Repair Service Chamberlain 41AC050-1M and 50 similar items

?1. Remote Control Failure (Most Common) ?This is the single most frequent indicator that the logic board is failing while the motor itself is fine. Total Radio Silence: None of your remotes work, even with fresh batteries. Refusal to Program: The unit will not enter "Learn" mode. When you press the purple button, the LED either doesn't light up at all or never blinks to confirm it has accepted a new code. Drastically Reduced Range: The remotes only work when you are standing inside the garage, practically touching the antenna wire. "Ghost" Openings: The door opens or closes on its own without anyone pressing a button (often caused by shorts in the receiver circuit). ?2. Strange Motor Behavior The "Click" of Death: When you press the wall button, you hear a distinct click from the motor unit (the relay engaging), but the motor does not turn. Note: This can also be caused by a bad start capacitor. See the troubleshooting section below. Stops or Reverses Randomly: The door starts to move but stops or reverses for no apparent reason, even though the tracks are clear and the force settings are correct. One-Way Operation: The door will open but refuses to close (often accompanied by the main light flashing), even though the safety sensors are aligned and glowing steady. ?3. Power Lighting Anomalies Dead Wall Control: The LED on your wall-mounted push button goes dark or flickers, and the button ceases to function. Main Light Malfunction: The light bulb on the opener stays on permanently and won't turn off, or it never turns on at all. Intermittent Power: The unit acts completely dead (no lights, no sound) but then randomly starts working again later. This is often due to a hairline crack in the solder joints on the back of the board that expands and contracts with temperature changes.
