FRYER  TROUBLESHOOTING  GUIDE

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 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 off

the gas.

7. Gas control valve has failed.

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.

7. Replace the gas control valve.
