Humidity Sensor disconnection or short circuit.

First step from the service manual

At home-bar Heater On/Off or Defrosting start condition, the starting condition by the Humidity Sensor is ignored. Automatically cancelled if Humidity-Sensor is normal.

What HS means on a Daewoo refrigerator

The HS error code on a Daewoo refrigerator indicates a fault with the humidity sensor, specifically either a disconnection (open circuit) or a short circuit condition. The humidity sensor is typically located in the home-bar section of the refrigerator and is used to regulate the home-bar heater cycling and defrost initiation. When the control board cannot receive a valid signal from this sensor, it logs the HS code to alert the technician or user that sensor input is unavailable.

When the HS code is active, the refrigerator's control logic enters a protective mode. Specifically, if a home-bar heater on/off cycle or a defrost start condition is triggered, the system ignores any input that would normally come from the humidity sensor. The refrigerator continues to operate, but humidity-based control decisions are bypassed until the sensor returns to a normal reading. If the sensor recovers on its own, such as after a loose connection is restored, the error is automatically cancelled without requiring a manual reset.

Common causes of this fault include a physically disconnected wiring harness at the sensor connector, corrosion or moisture damage to the connector pins, a failed sensor element that has developed an internal short or open, or damaged wiring between the sensor and the control board. Because the error can self-clear when the sensor returns to normal, intermittent connection problems are a frequent culprit and may require careful inspection of the harness routing and connector seating rather than immediate part replacement.

Common causes of HS

  1. 01

    Disconnected wiring harness

    Wiring / connection

    The connector linking the humidity sensor to the control board may have come loose due to vibration or handling. Check that the harness is fully seated at both the sensor and board ends.

  2. 02

    Corroded or damaged connector pins

    Wiring / connection

    Moisture exposure in the home-bar area can cause corrosion on the sensor connector pins, creating a high-resistance or open connection. Inspect the connector visually for oxidation, pitting, or bent pins.

  3. 03

    Failed humidity sensor

    Part replacement

    The sensor element itself may have developed an internal open or short circuit, causing the control board to read an invalid signal. A failed sensor will not self-correct and will require replacement.

  4. 04

    Damaged wiring between sensor and control board

    Part replacement

    The wire run from the humidity sensor to the main control board may be pinched, chafed, or broken, especially at points where it passes through cabinet panels or door hinges. Continuity testing along the full harness length can identify a break.

  5. 05

    Control board input fault

    Part replacement

    In less common cases, the sensor input circuit on the main control board may be damaged, causing it to misread a properly functioning sensor as disconnected or shorted. This is typically diagnosed after the sensor and wiring have been confirmed good.

Frequently asked questions about HS

What does HS mean on a Daewoo refrigerator?
The HS code indicates that the refrigerator's humidity sensor has been detected as either disconnected or short circuited. This sensor is part of the home-bar control system and helps manage heater cycling and defrost conditions. While the error is active, the control system bypasses humidity sensor input and continues operating. If the sensor signal returns to normal, the error clears automatically.
Can I fix the HS error myself?
In many cases, yes. Start by inspecting the humidity sensor connector for loose connections, corrosion, or damaged pins, as these are the most common causes. If the wiring and connector look intact, the sensor itself may need replacement, which is a straightforward swap for someone comfortable with basic appliance repair. If the wiring harness or control board is damaged, the repair becomes more complex.
Is the HS error dangerous, and can I keep using my refrigerator?
The HS error is not a safety hazard. The refrigerator continues to operate and cool normally while the error is active, with the control system simply ignoring humidity-based input for the home-bar heater and defrost functions. It is generally safe to keep using the unit, though having the sensor fault repaired promptly will restore full automatic control of the home-bar area.
Will resetting the refrigerator clear the HS error?
A manual reset alone is unlikely to permanently clear the HS code if the underlying sensor fault still exists. However, the error is designed to cancel automatically if the humidity sensor returns to a normal operating state on its own. If a loose connector is reseated and the sensor reads correctly, the code will clear without any reset needed. If the sensor or wiring is genuinely failed, the code will return after any reset.
How much does it cost to repair the HS error on a Daewoo refrigerator?
Repair costs vary depending on what is causing the fault. If only a connector needs reseating or cleaning, there may be no parts cost at all. A replacement humidity sensor typically runs in the range of $15 to $50 for the part. If a professional technician is needed, expect labor costs of $75 to $150 or more depending on your location and the complexity of the diagnosis.
