Battery Troubles
If you notice your Mighty Mule status light blinking, it often indicates battery issues. These issues could stem from various factors. Addressing these problems can restore your gate opener’s optimal function.
Low Battery
A low battery is a common cause of a blinking status light. The battery may not be holding a charge. Check the voltage using a multimeter. A fully charged battery should read around 12.5 volts or higher. If the reading is below this, your battery needs recharging.
Battery Age
The age of your battery can affect its performance. Most gate opener batteries last between 3 to 5 years. If your battery is older, it might be losing its ability to hold a charge. Replacing an old battery can resolve the blinking status light issue.
Corrosion

Sensor Issues
The Mighty Mule status light blinking can indicate sensor issues. Sensors are crucial for gate operation. They detect obstacles and ensure smooth functioning. Problems with sensors can cause the status light to blink.
Obstructions
Obstructions can block the sensor’s line of sight. This makes the status light blink. Check for any objects in front of the sensors. Remove any obstacles to restore normal operation.
Alignment Problems
Sensors need proper alignment to work correctly. Misaligned sensors can cause the status light to blink. Ensure both sensors face each other. Adjust their positions if necessary.
Dirt And Debris
Dirt and debris can cover the sensor lenses. This may cause the status light to blink. Clean the sensors regularly. Use a soft cloth to wipe the lenses. Keep the sensors free from dirt.
