SYSTEM CONTROL SWITCH - TEST (See Figure 18)
Disconnect leads from control switch. Turn control to position
being tested. There must be continuity as follows:
1. "Off" Position-no continuity between terminals.
2. "Lo Cool" Position-between terminals "C" and "3", "C2"
and "2", "LO" and "M/S", "AR" and "5".
3. "Med Cool" Position-between terminals "C" and "3",
"C2" and "2", "M" and "M/S", "AR" and "5".
4. "Hi Cool" Position-between terminals "C" and "3", "C2"
and "2", "H" and "M/S", "AR" and "5".
5. "Hi Heat" Position-between terminals "C" and "1", "C2"
and "4", "H" and "M/S", "AR" and "5".
6. "Med Heat" Position-between terminals "C" and "1",
"C2" and "4", "M" and "M/S", "AR" and "5".
7. "Lo Cool" Position-between terminals "C" and "1", "C2"
and "4", "LO" and "M/S", "AR" and "5".
8. "Fan Only" Position-between terminals "L1" and "M".
SYSTEM CONTROL SWITCH KS, SS, KM, SM, KL, SL
Models (See Figure 19)
A five position control switch is used to regulate the operation
of the fan motor and compressor. The compressor can be
operated with the fan operating at low, medium or high speed.
The fan motor can also be operated independently on medium
speed. See switch section as indicated on decorative control
