Start with the ice maker setting and freezer
First confirm that the ice maker is switched on and that a full bin or raised shutoff arm is not telling it to stop. Controls vary by model, so check the owner manual before changing settings. If the freezer is running warm, ice production can slow or stop even when the ice maker itself is working.
Use a thermometer to compare the actual freezer temperature with the setting. Note whether food is softening or frost is building up; those clues may point to a freezer cooling problem rather than an ice-maker fault.
Look for a water-flow problem
A clogged refrigerator filter, a closed supply valve or a kinked water line can keep the ice maker from filling. If the water dispenser is also slow, that is useful information. Do not force a frozen fill tube or dismantle the water valve without model-specific instructions.
Small or hollow cubes often suggest an incomplete fill, while cubes trapped in the mold suggest a different issue. Reporting the exact pattern helps a technician focus the diagnosis.
When service is the right next step
If the freezer temperature and visible water supply appear normal but ice production does not return, the fill valve, sensors, wiring or ice-maker assembly may need testing. Replacing the assembly before checking water flow can leave the original problem unresolved.
When you contact Nova, send the refrigerator model number, note whether the dispenser works, and describe whether there is no ice, slow ice, leaking or overfilling. We service refrigerator and built-in ice makers across the Austin metro.
