Liftmaster 41C494-1, 41A5273-8 Wall Control Panel Chamberlain 041C0494-1 Garage
The 41C0494-1 wall control panel is a low-voltage interior wall station used to operate select Chamberlain, LiftMaster, and related Craftsman residential garage door openers from the older Security+ generation. Depending on the exact version, this control family may include a main door-control button and related light or lock functions that communicate with the opener through the wall control wiring. It is commonly replaced when the button is physically worn, the plastic housing is damaged, the opener only responds intermittently from the wall, or light/lock features stop working. Correct compatibility matters because newer Security+ 2.0 openers, many smart wall controls, and some basic push-button circuits use different control logic. Similar-looking wall controls may connect to the same two low-voltage wires but still not communicate properly with the opener.

Technician Note
When troubleshooting a wall station, separate the wall control from the wall-control wiring. A shorted wire, loose terminal, or damaged opener logic board can mimic a bad button. If a new wall control does not correct the symptom, inspect the wiring run and opener terminals before replacing more parts.
Before Ordering Checklist
- Match the original wall control number or the opener parts diagram.
- Confirm the opener is an older compatible Security+ style unit, not a newer Security+ 2.0 yellow learn button opener.
- Inspect low-voltage wall control wiring for staples, shorts, corrosion, or loose terminal screws.
- Confirm the opener operates normally from a compatible remote before assuming the wall control is the only issue.
- Compare the button style and functions needed, such as door control, light control, or lock function.
Professional Advisory
Wall controls use low-voltage wiring, but the garage door opener is still a powered moving machine. Disconnect power before servicing, and have a technician inspect the system if the door reverses incorrectly, moves unexpectedly, or has damaged safety sensors.
Important Ordering Warnings
- Not compatible with most newer Security+ 2.0 yellow learn button openers.
- Do not assume all two-wire wall controls are interchangeable.
- If the opener moves by itself or ignores safety reversal, stop using the operator and have it inspected.
Product Questions and Answers
Will this wall control work with Security+ 2.0 openers?
No. This style wall control is for select older Chamberlain, LiftMaster, and Craftsman Security+ residential garage door openers and is not for newer Security+ 2.0 units that use yellow learn button technology.
Why are there several numbers listed for this wall button?
Chamberlain and LiftMaster service parts often appear under service kit, board, and stamped housing numbers. Commonly searched numbers for this wall control family include 41C494-1, 041C0494-1, 41A5273-8, and related 2C494 references depending on the version.
Can I replace a plain push button with this control?
Only if the opener supports this Security+ door control style. Older basic two-wire push buttons and newer digital wall controls may not use the same functions, so the opener manual or parts diagram should be checked.
What symptoms can point to a bad wall control?
Common symptoms include no response from the wall station, intermittent light or lock functions, damaged button contacts, cracked housing, or a wall station that works only when the wiring is moved. Wiring and opener board issues should be ruled out before replacing parts.
Does this wall control include opener remotes or safety sensors?
No. This listing is for the replacement wall control panel only unless the product packaging states otherwise. Remote controls, safety sensors, and other accessories are separate parts.
