(continued)
Error Code Description/Action Probable Cause Remedy
CYL RFG. This error occurs when
cylinder system run time
exceeds 90 minutes.
Cylinder switches to
STBY mode and locks
out.
Action: Cylinder
Refrigeration off, cabinet
refrigeration continues
to operate.

rectified.
10. Water Flow
Restriction (Water
Cooled Only)
11. AXV not set
properly/not responding
12. Compressor Failure/
Reduced Capacity
13. Moisture in system
14. Compressor Control
Relay not activating
10. Locate and remove restriction, re-
start system to check for further issues
11. Check System refrigerant level,
attempt to re-set AXV valve pressure.
If valve is not responsive, it may need
to be replaced
12. Check Voltage to the unit to
ensure it is within specification,
Check wire connections to the unit
and compressor, Check compressor
contactor for loose wire connections
and proper operation, and possible
voltage drop, ohm compressor
windings to check for a short and
proper winding resistance, check
compressor starting components for
failure, allow compressor protector to
reset and check for proper amp draw.
13. Recover refrigerant, change
filter drier, change compressor oil
(Contact H.C. Duke & Son for proper
compressor oil charge), Evacuate
system to a minimum of 200 microns
or less. Repeat if necessary
14. Check to see if Relay is receiving

and repair.
3. Check door gasket for wear, check
evaporator fan motor for proper
operation, check spring loaded door
closer for proper operation.
4. Ensure the Cabinet TXV Superheat
is at 10 to 12 degrees once the
system is close to set point. Adjust if
necessary
