Hey just wanted your input
Just taken on a apprentice from another engineer. He is kind of set in his ways ie put gauges on - low on gas so top up no rise in suction pressure so expansion valve is blocked is basic of his findings for a job we done .
So my question to you is how do you go about fault finding a cellar cooling system and testing/inspecting a expansion valve?
I want to show him this thread and show him he doesnt neccessarilly need guages to fault find and its not my way vs another , more his hands eyes and ears are just important as guages are and that he will probably find a way that works for him completely different from who trained him anyway
Thanks in advance
