Lift master 881LM not working with my Liftmastar Formula I

Lift master 881LM not working with my Liftmastar Formula I. I get one yellow LED blinking light but no Red. It won't Open the garage door. As soon as I plug in my stock control panel it works perfectly. Any help would be greatly appreciated.
