FRYER TROUBLESHOOTING GUIDE
All service (repairs or part replacement) must be performed by a qualified Service Agency.
REMEDY
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
volume and pressure.
3 . Adjust the pilot valve (part of
the gas safety valve) to in-
crease the flame size: Un-
screw and retain the large
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 thermopile.
6 . Check for, and repair, any dam-
aged high-limit thermostat wir-
ing . Otherwise, test the high-
limit thermostat by bypassing
the high-limit thermostat (black
and blue wires) at the gas con-
trol valve with a jumper wire.
Next, perform the Lighting Pro-
cedure, to check whether the
pilot flame lights. If the pilot
flame lights and stays lit, the
high-limit thermostat has failed
and must be replaced.
CAUTION: DO NOT return
the fryer to normal operation
with its high-limit thermostat
bypassed.
7 . Replace the gas control valve.
CAUSE
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 pile.
4 . Pilot flame ‘wavering’ (being blown about
by a draft).
5 . Improper thermopile output voltage (must
be at least 180 millivolts, measured at the
thermocouple junction block).
6 . High-limit thermostat problem has shut of
f
the gas.
7. Gas control valve has failed.
PROBLEM
Pilot flame does no
t
stay lighted.
