POWER AND GAS MUST BE TURNED OFF PRIOR TO PERFORMING ANY MAINTENANCE OR REPAIR.
ITEM PROBLEMS
1 Main burner will not ignite. Blower is
operating; but gas is not present at the
burner.
2 Electrical power is present at the fryer
but the Blower is not operating.
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.
4 Shortening temperature is too high
and breaks down quickly.
5 The filter pump motor fails to operate
when the Vat Shortening Return /
Topside Shortening Lever is placed in
the OPEN position.
6 Decreased shortening flow rate while
filtering.
7 Pump/Motor operates but does not
pump shortenings.
8 Pump / Motor hums but will not pump
shortening
TROUBLESHOOTING CHART
POSSIBLE SOLUTIONS
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
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, replace the blower.
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 table
on page 6.
E. Check for BLOWER damage.
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 table on page 4a-4c.
NOTE: If necessary remove the Pressure Regulator Adjustment Cover and adjust
this control to the burner and COUNTER CLOCKWISE to decrease gas
pressure. Replace adjustment cover.)
A. Check the gas pressure as described above.
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.
A. Check for excessive sediment on the filter screen standpipe suction fitting or in filter tub.
A. Check for congealed shortening in the shortening system.
B. Check 11mm Bulkhead connection (STAUBLI).
A. Check for congealed shortening in the pump or in shortening plumbing.
