The 139.53985DM is a Craftsman 315 MHz Security+ opener. Its owner’s manual documents LEARN-button remote and keypad programming plus erase-all-codes behavior; confirm the installed LEARN-button color before choosing a current replacement accessory.
Confirm this is the opener you have
Use several source-backed clues together. The motor-unit label remains the strongest identity clue.
Use the full motor-unit label for model identity; do not identify from opener case shape alone.
Use the active receiver or Learn-button generation before ordering a remote.
Model specifications that matter for troubleshooting
Remote / accessory evidence tied to this model
These rows come from the verified compatibility dataset. An added external receiver can still change the active radio path.
Verify purple/brown LEARN-button generation, then use the current Craftsman compatibility row
Keep exact model/board identity separate from remote generation. Current universal options may span generations, legacy remotes may not.
Remote and keypad memory share the same learned-device system
The owner’s manual documents remote programming and keyless-entry PIN programming through the opener’s LEARN state. Erasing the opener memory therefore affects learned access devices and should be treated as a deliberate reset, not a casual troubleshooting step.
Before erasing memory, inventory the remotes and keypad that need to be restored.
Model suffix matters for parts even when the radio generation matches another Craftsman
Several Craftsman openers share 315 MHz Security+ behavior, but that does not make their logic boards, rails, wall controls or mechanical parts interchangeable.
Use the exact 139.53985DM label for parts and the LEARN-button generation for remote/keypad compatibility.
The Premium Control Console gives a second programming path, not a second memory bank
This model family can be programmed from the motor-unit LEARN control or through the Premium Control Console sequence documented for the opener. Those are two ways to enter the same learned-device system; they do not create separate sets of remote memory.
That distinction is useful when troubleshooting. If a compatible remote can be enrolled from one control point but the other programming path will not respond, investigate the wall-control path, low-voltage wiring or console behavior before blaming the radio receiver. If neither path accepts a verified-compatible device, then receiver-side diagnosis becomes more relevant.
Common troubleshooting paths for this model
Route from the observed symptom or code. Do not use model identity by itself as proof of the failed part.
Remote/keypad programming
Use the current compatible accessory first, then follow the learned-device procedure for the installed opener.

A clean handoff preserves the evidence that separates opener identity, receiver compatibility and the actual failure symptom.
Motor-unit label
Photograph the full label showing 139.53985DM. Use that label for manuals and model-specific parts.
Active receiver / Learn control
Record the Learn-button color or external receiver model separately. A replaced receiver can change remote compatibility without changing the opener model.
Exact symptom or signal
Write down the code, blink count, sensor LED pair, direction of travel and where the door stops or reverses before changing settings.
Door-system boundary
If the door is crooked, off-track, unusually heavy, or has damaged spring/cable hardware, stop opener troubleshooting and hand off the mechanical door problem.
Model-specific guardrails
- Do not erase opener memory unless you are prepared to reprogram all desired access devices.
- Part compatibility follows the exact model/board number, not radio frequency alone.
- Use Sears model diagrams for hardware identification and Chamberlain Group’s live compatibility table for current remotes/keypads.
Never use opener force or a safety-system bypass to compensate for a heavy, damaged, off-track or unbalanced garage door.
Craftsman 139.53985DM common questions
Is the 139.53985DM a 315 MHz opener?
Yes. The model’s owner documentation identifies the opener as a 315 MHz Security+ unit.
Does erasing codes only remove one remote?
No. The manual’s erase procedure clears stored remote/keyless-entry codes, after which desired devices must be programmed again.
Verified model sources used
These manufacturer, manual and official parts/support sources are the factual baseline for the model identification and specifications above. Current manufacturer documentation supersedes older copies found elsewhere.
