TROUBLESHOOTING CHART
ITEM PROBLEMS POSSIBLE SOLUTIONS
1
Main burner will not ignite. Blower is operating; but
gas is not present at the burner.
A. Check the Blower air pressure Switch by temporarily
disconnecting the two (2) air switch wires and
connecting them together. If the
IGNITOR sparks when these
wires are connected, the air pressure switch is defective and it will
have to be replaced.
B. Check the following components and replace if found to be
defective: Gas Control Valve
Hi-Limit Switch
Transformer
2
Electrical power is present at the fryer, but the
Blower is not operating.
A. Blower may have over-heated and shut off on thermal overload.
If this situation did occur, it will correct itself when the motor
cools (10-20 minutes). If this overheating problem persists, re-
place the blower motor
.
3
Excessive time is required to raise the shortening to
cooking temperature. Temperature recovery is slow
and main burner flames are small and appear to be
lethargic.
A. Ensure that the MANUAL GAS VALVE is completely open.
B. Check for an obstruction in the gas line.
C. Check for an obstruction in the flue pipe.
D. Check that the ORFICE PLUG has the correct drill size opening as
indicated on the operational requirements chart.
E. Check for damaged BLOWER fins.
F. Use a standard water-type U-gauge Manometoer to check the pres-
sure at the gas control valve pressure tap. Proper gas pressure is
indicated on the operational requirements chart.
NOTE: If necessary remove the Pressure Regulator Adjustment Cover
and adjust this control to the proper pressure. (Turn adjusting screw
CLOCK-WISE to increase gas pressure to the burner and COUNTER
CLOCKWISE to decrease gas pressure. Replace adjustment cover.)
4
Shortening temperature is too high and breaks down
quickly.
A. Check the gas pressure as described above.
B. Check calibration of the Electronic Thermostat with an
ACCURATE digital thermometer.
5
The filter pump motor fails to operate when the Vat
Shortening Return / Topside Shortening Lever is
placed in the
OPEN
position.
A. Insure the filter pump micro-switch is good, then check the manual
reset button on the filter pump motor.
B. If the filter pump motor fails to operate after the reset button has
been depressed, repair or replace the motor.
6 Decreased shortening flow rate while filtering.
A. Check for excessive sediment on the filter screen, standpipe suction
fitting or in filter tub.
7
Pump/Motor operates but does not pump shoreten-
ing. A. Check for congealed shortening in the shortening system.
B. Check for loose Standpipe / Suction Line Coupler connection.
8 Pump / Motor hums but will not pump shortening
A. Check for congealed shortening in the pump or in shortening
plumbing.
