### 1. **Check Power Supply**

– Check for a tripped circuit breaker or blown fuse. Reset the breaker or replace the fuse if needed.

### 2. **Inspect Remote and Wall Switch**
– Replace the batteries in the remote control.
– Check the functionality of the wall switch. If it’s unresponsive, it may need to be replaced.

### 3. **Examine Safety Sensors**
– Look for any obstructions in the path of the safety sensors located near the floor on either side of the door.
– Make sure the sensors are aligned properly; the indicator lights should be lit without blinking.
– Clean the lenses of the sensors with a soft cloth to remove dust or debris.

### 4. **Check Door Tracks and Rollers**
– Inspect the tracks for any bends or obstructions that could prevent the door from moving smoothly.
– Lubricate the rollers and tracks using a silicone-based lubricant to reduce friction.

### 5. **Inspect the Garage Door**
– Ensure the door is not off its hinges or misaligned.
– Test the door manually by disconnecting it from the opener (using the emergency release cord). If it doesn’t move smoothly, look for issues with the door itself.

– Adjust the force and travel limits settings as needed. This can usually be done with knobs or buttons on the motor unit.

### 8. **Inspect the Drive Mechanism**
– Check whether the chain or belt (depending on your model) is properly tensioned and lubricated.
– Look for any fraying or wear in the belt or chain.

### 9. **Test for Obstructions**
– Make sure there are no objects blocking the door’s path, as this could cause the door to reverse unexpectedly.

### 10. **Reset the Opener**
– If all else fails, consider resetting the opener by unplugging it for a few minutes and then plugging it back in.

### 11. **Consult the Manual**
– If you’re still experiencing issues, refer to your user manual for specific troubleshooting tips related to your model.
