Hi all, who am I to disagree with the authors of the Kotza refrepair manual. Whilst perusing this great book I stumbled across something on page 29 that seemed to throw a curve ball at me, and I quote:
"If the superheat is too large, the expansion valve will be closed and will allow very little liquid to pass through. As the evaporator contains very little liquid, the refrigerating capacity is small and the change in temp for the air is rather small"
and further on:
"If the superheat is too small the expansion valve opens too much and allows too much liquid to pass through."
Is it me that has got his lines crossed or what??
