ELECTRO FREEZE Soft Serve Model GEN-5099
14 VQM Error Codes
Error Code Description/Action
CYL Rfg. This error occurs when
barrel system run time
exceeds 90 minutes.
Barrel switches to night
mode and locks out.
Action: Barrel
Refrigeration off, hopper
refrigeration continues
to operate.

(continued)
Probable Cause
1. Dirty Condenser
2. Shortage of
Refrigerant
3. Faulty wire
connection
4. Solenoid valve not
activating
5. Compressor starting
components failure (1
Phase Only)
6. Compressor
Contactor Failure
7. Compressor
Contactor Control Relay
not activating
8. System lacks
efficiency
9.Faulty Thermistor
Remedy
1. Clean Condenser
2. Locate Source of refrigerant leak
and repair.
3. Locate faulty connection (Wire
rubbed through, cut) and repair as
needed.
4. Determine if Solenoid coil is
receiving proper voltage (208/230
Volts), If coil is receiving voltage,
ohm out coil windings. If coil is
not receiving voltage, check relay
responsible for activating coil and
repair as needed. If this condition
exists a LOW PSI error code may also
trip.
5. Check Compressor Starting
components and replace as
needed.
6. Check contactor coil for proper
resistance, check for voltage drop
across contact points. Replace as
needed
7. Check to see if Relay is receiving
power from Main P.C. board (12VDC),
Ohm relay control coil for proper
resistance. Replace relay as needed.
If no 12VDC is detected Contact
Electro Freeze Factory Tech Support.
8. Check for worn blades, AXV
pressure settings, Check water
regulating valve setting (Water
Cooled), check refrigerant level,
compressor efficiency.
9. Remove thermistor, check in ice
water and compare to thermistor curve
chart. If faulty replace, if thermistor
tests o.k. check wire harness
connections. If all connections are
sound possibility of control board
issue. (Contact Electro Freeze for
proper compressor oil charge)
