Why Does My GE Profile Refrigerator Make a Pulsing Sound?
Asked Dec 15, 20150 views1 answer
I am experiencing a pulsing sound coming from my GE Profile refrigerator, model PSS26LGRCC WW, while it is running. Despite this noise, it is still cooling properly. I haven't tried any troubleshooting steps yet, but I seem to recall that it might need a new motherboard. Can anyone provide insight or advice on this issue?
Understanding the Pulsing Sound in Your GE Profile Refrigerator (PSS26LGRCC WW)
Experiencing a pulsing sound from your GE Profile refrigerator can be concerning, especially when everything seems to be cooling properly. This guide will help you identify potential causes and provide troubleshooting steps to resolve the issue.
Common Causes of Pulsing Sounds
-
Compressor Activity
- The compressor is a vital component that can make a variety of noises during operation. A pulsing sound can often be attributed to normal compressor cycling, especially when it is trying to maintain the set temperature.
-
Evaporator Fan
- If the sound appears to be coming from the freezer, it may be related to the evaporator fan. This fan circulates cold air throughout the refrigerator and freezer compartments. A malfunctioning fan can produce unusual sounds.
-
Thermistor Issues
- The thermistor monitors the temperature inside the refrigerator and informs the control board when to activate the compressor and fan. If the thermistor is not making good contact or is faulty, it can lead to erratic compressor activity.
-
Motherboard Malfunction
- While less common, a failing motherboard can cause irregularities in the refrigerator’s operation, including unusual sounds. However, this is typically accompanied by other symptoms, such as erratic temperature control.

If the pulsing sound you're hearing from your GE Profile refrigerator model `PSS26LGRCC WW` seems to be coming from the compressor, it could actually be related to the evaporator fan. A common issue is that the thermistor, which is responsible for monitoring the temperature, can become loose. It's typically held in place by a zip tie from the factory, and if it doesn't make good contact with the evaporator, you might hear that pulsing noise.
To check this, locate the thermistor, which is the white peg on the evaporator at the top. Make sure it's securely attached and making proper contact. If it looks okay but the problem persists, consider looking into the evaporator motor. Sometimes, replacing the motor can resolve the issue entirely.
It sounds like you've already taken some steps by checking the thermistor and even replacing the evaporator motor, which seems to have worked for you. If the pulsing sound returns or if you encounter any other issues, just revisit those components to ensure everything is functioning as it should.
