SERVICING
1. Disconnect power to air handler or modular blower.
NOTE: Motor contains capacitors that can hold a charge for
several minutes after disconnecting power. Wait 5 minutes
after removing power to allow capacitors to discharge.
2. Disassemble motor as described in steps 2 through 4
above.
3. Locate the 3-circuit harness from the motor. Using an
ohmmeter, measure the resistance between each motor
phase winding. The resistance levels should be equal. Re-
place the motor if the resistance levels are unequal, open
circuited or short circuited.
4. Measure the resistance between each motor phase wind-
ing and the motor shell. Replace the motor if any phase
winding is short circuited to the motor shell.
5. Reassemble motor and control/end bell in reverse of
disassembly. Replace blower assembly into air handler or
modular blower.

S-16H ECM CFM ADJUSTMENTS DVPTC/MBVC

This section references the operation characteristics of the
DVPTC/MBVC models. The MBVC models utilize an integrat-
ed air handler control. The air handler control provides ECM
blower motor control and includes all dipswitches necessary to
set up the cooling, heat pump and electric airflow characteris-
tics.
The control has three banks of dipswitches: a bank for cooling
airflow and trim adjustment, a bank for selecting one of (4) en-
hancement profiles and enabling dehumidification, and a bank
for selecting the installed electric heater kit size. Adjustments
are made by selecting the appropriate ON/OFF combinations
of the dipswitches. The dipswitches along with their functions
are shown in the figures below.

Dehumidification Disable/Enable Dipswitch - Reduces cooling
airflow by ~ 15% when enabled AND when used with a hu-
midistat (such as DEHUM1). Airflow is reduced when a call for
cooling is present and the humidistat is open.
