I wanted to know if there is an alternative to pn 0008208010 which is the stock 6mm 127 degree farenheit temp switch on the receiver that activates the aux fan. I want the fan to activate at a lower temp but don't want to wire it to always run when the compressor is on.

Thanks for the help,

I haven't seen anything. I agree that the fan turns on a bit late to keep cool when stuck at a red light. But, if <127 F, it would be running all the time in our hot summers, even when not needed (AC clutch off). I do have several junkyard temp switches. I tested them all and wrote the "switch-on" temperature on each w/ a Sharpie. All were within +/-2 C. I recall ~60 C, but don't quote me.

Yeah Bill, we are on the same page. With our hot humid days, the aux fan needs to start sooner to keep the condenser temp from climbing to an "un-coolable" level when at an extend stop. Only once has my aux fan come on from heat soak. I was sitting at a stop light, it was about 105 degrees in the sun and this was before I fixed my A/C and didn't even have a belt on the seized compressor but my aux fan came on just from ambient under hood temps.

I am going to purchase an adjustable fan controller and set the trigger temp to 90F (about 30 degrees lower than stock). I really want to use the stock location on the drier but I would need to sacrifice a temp switch to hold the new sensor in its place. I'll probably stick the new sensor somewhere on the condenser for the same reading.

Very interested in your results with the adjustable fan speed controller. Please keep us updated once you get it working!
