Roller garage doors provide your business with a high level of security and typically last for years before requiring expert attention. However, issues can develop over time. The motor is one part that might start to show signs of wear, including overheating.
When the motor starts to overheat, your garage door opener will usually stop working completely for a short time as thermal overload features kick in to prevent further issues, and that can become a real inconvenience. More importantly, an overheating motor can soon fail completely, so you'll want to have the issue addressed by a professional as soon as possible.
With that in mind, here are just five common reasons for an overheating garage roller door motor.
1. Heavy Use in Hot Weather
Roller door motors often start to overheat when they are used frequently during a short period since heat is created whenever it moves your garage door up or down. When that heat isn't allowed to dissipate, overheating can result. This is more likely during periods of hotter weather, especially if the inside of your garage has no climate control system.
2. Improper Maintenance
Garage door motors can become contaminated by dust and debris over time, but this should be controlled through regular maintenance. If you don't regularly apply lubrication or clean the moving parts of your garage door to eliminate contaminants, the motor will need to work harder. As a result, it will often start to overheat.
3. Damaged Parts
It's hard to damage your garage door motor without it failing completely, so overheating often occurs due to damage to other parts of the system. If part of your roller door becomes dented or knocked out of alignment, your motor will have to work harder and will often overheat. This is another issue that tends to be exacerbated by high temperatures since heat expansion can make such matters worse.
4. Blown Starting Capacitor
When you start up a garage door opener, the starting capacitor energizes the motor and builds up enough torque to open or close the door. If the starting capacitor ever goes bad, excess power may cause the motor to overheat — in fact, you might even see smoke starting to come from the system.
5. Poor Wiring
If your roller garage door motor starts to overheat sooner after installation, bad wiring is a likely culprit. Poor connections often lead to overheating since a high wattage will be generated over a small area. Any wiring issues can be a major safety concern, so this is a problem that should be addressed without delay.
