Craftsman 13955918 garage door opener Parts

Your Craftsman garage door opener model number is printed on a label on the powerhead (the motor unit mounted to the ceiling). On many Craftsman openers, you can find it under a light lens cover, often on the side opposite the antenna. For model-specific label locations, use the 13955918 owner's manual.

Where to look on the opener (most common spots)

Check the powerhead housing for a white or silver label. Look in these places:

• Under the front light lens cover
• Under the left light lens cover (when you are facing the opener from inside the garage)
• On the side panel opposite the antenna wire
• Near the learn button area (behind a light cover on many units)
• On the back or underside of the motor unit near the hanging bracket

What to write down (so you get the right parts)

When you find the label, record these items exactly as shown:

• Model number (example for this page: 13955918)
• Manufacturing date or date code (if listed)
• Motor unit logic board number (if listed)
• Remote/keypad “learn” color (if shown; helps match remotes)

Label item	Why it matters	Example format
Model number	Matches the correct parts list and diagrams	13955918
Date code	Helps confirm compatible revisions	2020-05 or similar
Learn color	Helps identify remote compatibility	Yellow/Purple/Red/Green

If the label is missing or unreadable

Use these quick checks to narrow it down:

• Look for a model label on the opener’s end panel or under a light cover
• Check the wall control and remote for a part/model label
• Note whether it is chain drive or belt drive (helps match common parts)
• Watch the opener lights for blink patterns and compare them to Craftsman error codes

Why it matters

Garage door opener parts (logic boards, wall controls, safety sensors, remotes, and drive gears) are model-specific. Using the exact model number prevents ordering the wrong Craftsman replacement part and speeds up troubleshooting.

For a 20-year-old garage door opener, replacement is usually the better long-term choice because most openers are built to last about 10 to 15 years. For a Craftsman model 13955918, a small repair can make sense if it is inexpensive and the door is otherwise running smoothly, but major failures typically justify upgrading.

Quick decision guide

• Repair if the problem is minor (remote battery, sensor alignment, loose wiring at the wall control).
• Replace if the opener struggles to lift the door, reverses randomly, or needs repeated force/travel adjustments.
• Replace if you want modern features (quieter operation, better security, smart controls).
• Repair if the door itself is the real issue (binding rollers, dry hinges, tight springs) and the opener is fine.
• Replace if parts and troubleshooting time are adding up.

What to check first (before spending money)

Use the steps and adjustment procedures in the owner's manual. Then verify these common items:

• Safety sensors: both LEDs steady, lenses clean, brackets not bent
• Door balance: door should stay about halfway open when released (a heavy door overloads the opener)
• Force and travel settings: set only as needed; too much force is a safety risk
• Drive system: chain/belt tension and obvious wear
• Wall control and wiring: intermittent shorts can mimic a failing logic board

Repair vs. replace comparison

Situation	Usually best choice	Why
Remote or keypad issues	Repair	Low cost, quick fix
Door will not close and lights blink	Repair (often sensors)	Alignment/obstruction is common
Motor runs but door barely moves	Replace (or major repair)	Worn gears/motor, high labor
Frequent reversals or inconsistent travel	Replace	Aging components, reliability issues

Why it matters

An older opener that is out of adjustment or fighting a heavy, unbalanced door can become unreliable and can reduce safety. A newer opener also typically improves security and day-to-day convenience.

If your Craftsman garage door opener model 13955918 won’t respond to remotes and/or the keypad, start by testing the wall control. If the wall button works, the issue is usually power to the remote/keypad, programming, interference, or the opener’s receiver. Use the 13955918 owner's manual for the exact learn/program steps.

Quick checks (fastest fixes first)

• Make sure the opener has power (opener lights on, or wall control has indicators).
• Replace the batteries in every remote and the keypad.
• Confirm the wall control is not in Lock/Vacation mode (this disables remotes/keypad).
• Check that the opener’s hanging antenna wire is intact and pointing down.
• Remove common interference sources near the opener (some LED bulbs, chargers, Wi-Fi devices).
• Power-cycle the opener: unplug for 30 to 60 seconds, then plug back in.

What the wall button test tells you

What works?	Most likely cause	What to do next
Wall button works; remotes/keypad do not	Wireless issue (battery, lock mode, programming, interference, receiver)	Reprogram and reduce interference
Wall button and remotes/keypad all fail	Power, wall control wiring, logic board, or a safety condition	Check power, sensors, and wiring
One remote fails; others work	That remote is bad or unprogrammed	Replace battery; reprogram that remote

Reprogram and reset (common for sudden “all remotes stopped”)

1. Reprogram each remote and the keypad using the learn procedure in the 13955918 owner's manual.
2. If programming won’t “take,” erase all devices from memory, then re-add them.
3. If range is very short, swap any LED bulbs in the opener light sockets for garage-door-opener-compatible bulbs.

If the door won’t close (even though it opens)

Safety sensors can block closing and make it seem like the keypad/remote is ignored.

• Confirm both sensor LEDs are on and steady.
• Clean the sensor lenses and realign them.
• Check for staple or pinch damage on the sensor wires.

Why it matters

Remote/keypad failures are often simple (battery, lock mode, interference), but a no-response condition can also point to a receiver/logic issue. Testing the wall control first prevents unnecessary parts swapping.

Common problems on a Craftsman garage door opener like model 13955918 usually fall into three buckets: safety sensor issues (door will not close), drive or door hardware problems (grinding, slipping, partial travel), and control/electrical problems (remote or wall button not responding). The fastest path is to match symptoms to the checks in the 13955918 owner's manual.

Most common symptoms and what they usually mean

• Door will not close and opener lights blink: safety sensors are blocked, misaligned, or have wiring damage.
• Door reverses when closing or stops mid-travel: travel limits or force settings need adjustment; door may be binding.
• Grinding noise or motor runs but door barely moves: worn drive gear/worm gear, loose chain/belt, or trolley issue.
• Remote/keypad works sometimes or not at all: dead battery, lost programming, RF interference, or receiver/logic board issue.
• Wall control is dead: loose wiring at the wall control terminals, bad wall control, or logic board problem.
• Door is heavy or jerky by hand: door springs/rollers/hinges need service; the opener is reacting to excess resistance.

Quick checks we recommend before replacing parts

1. Test the door balance: pull the emergency release and lift the door by hand. It should move smoothly and stay near mid-height.
2. Inspect and align safety sensors: clean the lenses, confirm both LEDs are steady, and verify the brackets are not bent.
3. Check the rail and drive: look for slack chain/belt, a cracked gear housing, or a trolley that is not engaging.
4. Reprogram controls: re-learn the remote/keypad to the opener (steps vary by logic board).
5. Confirm settings: adjust travel/force only in small increments; then retest the safety reversal.

Symptom-to-fix guide (at a glance)

What you notice	Most likely cause	Best first action
Won’t close; lights blink	Safety sensor alignment/obstruction	Clean, align, check wiring
Reverses on close	Force/travel set too sensitive or door binds	Inspect door movement; adjust force/travel
Motor hums; door doesn’t move	Stripped gear or drive issue	Inspect gear area; check chain/belt tension
Remote won’t work	Battery/programming/interference	Replace battery; reprogram; reduce interference

Why it matters

Most “opener problems” are actually safety sensor alignment or door resistance issues. Fixing those first prevents repeat failures, protects the logic board and drive gears, and keeps the safety reversal system working correctly.

For blink patterns and diagnostic flashes, use our Craftsman error codes reference to narrow the cause quickly.
