Warning
7. Locate the 3-circuit connector in the control/end bell. Using an ohmmeter, check the resistance
between each terminal in the connector. If the resistance is 1 M
Ω
or greater, the control/end bell
is functioning properly. Replace the control/end bell if the resistance is lower than 1 M
Ω
.
8. Reassemble motor and control/end bell in reverse of disassembly. Replace blower assembly
into air handler or modular blower.
Motor Checks
HIGH VOLTAGE!
Disconnect ALL power before servicing or installing. Multiple power sources may be present.
Failure to do so may cause property damage, personal injury or death.
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. Replace the motor
if the resistance levels are unequal, open circuited or short circuited.
4. Measure the resistance between each motor phase winding 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.
