Garage Door Not Closing All the Way
in Colorado Springs, CO
When a garage door stops a few inches above the ground, the safety sensors along the bottom of the track are usually the first thing to check. Colorado Springs winters leave snow and ice near the garage floor, and that debris can block or bump the sensors out of alignment. Leaving a gap at the bottom also drives up heating bills in a home with an attached garage.
Quick Answer
A garage door that will not close fully usually has a misaligned safety sensor or a limit switch set incorrectly. In Colorado Springs, sensors get knocked out of alignment when snow shovels or trash cans bump them in tight garages. A technician will realign the sensors and adjust the close-limit setting on the opener. Get this fixed promptly because a gap at the bottom lets cold air, pests, and snow into the garage.
Telltale Signs
Warning Signs to Watch For
- The door descends and then immediately reverses before hitting the floor
- The opener light blinks a set number of times after the door reverses
- There is a visible gap of two to six inches between the door and the garage floor
- The sensor lights on the side of the track are off or blinking amber
- The door closes fine when you hold the wall button continuously but not otherwise
- The door closes fully in warm weather but not when temperatures drop below freezing
Root Causes
What Causes Garage Door Not Closing All the Way?
Misaligned Safety Sensors
Two sensors sit low on each side of the door track and aim a beam at each other. When the beam is broken or the sensors are pointed even slightly off-axis, the opener thinks something is in the way and reverses the door. In tight Colorado Springs garages, items stored along the wall bump the sensors out of place constantly.
The Fix
Sensor Realignment
A technician repositions both sensors until the indicator lights show solid green and confirms the beam holds steady through several full close cycles. Mounting brackets are tightened so the sensors stay put.
Incorrect Close-Limit Setting
The close-limit switch tells the opener how far down to travel before stopping. If this setting drifts, the opener stops the door before it reaches the floor. This can shift on older openers after a power outage or surge, which are common in Colorado Springs during summer storm season.
The Fix
Close-Limit Adjustment
A technician uses the adjustment screws or digital settings on the opener to increase the close-limit travel distance. The door is tested several times to confirm it seals fully against the floor without straining the motor.
Frozen or Damaged Bottom Seal
The rubber seal along the bottom of the door can freeze to a wet garage floor overnight. Temperatures in Colorado Springs regularly drop into the teens in January and February, and ice bonding the seal to the concrete makes the opener think it hit a solid object and reverse.
The Fix
Bottom Seal Replacement
A technician removes the frozen or cracked seal and installs a new one. A light coat of silicone lubricant on the bottom seal before winter prevents it from bonding to the floor on freezing nights.
