Stinger 390LMD21V 4-Pack 1-Button 390 MHz DIP Switch Remote for LiftMaster 61LM

Stinger 390LMD21V 4-Pack 1-Button 390 MHz DIP Switch Remote for LiftMaster 61LM

The Stinger 390LMD21V is a one-button 390 MHz fixed-code DIP switch remote commonly used where the original LiftMaster 61LM remote has been discontinued or is no longer practical to source. This multipack is useful for older installations that need multiple matching remotes programmed to the same fixed-code receiver. Unlike Security+ rolling-code remotes, the 390LMD21V is set by matching physical DIP switch positions to the receiver or to a working remote.

This product is for older 390 MHz code-switch radio systems, including many LiftMaster, Chamberlain, Sears Craftsman, and Raynor units from the fixed-code era. It is often selected for garage door openers, radio receivers, and some light-duty gate operator radio controls that use 9 trinary DIP switch coding. It should not be used as a replacement for red/orange Security+ remotes, purple Security+ 315 MHz remotes, or yellow Security+ 2.0 remotes.

Technician Note

The 390LMD21V should be matched by code type, not just by frequency. A 390 MHz fixed-code DIP switch remote is different from a 390 MHz Security+ rolling-code remote. If the opener has a learn button and no DIP switches, this is usually not the correct remote family.

Before Ordering, Confirm

• The old remote or receiver uses 390 MHz fixed-code DIP switch programming
• The existing remote is a 61LM, 61RGD, or related fixed-code model
• The receiver code can be accessed and matched
• The customer does not need Security+ rolling-code operation
• The application only requires one-button operation

Professional Advisory

After setting the DIP switch code, test the remote with the door or gate in full view. Fixed-code systems are older radio platforms; if range is poor or operation is intermittent, inspect the receiver, antenna, battery, and opener wiring before assuming the remote is defective.

Questions & Answers

What does the 390LMD21V replace?

The 390LMD21V is commonly used as a replacement for LiftMaster 61LM and Raynor 61RGD style 390 MHz fixed-code DIP switch remotes.

Is this remote compatible with Security+ openers?

No. This is a 390 MHz fixed-code DIP switch remote. It is not for Security+ rolling-code openers with red/orange, purple, or yellow learn buttons.

How is the code set on this remote?

The code is set with 9-position trinary DIP switches. The switch pattern must match the compatible receiver or existing remote code.

Can this remote replace 7 or 8 switch remotes?

It may be used with some older 7- or 8-switch three-position systems when the programming instructions support the correct code conversion, but the existing receiver format should be verified.

What battery does this style of remote use?

Most 390LMD21V-style Stinger remotes use a 12V A23 battery, but the battery supplied with the actual remote should be checked before replacement.
