GE Refrigerator Error Code HH

HH means the control and display sensor has detected a temperature above 99°F inside the refrigerator, which is considered abnormally high. GE designs the control board to trigger this code along with an alarm to warn you that safe food storage temperatures are not being maintained. The alarm will clear on its own once the temperature drops back to 97°F. You can press SET to silence the audible alarm while the unit recovers.

Yes, temperatures above 99°F inside a refrigerator mean food is well outside the safe storage range of 40°F or below. Perishable items like dairy, meat, and leftovers can become unsafe quickly at such temperatures. If the unit does not recover to normal cooling within a short time, move perishables to another refrigerator or cooler and diagnose the cooling problem before restoring food storage.

Unplugging the unit may temporarily clear the error from the display, but the code will return if the underlying temperature problem or sensor fault has not been resolved. The correct way to clear HH is to allow the refrigerator compartment to cool back down to 97°F, at which point the alarm disappears automatically. A power reset alone is not a fix if the unit is genuinely not cooling.

Pressing SET only dismisses the audible alarm. It does not fix the underlying temperature problem. The HH code will remain on the display until the compartment temperature actually drops to 97°F or below. If the temperature does not recover, you need to diagnose why the unit is not cooling properly.

Repair costs depend on the root cause. Cleaning condenser coils is a no-cost DIY task. Replacing a temperature sensor typically runs in the range of $20 to $75 for the part. An evaporator fan motor replacement can cost between $40 and $150 in parts, with additional labor if a technician is hired. Defrost system component repairs vary widely depending on which part has failed.
