GRILL TROUBLESHOOTING
PROBLEM AREA: WHAT TO DO: USEFUL NOTES:
Grill will not operate
Grill still will not
operate, (Electrically
operational -
Steps 1-8 OK)
CHECK 1) the Electrical / Gas Supply as out-
lined in the General Instruction section.
2) Remove Grill racks and the radiant
tray- visually check for igniter breaka ge
3) Remove Valve Panel (see General
instructions and note removal of "Red" screw
behind control knob- not on all units)
4) 120 V supplied to "C"(common) ter-
minal of Valve Switch?
5) Disconnect power, Remove wire from
"NC"(normally closed) terminal & check for
continuity between "C" and "NC" when valve
is rotated to the "ON" position. If none is,
switch positioned so that the tab on the valve
stem activates the switch when the knob is in
"OFF" (thus de-energizing to NC contact) ?
Test the switch manually, if non-operational,
remove / replace.
6) If switch is OK, Remove the wires
from the Thermal Valve and check for continu-
ity between the two (2) terminals on the face of
the valve. If none, remove / replace.
7) If the Thermal Valve is OK, Remove
the wires from the Grill Igniter and check the
igniter leads for continuity. If none, remove /
replace igniter.
8) If the Igniter is OK, Check the
Neutral Return Wire for continuity to the neu-
tr al (white) wire of the power supply cord.
1) Verify Gas supply to the unit, Loosen
tubing supplying gas from the manual "on-off"
valve to the Thermal Valve at the Thermal
Valve. Quickly turn manual valve On, then Off
and listen closely for the sound of flowing gas.
If gas is not flowing, shut off gas supply, and
check the tubing for blockage.
NOTE:-Ensure at
the supply source
that the live and neu-
tral wires are not
reversed ( If they are,
this would not be
covered under war-
ranty)
