Monogram Refrigerator HRS Error: High refrigerator temp alarm
The HRS (High Refrigerator Set) code indicates the refrigerator compartment temperature sensor has detected a temperature significantly above the set point for an extended period, signaling a cooling failure in the fresh food section.

Answer to continue safely
Is it safe to keep using?
No. An HRS code means the refrigerator compartment has exceeded safe food storage temperatures. Perishables should be moved to a cooler or alternative refrigerator immediately.
Can I reset the code?
No. The HRS alarm will clear once the compartment temperature returns to within range of the set point. Simply resetting the code without fixing the underlying cooling problem means the alarm will return within hours.
When to stop immediately?
Stop if you notice: Refrigerator interior temperature is above 40°F — discard perishables held above this temperature for more than 4 hours., The compressor has been running continuously for more than 4 hours without cooling — this risks compressor damage..
Symptoms You May Notice
Fresh food compartment warmer than set point
Food in the refrigerator section feels warm or is spoiling prematurely; a thermometer placed inside reads above 40°F.
HRS displayed on the control panel
The Monogram display shows HRS or H alternating with temperature readings, accompanied by an audible alarm.
Compressor running continuously
The compressor runs without cycling off because it cannot bring the compartment to the set temperature, resulting in elevated energy use and heat output at the rear of the unit.
Freezer compartment unaffected
The freezer section may be maintaining normal temperatures while only the fresh food section is warm, indicating a damper or airflow issue rather than a total cooling failure.
Possible Causes
Air damper (diffuser) stuck closed
The motorized air damper that controls cold air flow from the freezer into the refrigerator compartment has failed in the closed position, starving the fresh food section of cooling.
Requires ProfessionalEvaporator fan motor failure
The evaporator fan that circulates cold air from the evaporator coil through both compartments has stopped, resulting in inadequate air circulation to the fresh food section.
Requires ProfessionalFrozen evaporator (see FF code)
A fully iced evaporator blocks airflow entirely, triggering the HRS alarm as temperatures rise in the fresh food compartment.
DIY PossibleRefrigerant leak or low charge
A loss of refrigerant reduces the system's cooling capacity, causing the fresh food compartment to warm while the compressor runs continuously.
Requires ProfessionalSafe Checks You Can Do
-
1
Verify set temperature and door seals
Confirm the refrigerator set point is 37°F (3°C) or below. Check that both doors seal properly using the paper test. Ensure vents inside the compartment are not blocked by food containers.
Overpacking the refrigerator blocks internal air circulation and can cause warm spots that trigger the HRS alarm.
-
2
Listen for evaporator fan operation
Open the refrigerator door and listen for the sound of the evaporator fan running (a consistent hum from the back wall of the freezer). If you hear no fan, press and hold the door switch to simulate a closed door and listen again.
The fan should run when the door switch is depressed (door-closed position). No sound indicates a fan motor fault.

3
Check for evaporator icing (FF condition)
Remove the evaporator cover panel at the rear wall of the freezer. If heavy frost is visible completely covering the evaporator coil, a defrost failure (FF) is causing the HRS alarm. Perform a 24-hour manual defrost.
If the coil is heavily iced, address the FF/defrost issue first — resolving that will likely clear the HRS code as well.
Tools required
When to Call a Professional
Contact a qualified technician if:
- The evaporator fan is running and the evaporator is clear of ice, but the fresh food section is still warm — the air damper or refrigerant system requires professional diagnosis.
- A refrigerant leak is suspected (hissing sounds, oil residue near refrigerant lines) — only EPA 608-certified technicians can handle refrigerant.
