Verify that the auto top off power switch is
switched on. (removed in later models)
The switch is located behind the JIB on the
left side of the auto top off control box.
Check solenoid to see if functioning
properly.
If the solenoid is working, ensure that the
screws on the bottom of the pump are not
too tight. Loosen the screws. If loosening
the screws doesn’t fi x the problem, replace
the pump.
Ensure transformer in ATO box is
functioning properly. Check power from
transformer to ATO board. Ensure all
harnesses are plugged securely into place.
Check to see that fryer is heating. Fryer
temperature must be at least 300°F
(149°C). Check probe resistance. If probe
is bad, replace the probe.
Ensure oil viscosity is thin enough to pump.
Power to the ATO board has been cut off.
Restore power to the board and cycle all
computers off and on to readdress system.
Check for proper voltages using the pin
position chart found on pages 40-41 at
the back of this manual. If ATO found
defective, replace ATO board.
