Craftsman 13953918D garage door opener Parts

Your Craftsman garage door opener model number is printed on a label on the motor unit, typically under one of the front light lenses. For model 13953918D, check under the light lens cover and match the number exactly to the label and your paperwork in the owner's manual.

Where to look on the opener (most common spots)

• 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 of the motor unit housing, often opposite the antenna wire
• Near the learn button area (label may be nearby on the housing)

How to confirm you found the right model number

Use this quick checklist so you do not confuse the model number with a serial number or a logic board number.

What you see on the label	What it means	What to do
A number like 139.53918D	Model number	Use it to match parts and instructions
A longer code with letters and numbers	Serial number/date code	Keep for records, but do not use for parts lookup
Frequency notes like 315 MHz	Remote/control system info	Use for remote compatibility and programming

Why it matters

Using the exact model number helps us match the correct Craftsman parts diagrams, remote programming steps (including the learn button process), and safety sensor setup details so the door reverses properly and the opener operates safely.

Next steps once you have the model number

• Compare the label to the cover page of the owner's manual
• If you are troubleshooting, use Craftsman error codes to interpret flashing lights or diagnostic codes
• If you need to order parts, start with the parts list for model 13953918D, or search by model on Sears PartsDirect

Yes; repairing a 20-year-old Craftsman garage door opener like model 13953918D is worth it when the problem is adjustments, sensors, remotes, or routine wear. If the opener needs repeated major repairs or the door hardware is unsafe, replacement is the better value.

Quick decision checklist

• Repair when the opener runs and the door moves smoothly by hand.
• Repair for sensor alignment, force or travel limit adjustments, or remote programming.
• Repair when safety reversal works consistently after proper adjustment and testing.
• Replace when the opener strains, stalls, or needs frequent service to keep working.
• Replace when safety reversal cannot be made reliable.

What to check first on model 13953918D

Use the same safety and adjustment steps the manual calls out.

• Door balance test: pull the emergency release and lift the door by hand; it should move smoothly and stay near mid-travel.
• Safety reversal test: the door must reverse when it contacts a 1-1/2 inch object (a 2x4 laid flat); test monthly.
• Force and travel limits: if you adjust one, the other may also need adjustment.

For step-by-step procedures and safety warnings, follow the 13953918D owner's manual.

Repair vs replace comparison

Factor	Repair makes sense	Replace makes sense
Issue type	Sensors, settings, remotes	Motor or repeated gear failures
Safety	Reversal tests pass consistently	Reversal cannot be made consistent
Door condition	Door is balanced and lubricated	Door binds or is unbalanced

Why it matters

A properly balanced, lubricated garage door is required for safe reversing and smooth operation. When the door binds or is out of balance, the opener can seem “worn out” and repairs will not last.

Helpful troubleshooting resources

• Use Craftsman error codes to interpret flashing lights and diagnostic patterns.

Common problems on the Craftsman 13953918D garage door opener are safety sensor faults that prevent closing (often with blinking lights), remote or wall control issues (Lock Mode or lost programming), and door or travel/force problems that cause reversals, noise, or inconsistent movement. Use the 13953918D owner's manual for the built-in troubleshooting steps and required safety tests.

Common symptoms and likely causes

• Door will not close; lights blink: safety reversing sensors blocked, misaligned, or not connected.
• Remote will not work: Lock Mode enabled, remote needs programming, or battery is weak.
• Door reverses or stops short: travel and force settings need adjustment (they interact).
• Opener runs but door is loud or struggles: door is out of balance, rollers/tracks binding, or drive components worn.
• Intermittent operation: loose wiring at sensors/wall control or electrical interference.

Quick checks we recommend first

• Clean and align both safety sensor lenses; remove anything in the beam.
• Check the motor unit diagnostic LED and match the flash pattern to the chart.
• Turn off Lock Mode on the Smart Control Panel, then test wall button and remote.
• Test the safety reversal system monthly; the door must reverse on a 1-1/2 inch object (or a 2x4 laid flat).

Troubleshooting map

What you see	Most common area	Next step
Won’t close; lights blink	Safety sensors	Align, clear obstructions, verify wiring connections
Remote won’t activate	Controls	Disable Lock Mode, reprogram remote, replace battery
Reverses unexpectedly	Travel/force	Reset travel and force together; re-test reversal
Door feels heavy/noisy	Door hardware	Inspect rollers/tracks; spring/cable work needs a door tech

Why it matters

Most “opener problems” are safety sensor alignment or door-balance issues. Fixing those first prevents nuisance reversals and reduces strain on the motor and drive system.

If your Craftsman 13953918D garage door opener will not respond to remotes or the keypad, the usual causes are Lock Mode enabled on the wall control, dead remote/keypad batteries, lost programming (needs re-learn), or a safety sensor issue that blocks remote closing.

Quick checks (fastest fixes first)

• Confirm the opener has power (opener lights turn on when activated).
• Check the wall control for Lock Mode; turn it off if enabled.
• Replace the remote and keypad batteries.
• Stand inside the garage and test again to rule out range/interference.
• If the door will open but will not close by remote, inspect the safety sensor lights and beam path.

Reprogram the remote or keypad (Learn button)

Your 13953918D uses a Learn button to add or reprogram Security+ 315 MHz remotes.

1. Press and release the Learn button on the motor unit (Learn LED stays on about 30 seconds).
2. Within 30 seconds, press and hold the remote button you want to use (or follow the keypad steps).
3. When the opener lights blink (or you hear clicks), the code is learned.

Use the exact programming steps and keypad procedure in the 13953918D owner's manual.

When safety sensors block remote operation

On this Craftsman design, if a safety reversing sensor is misaligned or obstructed, the opener may refuse to close the door from a hand-held remote. You can typically close the door using the wall control only if you keep it pressed until down travel is complete.

Symptom	Most likely cause	What to do
Door will not close by remote	Sensor beam blocked or misaligned	Clear obstruction, realign sensors
Opener lights flash after close attempt	Sensor fault detected	Check both sensor indicator lights
No response from any remote	Lock Mode or lost programming	Disable Lock Mode, reprogram

Why it matters

Remote and keypad operation is designed to shut down when the opener detects a safety risk (Lock Mode or sensor problems). Restoring normal control also helps keep the safety reversal system working correctly.
