WARNING!
To avoid possible electrical shock,
personal injury or death, disconnect
the power before servicing.
If no voltage is registered to the coil,
check the operation of the reversing
relay and the continuity of the
connecting wires.
If voltage is registered at the coil, tap
the valve body lightly while
switching the system from HEATING
to COOLING etc. If this fails to cause
the valve to switch position, remove
the coil connector cap and wiring
and test the continuity of the valve
coil. If the coil does not test
continuous replace it.
If the valve is inoperative, replace.
Sound Level
Noise complaints are frequently
caused by a faulty installation.
Sources of actual noise may be
traced to operational components,
tubing vibration, or misalignment of
case or sleeve with chassis.
Component Replacement
Replacement of the compressor,
evaporator, condenser, capillary
tubes and reversing valve must be in
accordance with accepted service
practices. These procedures include
a complete evacuation of both high
and low sides, and changing of both
strainer and capillary tube whenever
the refrigerant system is opened.
Before replacing a component in the
sealed system, make sure that the
cause for complaint does not lie in
the electrical circuit, control,
overload or is due to some other
reason. The serviceman must be
familiar with the operational
characteristics of the product and
should not jump to conclusions.
Drain Pan Valve
(Heat Pump Models Only)
The drain pan valve operates to
remove condensate from base pan.
This is a thermal operated device
that opens at 50°F and closes at 60°F.
