Display shows H1, unit does not blow warm air immediately in heating mode

Note: H1 on many Electrolux heat pump models is an informational code, not a fault.

Steps:

• Wait for cycle: Allow 5–15 minutes for the defrost or preheat cycle to complete. The indoor fan may run slowly or stop to prevent cold drafts.
• Check outdoor unit: Ensure the outdoor coil is not heavily iced over. Light frost is normal; thick ice indicates a defrost or airflow issue.
• Clear obstructions: Remove snow, leaves, or debris blocking the outdoor coil.

If H1 remains for an unusually long time and heating is poor, a technician should check the defrost sensor and control logic.
