DIAGNOSTICS
Common Sub-Zero Issues We Fix in Katy
Ice Maker Not Producing Ice
Usually caused by a failed water inlet valve or ice maker module. We diagnose and replace the correct component — no unnecessary part swaps.
Water Leaking Under Refrigerator
A clogged drain line or worn door gasket is the most common cause. We clear blockages and replace gaskets with genuine Sub-Zero parts.
Error Codes EC 50 / EC 40
These codes point to evaporator fan failure or control board faults. Our technicians read Sub-Zero diagnostic data and repair the root cause.
High Temperature in Both Sections
Dirty condenser coils or a failing compressor cause this. We clean coils on every visit and evaluate compressor health with proper equipment.
Gurgling or Water Noise Behind Unit
Normal refrigerant flow can mimic problems. We distinguish normal operation from defrost cycle issues or refrigerant charge faults.
Frost Buildup in Freezer
A failing door gasket or defrost heater lets warm air in. We test both and replace whichever is at fault — backed by our 90-day warranty.
