The confusion is b/c the parts catalogs refers to high side aux fan sw as a temp sw, when it is a pressure sw..I think they do that to differentiate that sw from the actual comp pressure sw , which they do properly refer to as a pressure sw, whereas the aux fan sw does control the heat coming off the condenser, but that does not justify calling it a temp sw [ the specs are in Bar, not C , so I don't what they are smoking].. you will notice that they cover that mistake by adding notation of the actual electrical function in the part discription along with the pic of each sw..They now say "Aux fan cut-in w/pigtail for ac" and "Compressor cut-out " for the other.
Confusing, but that at least helps.
..I alway refer to aux fan sw as the one with the 'Pigtail leads" to aid anyone using my diagnostic post..seems to work most of the time. I also tell them when jumping it for low fan test, to leave the wire connectors on the sw and just peel back the white connector sleeves at the pigtail to jumper there b/c , for unknown reason to me, I get a lot of guys who unplug those connectors for jumper test and then they jumper the wires on the sw side, instead of the circuit side..don't know how they think that is going to register back to the relay, but they do it all the time,so I have to have them leave the connections intact so I don't go on a goose chase..it works for me.
