Haier Refrigerator Error Code HH

HH is a high temperature alarm code indicating the control and display sensor has detected an internal temperature above 99°F. This means the refrigerator compartment is too warm to safely store food. The alarm will clear automatically once the temperature drops to 97°F, or you can press the SET button to dismiss the display. Addressing the cause of the temperature rise is necessary to prevent the code from returning.

Pressing the SET button will dismiss the HH alarm on the display, and the display will also return to normal on its own once the compartment temperature drops back to 97°F. However, resetting or dismissing the alarm does not fix the underlying cause. If the cooling problem is not corrected, the compartment will warm up again and the HH code will reappear.

Repair costs vary widely depending on the cause. Simple fixes like cleaning condenser coils or replacing a door gasket typically cost between $20 and $100 in parts and minimal labor. A temperature sensor replacement generally falls in the $50 to $150 range including parts and labor. Compressor replacement or sealed system refrigerant repair is more involved and can range from $200 to $600 or more depending on parts availability and labor rates in your area.

Start by checking that the refrigerator door is fully closed and that the door gasket is sealing properly all the way around. Make sure the condenser coils are not clogged with dust and that there is adequate clearance around the unit for airflow. If those checks do not resolve the problem, the issue may involve the evaporator coils, compressor, refrigerant level, or the temperature sensor itself, which may require a technician to diagnose.

Yes, temperatures above 99°F inside a refrigerator represent a serious food safety risk. Perishable foods like meat, dairy, and leftovers should not be held above 40°F for extended periods. If the HH alarm has been active for more than a couple of hours, inspect food carefully and discard anything that may have been in the temperature danger zone for too long.
