Are you experiencing frustration with your Kenmore refrigerator, specifically with the defrost system not functioning properly? You're not alone. This common issue can be quite troublesome, as it may cause piles of ice and increased energy bills. But don't let this problem frost over your day. We've prepared this guide to help you diagnose and resolve the issue with your Kenmore refrigerator model 795.
Before you start, ensure you have a maintenance manual, some basic tools like a screwdriver, and a few hours to dedicate to this task. Safety first; unplug your refrigerator before starting any work.
Understanding the Defrost System
The defrost system is a crucial component in your Kenmore refrigerator, responsible for melting the frost that builds up inside the freezer. It cycles on and off automatically to maintain a frost-free environment. When this system malfunctions, ice can accumulate, leading to various problems.
A faulty defrost system can cause your food to spoil, increase energy consumption, and, in severe cases, it may even damage other components in your refrigerator. Therefore, it's essential to address this issue promptly.
Common Causes of Defrost System Failure
Several factors can cause your Kenmore refrigerator's defrost system to malfunction. Here are some of the most common culprits:
- Thermostat Malfunction: The thermostat regulates the defrost system. If it's faulty, it may cause the defrost heater to stay on too long or not at all.
- Defrost Timer Issue: The defrost timer controls when the defrost cycle begins and ends. If it's defective, it may cause the defrost heater to operate at inappropriate times.
- Faccumulator Failures: The fautomator, or defrost control board, manages the defrost cycle. In some cases, it may fail, leading to defrost system malfunction.
Inspecting the Defrost System Components
Before you start replacing parts, it's wise to inspect each component to ensure you're addressing the correct issue. Here's a step-by-step guide:
1. Locate the defrost timer, typically behind the rear access panel. Check if it's functioning correctly.
2. Inspect the thermostat. Check if it's reading the temperature correctly and responding to the temperature changes.
3. Check the defrost heater. If it's faulty, it won't heat up when the system is active. Test it with a multimeter to confirm.
4. Inspect the defrost fans. They ensure proper air circulation during the defrost cycle. Ensure they're running smoothly.
Troubleshooting and Repairing the Defrost System
Once you've identified the problematic component, you can move on to replacing it. Here are the steps to replace each part:
Always refer to your maintenance manual for the specific instructions relevant to your Kenmore refrigerator model. Begin by unplugging the refrigerator and disconnecting the wires from the faulty component. Remove the part and replace it with a new one. Ensure you connect all wires back correctly.
Replacing the Defrost Timer
1. Disconnect the power source to your refrigerator.
2. Access the defrost timer, usually located at the back of your refrigerator.

4. Take note of the wire placement before removing the old timer.
5. Install the new defrost timer, ensuring all wires are correctly connected.
Replacing the Thermostat
1. Turn off your refrigerator's power.
2. Locate the thermostat, usually near the freezer compartment or at the back of your fridge.
3. Remove the wire harness from the thermostat.
4. Install the new thermostat, ensuring all wires are correctly connected.
Replacing the Defrost Heater and Fans
Follow similar steps to replace the defrost heater and fans. Ensure you're connecting all wires back correctly and that the components are secured appropriately.
If you've replaced the faulty component and your Kenmore refrigerator's defrost system still isn't working, it might be best to contact a professional for assistance. Regular maintenance and timely repair can extend the lifespan of your refrigerator and prevent inconveniences like this in the future.
