Frypot temperature is more than 21ºF
(12ºC) below setpoint.
This display is normal when the
fryer is first turned on and may
appear for a short while if a large
batch of frozen product is added to
the frypot. If the display never
goes out, the fryer is not heating.
Look for a decimal in the LED
display between digits 1 and 2. If
the decimal is present, the
computer is calling for heat and is
functioning properly. See Fryer
Does Not Heat in Control and
Heating Problems (Section 6.2.1).
If the decimal is not present, the
computer is not calling for heat and
may be malfunctioning. If
available, substitute a controller
known to be working for the
suspect computer. If the fryer
functions correctly with the
substitute computer, order a
replacement computer from your
FASC.
