Craftsman model hubs
139.53970SRT
The 139.53970SRT belongs to Craftsman’s early post-UL-325 opener era. Before buying an accessory, verify the motor-unit LEARN button and full label; this family is commonly documented in the green-button / 390 MHz Billion Code generation rather than the later red/orange, purple or yellow systems.
Open model hub →Craftsman model139.53975SRT1
The 139.53975SRT1 is a 1/2-HP Craftsman opener documented with Security+ remotes, a Premium Control Console and safety reversing sensors. Legacy compatibility references place this family in the red/orange 390 MHz Security+ generation; verify the actual LEARN button before buying a replacement remote.
Open model hub →Craftsman model139.53918D
Craftsman 139.53918D is documented as a 315 MHz Security+ opener with a purple LEARN button. Sears PartsDirect also hosts an exact REV F owner manual whose Learn-button diagnostic chart uses 1–5 flashes; its fifth flash is a model-specific 'motor RPM is not recognized' branch rather than the generic Craftsman 1–6 table.
Open model hub →Craftsman model139.53985DM
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.
Open model hub →Craftsman model139.3043
The 139.3043 is a later Craftsman opener with programmable travel, a 41B822 battery-backup system and AssureLink-era smart-control features. Sears parts data lists the 45DCT receiver/logic-board family; replacement-accessory decisions should be checked against the installed yellow-button Security+ 2.0 receiver and the current Craftsman chart.
Open model hub →Craftsman model139.53914D
The Craftsman 139.53914D owner manual identifies a 1/2 HP, 315 MHz opener and its assembly procedure uses a belt. Treat the exact motor-unit label as the model identity, then verify the installed Learn-button/receiver before choosing a current remote or keypad.
Open model hub →Craftsman model139.53920D
The 139.53920D manual identifies a 1/2 HP, 315 MHz Craftsman opener and documents a chain/cable drive layout. Use the model label for parts and diagnostics; use the installed receiver/Learn button for current remote compatibility.
Open model hub →Craftsman model139.53930DM
The Craftsman 139.53930DM owner manual identifies a 1/2 HP, 315 MHz opener with a chain/cable drive. Its manual also includes a self-diagnostic Learn-button LED chart, making exact flash evidence more useful than a generic Craftsman reset.
Open model hub →Craftsman model139.53985D
The 139.53985D manual identifies a 1/2 HP, 315 MHz Craftsman opener. Preserve the D suffix: Sears also indexed 139.53985 and 139.53985DM variants, and matching the radio generation does not make their parts diagrams interchangeable.
Open model hub →Craftsman model139.53990D
The 139.53990D owner manual identifies a 3/4 HP, 315 MHz Craftsman chain-drive opener. Sears still indexes the exact model with manuals and parts diagrams, but many original parts are discontinued; identify the active receiver before buying a current remote.
Open model hub →Craftsman model139.53992D
The 139.53992D manual identifies a 1/2 HP, 315 MHz Craftsman opener and its parts list explicitly includes a screw-drive rail assembly and screw-drive RPM kit. Do not import chain-drive troubleshooting just because nearby 139.x model numbers look similar.
Open model hub →Craftsman model139.53993D
The 139.53993D owner manual identifies a 1/2 HP, 315 MHz Craftsman opener and its own assembly/parts pages document a drive screw and screw-drive RPM kit. Preserve the exact model before applying mechanical advice from a chain-drive 139.x opener.
Open model hub →Craftsman model139.53997D
The 139.53997D owner manual identifies a 3/4 HP, 315 MHz Craftsman opener and documents a chain/cable rail system, diagnostic chart and Motion Detecting Control Console. Use those exact-model facts for diagnosis while verifying the active receiver for current remote compatibility.
