I have a high preasure switch that has gone bad on one of my A/C units. Cruise Air 7k btu compressor low is 150 high is 300psi. It had Klixon 325 on it that went south not able to find any of those. I have found Johnson Controls P100cp-166c units online that are 225 on and 325 off I ordered two of these. There is also a Johnson Control P100cp-161c that is 200low and 400psi high but can't locate any of those. Suggestions anyone? A/C guy I know said the 325 high may not be high enough.....
