Whirlpool Refrigerator H — High Temperature Alarm

Whirlpool Refrigerator · Error code H

What H Means

'H' (sometimes 'HI' or accompanied by a temperature reading) is a high-temperature warning that the fresh food or freezer compartment exceeded the safe threshold (typically 48°F fresh food or 15°F freezer) for more than 90 minutes.

Symptoms

  • 'H' or 'HI' on display
  • Audible alarm tone
  • Food feels warmer than expected
  • Often appears after long door-open or power event

Common Causes

1
Door left open

Most common — door ajar overnight or after grocery loading.

2
Recent power outage

Often appears alongside or instead of PO.

3
Failed door gasket

Air leaking past a damaged seal.

4
Cooling problem developing

Compressor weakness or refrigerant loss starting.

How to Fix It

  1. Press any key to silence the alarm.
  2. Verify all doors are fully closed and gaskets are sealing (dollar bill test).
  3. Check food for thaw; do not refreeze meat/dairy that warmed past 40°F.
  4. Watch for 24 hours — if temperatures return to setpoint and H does not return, you are done.
  5. If H keeps reappearing, vacuum the condenser coil and check the condenser fan; if it persists, follow F3 E1/E2 thermistor steps.
