Winter Operation and Cold Start

Winter Operation and Cold Start – What to Watch for with an Automatic Gate When the Frost Arrives?

In autumn, everything still works perfectly. The gate opens smoothly, the controller responds to the remote, and the motor hums as it should. Then comes the first morning when the temperature drops to -5°C. And the gate… nothing. Or it just groans, clicks, maybe opens halfway and then stops. Sound familiar? That’s when the question usually comes up: “Is it broken, or is it just cold?”

The Cold Doesn’t Just Strain the Motor Automatic gates face far more challenges during winter. Low temperatures slow down lubricants, put extra stress on mechanical components, while ice and frost can physically obstruct movement. A structure made of metal parts contracts in the cold — only by millimeters, but that’s enough to cause stiffness and prevent smooth operation.

Common Winter Issues:

• The photocell becomes foggy or iced over, causing error signals
• The gate leaf freezes to the ground or to the stopper
• The control unit fails to start because internal capacitors are too cold
• Systems with backup batteries (e.g., 24V motors) have weaker starting performance

What Can You Do as an Installer or User?

1. Use frost-resistant lubricants: Conventional greases and sprays tend to harden in low temperatures. If the manufacturer does not specify a lubrication method, use silicone grease rated for low temperatures or a specialized industrial lubricant.
2. Don’t trap snow or ice under the gate: If the gate is left open while it’s snowing, it may not restart after freezing. Always check the rail area and moving components.
3. Inspect obstacle sensors: Proper photocell operation is essential. If fogging is common, a heated version may be necessary, or at least protective covering to shield it from direct weather exposure.
4. Expect a restart after power outages: In cold conditions, control boards are more sensitive to voltage fluctuations. After a power cut, the system may require a manual restart.
5. Don’t try to force it: If movement is restricted, don’t try to force it by hand, kicking it, or overpowering it with the motor. Breakage and cracks arrive faster than spring.

Winter Preparation — If You’re an Installer

• Check every gate you installed in the autumn, especially new installations
• Make sure the control unit housing is properly sealed and protected from direct cold and moisture
• Confirm that the customer knows how to use the manual release in case of emergency

The good news: Not every gate requires a special winter-rated motor. Most high-quality systems can handle cold weather — if they are installed correctly, properly maintained, and attention is paid to the details.

Summary: Winter gate issues are not unexpected failures — they are predictable conditions you can prepare for. If you take the necessary steps in time, you won’t have to stand freezing in a customer’s driveway on a minus five degree morning while the motor just clicks. Winter isn’t a surprise — only if you fail to plan for it.
