Pilot flame does not
stay lighted.
PROBLEM CAUSE REMEDY
Pilot (piezo-electric)
pushbutton igniter does
not light the pilot flame.
1. Electrode of igniter out of position or
dirty/sooty electrode.
2. Loose spark wire; loose igniter nut.
3. Piezo-electric igniter does not generate a
spark.
1. Move electrode within 3/16” of
pilot burner tip. Clean the
electrode.
2. Check spark wire connection at
the igniter nut and make sure
the connection is tight.
3. Replace igniter mechanism
(portion with pushbutton).
All service (repairs or part replacement) must be performed by a qualified Service Agency.
1. Clean the pilot burner. Perform
the Lighting Procedure.
2. Measure the gas supply pres-
sure.
Contact your local gas supplier
to obtain adequate gas supply
pressure.
3. Adjust the pilot valve (part of
the gas control valve) to in-
crease the flame size: Un-
screw and retain the slotted
threaded cover; turn the pilot
valve adjustment screw two
turns counterclockwise;
reinstall the threaded cover.
4. Block or redirect the draft, to
keep the flame burning steadily.
5. Replace the thermocouple.
6. Check for, and repair, any dam-
aged high-limit thermostat wir-
ing. Test the high-limit thermo-
stat by disconnecting the ther-
mocouple at the gas control
valve. Also, disconnect the red
wires to the high-limit thermo-
stat from the gas control valve.
Reconnect the thermocouple;
then, perform the Lighting Pro-
cedure, to check whether the
pilot flame lights. If the pilot
1. Dirty/sooty pilot burner.
2. Low gas supply pressure [less than 6”
W.C. for natural gas; (11” W.C. for pro-
pane) when
all other gas-powered equip-
ment is operating].
3. Pilot flame too small to heat thermo-
couple.
4. Pilot flame ‘wavering’ (being blown about
by a draft).
5. Improper thermocouple output voltage
(must be at least 10 millivolts, measured at
the thermocouple junction block).
6. High-limit thermostat problem has shut off
the gas.
