Problem Probable Causes Corrective Action
Frypots won’t top
off.
A. Auto top off power switch is off.
B. Probe temperature lower than
setpoint.
C. Oil viscosity too thick
D. ATO board power loss
E. Failed solenoid.
F. ATO pump failed or over
tightened.
G. Failed transformer/harness.
H. Failed ATO board.
A. Verify that the auto top off
power switch is switched on.
The switch is located behind the
JIB on the left side of the auto
top off control box.
B. 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.
C. Ensure oil viscosity is thin
enough to pump.
D. Power to the ATO board has
been cut off. Restore power to
the board and cycle all
computers off and on to
readdress system.
E. Check solenoid to see if
functioning properly.
F. 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 fix
the problem, replace the pump.
G. Ensure transformer in ATO box
is functioning properly. Check
power from transformer to ATO
board. Ensure all harnesses are
plugged securely into place.
H. Check for proper voltages using
the pin position chart found on
page 4. If ATO found
defective, replace ATO board.
