How to Fix E1 Error (Step-by-Step)

Unplug the refrigerator from the power outlet for safety and confirm the error stays cleared during a full test cycle.
Empty the fresh food section to get clear access to the interior walls and ceiling.
Locate the thermistor cover. It’s a small, vented plastic housing, usually on the upper right side wall or near the control housing at the top.
Use a small flathead screwdriver to gently pry the cover off, exposing the sensor probe.
Disconnect the wire harness attached to the old thermistor. It will have a small clip you need to press.
Connect the new thermistor to the wire harness until it clicks into place.
Snap the plastic cover back on, return food to the refrigerator, and plug the unit back in.
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.
