Craftsman 13953990D garage door opener Parts

On a Craftsman garage door opener like model 13953990D, the model number is typically printed on a label on the motor unit under a light lens. Check under the front light lens first; many units also place the label under the left lens when you are facing the opener.

Where to look on model 13953990D

We recommend checking these spots in order:

• Under the front light lens on the motor unit
• Under the left light lens (when you are facing the opener from inside the garage)
• On the side opposite the antenna wire (some units place the label there)
• On the motor unit housing near the “Learn” button/diagnostic LED area
• On the back or side panel of the power head (the ceiling-mounted unit)

Quick checklist to find it faster

• Turn the opener lights off and use a flashlight to read the label clearly
• If the lens has a release tab, press it gently and swing the lens down
• Wipe dust off the label; the print is often faint
• Write the model number exactly as shown (for this opener it appears as 139.53990D in the documentation)

On the Craftsman 13953990D, you do not look up a fixed “code” number; it uses a Security+ rolling code that changes with each use. To “figure out the code,” you program (or reprogram) a remote using the LEARN button so the opener and remote sync.

How to program the remote using the LEARN button

1. Press and release the LEARN button on the motor unit; the indicator light stays on for about 30 seconds.
2. Within 30 seconds, press and hold the button on the hand-held remote you want to use.
3. Release the remote button when the opener lights blink (or you hear two clicks if bulbs are not installed).

Quick checklist before you start

• Use a compatible Security+ remote (rolling-code type).
• Stand on a stable ladder; keep clear of the door and rail.
• Make sure the opener has power and the motor unit light works (or listen for clicks).
• If the door will not close, check safety sensor alignment first.

How to erase old remotes (deactivate) and start fresh

If you are trying to remove a lost remote or clear everything:

• Press and hold the LEARN button until the learn indicator light goes out (about 6 seconds).
• Reprogram each remote and any keyless entry you want to keep.

Task	What it does	When to use it
Add a remote	Adds one remote to memory	New remote, extra car remote
Reprogram a remote	Resyncs a remote	Remote stopped working
Erase all codes	Clears all remotes/keyless entries	Lost remote, moving into a new home

Why it matters

Because Security+ uses a rolling code (it changes every time), there is no single code to “read.” Programming through the LEARN button is the correct way to sync remotes and keep the opener secure.

For model-specific programming steps and safety notes, use the owner's manual. To find compatible remotes and other replacement items by model number, search Sears PartsDirect.

To reset a remote on your Craftsman 13953990D garage door opener, erase the opener’s stored remote codes using the Learn button on the motor unit, then reprogram each remote you want to use. This clears all remotes and keyless entries, so plan to add them back right away using the steps in the owner's manual.

Reset (erase) the opener’s remote memory

1. Locate the Learn button on the motor unit.
2. Press and hold Learn until the learn indicator light goes out (about 6 seconds).
3. Release the button; the opener memory is now cleared.

What gets erased

• All programmed handheld remotes
• Any keyless entry keypad codes (if used)
• Any additional transmitters previously added

Reprogram a remote after resetting

Use this method for each remote you want to work with the 13953990D:

• Press and release the Learn button (indicator light stays on for about 30 seconds).
• Within 30 seconds, press and hold the remote button you want to use.
• Release when the opener lights blink (or you hear two clicks if bulbs are not installed).

Quick timing guide

Task	What you do	Typical time
Erase memory	Hold Learn until light goes out	~6 seconds
Add a remote	Press Learn, then press remote button	~30 seconds window

If the door still will not close after programming

A “remote problem” is often a safety sensor issue. If the safety reversing sensors are misaligned or blocked, the door may not close from a remote and the opener lights can flash.

Check these common causes:

• Sensor lenses are dirty or facing away from each other
• One sensor indicator light is off or flickering
• Something is blocking the sensor beam near the floor
• Door travel is binding (door feels heavy or sticks)

For model-specific operating and programming details, follow the Programming section in the owner's manual. For troubleshooting steps and blink patterns, use Craftsman error codes.

Why it matters

Resetting the opener memory is the fastest way to remove lost remotes from the system and restore reliable operation. Reprogramming immediately afterward prevents lockouts and confirms the opener is receiving a clean signal.

To find replacement remotes and other compatible parts by model number, search your 13953990D parts list first, or use Sears PartsDirect for broader model-based part lookup.

