Gas Valve
If no heat, with the dryer running and a heat cycle selected, check for 120 VAC to the gas burner assembly
from J2 RED wire to the BROWN wire on the J8. Approximate amperage draw of 3.5 amps can be checked
from the RED wire on the J2 connector.
Also check between J4 and J2. If relay is closed, no voltage should be present when calling for heat. If it is,
replace the board.
If voltage is present, disconnect power from the dryer. Check igniter, thermostats, fl ame detector, gas valve
coils, motor switch, harnesses, and connectors.
