A garage door motor that hums can be irritating. You press the remote, you hear the motor running, but the door station is not working. More homeowners than a lot of realise find themselves having this problem.
Sometimes it’s just a minor freak out. In others, it could mean an old motor or broken garage door parts. Knowing the potential reasons can help you in determining whether or not you must get repairs done or even a full replacement.
How Do You Tell the Difference Between Echolocation vs Humming Sound?
If your motor is humming, it typically means the opener is getting power. Now however, this is preventing the system from raising the door properly.
The motor makes an effort to function, but the door actuates only slightly or not at all.
This can happen because of:
- Mechanical failures
- Broken components
- Electrical issues
- Poor maintenance
So, now, let’s look at what are all the usual cases?
Broken Garage Door Springs
Garage door springs carry the majority of the weight of the door. Depending on how many springs are broken, the motor may not be strong enough to lift the heavy door by itself.
The opener simply hums while the door barely moves.
Symptoms of a broken spring:
- A loud bang from the garage
- Crooked door movement
- Heavy manual lifting
- Visible gaps in the spring
Damaged springs can be hazardous, so a pro should check the system right away.
Stripped Motor Gears
There are plastic or metal gears inside of the garage door opener that assists in the movement of the door. These gears are used on a daily basis, and therefore, wear down over time.
All worn gears make the motor run but the opener can’t pull the door up.
This is one of the most common reasons homeowners require garage door motor repairs.
Locked or Jammed Door
The motor itself sometimes is not the problem at all. The garage door itself can be stuck.
Possible causes include:
- Bent tracks
- Dirt build up
- Obstructions in the rollers
- Manual lock accidentally engaged
A slight blockage can prevent it from moving, leaving the motor humming away.
You will take a look at the tracks and rollers for visible damage.
Faulty Capacitor
It helps in starting the motor, with capacitor connected. When this fails, the opener may only hum, but will not have enough power to fully operate the unit.
A damaged capacitor often causes:
- Weak motor performance
- Intermittent opening
- Slow movement
- Complete opener failure
Fortunately, in most cases technicians can repair this while performing the garage door motor at the garage door service.
Motor Burnout
Older garage door openers have a limited lifespan. If the internal damage causes the motor to overheat, it may hum but not rotate.
Other factors that can decrease the lifespan of a motor include frequent use, age, and failure to perform maintenance checks on the device.
A garage door motor replacement is advisable when repairs are no longer cost-effective.
How to Avoid Garage Door Motor Issues?
By servicing regularly, you would be able to prevent break down from encountering all of a sudden.
Simple maintenance steps include:
- Lubricating moving parts
- Checking springs and rollers
- Cleaning the tracks
- Testing the opener regularly
- Scheduling annual inspections
Preventative care usually prolongs the lifespan of both the door and the motor.
