Dryer Controls; Timer/Accumulator - GE DCB330EY Technical Service Manual

Dryer Controls

To access the dryer controls, disconnect power and
remove the four Phillips screws at the top of the
switch trim, remove the screws and the switch trim
adapter (shown in illustration below). Grasp the trim
at the top and pull forward. Three tabs at the bottom
fit into slots on the top panel.
Temperature Selector Switch
The temperature selector switch, allows the
customer to select different temperature settings for
drying. The switch contains a 3K ohm resistor on
the electric model and a 2.4K ohm resistor on the
gas model. On the "Medium" setting, the selector
switch activates a control thermostat bias heater,
which is in series with the resistor on the switch. To
check the switch, disconnect power, remove the
wires from the switch and check for continuity. With
the switch set on
"Regular" setting, there
should be continuity
only between terminals
1 and 2. On the
"Medium" setting, there
should be continuity
only between terminals
3 and 4. On a "Fluff"
setting, there should be no continuity between either
set of terminals.
Timer
The timer is an electromechanical control with a 115v
drive motor. On a timed cycle, the timer motor
receives 115 volts continuously for the number of
minutes selected for the cycle. The timer/
accumulator assembly consist of a mounting bracket,
timing motor, snap switch, timing cam, drive (timing
cams) coil spring(pawl), torsion spring (rachet asm),
amd coil spring (index lever). The timing motor is
115V-60HZ, and runs at 1/180 R.P.M. It is shipped
from the factory with a 45 minute cycle time. This
can be changed by ordering a different motor.
(specify voltage, frequency, and speed.) from
Greenwald Industries. See sample parts catalog
pages for timer section for full address.
