FRYER TROUBLESHOOTING GUIDE
PROBLEM CAUSE REMEDY
All service (repairs or part replacement) must be performed by a qualified Service Agency.
Pilot flame does not
stay lighted.
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 the 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.
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. [For model 14GSU fryer
ONLY: Press the reset push-
button on the high-limit thermo-
stat control. Perform the Light-
ing Procedure, to check wheth-
er the pilot flame lights. If the
pilot flame stays lit, the high-
limit thermostat has failed and
must be replaced. ]
Pilot (piezo-electric)
pushbutton igniter, if
present, 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).
