My Ruud Achiever outside compressor is stating and stopping. The fan turns normally for 3-4 seconds and then it cycles over and over. The unit is 5-6 years old. How do I diagnose this before calling in the pro?
Your unit sounds like it is short cycling on low pressure. find the cylindrical thing on the larger line in the unit.it will have two low voltage wires coming out of it. trace those two wires back to where they go and turn off the unit so you can install a jumper across them. turn on the unit and see if it keeps short cycling or if it is running more normal. if it runs more normal then you are most likely low on freon or a slight chance of an airflow restriction
