I have an older York Central AC unit. The unit just stopped working. I have replaced the transformer and the fan relay. When I replaced the old relay with the new one the relay does a lot of clicking. Does anyone know why this is happening?
Maybe the original reason for your transformer going out is now appearing. On the other hand maybe you have guessed at the problem and threw some parts at it and it is still not working correctly. Keep guessing eventually you may get it right.
