Main Board
WARNING: THE CONNECTOR AT THE LCD BACKLIGHT IS OVER 800 VDC. USE APPROPRIATE
TYPE VOLTMETER OR DAMAGE COULD RESULT.
Note: The gas dryer main board differs from the electric dryer main board by the addition of a jumper
plug on the model selector connector (the electric model has no jumper plug). Depending on how the
pins have been jumped will determine what type of gas (natural or LP) the dryer is using.
The LP conversion kit is part number WE25X10014 and consists of the LP model selector and an LP
orifice for the gas valve.
The dryer control performs three checks to determine whether the dryer is an electric, LP gas or natural
gas.
•
Initially, the control looks for a flame sensor. If the flame sensor is detected, the control then looks for
a model selector set for natural or LP gas.
•
If both conditions are satisfied, the dryer will start.
•
The dryer control then monitors temperature based on specific software parameters for each type of
gas. If the temperature is outside of that range, an error is displayed on the LCD display and the
dryer will shut down. (See
