Possible Causes

Freezer door left open, Failed freezer thermistor, Defrost failure causing frost blockage, Sealed system cooling issue

Safety: Basic checks can be done without tools.

Check door and gasket: Ensure the freezer door closes fully and the gasket is intact.
Inspect for frost: Look at the back freezer wall; heavy frost indicates a defrost problem.
Monitor temperature: Place a thermometer in the freezer and check after 12–24 hours.

If the freezer remains warm or the H2 code persists, the freezer thermistor, defrost system, or sealed system should be tested by a technician.
