A service person was easy to schedule and showed up when expected. Quickly analyzed the problem and located a replacement circuit board for an old system locally. Picked up the circuit board, installed and tested perfect! He identified that the failed component on the board was a relay. I was able to final a replacement relay for the board for future back up. The damaged relay had to be de-soldered from the CB and then I soldered in the replacement should that component fail again. My system is working perfectly and I am well pleased.
