Tips and Warranties
Garage Door Sensor Alignment Tips
Safety beam sensors for garage door openers need to be aligned and kept
clean for proper operation. If the sensors lights are flashing, the door
will not go down. If they are not lit they may need to be replaced.
Also check the wire connections to make sure they are secure.
Screw Drive Lubrication
Screw drive openers need to be lubricated with Aero Lubriplate at least
twice a year. Do not apply lubricant if the temperature is below 32 degrees.
All garage door remotes have batteries and should be replaced once a
year for maximum performance.
