Dryer Test Procedures
To reduce the risk of electric shock, fire, explosion, serious injury or death:
• Disconnect all electric power to the machine and accessories before servicing.
• Close gas shut-off valve to gas dryer before servicing.
• Never start machine with any guards/panels removed.
• Whenever ground wires are removed during servicing, these ground wires must
be
re
connected to ensure that the machine is properly grounded.
• Washer motor not grounded! Disconnect electric power before servicing motor.

WARNING
47. Electrical Circuit To Ignition
System (Gas Models)
a. While supporting the access panel, remove two
scre
ws 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
Figur
e 9.
d. Remove valve wire harness disconnect block
from the holding
and booster coil. Refer to
Figur
e 15.
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
met
er probes into terminals on the dr
yer
ha
rness plug that would correspond
to
terminals "1" and "2" on the coil. Refer to
Figu
re 14. Meter should register line
voltage in
all cycle
s, except NO HEAT which should
read
“ze
ro” VAC.
g. If meter does not read lin
e voltage in step “f”,
check motor switch, thermos
tats, fabric sw
itch,
acc
umulator, or timer.
48. Gas Valve Coils Check (Gas
Models)
a. While supporting the access panel, remove two
sc
rews from bottom edge of access pa
nel.
b.
Gently lower the access panel to dise
ngage
lo
cators from bottom edge of front panel.
c. Close main gas shut-off valve. Re
fer to
Figur
e 9.
d. Remove disconnect blocks from gas va
lve
coils.
e.
Set test meter to read Ohms and put meter
probes to terminals shown
in Figure 15, and
in
th
e following chart.
COIL TOLERANCE READINGS
NOTE: If meter registers any other readings than
those listed above, the respective coil(s) should be
replaced.

Meter probes to terminals: Meter should read:
Holding Coil – Terminals 1 & 2 1365 ± 25 Ohms
Booster Coil – Terminals 1 & 3 560 ± 25 Ohms
Secondary Coil – Terminals 4 & 5 1220 ± 50 Ohms
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.
