Remote doesn't open garage door. If I press the button within the garage, it will open or close the door. The battery in the remote is new. The built in car opener doesn't work either. At one point, door would open with the remote for several days and then it wouldn't. This happened on two occasions but now the remote won't open the door. Note: the settings on the door opener and the settings on the remote are the same.

Can the receiver's electronic receiving component be replaced instead of having to replace the whole door opener mechanism?
