Kenmore Air Conditioner Error Code HS

The HS code on a Kenmore air conditioner means the heat sensor has failed. The heat sensor monitors temperature within the unit, and when the control board detects a signal that falls outside the expected range, it triggers this error. The unit may limit or stop operation until the issue is resolved. Kenmore recommends calling 1-800-4-MY-HOME for professional repair.

Continuing to operate the unit with an active HS code is not recommended. The heat sensor is part of the temperature monitoring system, and running the unit without a functioning sensor means it cannot properly detect unsafe heat conditions. This could potentially lead to overheating or component damage over time.

Kenmore specifically directs users to contact 1-800-4-MY-HOME for this error, indicating that a qualified service technician should handle the diagnosis and repair. The repair involves working with sensor wiring and potentially the control board, which requires proper tools and technical knowledge. Attempting self-repair without the appropriate background risks further damage to the unit.

A power reset may temporarily clear the HS code, but if the heat sensor or its wiring has actually failed, the error will return once the unit restarts and polls the sensor again. Resetting does not repair the underlying hardware fault. A proper repair requires diagnosing and replacing the faulty component.

Repair costs vary depending on the root cause. If only a wiring connection needs to be reseated, the cost may be limited to a service call fee, typically in the range of $75 to $150. If the heat sensor thermistor needs replacement, parts and labor combined often fall between $100 and $250. A control board replacement would be at the higher end of the cost range.
