Re: Help! A/C techs!

is the high pressure cut off and low pressure cut off all in 1 switch?
is it connected to the accumulator? if so why is it necessary to replace the low pressure switch?

high pressure cut off switch goes on the high pressure side of the a/c not the low side.

check wiring diagrams and if power goes from a/c panel to low pressure switch (if ok) it goes to compressor clutch. see if you have power going to low pressure switch.
