Why Your Craftsman Garage Door Opener Works For One Cycle And Freezes

When a Craftsman garage door opener works for one cycle and freezes, the issue typically falls into one of these categories:

  1. Overheating or internal motor issues
  2. Faulty safety sensors
  3. Limit switch problems
  4. Logic board malfunctions
  5. Inadequate power supply
  6. Mechanical obstructions or wear

Let’s break these down one by one.

1. Motor Overheating or Failing Capacitor

If your garage door opener works once and then stops responding until it’s been sitting idle for a while, you may be dealing with a thermal overload or a capacitor issue.

Symptoms:

  • The unit works fine initially.
  • After one cycle, the opener stops responding.
  • The light stays on or blinks but the motor doesn’t engage.

Solution:

  • Unplug the opener and let it cool for 20-30 minutes.
  • If it works again after cooling, the motor may be overheating.
  • Replacing the motor capacitor is a good first step—it’s relatively inexpensive and a common failure point in Craftsman openers.

2. Faulty or Misaligned Safety Sensors

Safety sensors are installed near the base of the garage door to prevent it from closing when something is in the way. When misaligned, dirty, or faulty, they can cause erratic behavior.

Symptoms:

  • Door opens, but doesn’t close again.
  • Blinking lights on the motor housing.
  • Must hold the wall button down to close the door.

Solution:

  • Check the alignment of the sensors—they should face each other directly.
  • Clean the lenses with a soft cloth.
  • Make sure there’s no debris blocking the beam.
  • Replace the sensor if the indicator light does not turn on.

3. Limit Switch Problems

Limit switches tell the opener when to stop the door’s movement. If these are incorrectly set or malfunctioning, the door may appear to “freeze” after a cycle.

Symptoms:

  • Door opens but stops short or slams shut.
  • Motor runs but the door doesn’t move.
  • Freezes in mid-cycle or doesn’t reverse.

Solution:

  • Locate the limit switch screws (often on the side of the opener’s housing).
  • Adjust slightly using a screwdriver—clockwise to increase distance, counterclockwise to reduce.
  • Test after each adjustment.

4. Logic Board Malfunction

The logic board is the brain of your Craftsman garage door opener. If your opener works once and then locks up, the logic board may be glitching or failing entirely.

Symptoms:

  • Door responds inconsistently.
  • Remote stops working after one use.
  • Opener beeps or flashes lights without explanation.

Solution:

  • Power cycle the unit (unplug and plug back in).
  • If the issue persists, the logic board may need to be replaced.
  • Replacement boards are available online, or through Sears PartsDirect.

5. Power Supply Issues

If your opener seems to lose power or behaves oddly after a single cycle, make sure your power supply is steady and sufficient.

Symptoms:

  • Opener resets randomly.
  • Lights flicker during operation.
  • Tripping circuit breakers.

Solution:

  • Ensure the outlet is grounded and not shared with high-load appliances.
  • Use a surge protector.
  • Have an electrician test the line voltage if problems continue.

6. Mechanical Obstruction or Track Damage

Sometimes, the issue isn’t electrical at all. If the door catches, binds, or struggles at certain points, it can trigger the opener to stop functioning.

Symptoms:

  • Loud grinding noises.
  • Uneven door movement.
  • Tracks bent or rollers jammed.

Solution:

  • Inspect tracks and rollers for damage or debris.
  • Lubricate all moving parts with garage door lubricant (not WD-40).
  • Replace worn rollers or bent track sections.
