Maytag Refrigerator Error Code HRS — Refrigerator Sensor Out of Range (High)
What this means
The HRS error on Maytag refrigerators indicates the refrigerator compartment temperature sensor (thermistor) is reading a temperature above the expected range. This can be caused by a faulty thermistor, a loose wire connection, or an actual high-temperature condition caused by a cooling system problem such as a failed evaporator fan, blocked vents, or a compressor issue.
Step-by-step fix
4 stepsCheck for obvious cooling problems
Open the refrigerator and check if the air feels warm. Check the freezer — is it cold? If the freezer is cold but the fridge is warm, the evaporator fan may not be circulating air, or the damper may be stuck closed.
Place a thermometer in both compartments and check again after 30 minutes for accurate readings.
Inspect the air vents between freezer and fridge
Check the vents that allow cold air from the freezer to flow into the refrigerator compartment. Ensure they are not blocked by food items.
Do not overpack the refrigerator — cold air needs to circulate freely.
Test the thermistor
Disconnect power. Locate the refrigerator compartment thermistor (usually clipped to the air duct or mounted on the back wall). Disconnect it and test resistance. At room temperature, it typically reads around 10,000–15,000 ohms depending on the model.
Compare your reading to the temperature-resistance chart in your model's tech sheet for accuracy.
Replace the thermistor if out of range
If the thermistor resistance does not match the expected value for the current temperature, replace it. Clip the new sensor into place and reconnect the wiring.
If the thermistor is fine but the temperature is genuinely high, investigate the cooling system — evaporator fan, damper, and compressor operation.
When to call a professional
If the thermistor is accurate and the temperature is genuinely high, the cooling system has a problem (sealed system leak, failed compressor, etc.) that requires professional repair.
