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)
ORANGE
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.
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 on the chart
shown on page 7.
E. Check for damaged BLOWER fins.
F. Use a standard water-type U-gauge Manometoer to check the
pressure at the gas control valve pressure tap. Proper gas
pressure is indicated on the perational requirements chart
shown on page 6.
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 shore-
tening. A. Check for congealed shortening in the shortening system.
B. Check for loose Standpipe / Suction Line Coupler connection.
