The Coromaster 2000 does not operate off limit switches. It has a quarter-revolution optical pulse counter. To re-program the open and close limits do the following: Ensure that the door is open at least a couple of feet. Press the reset button once or twice Short out pushbutton and common and hold until close limit and then release. Door should stop at your new close limit. Wait 5 seconds. Short out pushbutton and common and door will open. Hold the short until open limit and then release. Limits should now be set.
A friend of mine does garage door repair in Naperville, IL. Maybe give him a call.
Do you know how much it would cost for a garage door replacement in Plano?

Can anyone fix or replace the pc board on a caroma coromaster 2000
There are probably switches mounted to the rail that the door linkage runs on. Try moving those to wear you want the machine to stop when the carriage hits them, and make sure the wires from those are connected to the garage door opener power unit.
there is 2 screws (no heads, only slots) at the bottom of the motor that need to be ajusted
