Why Your Follett Ice Machine Stopped Making Ice
A Follett ice machine will stop producing ice if the machine cannot get enough clean water, cannot remove heat efficiently, or receives a signal that interrupts production. Start with basic checks, such as power, water supply, filters, drains, and airflow.
Water Supply Problems
Water supply issues can prevent a Follett ice machine from producing ice properly. Common causes include:
- Low Water Pressure: Confirm the facility's water supply meets the requirements listed in the model's manual.
- Clogged Filter: Replace dirty or expired water filters.
- Closed Valve: Confirm the water supply valve is fully open.
- Kinked Water Line: Inspect the supply line for bends, pinches, or compression.
- Frozen Line: Thaw frozen sections and address temperature issues.
- Mineral Buildup: Clean and descale components regularly.
Scale Buildup Inside the Machine
Scale buildup inside a Follett ice machine can restrict water flow and reduce freezing performance. Common causes include:
- Hard Water Minerals: Mineral deposits can accumulate inside evaporators and water lines over time.
- Restricted Water Flow: Scale buildup may partially block internal water pathways and reduce ice production.
- Reduced Freezing Efficiency: Heavy buildup can interfere with proper heat transfer during ice formation.
- Dirty Internal Components: Scale and debris may collect on critical components and impact performance.
When cleaning a Follett ice machine, use only the cleaner or descaler recommended for the specific model.
Dirty Condenser Coils
Dirty condenser coils can restrict airflow and cause a Follett ice machine to stop making ice. Common causes include:
- Dust Buildup: Dust accumulation may block airflow and reduce cooling efficiency.
- Grease Buildup: The airborne grease common in commercial kitchens can coat condenser coils and trap heat.
- Restricted Ventilation: Limited airflow around the machine may increase operating temperatures.
- Overheating Components: Dirty coils can force the refrigeration system to work harder during ice production.
- Infrequent Cleaning: Condenser coils that aren't cleaned regularly may reduce ice output over time.
Before cleaning, disconnect power and follow the model's manual. Use a soft brush, vacuum, or approved condenser cleaning method. Avoid bending coil fins.
Bin Sensor or Control Board Issues
According to Follet Technical Solutions Specialist Dan Glimn, "Follett machines use an infrared sensor to determine when the bin is full. If scale or slime builds up on that sensor, it 'blinds' the machine, causing it to stop making ice even if the bin is empty." Sensor or control board problems may interrupt normal ice production cycles. Common causes include:
- Dirty Bin Sensors: Ice buildup or debris may prevent sensors from reading ice levels correctly.
- Faulty Sensors: Damaged sensors may incorrectly signal the ice bin is full.
- Power Interruptions: Sudden power loss may temporarily disrupt machine controls.
- Control Board Malfunctions: Electrical or programming issues can interrupt freeze cycles.
- Loose Wiring Connections: Damaged or loose wiring may prevent components from communicating properly.
Clean sensors according to the manual before replacing parts. If indicator lights, error codes, or shutdowns return after cleaning and resetting the unit, call a technician.
Refrigeration or Auger System Problems
If your Follett ice machine is running but not making ice, refrigeration or auger system issues may be preventing proper ice production. Common causes include:
- Compressor Failure: A damaged compressor may prevent the evaporator from reaching freezing temperatures.
- Low Refrigerant Levels: Refrigerant leaks can reduce cooling performance and interrupt ice production.
- Auger Motor Problems: Worn or damaged auger motors may stop ice movement through the machine.
- Freeze Cycle Issues: Interrupted or inconsistent freeze cycles may prevent ice from forming correctly.
- Evaporator Problems: Damaged evaporator components can reduce freezing efficiency.
Follett Ice Machine Cleaning & Maintenance for Ice Production
Routine preventive maintenance helps prevent many Follett ice production issues. Regular cleaning, descaling, filter replacement, condenser care, and professional inspection help keep the machine producing ice consistently and reduce the chance of unexpected downtime.
Clean the Machine Regularly
Regular cleaning every six months, or more often in high-use or hard-water environments, helps remove scale and debris that can reduce ice production and affect performance. Following a consistent cleaning schedule helps maintain efficiency and extend equipment life. According to Glimn, "Neglecting the six-month cleaning cycle is like never changing the oil in your car. Eventually, the scale buildup creates enough friction that the motor simply burns out."
- Cleaning Tip: Always use manufacturer-approved cleaners and fully rinse the system after cleaning to prevent residue from affecting ice quality.
Replace Water Filters
Water filters help protect ice quality and machine performance by reducing sediment, taste, odor, and scale-forming minerals before they reach the machine. A restricted filter can lower water flow enough to reduce ice production or stop production entirely. Glimn states it's important to, "Always purge new water filters before connecting them; otherwise, carbon dust gets into the valve and creates black specks in your ice."
- Water Quality Tip: Hard water, sediment, or heavy usage may require more frequent replacement.
Keep Condenser Coils Free of Dust and Grease
Clean condenser coils help the machine release heat, maintain proper operating temperatures, and support steady ice production. Dust, grease, and restricted airflow can force the refrigeration system to work harder, especially in warm kitchens or enclosed spaces.
"An ice machine needs to breathe," Glimn told KaTom. "If you put it in a hot closet or block the air intake with other equipment, the ice production will drop significantly."
- Cleaning Tip: Inspect condenser coils regularly and clean them when dust, grease, or debris begins to accumulate. If the condenser is heavily coated in grease or difficult to access, schedule a professional cleaning.

FAQs About Follett Ice Machines Not Making Ice
What are common problems with Follett ice machines?
Common Follett ice machine problems include no ice production, slow ice production, unusual noises, clogged drains, water supply issues, dirty components, and error-related shutdowns. Follett manuals note some models monitor issues like high pressure, auger gearmotor amperage, clogged drains, and low water conditions, all of which can affect ice production.
Why is my Follett ice machine making noise but no ice?
A Follett ice machine that makes noise but not ice may have a water supply issue, clogged drain, dirty condenser, auger or gearmotor problem, or an internal error stopping production. If the unit is running but not producing ice, check for blocked airflow, a full bin sensor issue, water restrictions, and any service lights before calling a technician.
How do you reset a Follett ice maker?
To reset a Follett ice maker, check the error first, then use the reset process listed in your model's manual. On some Follett machines, hard errors will not clear by turning the power off and on; the reset button on the control board must be pressed. Follett also recommends consulting the troubleshooting guide or a service technician when an error occurs.
How often should a Follett ice machine be cleaned?
A Follett ice machine should typically be cleaned and sanitized at least semi-annually, with some parts cleaned more often depending on the model. Follett cleaning guidance lists weekly drain line and drain pan cleaning, monthly condenser cleaning for air-cooled machines, and semi-annual ice machine cleaning.
Why is my Follett ice machine making small, soft, or poor-quality ice?
Small, soft, wet, or poor-quality ice usually points to a cleaning, water flow, water quality, temperature, or mechanical issue. Start by checking the water filter, water supply, drain, condenser, and cleaning schedule. If maintenance doesn't improve ice quality, the evaporator, auger, refrigeration system, or sensors may need professional service.
Is it worth fixing a Follett ice machine or buying a new one?
It is usually worth fixing a Follett ice machine if the problem is minor, but replacement may make more sense if the machine is older, undersized, or needs a major repair.
