Hello, I’m Nathan, and I’ll be assisting you today.
Sorry to hear that you’re having trouble with this but I’ll do my best to help you out.
I can help you with finding parts, if you'd like. On average, you'd be looking at a $100 board, and another $50-100 to have your man install it.
For a unit this age, I would not consider it worth repairing - you could buy a brand new model with updated features and a fresh warranty for about the same amount you'd spend to repair it.
If you'd like the part info, just let me know the full model number of your opener.
If you have any other questions, just let me know. Otherwise, please take a moment to rate my service using the stars at the top of the page; hopefully I have earned 5 Stars. I also invite you to contact me directly with any future support needs at http://bit.ly/1QwLxGh and ask for Nathan.
Thank you, ***** ***** a nice day,
