How do I clean the ice thickness probe on my Manitowoc?

Follow the cleaning procedure in the manual, which covers removing and cleaning the probe with an approved solution. Turn the machine off first and handle the probe gently, since bending it changes the cube thickness. If cubes are still wrong afterward, the probe gap or the control may need checking.

Our Mint Hill well water seems to clog the fridge filter quickly. Does that hurt the ice maker?

A clogged filter reduces flow, which leads to small cubes or none at all, and sediment can wear the inlet valve. Change the filter more often if needed, and consider a sediment filter for the house. We can check the valve if production stays low.

The water line to our fridge in an older Matthews home looks brittle. Should it be replaced?

If the line is thin plastic or the saddle valve is old, replacing it is a sensible precaution against leaks. We can connect a new line at the refrigerator. A failing shutoff valve in the wall may need a plumber.

Manitowoc Ice Makers: What We Check First

A Manitowoc cube machine runs a cycle that depends on two small probes. The ice thickness probe sits near the evaporator face and signals the control when the ice slab has grown thick enough for water to bridge to it. The water level probe sits in the trough and tells the inlet valve when to stop filling. Between them, they decide how full the evaporator gets and when harvest starts. The water pump and distribution tube keep water flowing evenly over the nickel-plated evaporator.

Scaled ice thickness probe triggering harvest early, making thin cubes
Fouled water level probe causing short or overflowing trough fills
Clogged distribution tube leaving dry streaks on the evaporator
Recirculating condenser air lengthening freeze cycles in tight installations

The full explanation, including what you can safely check yourself and when repair beats replacement, is in our Manitowoc ice maker repair guide.

Water Supply Problems Come First

An ice maker needs steady water pressure and a clear path from the shutoff valve to the fill tube. In older homes, the saddle valve or thin plastic line feeding the refrigerator may be decades old, and it can clog, crack or barely open. Homes on private wells can push sediment into the refrigerator filter and inlet valve, and low well pressure produces small or hollow cubes.

A garage refrigerator with an ice maker can also freeze its supply line on the rare hard-freeze nights, while summer heat in the same spot slows production. Garage units also tend to collect dust on their condenser coils, which reduces freezer temperature and slows ice harvests. Cleaning the coils with the unit unplugged is a worthwhile first step.

Checks You Can Make and What We Do

Make sure the ice maker is switched on and the bin is seated. Replace an overdue water filter, and check behind the fridge for a kinked or leaking line. Turn the water off if you see a leak. The technician tests the inlet valve, ice maker module, fill tube and freezer temperature, and explains the repair and price before starting.
