On the system there is a pressure sensor and a temperature sensor. I am
assuming that the pressure sensor is to prevent the compressor from running
if the refrigerant level gets too low. The temperature sensor must turn on
the fan when the temperature gets too hot to condense the refrigerant. Does
any one know what the pressure and temperature needs to be to switch the
Since the condensation temperature is lower on R134 than R12, are there
better sensors to use that the original ones?
