Section 7 Test Procedures
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
56. ELECTRICAL CIRCUIT TO IGNITION
SYSTEM – SILICON CARBIDE IGNITION
a. While supporting the access panel, remove two
screws from bottom edge of access panel. See
Figure 5.
b. Gently lower the access panel to disengage
locators from bottom edge of front panel. See
Figure 12.
c. Close main gas shut-off valve.
d. Remove valve wire harness disconnect block
from the holding and booster coil. See
Figure 39.
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. See Figure 38.
Meter should register line voltage in all Fabric
settings, except FLUFF which should read
“zero” VAC.
g. If meter does not read line voltage in step “f”,
check motor switch, thermostats, fabric switch,
or timer.

57. GAS VALVE COILS CHECK – SILICON
CARBIDE IGNITION
a. While supporting the access panel, remove two
screws from bottom edge of access panel. See
Figure 5.
b. Gently lower the access panel to disengage
locators from bottom edge of front panel. See
Figure 12.
c. Close main gas shut-off valve.
d. Remove disconnect blocks from gas valve
e. Set test meter to read Ohms and put meter
probes to terminals as in Figure 39, and in the
following chart.

supply line to the gas dryer and disconnect
the electrical power unless gas or power
supplies are required to perform test
procedure.
