safe and free.
A blocked sensor or obstruction. The second likely cause is a blocked safety sensor or obstruction in the gate's path, since most auto-gate motors are built to stop or refuse to move if the sensor beam is broken or something is in the way. Safe check: clear the gate's path and check the sensor alignment; do not force the gate through an obstruction.
A fault in the motor or control board. The third cause is a fault in the motor or control board itself — a burnt-out motor, a tripped internal fuse, or a control board that has failed — which is the most expensive of the three and the one a technician should confirm last. Safe check: none beyond confirming power reaches the unit; opening the motor casing is not a DIY step.
When to call, and how urgently
Do not force a gate that is stuck halfway open or closed, and do not bypass a safety sensor to get it moving. A motor that stalls against an obstruction can be damaged further by repeated attempts to force it through. Do not open the motor unit or its wiring yourself. An auto-gate motor runs on mains power, and opening the casing on a live unit is electrical work, not gate work — that is for a provider or a Licensed Electrical Worker, not a homeowner fix.
If the gate can still be opened and closed manually, this is not urgent — use the manual release while you sort out the motor on your own schedule. If the gate is stuck in a position that blocks access, particularly if it opens onto shared corridor space, treat it as more urgent and call the same day.
What it costs
Ask two or three for a written quote instead.
When you ask, describe exactly what you found: whether the motor shows any sign of power, whether you have already tried a fresh remote battery, and whether the gate moves manually. Ask whether the callout fee is credited against the repair, and whether a new motor or control board would be quoted separately from labour.
Ask what brand and model the existing motor is, if you know it — parts availability varies by brand, and that can change both the price and how long the repair takes.
Who to call, and how to judge them
There is no public licensing register for gate and grille repair in Singapore, so a homeowner's own check is limited to business registration. SCDF requires a minimum clear escape passage of 1.2m along a common corridor, which matters if a gate opens onto shared HDB corridor space rather than only your own doorway. Mention this if it applies to your gate.
An ACRA registration confirms the business exists, nothing more. Prefer a provider who asks the power, battery and sensor questions above before quoting a motor replacement sight unseen. What to check before booking: whether the motor has any power at all, whether the remote's battery has been replaced recently, whether anything is blocking the gate's path or the sensor, and whether the gate can still be operated manually.
Frequently asked questions
Why has my gate motor stopped responding to the remote?
A gate motor not working means the automated gate no longer opens or closes on command, from a cause as simple as a flat remote battery to a failed motor unit, and the two look identical from where you are standing with the remote.
What should I check before calling a technician?
The most likely cause is power — either the motor's power supply has tripped at the breaker, or the remote's battery is flat — since both produce the exact same symptom of a gate that simply does not respond. Check the breaker and try a fresh battery first.
Is it safe to force the gate if it's stuck?
Do not force a gate that is stuck halfway open or closed, and do not bypass a safety sensor to get it moving. A motor that stalls against an obstruction can be damaged further by repeated attempts to force it through.
