To reduce the risk of electric shock, fire, explosion, serious injury or death:
• Disconnect electric power to the dryer(s) before servicing.
• Close gas shut-off valve to gas dryer(s) before servicing.
• Never start the dryer(s) with any guards/panels removed.
• Whenever ground wires are removed during servicing, these ground wires must be
reconnected to ensure that the dryer is properly grounded.

WARNING
36. Electrical Circuit To Ignition
System (Gas Models)
a. While supporting the access panel, remove two
screws from bottom edge of access panel.
b. Gently lower the access panel to disengage
locators from bottom edge of front panel.
c. Close main gas shut-off valve. Refer to
Figure 11
.
d. Remove valve wire harness disconnect block
from the holding and booster coil. Refer to
Figure 31
.
e. Plug dryer power cord into wall receptacle, and
start the dryer in a heat setting (refer to the
Operating Instructions supplied with dryer).
f. 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 30
.
Meter should register line voltage in all
temperature settings, except FLUFF (NO
HEAT) which should read “zero” VAC.
g. If meter does not read line voltage in step “f”,
check motor switch, thermostats, fabric switch,
accumulator, or timer.
37. Gas Valve Coils Check (Gas
Models)
a. While supporting the access panel, remove two
screws from bottom edge of access panel.
b. Gently lower the access panel to disengage
locators from bottom edge of front panel.
c. Close main gas shut-off valve. Refer to
Figure 11
.
d. Remove disconnect blocks from gas valve
coils.
e. Set test meter to read Ohms and put meter
probes to terminals shown in
Figure 31
, and in
the following chart.
Silicon Carbide Ignition:
COIL TOLERANCE READINGS
Silicon Nitride Ignition:
Both coils should read between 2400-2800
Ohms.
NOTE: If meter registers any other readings than
those listed above, the respective coil(s) should be
replaced.
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.
