I replaced the battery within my ATA garage door opener and the door won't start on. When I press the button on the handset the red frothy stays on continously. I have tried to re-code the headset but it won't let me - the red insubstantial just stays on. I enjoy looked up on the internet as well as surrounded by the instruction book and it says nil about the red pallid staying on. The remote is about 6 months prehistoric.
Electricity problems?
Answers:    is there a screw holding the freestyle cover on? it may be overtightened. be sure battery is surrounded by correctly. sounds like a cracked circuit board.
