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.

(5) Lift gas valve and mounting bracket from
base and carefully remove through access
door opening.
NOTE: The holding coil, booster coil and secondary
coil can be replaced individually or in a kit. Refer to
the parts section of this manual for the correct part
numbers.
To Test Gas Valve Coils:
1. Disconnect valve wire harness at molex plug,
igniter wires at disconnect block and sensor
wires from sensor control.
2. Set test meter to read OHMS and put meter
probes to terminals as follows: (Refer to
Figure 15.)
a. Location “A” (black and blue, 115 Volt
supply wires). If reading is 567 to 697
Ohms, all of the coils are okay. If reading is
1100 to 1430 Ohms, then move meter
probes to location “B”.
b. Location “B” (blue and white wires to
sensor). If reading is 1640 to 2010 Ohms,
the secondary coil is open and coil must be
replaced. If reading is 630 to 7770 Ohms,
then move meter probes to location “C”.
c. Location “C” (black and red wires to
igniter). If reading is 540 to 660 ohms,
holding coil is open and coil must be
replaced. If reading 1730 to 2120 Ohms,
booster coil is open and must be replaced.
NOTE: Test procedure can be performed on
workbench if gas valve, igniter, burner tube and
burner housing are removed from dryer.
