Transmitter Solutions 390LMD21V 390 MHz DIP Remote for 139.53651

Transmitter Solutions 390LMD21V 390 MHz DIP Remote for 139.53651

The Transmitter Solutions 390LMD21V is a replacement-style remote control for older 390 MHz DIP switch garage door opener radio systems. This product is commonly used when replacing discontinued Sears Craftsman and LiftMaster 61LM-style remotes on fixed-code systems where the remote code is set by physical DIP switch positions rather than a modern learn-button rolling code. For this listing, the main application is 139.53651, along with related Sears Craftsman, Chamberlain, LiftMaster, and Raynor systems that use the same 390 MHz DIP switch format.

This remote is a good choice when the original transmitter is cracked, missing, has weak range, or no longer sends a reliable signal. The important detail is the radio technology. Older 390 MHz DIP switch systems are different from Security+ rolling-code remotes, even when the openers look similar or were sold under the same Craftsman or LiftMaster brand family. The installer or customer should match the DIP switch pattern from the old remote or receiver and confirm that the opener is not a red/orange, purple, or yellow learn button Security+ system.

Compatible With

The 390LMD21V is commonly associated with older 390 MHz fixed-code DIP switch systems and 61LM-compatible replacement applications. Compatibility depends on the receiver technology and DIP switch format, not just the opener brand name.

Common Compatible Products and Systems

• Sears Craftsman 139.53632SR
• Sears Craftsman 139.53639
• Sears Craftsman 139.53639SR
• Sears Craftsman 139.53651
• LiftMaster 61LM
• LiftMaster 62LM 2-button family, when matched to a compatible 390 MHz DIP receiver
• Select Chamberlain, LiftMaster, Sears Craftsman, and Raynor fixed-code 390 MHz 8 or 9 DIP switch systems
• Older 7-position or 8-position three-position switch systems when the replacement remote can be set to the matching code pattern

Important Compatibility Notes

• For older fixed-code 390 MHz DIP switch systems only.
• Not for Security+ 390 MHz red/orange learn button systems unless a compatible DIP receiver is being used.
• Not for Security+ 315 MHz purple learn button or Security+ 2.0 yellow learn button openers.
• Model numbers on old remotes can overlap across Sears, Craftsman, Chamberlain, Raynor, and LiftMaster labeling, so match the receiver code type and DIP pattern.

Technician Note

Do not confuse 390 MHz DIP switch remotes with 390 MHz Security+ remotes. A fixed-code 61LM-style transmitter is programmed by matching DIP switch positions, while a Security+ transmitter learns to a red/orange learn button receiver. If the customer has a learn button opener, check the learn button color before choosing this remote.

Before Ordering, Confirm

• The original remote or receiver uses 390 MHz fixed-code DIP switch technology.
• The receiver has 8 or 9 DIP switch coding or a compatible trinary switch pattern.
• The opener is not a Security+ rolling-code or Security+ 2.0 yellow learn button opener.
• The replacement remote is being used for one compatible receiver code.
• The old remote model, receiver model, or opener documentation references 61LM-style fixed-code operation.

Professional Advisory

Program and test the remote only while the garage door is in clear view. Do not use a remote control to operate a door with broken springs, damaged hardware, failed safety sensors, or unsafe movement. If the door does not operate smoothly by hand, correct the door problem before relying on the opener or remote control system.

Important Ordering Warnings

• Not a Security+ rolling-code remote.
• Not for purple learn button 315 MHz systems.
• Not for yellow learn button Security+ 2.0 systems.
• Old Sears and Craftsman remote model numbers can be confusing; match frequency and DIP switch coding before ordering.

Questions & Answers

Is the 390LMD21V used for 139.53651?

Yes, the 390LMD21V is commonly used as a replacement-style remote for 139.53651 and related older Sears Craftsman 390 MHz DIP switch opener systems when the receiver uses compatible fixed-code programming.

Is this the same type of remote as a 61LM?

It is commonly sold as a 61LM-compatible replacement-style remote for older 390 MHz DIP switch systems. The code pattern must be set to match the existing receiver or original transmitter.

Will this work with Security+ rolling-code openers?

No. This remote is for older fixed-code DIP switch systems. It is not a Security+ rolling-code remote for red/orange, purple, or yellow learn button openers.

What should I check before programming this remote?

Check the receiver frequency, DIP switch count, switch position pattern, and whether the system uses fixed-code 390 MHz technology instead of Security+ rolling-code technology.

Can one remote operate more than one opener?

This is a single-button style remote for one compatible receiver code. Multiple doors usually require matching the same code or using separate compatible transmitters, depending on the receiver setup.
