Some mechanic in the past removed the connections from it and bypassed the
auxiliary fan control circuit with a jumper wire. This switch is located at
the top of the receiver-dryer, has a red body, black heat-shrink on the two
leads, and male spade-lug connectors.I was told that it is a pressure
switch, but I think that the fan is really controlled by temp.
So if anyone knows at what temp the switch is calibrated to close (its
open now at room temperature), I could heat up the sensor, and using my
thermocouple temp meter, see if it is really bad or not. I am converting to
R-134, but I can't see how the temp. for fan control would be different from
what would be needed for R-12.
Thanks in advance.
