Craftsman 13953985 garage door opener Parts

For a 20-year-old garage door opener, replacement is usually the better long-term choice because most openers are designed to last about 10 to 15 years, and newer units typically add meaningful safety and security improvements. If your Craftsman 13953985 only needs a small fix or adjustment, a repair can make sense short-term.

When repair makes sense

A repair is worth doing when the problem is limited to setup, wiring, or adjustments you can verify quickly.

• The opener has power issues you can trace to an outlet, breaker, or wall switch
• The wall control works but the remote does not (or vice versa)
• The door is binding due to ice, snow, or a door lock still engaged
• The motor overload protector tripped after repeated cycles (waiting about 15 minutes restores operation)
• The issue is travel limits or force settings that need a careful reset and retest

For model-specific adjustment and troubleshooting steps, use the owner's manual.

When replacement is the smarter move

Replacement is the better investment when the opener has major mechanical or safety-related concerns.

• The garage door is not properly balanced (it can fail to reverse when required)
• The opener will not consistently pass the monthly safety reversal test
• You suspect a broken spring or door hardware problem (these repairs require a trained door systems technician)
• You have repeated failures that point to motor, logic board, or drive system wear
• You want modern features such as quieter operation, better security, or smart control

Safety checks you should do before deciding

The Craftsman 13953985 manual calls out a monthly safety reversal test using a 1-inch object (or a 2x4 laid flat). If the opener cannot be adjusted to reverse reliably, replacement is the practical path.

Check	What you do	What “pass” looks like
Safety reversal test	Close the door onto a 1-inch object	Door reverses on contact
Door balance	Disconnect opener and lift door by hand	Door stays near mid-travel without drifting
After adjustments	Run 3 to 4 full cycles	Smooth travel, consistent reversing

Why it matters

An opener that does not reverse correctly can create a serious closing hazard. Deciding based on safety reversal performance and door balance keeps the door system safe and prevents repeated breakdowns.

Yes. For a Craftsman garage door opener model 13953985, you can typically use a compatible “universal” remote as long as it supports the opener’s radio system (many units of this era use Security+ rolling-code). You can also add an external receiver kit if you want broader remote compatibility.

How to confirm compatibility (what to check)

• Look for a LEARN button on the motor unit; this is used to program remotes.
• Identify the opener’s remote technology (often Security+ on older Craftsman units).
• Check whether you need a single-button remote or a 3-function remote.
• Confirm how many devices you plan to use; this opener can typically store multiple remotes.
• If the opener is very old or uses an uncommon frequency, plan on adding an external receiver.

How to program a new remote (typical steps)

We follow the same basic process described in the 13953985 owner's manual:

1. Press and release the LEARN button on the motor unit (the indicator light stays on briefly).
2. Within about 30 seconds, press and hold the button on the remote you want to use.
3. Release when the opener lights blink or you hear clicks; the remote is learned.

If you need to remove old remotes first

If you are replacing lost remotes, erase the opener’s memory and then reprogram only the remotes you still have (the manual describes holding the LEARN button until the indicator light goes out).

Universal remote vs external receiver: which is better?

Option	Best when	What you gain	Tradeoff
Universal remote	Your opener uses a common system like Security+	Simple, low-effort setup	Must match the opener’s supported tech
External receiver + remote	Your opener is too old or not compatible	Works with more remote types	Extra wiring and mounting

Why it matters

A remote that does not match the opener’s programming system will not learn to the motor unit, even if it “looks right.” Using the LEARN-button method ensures the remote is actually paired to your Craftsman 13953985 opener.

To find your garage door opener type for Craftsman model 13953985, first identify your door style (sectional or one-piece) and then confirm the opener’s drive system (chain, belt, or screw) by looking at the rail and trolley assembly. Use the owner's manual to match what you see to the diagrams.

Step 1: Identify your garage door type (most important)

Your opener setup and adjustment steps depend on the door style.

• Sectional door: multiple horizontal panels that roll up on tracks
• One-piece door with track: a single solid door that still uses a track system
• One-piece door without track: a single solid door that swings up without a standard track

Quick visual check

What you see	Door type	Why it matters
Hinges between panels	Sectional	Uses standard opener arm and bracket positioning
One solid panel plus track hardware	One-piece with track	Rail clearance and arm setup differ
One solid panel, no typical track	One-piece without track	Opener positioning and arm geometry differ

Step 2: Confirm the opener drive type

Look at the rail above the door and the moving trolley.

• Chain drive: a metal chain runs along the rail (often the easiest to spot)
• Belt drive: a rubber-like belt runs along the rail (quieter than chain)
• Screw drive: a threaded steel rod runs down the rail (less common on newer units)

Step 3: Use built-in identifiers on the opener

These checks help you confirm you are looking at the right system.

• Check the motor unit label for the model number 13953985
• Note whether you have Safety Reversing Sensors at the bottom of the door opening
• Identify your control style (wall control, remote, keyless entry) and use programming steps in the manual

Why it matters

Door type and drive type affect installation clearances, force and travel adjustments, and troubleshooting. For example, misaligned safety sensors can prevent the door from closing properly and may cause the opener lights to blink.

Your Craftsman garage door opener’s model number is printed on the product label on the motor unit (the ceiling-mounted head). For model family 139.53985, the label is commonly behind a light lens; it may include a letter suffix after the numbers.

Where to find the model label

Check the motor unit housing in these common spots:

• Under the front light lens cover
• Under the left light lens cover (when you are facing the garage door)
• On the side or back panel near where the antenna wire exits
• Near the “learn” button area on the motor unit panel

How to read the number you find

Craftsman openers often show the model in a dotted format and may add letters.

• You may see 139.53985 plus a suffix such as 139.53985D or 139.53985DM
• The full label text (including any letters) is what you should use when matching parts, remotes, and programming steps

What you see on the label	What to do with it
139.53985 (with or without letters)	Use the full printed model to match documentation and parts
Serial number	Keep it for records; it is not used to pick most replacement parts
Motor rating (example: 1/2 HP)	Helps confirm you are looking at the correct label

Quick checklist to locate it safely

• Unplug the opener or switch off the breaker before opening a lens cover
• Open one light lens and look for a printed sticker on the housing
• If it is not there, check the other lens and then the side/back near the antenna
• Once found, compare it to the model shown in the 13953985 owner's manual

Why it matters

Using the exact model number (including any letter suffix) prevents mismatched remote programming, incorrect safety sensor troubleshooting, and ordering the wrong Craftsman garage door opener parts.
