is not illuminated.
A.
ON/OFF switch is off.
A.
Turn ON/OFF switch on.
ON/OFF switch is on,
but the switch light is
not illuminated.
A.
No voltage at switch.
A.
Ensure line voltage is present at
the switch.
ON/OFF switch is on
and the switch light is
illuminated, but there
is no output to gas
valve.
A.
Drain microswitch circuit (filter-
equipped units) is open.
A.
Ensure drain valve is fully closed
and microswitch is functioning.
Replace microswitch if defective.
B.
Voltage is present at ON/OFF
switch, but continuity of the switch
in ON position is not "0.”
B.
ON/OFF switch is defective.
Replace switch with a known
working switch.
C.
Continuity of thermostat is not "0"
(oil temperature is at least 15°F
below electronic thermostat
setting).
C.
Thermostat(s) is/are defective.
Replace defective thermostat with
a known working thermostat.
D.
Gas valve is suspect.
D.
Go to "No burner flame" section.
No burner flame.
C.
Gas valve is known to be good, but
there is not 24 VAC (120VAC on
systems so equipped) at the gas
valve terminals.
D.

still in frypot) for damage. Replace
if bent, dented, or cracked.
Inspect leads for fraying, burning,
breaks, and/or kinks. If found,
remove and replace thermostat(s).
Remove leads from terminal block,
allow oil to cool 15°F (8°C) below
thermostat setting, and check
continuity. If continuity is not "0,”
then thermostat has failed.
Replace thermostat(s).
Fluctuating or erratic
lighting of burner
flame.
A.
Incoming gas supply pressures are
not within range [Natural- 6-14"
W.C. (1.49-3.49 kPa); Propane- 11-
14" W.C. (2.74-3.49 kPa)]
A.
Inspect gas supply to fryer. Repair
and/or replace faulty components
