HUMIDITY CONTROL
When using a Humidstat (normally closed), cut jumper PJ6
on the control board. The Humidstat will only affect cooling
airflow by adjusting the Airflow to 85%.
TWO STAGE HEATING
When using staged electric heat, cut jumper PJ4 on the
control board.
S-16E CHECKING GE X13 TM MOTORS
The GE X13 TM Motor is a one piece, fully encapsulated, 3
phase brushless DC (single phase AC input) motor with ball
bearing construction. Unlike the ECM 2.3/2.5 motors, the GE
X13
TM features an integral control module.
Note: The GE TECMate will not currently operate the GE
X13
TM motor.
1. Using a voltmeter, check for 230 volts to the motor
connections L and N. If 230 volts is present, proceed to
step 2. If 230 volts is not present, check the line voltage
circuit to the motor.
2. Using a voltmeter, check for 24 volts from terminal C to
either terminal 1, 2, 3, 4, or 5, depending on which tap is
being used, at the motor. If voltage present, proceed to
step 3. If no voltage, check 24 volt circuit to motor.
3. If voltage was present in steps 1 and 2, the motor has
failed and will need to be replaced.
Note: When replacing motor, ensure the belly band is
between the vents on the motor and the wiring has the
proper drip loop to prevent condensate from entering the
motor.

S-17 CHECKING COMPRESSOR
WARNING
Hermetic compressor electrical terminal venting can
be dangerous. When insulating material which
supports a hermetic compressor or electrical terminal
suddenly disintegrates due to physical abuse or as a
result of an electrical short between the terminal and
the compressor housing, the terminal may be
expelled, venting the vapor and liquid contents of the
compressor housing and system.
If the compressor terminal PROTECTIVE COVER and gasket
(if required) are not properly in place and secured, there is a
remote possibility if a terminal vents, that the vaporous and
liquid discharge can be ignited, spouting flames several feet,
causing potentially severe or fatal injury to anyone in its path.
This discharge can be ignited external to the compressor if
the terminal cover is not properly in place and if the discharge
impinges on a sufficient heat source.
Ignition of the discharge can also occur at the venting terminal
or inside the compressor, if there is sufficient contaminant air
present in the system and an electrical arc occurs as the
terminal vents.
Ignition cannot occur at the venting terminal without the
presence of contaminant air, and cannot occur externally
from the venting terminal without the presence of an external
ignition source.
Therefore, proper evacuation of a hermetic system is essen-
tial at the time of manufacture and during servicing.
To reduce the possibility of external ignition, all open flame,
electrical power, and other heat sources should be extin-
guished or turned off prior to servicing a system.
If the following test indicates shorted, grounded or open
windings, see procedures S-19 for the next steps to be taken.
S-17A RESISTANCE TEST
Each compressor is equipped with an internal overload.
The line break internal overload senses both motor amperage
and winding temperature. High motor temperature or amper-
age heats the disc causing it to open, breaking the common
circuit within the compressor on single phase units.
Heat generated within the compressor shell, usually due to
recycling of the motor, high amperage or insufficient gas to
cool the motor, is slow to dissipate. Allow at least three to
four hours for it to cool and reset, then retest.
Fuse, circuit breaker, ground fault protective device, etc. has
