Ordered the sensor parts which I thought was the problem, but it was a wiring issue in the system. We hooked up the new sensors anyway and they are working great. You get five stars......so far.
Past reviews I usually take with a "grain of salt" but these guys shipped so fast it was impressive. Everything was exactly as presented online. One of the quickest "fixes" I have had.
The door control worked perfectly with my new +2.0 security Chamberlain door opener. It was easy to install, inexpensive and well made. The customer service was outstanding.
