D To A Boards

Gas valve will not modulate but pilot flame lights
When replacing your D to A board it is important to know what version of software is running in the dryer controller. For versions with a date code of 8709H and earlier it is necessary to cut the following resistors on the new D to A board with the part number listed.

R20 R13
R21 R19
R23 R26

Failure to cut these resistors will result in symptoms wherein the display shows the gas valve to be full open (at position 255) when in reality there is only a very small flame. If these symptoms exist, cut the resistors.
