I found them from web by comparing reviews. They came home for ac problem. The gentleman told the control board had to be changed. He quoted 612 usd. Told would run. he asked and got the half and placed order. He came next week. It was a simple card. Changed the card but ac was still not working than he claimed otside unit were not functioning. Than he said this is an old system and needs to replace the whole in and outside units. Before him, the switch/sensor was working but now its not working. He put damaged fuse on the board and the connections were wrong. I just called another 2 companies. Both Said same, the connections were wrong and the fuse was broken. Even Sanders guy did not ask to leave the old card and took with him without asking. Now theydont care and refund our money.
