QUESTION: There is no power going to the door sensors and there is no power going to the garage wall button to open the garage door. I would like to know if this is an indication that I need to replace the logic board. there is power going to the motor. What do I need to replace to get it working? by None N 6/22/2015
ANSWER: Also, if you can use a soldering iron, you will find that you possibly have a cold solder joint on the main relay on the circuit board. Very common issue, especially in hot garages. A soldering iron and a touch of solder will correct this issue. To confirm this, with power applied, and with no light on the sensors and the wall control, just press on the back of the circuit board on the left side , and see if you hear a click and the lights now come on. If you get this indication , the the above will correct the issue. by Steve D a

QUESTION: There is no power going to the garage door sensors and there is no power going to the garage wall button. There is power going to the motor and the light on the opener. Is this a symptom for the logic board to be replaced? by None N 6/21/2015
ANSWER: It's usually the logic board when you have those symptoms. My opener was doing the same thing. The motor would hum for a few seconds then nothing. Replacing the logic board fixed it but other things can cause the same symptoms. Make sure the chain hasn't jammed against the stop bolt before you start replacing things. That's simply fixed by loosening the chain. A bad capacitor can also cause the motor to just hum. Hope that helps. by Janet B a