In most cases, a 20-year-old garage door opener is not worth repairing because it is beyond the typical 10 to 15 year lifespan and you risk repeat failures in high-wear parts (motor unit, gears, logic board, sensors). For a Craftsman 13953990D, a small, low-cost fix can make sense, but major repairs usually do not.

When repair makes sense (and when it does not)

Repair is usually worth it when:

• The door is properly balanced and moves smoothly by hand.
• The issue is a simple adjustment (travel limits, force settings) or a minor wiring/connection problem.
• The safety sensors are just misaligned or obstructed.
• You only need basic reprogramming for a remote or keyless entry.

Replacement is usually the better choice when:

• The opener struggles, stalls, or makes grinding/clicking noises (common gear or motor unit wear).
• The unit repeatedly fails the safety reverse test.
• You have intermittent operation that points to an aging circuit board.
• You are stacking repairs (one fix after another within a year).

Safety checks we recommend before spending money

Your Craftsman 13953990D manual calls out critical safety testing after adjustments and repairs. Use the owner's manual to follow the exact steps.

• Test the safety reverse monthly.
• Confirm the door reverses on a 1-1/2 in. object (or a 2x4 laid flat).
• Test the photoelectric safety sensors (the door should not close if the beam is blocked).
• Disconnect power before removing covers or servicing internal components.

Quick decision table

Situation	Best next step	Why it matters
Door will not close and lights flash	Sensor alignment and sensor troubleshooting	Prevents unsafe closing and nuisance failures
Door reverses unexpectedly	Force/travel adjustment and safety reverse retest	Avoids damage and injury risk
Loud grinding, no movement	Plan for replacement or major gear/motor repair	High-wear failure, repeat repairs likely
Remote/keypad issues only	Reprogram and replace batteries	Low-cost fix, fast restore

Why it matters

Older openers can still run, but reliability and safety depend on correct adjustment and consistent safety testing. If the opener fails safety tests or needs major internal parts, replacement typically costs less over time than repeated repairs.

For repair help and symptom matching, use Craftsman error codes. For parts lookup by model number, search on Sears PartsDirect.

Common problems on the Craftsman 13953990D garage door opener are safety sensor issues that prevent closing, remote or wall control programming/lockout problems, and drive or motor wear that causes noise or no movement. We use the diagnostic lights and the safety-reverse tests in the owner's manual to pinpoint the cause.

Most common symptoms and what they usually mean

• Door will not close; opener lights blink: safety reversing sensors are misaligned, blocked, or not connected.
• Remote will not run the opener: dead remote battery, lock mode enabled on the wall console, or remote needs programming.
• Door reverses while closing: travel/force settings need adjustment or the door is binding.
• Motor runs but door does not move: worn drive components (chain/belt/trolley) or internal gear wear.
• Intermittent operation: wiring/connection issues at sensors or wall control, or interference affecting the receiver.

Quick checks we recommend first (fast, no parts)

1. Check the safety sensor LEDs: both sensors should be powered and aligned; clear anything breaking the beam.
2. Try closing from the wall control: many openers will not close from a remote when sensors are misaligned, but may close from the wall control.
3. Run the safety-reverse test: the door must reverse when it contacts a 1-1/2 inch object (or a 2x4 laid flat) on the floor.
4. Reprogram the remote/keypad: especially after battery changes or if you want to deactivate an old remote.
5. Listen for clues: grinding, clicking, or humming helps separate drive wear from sensor/control issues.

Blink codes and diagnostics

The motor unit diagnostic LED and the opener light behavior are designed to guide troubleshooting. For Craftsman-specific code patterns and what to check next, use Craftsman error codes.

What you see	What to check first	Typical fix
Lights blink and door will not close	Sensor alignment/obstruction	Align sensors, clean lenses, secure wiring
Remote does nothing	Lock mode, programming, battery	Disable lock mode, reprogram, replace battery
Door reverses during close	Force/travel, door binding	Adjust force/travel, inspect rollers/track
Motor runs, door does not move	Drive/trolley wear	Inspect drive system; replace worn components

Why it matters

Most “opener problems” are actually safety or setup issues. On the 13953990D, misaligned safety sensors can stop the door from closing and trigger blinking lights; correcting alignment restores safe operation and prevents nuisance reversals.
