Other Possible Faults
No gas to burner.
• The gas valve should open at the same time as the igniter sparks.
If there is no gas to the burner when this occurs check the
solenoid coils for continuity.
• Check that the gas pressure is present at the test point when the
spark is being generated.
• Check that there is gas to the inlet of the gas control.
Fuse blowing.
• If the fuse continues to blow check the solenoid coils for a signs of
them being shorted.

room fan (circulation
fan) pressure signal has
been interrupted.
Check the fan for dust build up and lint. Check that the
room air fan is spinning. Check that the pressure tubes are
connected correctly and not pinched or kinked. The black
tube should run from the black side of the pressure switch
to the bottom tapping on the fan venturi. The clear tube
should go from the light side of the pressure switch and to
the top tapping on the venturi. Make sure that the pressure
switch wires are connected correctly. One wire should be
to C (Common) and the other should be to NO (Normally
Open). If it still doesn’t work after checking the above,
change the pressure switch.
