LiftMaster 372LM Remote

Your LiftMaster 372LM at a glance

Confirm the brand and the complete 372LM label, including any additional suffix or hardware revision. A similar case or shared model number does not establish an interchangeable remote.

372LM battery & holder

Two 3 V CR2032 cells, positive faces up.

Programming your 372LM

Setup depends on the exact receiver and hardware revision. These model notes do not establish a complete pairing sequence for your equipment.

Match both the remote and opener or external receiver. Keep the door or gate in sight and clear of people. Do not hold a LEARN button or erase memory unless the instructions for that exact equipment require it.

Compatibility & exclusions

315 MHz Security+ purple-Learn receiver; right button also learns eligible CGI 315 MHz fixed/billion-code remotes.

Replacement equivalence and receiver-specific commercial/gate enrollment remain unverified unless separately documented.

If your 372LM is not working

Checks for 372LM

• Only right button is trainable; left remains Security+. Both buttons held about ten seconds restore right button to Security+; this is not receiver-memory erasure.

General troubleshooting checks.

• No response: check the marked battery type and polarity; note whether another authorized control works.
• Short range: note when the problem began and whether it changes by location. Do not alter receiver wiring.
• Damaged case or buttons: keep the model label; stop using exposed, wet or damaged electronics.

372LM repair, parts & replacement

No exact replacement or part mapping has been confirmed for this page. A similar-looking remote, matching frequency or familiar model family is not sufficient evidence of interchangeability.

Model guides

Use the model-specific notes on this page with the instructions for your opener or receiver. A documented receiver match does not establish compatibility with every opener.
