Idler Assembly - GE GTUP270EMWW Technical Service Manual

Idler Assembly

The idler assembly maintains proper tension on the
belt to minimize belt slippage. The idler assembly
consists of an idler pulley that rotates on an idler
arm. The pulley is retained on the arm using a cap
nut. The idler arm is positioned on the dryer chassis
and inserted in a slot in the motor base plate. The
assembly is located to the left of the motor.
To remove the idler assembly:
1. Remove the drum. (See
WARNING: The idler arm is under high tension. To
prevent injury, do not let the idler arm snap back.
2. Release tension on the idler assembly by
unlocking the idler arm from the top right corner
of the motor bracket.
3. Remove the idler arm from the slot in the motor
base plate.

Motor and Blower Assembly
The motor is a single-speed, dual-shaft, 1/4-hp,
1725-rpm motor with an automatic reset overload
protector. The overload protector is an internal
component of the motor and cannot be replaced
separately. The motor contains a centrifugal switch
that serves 3 purposes: It disengages the motor
start winding (M6), engages the motor run winding
(M5), and closes the circuit contacts (M1 to M2) for
the heat source.
Motor resistance values:
Start winding = 4.6 ohms
Run winding = 2.5 ohms
To remove the motor and blower assembly:
1. Remove the drum. (See
2. Remove the Phillips-head screw and the outlet
control thermostat from the blower housing.
3. Remove the idler pulley assembly from the
motor bracket. (See
4. Disconnect the motor wire harness.
5. Remove the motor harness wire tie from the
dryer chassis.
6. Disconnect the wires attached to the belt switch.
