Kenmore Side By Side Refrigerator Not Defrosting

Introduction

Is your Kenmore side-by-side refrigerator struggling to keep your frozen goods frozen? Have you noticed ice buildup in the freezer section? A refrigerator that isn’t defrosting properly can lead to wasted food, increased energy bills, and a frustrating appliance experience. When the defrost system fails, ice accumulates, blocking airflow and preventing proper cooling. Addressing this issue promptly is crucial to avoid food spoilage and costly repairs. This guide will walk you through simple troubleshooting steps to get your Kenmore refrigerator back to its optimal performance. Don’t worry, you don’t need to be an expert to fix this!

Common Causes of Kenmore Side by Side Refrigerator Not Defrosting

Several factors can cause your Kenmore side-by-side refrigerator to stop defrosting. Here are some of the most common culprits:

Defrost Timer Malfunction: The defrost timer controls when the defrost cycle begins. If it’s faulty, the cycle might not start at all.
Defrost Heater Failure: The defrost heater melts the frost buildup. If it’s burned out, it can’t do its job.
Defrost Thermostat Problems: The defrost thermostat monitors the temperature of the evaporator coils. If it’s defective, it might not signal the heater to turn on.
Blocked Defrost Drain: A clogged drain can prevent melted frost from escaping, leading to ice accumulation.
Faulty Thermistor: The thermistor senses the temperature inside the refrigerator and freezer, relaying the information to the control board. A faulty thermistor can cause defrosting issues.
Damaged Wiring: Loose or damaged wiring connections to the defrost components can interrupt the circuit and prevent them from working.
Control Board Issues: The control board manages the entire defrost system. A faulty control board can cause various defrosting problems.
Door Seal Problems: If the door seals are damaged, warm, moist air can enter the freezer, leading to excessive frost buildup.

Symptoms Checklist

If you’re experiencing defrosting problems, check for these symptoms:

Excessive ice buildup on the back wall of the freezer.
Food in the freezer isn’t staying frozen.
Unusual noises coming from the refrigerator (e.g., a clicking sound).
Water pooling on the floor near the refrigerator.
The refrigerator is running more frequently than usual.
The freezer temperature is fluctuating.

How to Fix Kenmore Side by Side Refrigerator Not Defrosting Step-by-Step Guide

Follow these steps to troubleshoot your Kenmore side-by-side refrigerator’s defrosting problem:

Unplug the Refrigerator: Before starting any repairs, unplug the refrigerator from the power outlet to prevent electric shock.
Inspect the Freezer for Ice Buildup: Take a close look at the back wall of the freezer for excessive ice accumulation. This confirms a defrosting issue.
Locate the Defrost Timer: The defrost timer is usually located behind the kick panel at the bottom front of the refrigerator or behind the control panel. Consult your refrigerator’s manual for the exact location.
Manually Advance the Defrost Timer: Use a screwdriver to slowly turn the defrost timer clockwise until you hear a click. This forces the refrigerator into the defrost cycle.
Listen for the Defrost Heater: After manually advancing the timer, listen for a humming or sizzling sound, which indicates the defrost heater is working.
Check the Defrost Drain: Locate the defrost drain hole at the bottom of the freezer compartment. It’s usually a small hole leading to a drain tube.
Clear the Defrost Drain: Use a turkey baster filled with warm water to flush out the drain. You can also use a long, flexible object like a pipe cleaner to dislodge any debris.
Inspect the Door Seals: Check the door seals for cracks, tears, or gaps. A damaged seal can allow warm, moist air to enter the freezer, leading to ice buildup.
Clean the Door Seals: Use a damp cloth to clean the door seals. This will help them create a tighter seal.
Check the Condenser Coils: The condenser coils are located at the back or bottom of the refrigerator. Clean them with a vacuum cleaner and a brush attachment to remove dust and debris.
Plug the Refrigerator Back In: After completing the troubleshooting steps, plug the refrigerator back into the power outlet.
Monitor the Refrigerator’s Performance: Observe the refrigerator over the next 24-48 hours to see if the ice buildup disappears and the temperature stabilizes.

Fix the Issue Without Buying Parts

Before considering replacement parts, try these free methods:

Reset the Refrigerator: Unplug the refrigerator for 30 minutes, then plug it back in. This can sometimes reset the control board and resolve the issue.
Clean the Refrigerator Thoroughly: Remove all food items and clean the interior of the refrigerator, paying attention to the freezer compartment.
Inspect Wiring Connections: Check the wiring connections to the defrost components for any loose or damaged connections. Secure them if necessary.
Ensure Proper Ventilation: Make sure the refrigerator has adequate space around it for proper ventilation.
Avoid Overloading the Refrigerator: Overfilling the refrigerator can restrict airflow and affect its performance.

When Replacement Might Be Necessary

If you’ve tried all the troubleshooting steps and the refrigerator still isn’t defrosting, the defrost heater ($30-$70 USD), defrost timer ($20-$50 USD), or defrost thermostat ($15-$40 USD) might need to be replaced. In rare cases, a faulty control board ($80-$200 USD) may be the culprit, but consider that a last option. Consider contacting a qualified appliance repair technician for assistance before replacing any parts, as they can diagnose the problem accurately and recommend the appropriate solution.

Safety Warning

Always unplug the refrigerator before performing any repairs.
Avoid working on electrical components if you’re not comfortable with electrical work.
Be careful when handling tools to prevent injuries.
Keep the work area clean and dry to avoid slips and falls.
Never touch electrical components with wet hands.

Tools You May Need

Screwdriver (Phillips and flathead)
Vacuum cleaner with brush attachment
Turkey baster
Pipe cleaner or wire
Damp cloth
Multimeter (optional, for testing electrical components)
