how AC clutch cycles? AC thermostat checking?
Wed, 2 Jul 2003 12:38:33 -0400
The temperature sensor and "thermostat" are one in the same. There is a lit=
tle phillips-head screw on the top of it. Turning it counter clockwise lowe=
rs the temp at which it kicks out the compressor. Mine was at 45*, it took =
1=2E5 turns to get it to 38*F, but others have reported that it only too th=
em 1/4-1/2 to get it down to the 30s, so do it 1/4 turn at a time and allow=
plenty of time for it to come down between turns...
