1-3. TROUBLESHOOTING
(Continued)
Problem
Slow to decrease
in temperature (decline in
performance)
Display temperature does
not match the actual inlet air
temperature (No alarm)
Green compressor indicator
light on and the compressor
not working, or working
sometimes
603
Cause
Condenser obstructed by dirt
Evaporator iced up
Refrigerating problem
In Frigiprobe Mode, the display
shows the product temperature
In timer mode, or hold mode,
the probe may be showing the
wrong temperature
Compressor and condenser fan
do not work:
- Faulty contactor
- Faulty control board relay-no
voltage across terminals 10-11
Compressor works, but condenser
fan does not:
- Faulty condenser fan
Compressor and condenser fan
work together:
- Faulty protection component
for the compressor (overload
protector, potential relay, start
and run capacitor)
- Faulty overload protector of
condenser fan
Model BCF-24/65/110, BCM-110
Correction
Clean the condenser
Perform a De-icing Cycle
Check refrigeration circuit and
components
Normal
Ohm out the probe and check
the reading with the table located
in this section; change the probe
if it is out of tolerance
Check contactor and change if
necessary
Replace control board
Replace fan
Check items and replace if
necessary
Check fan and replace if
