3. Burner Circuit. In approximately 30 seconds, the igniter at-
tains ignition temperature and ignition is made. The heat from
the burner flame causes the sensor contacts (located on burner
housing beside the igniter) to open. A circuit is then complet-
ed through the secondary valve coil, opening the valve and al-
lowing gas to flow.
4. Momentary Power Interruption. Upon resumption of pow-
er, sensor contacts will still be open, permitting secondary
valve to open. However, with the secondary coil in the circuit,
the booster coil cannot draw enough current to open the split-
coil valve. When sensor contacts do reclose, the secondary
valve will close, and the burner system will be in the normal
pre-ignition circuit.
5. Flame Failure. In case of flame failure, the sensor contacts
will re-close in about 45 seconds. This will close the secon-
dary valve and the burner system will be in the normal pre-
ignition circuit.
6. Ignition Failure. If flame is not established as sensor contacts
open, secondary valve will remain open until sensor contacts
re-close. Sensor will continue to recycle the igniter and secon-
dary valve (about once per minute) until ignition is made or
dryer is turned off.
Electrical Circuit Ignition System (Gas
Models)
1. While supporting the access panel, remove two screws from
bottom edge of access panel.
2. Gently lower the access panel to disengage locators from bot-
tom edge of front panel.
3. Close main gas shut-off valve. Refer to Figure 4 .
4. Remove valve wire harness disconnect block from the hold-
ing and booster coil. Refer to Figure 12 .
5. Plug dryer power cord into wall receptacle, and start the dryer
in a heat setting (refer to the Operating Instructions supplied
with dryer).
6. Set test meter to read AC voltage and apply meter probes into
terminals on the dryer harness plug that would correspond to
terminals “1” and “2” on the coil.
Figure 10 . Meter should
register line voltage in all Fabric settings, except NO HEAT
which should read “zero” VAC.
7. If meter does not read line voltage in step “f”, check motor
switch, thermostats, fabric switch, accumulator, or timer.

Gas Valve Coils Check (Gas Models)
WARNING
To reduce the risk of fire, explosion and electric
shock, close the valve in the gas supply line to the
gas dryer and disconnect the electrical power unless
gas or power supplies are required to perform test
procedure.

1. While supporting the access panel, remove two screws from
bottom edge of access panel.
2. Gently lower the access panel to disengage locators from bot-
tom edge of front panel.
3. Close main gas shut-off valve. Refer to Figure 4 .
4. Remove disconnect blocks from gas valve coils.
5. Set test meter to read Ohms and put meter probes to terminals
shown in Figure 12 , and in the following chart.
Meter probes to terminals: Meter should read:
Holding Coil – Terminals 1 &
2 1365 ± 230 Ohms
Booster Coil – Terminals 1 &
3 560 ± 100 Ohms
