Display shows HS; ice or water dispenser may not function correctly; humidity control features may be affected.

Safety first: Unplug the refrigerator before removing dispenser panels or working in the hinge area. Be careful not to damage water lines in the door.

Step 1 – Inspect dispenser area:

• Check for condensation or frost around the dispenser and door edges.
• Ensure the dispenser area is dry and free of spills that could affect sensors.

Step 2 – Check door harness at the hinge:

• Open the fresh food door and locate the wire harness at the top or bottom hinge.
• Inspect for pinched, broken, or frayed wires.
• Gently move the harness while observing the display; intermittent changes suggest a harness issue.

Step 3 – Access humidity sensor (if applicable):

• Remove the dispenser trim and control panel carefully (usually snaps or screws).
• Locate the humidity sensor or related board in the dispenser assembly.
• Check connections and look for corrosion or moisture damage.

Step 4 – Test and replace components:

• If the humidity sensor tests out of spec (per tech sheet) or shows visible damage, replace the humidity sensor or dispenser control module.
• If the mullion or door heater is open-circuit, replace the door heater assembly.

Step 5 – Control board evaluation:

• If wiring and sensors are good, the main control board may be misreading the humidity circuit.
• Replace the main control board if indicated by diagnostics.

When to call a technician: Door harness and dispenser repairs can be delicate. If you are unsure, seek professional service to avoid damaging the door assembly.
