If your LiftMaster garage door won't open even when using wall switch, which directly controls opener bypassing remote issues, problem is likely with opener power, safety sensors, travel limits, or mechanical binding rather than remote. First, check if opener has power, as lights on opener unit and wall console should be on, and ensure outlet is working and opener is plugged in, as tripped GFCI or breaker can cut power. Check if door is locked manually, as some garage doors have manual slide lock on track that prevents opening and must be disengaged. Inspect safety sensors near floor, as even though sensors primarily prevent closing, misaligned or dirty sensors can cause opener to not respond to open command in some models, so clean lenses and ensure both LEDs are solid. Check travel limits, as if open limit is set incorrectly or logic board failed, opener may hum but not move door, requiring limit adjustment via screws on opener. Listen for motor humming, as if motor hums but door doesn't move, trolley may be disconnected or drive gear stripped, or door is binding due to broken spring or off-track rollers that prevent manual opening, so try opening door manually by pulling emergency release cord and lifting door, and if door is very heavy or won't lift, spring may be broken costing 200 to 400 dollars to replace professionally. Also check for lock mode engaged on wall console that disables opening. If opener is old, logic board may have failed and needs replacement.
