For persistent Er CE codes, testing circuits helps isolate whether the ice maker or main control board needs replacement.
With basic tools and safety precautions, this is a DIY fix. Follow some simple troubleshooting steps to get your ice maker working and banish the annoying Er CE from your fridge display.
Causes of the Er CE Error
The Er CE error code on Frigidaire refrigerators indicates a communication error between the ice maker board and the main control board. This error prevents ice production and dispenser operation. Below are the main causes leading to the Er CE error:
1. Loose, damaged, or corroded wiring
The wiring that connects the ice maker board to the main control board allows data transfer between the boards. If this wiring is loose, damaged, or corroded, communication errors like Er CE can occur:
- Vibration during shipping or installation may loosen connectors
- Rodents chewing on wires is a common cause of damage
- Humid environments can corrode copper wiring over time
Inspecting wiring and reseating connections often resolves Er CE errors. For damaged wires, the harness must be replaced.
2. Malfunctioning dispenser board or main control board
If wiring checks out okay, a malfunctioning control board is often the culprit behind Er CE errors:
- Faulty components on the dispenser board can disrupt communication
- Issues on the main control board prevent ice maker data transfer
- Power surges may corrupt memory or firmware causing errors
Replacing the suspect control board is the solution if wiring is undamaged.
3. Power surges, repeated power fluctuations, or electrical problems
Electrical issues like power surges, brownouts, and wiring problems can also lead to communication errors:
- Power surges from storms or faulty wiring can damage boards
- Repeated power fluctuations disrupt communication
- Loose neutral connections, unstable voltage, wrong outlet polarity are problems
Using a surge protector, checking outlet wiring, and inspecting the appliance power cord help avoid electrical issues.
Safety Tips
Servicing any appliance comes with electrical, mechanical, and injury hazards. It’s crucial to make safety your top priority by following some key guidelines. Taking the proper precautions will allow you to diagnose and repair issues like the Er CE error code safely.
1. Power off and unplug the appliance or switch off the circuit breaker before maintenance
The first step is always to disconnect power to the refrigerator before servicing it. There are two ways to do this:
- Unplug the appliance – Unplug the power cord from the electrical outlet. This removes electricity flowing into the fridge. Make sure to pull straight out on the plug, not the cord itself.
- Switch off the circuit breaker – Locate the circuit breaker controlling the refrigerator outlet and switch it to the “Off” position. This cuts off electricity at the breaker panel.
Turning off power this way prevents the risk of dangerous electric shocks or electrocution. It allows safe access to electrical components once powered down. Never attempt to troubleshoot or repair an appliance while it is still energized or plugged in.
2. Allow the appliance to cool down before working on it
Refrigerators have hot compressors, condensers, and refrigerant lines shortly after running. These components can reach temperatures above 150°F immediately after the unit cycles off.
Before servicing, allow the appliance to fully cool for at least 1-2 hours. This prevents burns from accidental contact with hot surfaces. Additionally, refrigerant lines maintain high pressures after shutting off which takes time to normalize.
Only begin troubleshooting or repairs once the refrigerator is at room temperature. Rushing into a repair risks contact with extremely hot components.
3. Turn off the water supply and keep towels ready
Since you’ll be working with water supply lines, make sure to turn off the water to the refrigerator before beginning. There is often a dedicated shut-off valve behind or below the fridge. This prevents water leaks if any lines are accidentally disconnected.
Have some spare towels ready as well. Place them under the fridge to soak up any minor water drips or spills when handling lines. Promptly drying any moisture prevents possible water damage issues.
4. Work in a well-lit area, free of clutter and obstacles
Good lighting is essential for seeing inside the appliance and viewing small components. Illumination lets you inspect wiring, connectors, and boards closely. Use a flashlight or headlamp if the area behind the refrigerator is dark.
Clear any obstructions blocking access to the back or top of the unit. Remove items that could get in the way or cause tripping hazards. Make sure to close refrigerator doors to prevent an accidental collision as well.
5. Avoid working with wet hands and keep the work area dry
Moisture and electricity don’t mix safely. Wet hands provide electrical conduction, so avoid servicing an appliance with damp hands. Thoroughly dry your hands if washing up beforehand.
Keep some paper towels on hand to soak up melting frost build-up or minor moisture. Take care not to drip water on any boards or wiring while repairing. Also be mindful of steam from defrost cycles.
6. Follow specific installation or safety instructions from the user manual
Appliance manuals contain model-specific warnings and critical safety steps. Consult the user guide and follow all manufacturer-recommended precautions.
For example, Frigidaire requires discharge of condenser capacitor before service. Make sure to follow their step-by-step process explicitly. Never take short cuts around safety guidelines.
7. Handle parts gently to prevent damage or personal injury
When removing any refrigerator parts or components, handle them with care. Use both hands and move slowly to avoid dropping heavy items like condenser coils. Gently unravel or straighten wires rather than yanking them.
Insert plastic panel fasteners carefully lined up to prevent cracking the liner. Don’t force connectors together to avoid bending pins. Damaged parts may need complete replacement.
8. Wear insulated gloves and avoid touching exposed wires or terminals
Wearing insulated rubber gloves reduces the risk of electrocution from touching live voltage. Never handle exposed wires, terminals, or connections with bare hands. Insulated tools like screwdrivers provide further protection.
Be cautious not to have body contact with grounded metals when working on live circuits. Make sure to avoid any jewelry or watches which conduct electricity as well. Maintain isolation from ground for maximum safety.
9. Take photos or make notes of wiring connections before disconnecting
Before disturbing any wiring harnesses or connectors, take photos or make sketches showing how everything routes and connects. This provides a handy reference when reconnecting wires later.
Label wires with tape indicating their locations if needed. Don’t risk mixing up cabling that may be color-coded differently. Tracing wiring back to original positions can be very challenging.
10. Don’t test live voltage with a multimeter if unfamiliar with short-circuiting prevention
Using a multimeter to measure live voltage requires special precautions. Touching the two probes together while in the voltage testing mode can short the circuit. This may blow a fuse or cause a spark and electrical hazard.
If inexperienced with meter probe usage, avoid testing energized circuits. Take an electronics course to properly understand short-circuit prevention before probing live voltage. Alternately, test voltage with the power disconnected for safety.
Steps to Clear the Er CE Error Code
Got the annoying Er CE error on your Frigidaire refrigerator? Let’s walk through the troubleshooting steps to fix this issue and get your ice maker working again. Follow along to learn how to diagnose and repair the problem:
Step 1 – Reset the refrigerator
As a first step, perform a simple power reset:
