Questions and answers
On my elite miracle one unit, the Power and Charge lites are lit and the motors are not engaging. I hear a clicking sound when remote is pressed, however, the gats do not open.
The motors on a Chamberlain Miracle-One unit may not engage despite the Power and Charge lights being lit and a clicking sound being heard due to the following possible causes:
1. Incorrect Installation – The gate operator or gate may not be installed correctly.
2. Gate Hinges Issues – Hinges may be too tight or broken, preventing movement.
3. Obstruction – The gate may be hitting the driveway, curb, or another object, causing it to get stuck.
4. Overload or Fault Condition – The alarm LED may indicate that the gate is too heavy or there is a mechanical issue.
5. Electrical Malfunction – A stuck relay or a wiring issue could cause the clicking sound without actual motor engagement.
Checking for these issues and ensuring proper installation and gate movement should help diagnose and resolve the problem.
