4. Using a multi-meter, test resistance between
the two heater coils. This should read
approximately between 36.2
W
(ohms) to 40.3
W
(ohms). If open, check the heater harness
for damage. If not damaged, replace the
heater assembly.
Heater Assembly Removal
1. The control panel, top panel, front panel,
front drum support and drum will need to be
removed (see
Control Panel and Front RJ45
Access
,
Top Cover
,
Front Panel
,
Front
Drum Support
and
Drum
sections of this
service guide).
2. Disconnect the harness connectors from the
heater assembly and the thermostats.
3. Remove two 1/4-inch hex-head screws
securing the heater assembly to the dryer
base.
Burner Assembly
The burner assembly consists of the gas valve,
burner, and inlet pipe.
To convert the dryer from natural gas to LP gas,
the burner assembly must be replaced. The
burner cannot be converted to LP gas. Refer to
LP Conversion Kit WE25M87.
The burner assembly has a gas valve that utilizes
three coils. A double coil (safety and booster coils
combined) and a single main coil are located on
top of the gas valve in front of the combustion
chamber opening. All coils can be replaced
separately.
Gas Valve Diagnosing
Access the gas valve by removing the dryer
drum (See
Drum Removal
section of this guide).
Check coil resistance at the gas valve at the
specified terminal. The gas valve coil assembly
approximate resistance values are:
•
Safety Coil Terminals
: 1,400
W
• Booster Coil Terminals
: 580
W
• Main Coil Terminals
: 1,300
