Why electric gates fail in winter — and how to prevent it

The four ways winter breaks a gate

Cold weather is the busiest season for gate repairs, and it is not bad luck — it is physics. Four failures account for most of what we attend between November and February.

• Flat and failing batteries. A gate's backup battery loses capacity in the cold, and a battery already weak in autumn will not survive a hard frost. This is the single most common winter call-out — the gate works until the first freezing night, then stops.
• Frozen and seized mechanics. Water sitting in a sliding track or around an underground motor freezes, and the gate either will not move or strains the motor trying. Grease stiffens, hinges bind, and rollers drag.
• Triggered safety edges and photocells. Rain, condensation and ice across a safety beam or pressure edge reads as an obstruction, so the gate refuses to close — a fault that looks like a breakage but is the safety system misfiring.
• Wind load on exposed gates. A motor that coped with a heavy ornamental gate in still weather can stall against a winter gale, especially on the exposed rural entrances around Dorking and the Surrey Hills.

The autumn checks that prevent them

Most winter failures are preventable with an hour before the cold sets in. If you do nothing else:

• Test the backup battery now. A battery more than three or four years old should be replaced before winter, not after it strands you. This one check prevents the most common fault.
• Clear drainage around underground motors and tracks. Standing water is what freezes. Keep the track and the motor pit clear of leaves and silt.
• Clean and check the photocells and safety edge. Wipe the lenses, make sure the edge rubber is sound, and confirm nothing sits in the beam.
• Lubricate hinges, rollers and tracks with the right cold-rated grease, so they do not stiffen.

This is exactly what an autumn service covers — see gate servicing and maintenance. The winter-specific checklist is on the pre-December checklist.

When it has already failed

If your gate has already stopped in the cold, the fault maps to a symptom. A gate that won't open is usually power or battery; a gate stuck open or refusing to close is usually a safety device triggered by wet or ice; a gate beeping or clicking is often warning you the battery is on its way out. We prioritise winter call-outs across Surrey — see gate repairs.
