How to Fix SH Error (Step-by-Step)

Unplug the refrigerator from the wall outlet to ensure your safety.
Locate the faulty temperature sensor. It is typically inside the fresh food compartment, behind a small plastic cover along the top or back wall.
Remove any shelves that are in the way. Use a small flathead screwdriver to gently pry off the plastic sensor cover.
Disconnect the sensor by pressing the locking tab on the wire harness connector and pulling it apart.
Connect the new temperature sensor (Part #240597203) to the wire harness. You should hear a click as it locks into place.
Snap the plastic cover back over the new sensor and reinstall any shelves you removed.
Turn the appliance off, wait about 2 minutes, then turn it back on.

What to Check Next on This Frigidaire Refrigerator

Focused repair path: refrigerator door, airflow, sensor, defrost, dispenser, and control checks. Do not treat this as a reset-only problem if the code keeps returning; use what the appliance does during the failed part of the cycle to choose the next check.

Confirm the doors close fully, the gaskets seal, and the display is not reacting to a door left open or a blocked switch.
Check for blocked vents, heavy frost, stalled fans, warm compartments, or recent power interruptions before replacing electronic parts.
If the code involves temperature or airflow, inspect the evaporator fan, thermistor, defrost path, wiring, and control connections.
If the symptom follows a door or dispenser event, check the switch, harness, hinge wiring, and connector seating first.
Use the full Frigidaire refrigerator model number before buying parts because sensors, boards, fans, and switches are model-specific.

Check, inspect, clean, test, measure, remove, reconnect, clear, and replace parts only when the symptom supports that path. If these checks point toward a part, verify the complete Frigidaire model number from the appliance tag before ordering. The same error wording can use different valves, sensors, pumps, motors, heaters, locks, switches, or control boards depending on the exact model.

When It’s Better to Replace Than Repair

Refrigerator repairs can become costly when sealed-system, control, defrost, fan, or ice-maker issues repeat.
Confirm width, height, depth, door swing, counter-depth needs, water line, and delivery path before ordering.
