Refrigerator displays H2, often associated with freezer temperature issues.

Safety first: Unplug the unit before removing any panels.

• Door and gasket check: Confirm the freezer door closes fully and the gasket is not torn or warped.
• Look for frost patterns: Remove the freezer rear panel and inspect the evaporator coil. A solid block of ice suggests defrost failure; a partial frost pattern may indicate sealed system issues.
• Test freezer thermistor: Measure resistance and compare to Electrolux specs. Replace if out of range.
• Monitor compressor run time: If the compressor runs constantly and cannot reach set temperature, a sealed system problem may exist. This requires a certified technician.
