LiftMaster 375LMC Remote

Your LiftMaster 375LMC at a glance

Confirm the brand and the complete 375LMC label, including any additional suffix or hardware revision. A similar case or shared model number does not establish an interchangeable remote.

375LMC battery & holder

One 3 V CR2032.

Programming your 375LMC

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

Supported Learn/DIP systems only; residential use limited to post-1993 openers with photoelectric safety sensors.

Other brand/generation press counts must be matched to exact receiver; current replacement not verified.

Checks for 375LMC

• Two-position DIP failures may require the manual-specified ON/OFF reversal.

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.

375LMC 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.
