Machine Doesn’t Run
Assuming the selector switch is set to “ICE,” look for the following issues.
- Power supply problems – The machine might be off or unplugged. If neither is the problem, check if the power cord is damaged or if there is a field wiring deficiency. Faulty wiring should be repaired by a professional service technician.
- High pressure safety control tripped – If the safety control is tripped, you’ll need to reset it and see what’s causing high head pressure.
- High temperature safety control open – When the high temperature control is open, replace it and see what’s causing it to be open.
- Bin control out of alignment – See if the bin control needs to be adjusted or defective. If it’s faulty, replace it immediately.
- Liquid line solenoid energized and open – Find the reason why the liquid line solenoid is unopened or inactive, replace it.
Machine Not Making Ice
Here are some factors that could be preventing the machine from making ice.
- Compressor not running – There are a couple of reasons that keep the unit’s compressor from running. A bad contactor or coil might need to replaced, or it could be a broken compressor or starter components. Replace these parts or the entire compressor assembly.
- Water leaking – Look for leaking out of the purge drain or water trough. Both could will prevent the production of ice. If either shows signs of leaking, replace or repair them.
- Low suction pressure – Since this requires the handling of refrigerant, make sure it’s looked at and repaired by a certified technician.
- Dirty condenser – An unclean condenser can increase pressure head and effect air flow, lowering production of ice.
- Leaking hot gas valve – If the hot gas valve leaks during freezing, you’ll need to have the valve replaced.
Machine Not Harvesting
The harvest cycle starts when ice is ejected from its ice mold. When the machine doesn’t enter this mode, look for the following:
- Uneven freeze pattern on evaporator – An uneven freeze pattern can be linked to different factors. First, see if the compressor is worn out. If the compressor is in good shape, the issue could be tied to an overcharged system or a thermostatic expansion valve (TXV) that is stuck open.
- Leaking in valves – Check for leaks in either the purge valve or hot gas valve. Stop the leakage by replacing either valve or removing any obstructions.
- Timer issues – See if the timer initiate control needs to be readjusted or repaired. Also, check if the timer has a proper setting and operation. If not, it might be defective and need to be replaced.
- Open high temperature safety control – If this control is open, the manual purge switch won’t energize the purge valve into operation.
Machine Harvests Too Long
If the harvest cycle is excessive, check for these issues:
- Defective harvest assist assembly – If the harvest assist assembly is broken or not properly installed, replace or readjust it.
- Uneven ice formation on the evaporator – When the ice is uneven on the evaporator, there could be a refrigerant charge or leak. This MUST be handled by a certified technician.
- Defective hot gas valve – If the hot gas valve is broken or out of alignment, this could extend the harvest time. Readjust or fix immediately.
- Dirty evaporator – The evaporator is crucial during the freezing and harvest cycles. If it’s dirty, clean it to improve performance.
Hollow Ice Cubes
If you notice hollow ice cubes, look for these root causes:
- High water temperature – If the temperature exceeds 100°F, this will effect ice cubes during freezing and production. Correct the temperature in your facility.
- Water leaking – Check for leakage from the purge drain. A broken drain or blockage could be causing a leak.
- Timer issues – If the timer is set properly, see if the module needs to be readjusted or is broken. Also, check if the timer initiate control needs to be realigned or repaired.
