Most common repairs needed to fix a KitchenAid refrigerator
Compressor Start Relay Replacement
A faulty compressor start relay could be the reason your refrigerator is not freezing. The compressor start relay helps the compressor kick on and run, which is essential for cooling the refrigerator. If the start relay isn't working correctly, the compressor may fail to start or run intermittently, leading to inadequate cooling and a rise in refrigerator temperatures. You might notice that your food isn't staying frozen or that the refrigerator compartment feels warmer than usual. To address this issue, check the compressor start relay for any signs of damage or wear. If you suspect the start relay is the problem, schedule an in-home repair appointment through Sears Home Services to have a technician inspect and replace the faulty relay, ensuring your refrigerator maintains the proper freezing temperatures.
Compressor Replacement
A locked refrigerator compressor can exhibit several symptoms indicative of a malfunction. The most noticeable sign is a lack of cooling in the refrigerator compartment, leading to elevated temperatures and the potential for food spoilage. The freezer may also fail to maintain the desired freezing temperatures, resulting in no ice production from the icemaker or dispenser. Additionally, you'll observe that the compressor is unusually silent or fails to produce its typical humming sound during operation. In some cases, the compressor may attempt to start but fail, resulting in repeated clicking noises. The inability of the compressor to circulate refrigerant properly can affect the defrosting process, leading to ice buildup in the freezer. Furthermore, a faulty compressor could send a sudden influx of melting frost to the drain line, causing it to back up, preventing adequate draining, and potentially causing water leaks.
Electronic Control Board Replacement
A malfunctioning electronic control board can lead to various failures in a refrigerator, including a lack of power or cooling. This is because the board serves as the brain of the refrigerator. The board controls crucial operations such as regulating internal temperatures, running fans, managing defrost cycles, overseeing the icemaker, and controlling dispenser functions. If the PCB malfunctions, it can disrupt communication between many different components, including automatic doors if equipped. A failing board may cause a chattering or clicking noise from the refrigerator and may emit a burning odor. Due to the potential impact on multiple components, it is advisable to have a Sears Home Services professional conduct diagnostic tests on the board to confirm if replacement is necessary.
Why is both my fridge and freezer not cooling?
Check for power
First, check to see if your refrigerator has power. If the control panel is dead or the interior light won’t turn on when you open the door, reset the house circuit breaker to see if the fridge will power up.
If the refrigerator doesn’t power up after resetting the breaker, test the electrical outlet for power by plugging a night light or similar item into the outlet to check for power. If the outlet is dead, have an electrician fix the outlet.
Troubleshoot compressor problems
When your refrigerator has power but the compressor isn’t running, follow the tips in this DIY video to troubleshoot compressor problems that will prevent the fridge from cooling:
Check the compressor start relay
Remove the machine compartment cover and check the condenser fan. If the condenser fan runs, then your compressor should be getting power because the compressor shares a circuit with the condenser fan motor on almost all refrigerators.
Unplug the refrigerator and unhook the start relay retainer clip. Pull the compressor start relay out of the refrigerator. Shake the start relay to see if it rattles. If it does, that's a tell-tale sign the relay is fried. Replace that part and your refrigerator may begin working again.
If the start relay doesn't rattle, you’ll need to check for continuity to confirm that it’s bad. Put the one meter lead into terminal 5 and the other meter lead into terminal 6.
If you detect an open circuit between those terminals then the meter will read 1 in the far left digit. You’ll need to replace the PTC relay.
If the start relay's okay, then you may have a defective compressor. Unfortunately, you’ll need to get a service technician’s help to replace a compressor, because that repair involves recovering Freon.
Check for thermistor problems
If your condenser fan wasn’t running, then you may have a defective electronic control board or a bad thermistor (temperature sensor).
Testing a thermistor in a refrigerator is fairly simple. Follow the steps in this DIY video to test the thermistor(s) in your refrigerator and/or freezer compartments:
Replace a thermistor if it isn’t working properly. This may restore cooling in your refrigerator.
If the compressor start relay and thermistors in the refrigerator are okay, then a problem with the electronic control board or a wiring failure may be preventing the compressor from running.
Follow the remaining troubleshooting tips in the video to find and fix the cause of the compressor failure or have a service technician visit your home and fix the fridge if you’re not able to repair the problem yourself.
What to expect when you experience a KitchenAid refrigerator freezer not working issue
How is the refrigerator freezer not working fixed?
Correcting most refrigerator freezer not working involves replacing the compressor start relay, compressor, or PCB. However, there are many potential causes, so a thorough diagnosis is key to fixing the problem. An accurate diagnosis is essential to understanding how much the repair will be.
Sears Home Services recommendations for a refrigerator freezer not working problem
When a refrigerator freezer is not working, it can be for many reasons. To avoid replacing unneeded parts, we recommend having a Sears Home Services professional perform diagnostic tests to identify the root cause of the problem. Our technicians are experienced at diagnosing all types of refrigerator failures.
What to look out for with a refrigerator freezer not working diagnosis
Diagnosing modern appliances without proper knowledge and training can be difficult. Without using proper diagnostic techniques, fixing your refrigerator problem will only be achieved through changing parts on a hunch. Appliances, especially in the last 10 years, have become extremely advanced, and many models have electronic parts that are difficult to test. DIY repairs on the latest appliance models are becoming increasingly difficult.
