A. Ensure JIB has oil.

 

 

 

 

 

B. Check to

see that fryer is heating.

 

 

 

 

Fryer temperature must be at setpoint.

 

 

 

 

Check probe resistance. If probe is

 

 

 

 

bad, replace the probe.

 

 

 

A. Empty JIB.

C. Ensure that the oil in the JIB is above

 

 

 

 

70°F (21°C).

 

 

 

 

B. Probe temperature lower than setpoint.

D. With the computer OFF, press TEMP

Ensure all harnesses are plugged

 

I.

ATO lines/pump plugged

 

securely into place.

 

 

 

G. Ensure pump

is operational.

Check

 

 

 

 

voltage to pump. Replace the pump if

 

 

 

 

defective.

 

 

 

 

 

 

 

H. Check for proper voltages using the pin

 

 

 

 

position chart found on page 1-15. If

 

 

 

 

ATO found defective, replace ATO

last display.

 

 

 

 

 

 

 

 

 

 

 

 

 

B. Check actuator, ATO pump, wire

 

 

 

 

connections, RTD and ATO board.

 

 

 

A. Ensure fuse on right side of ATO box is

 

 

 

 

secure and good. If the computer

 

 

 

 

above the ATO box is missing power

 

 

 

 

check the fuse below the component

 

 

 

 

box.

 

 

 

 

 

 

 

 

B. With the computer OFF, press TEMP

C. ATO Board power loss

 

may be bad.

Ensure the 6-pin CAN

 

 

 

 

connectors are tight between AIF (J4

 

 

 

 

and J5) and ATO (J9 or J10) boards.

 

 

 

C. Power to the ATO board has been cut
