Hello I have a craftsman 1/2 HP garage door opener. It was manufactured in 1998. It no longer is opening or closing. It's stuck open right now. When you try to close it there is just a short click or hum type sound from the unit but nothing else. There is an LED flashing on the circuit board next to an orange button. If I push the orange button the light stops flashing and stays on steadily. I try again and the opener fails to work and the light starts flashing again. It seems to flash 5 times then pause and flash 5 times again.
1. Is this light a troubleshooting aid? If so what does the 5 flashes indicate?
2. Can anyone tell me why there are 3 wires going into the motor? I wanted to just jump power to the motor to see if the motor was the issue.
3. Which wires would I have to apply power to test just the motor?
Thanks for any help in advance.
