How to Fix Frigidaire Refrigerator Error LO
Error Code: LO Difficulty: Easy

Problem: Low Temperature Alarm

How to Fix LO Error (Step-by-Step)
1. First, confirm that both the refrigerator and freezer doors are completely shut. Check for any items inside that might be preventing a tight seal.
2. Inspect the rubber door gaskets for any tears, dirt, or debris. Clean the gaskets with warm, soapy water and a cloth to ensure they seal properly.
3. Check the air vents inside both the freezer and fresh food compartments. Make sure they are not blocked by food packages, as this restricts cold air circulation.
4. If you have recently loaded a large amount of warm groceries or experienced a power outage, the alarm may sound until the unit cools back down. Allow 4-6 hours for the temperature to stabilize.
5. If the alarm continues after these checks, the temperature sensor (thermistor) may have failed. Unplug the unit, locate the sensor inside the fresh food section (usually a small plastic dome on the wall or ceiling), and replace it.
6. After trying all steps, press the ‘Alarm Reset’ or ‘OK’ button on the control panel to silence the alarm and clear the code.
7. Turn the appliance off, wait about 2 minutes, then turn it back on.

How to Fix Frigidaire Refrigerator Error OP
Error Code: OP Difficulty: Moderate

Problem: Open Sensor (e.g., Temperature Sensor)

How to Fix OP Error (Step-by-Step)
1. Unplug the refrigerator from the wall outlet to ensure your safety.
2. Locate the faulty temperature sensor. It is typically inside the fresh food compartment, behind a small plastic cover along the top or back wall.
3. Remove any shelves that are in the way. Use a small flathead screwdriver to gently pry off the plastic sensor cover.
4. Disconnect the sensor by pressing the locking tab on the wire harness connector and pulling it apart.
5. Connect the new temperature sensor (Part #240597203) to the wire harness. You should hear a click as it locks into place.
6. Snap the plastic cover back over the new sensor and reinstall any shelves you removed.
7. 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.
1. Confirm the doors close fully, the gaskets seal, and the display is not reacting to a door left open or a blocked switch.
2. Check for blocked vents, heavy frost, stalled fans, warm compartments, or recent power interruptions before replacing electronic parts.
3. If the code involves temperature or airflow, inspect the evaporator fan, thermistor, defrost path, wiring, and control connections.
4. If the symptom follows a door or dispenser event, check the switch, harness, hinge wiring, and connector seating first.
5. 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.

Problem: Defrost Heater Failure

How to Fix ER DH Error (Step-by-Step)
1. Disconnect the refrigerator from its power source and confirm the error stays cleared during a full test cycle.
2. Empty all contents from the freezer section and remove any shelves.
3. Remove the screws holding the interior back panel of the freezer. You may need to gently pry the panel off if it is frozen in place.
4. Use a hairdryer on a low heat setting to carefully melt any ice buildup covering the silver evaporator coils. Do not use sharp objects to chip away ice.
5. Locate the defrost heater, which is a glass or metal tube attached to the bottom of the evaporator coils.
6. Disconnect the wire harness attached to the heater. Unclip the old heater from the coils.
7. Clip the new defrost heater into the same position and reconnect its wire harness. Reassemble the freezer panel, shelves, and restore power.
8. 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.
1. Confirm the doors close fully, the gaskets seal, and the display is not reacting to a door left open or a blocked switch.
2. Check for blocked vents, heavy frost, stalled fans, warm compartments, or recent power interruptions before replacing electronic parts.
3. If the code involves temperature or airflow, inspect the evaporator fan, thermistor, defrost path, wiring, and control connections.
4. If the symptom follows a door or dispenser event, check the switch, harness, hinge wiring, and connector seating first.
5. 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.
