Now, as far as operation, we typically take the start up and draw for the compressor and the run amp draw. And as far as the condenser fan, we check the running amp of it and you usually find on the data on the data plate. It gives you basic information of what we're looking for. In the case of the compressor, the maximum running amp should have been 14. Maximum start of amp should have been 68 at.
