TROUBLESHOOTING
Continued
OBSERVED PROBLEM POSSIBLE CAUSE REMEDY
When ignitor button is pressed on the
remote or touch pad, the pilot sparks
but there is no igni ion.
1. Gas supply turned off or equip
-
ment shutoff valve closed
2. Air in gas lines.
3. Thermocouple circuit between
the control valve and he control
module is open.
4. No gas to the ods pilot
5. Depleted gas supply (propane/LP
only)
6. Valve cable is disconnected or
broken.
7. ODS pilot is clogged
8. Gas regulator set ing is not correct
1. Turn on gas supply or open equip-
ment shutoff valve.
2. Continue turning he burner sys-
tem ON and OFF. Repeat igniting
operation un il air is removed.
On first time ignitions, air in the
lines is common and it is not
uncommon to repeat he ignition
sequence 10 to 15 times before
enough gas is at the ods pilot for
it to light.
3. Check the thermocouple con-
nection at the control valve and
also at the control module. The
thermocouple connection at the
control valve should be hand
tight plus 1/4 to 1/2 turn. You
should not be able to loosen
the thermocouple at the control
valve with your hand. Check the
thermocouple terminal connection
at the control module. If it is loose,
remove it with needle nose pliers,
using he pliers, slightly close the
terminal's opening and reinstall on
to he control module.
4. While the pilot is sparking, check
for gas flow at the ods pilot. If flow
is present, try to light the pilot with
a long reach lighter. If it will not
light but the flame is disturbed,
air is in the line. Cycle through
the ignition sequence to clear the
line of air until gas is present. If no
flow is present at the gas valve,
check to see all shut off valves
are open. Verify proper pressure
is supplied to the valve. Exces-
sive pressure can lock out the
appliance's regulator. Also check
to see that the wiring harness
from the control valve is properly
connected at the control module.
The wiring harness connection
housing can be identified by it's
blue connector housing.
5. Contact local propane/LP gas
company.
6. Connect valve cable correctly
7. Clean ods pilot (see Cleaning and
Maintenance , page 34) or replace
ods pilot assembly.
8. Replace gas regulator
