“ON” indicator is lit, but the A/C compressor never
comes on in either the LOW COOL, HIGH COOL, or
AUTO COOL mode, even when the set point control is
set to its lowest (cool) position. In the HEAT mode, the
furnace works properly in conjunction with the set
point control.
A. Slide the test switch on the control module towards J2.
A/C1 compressor and high fan should turn on.
If
NOT:
1) Check to make sure that the leads on PC2 are
connected to their corresponding function at
the A/C1 unit. The wire colors may or may not
match. It is likely that the “common” and ”high
fan” leads are reversed.
2) Check the continuity of the ”Comp Relay” lead
between the control module and the front A/C
unit.
B. Slide the test switch on the control module towards J3.
A/C2 compressor and high fan should turn on.
If
NOT:
1) Check to make sure that the leads on PC3 are
connected to their corresponding function at
the A/C2 unit. The wire colors may or may not
match. It is likely that the ”common” and ”high
fan” leads are reversed.
2) Check the continuity of the ”Comp Relay” lead
between the control module and the A/C2 unit.
C. Check to make sure that the connector, PC1B, from the
current sensor is plugged into J1, pins 1 and 2 and that the
120 VAC supply lead to the 30 Amp breaker in the
distribution panel passes through the hole in the current
sensor.
If
OK
then:
Unplug the current sensor from the control module
and measure the resistance across the leads to
the current sensor. The resistance should be
approximately 40 Ohms.
If
NOT:
Replace the current sensor.
