What could be causing my Whirlpool fridge to not cool while the freezer works?
The issue of a Whirlpool fridge not cooling while the freezer functions properly can often be attributed to a few common causes. The most prevalent reason is an obstruction in the airflow between the fridge and freezer compartments. If the vents that allow cold air to flow from the freezer into the refrigerator are blocked by food items or frost buildup, this can significantly impede cooling in the fridge section.
Another likely cause could be a faulty thermostat or temperature control board in the refrigerator. If the thermostat is not reading the temperature correctly, it could be preventing the cooling cycle from starting in the fridge compartment. Moreover, problems with the compressor or start relay can also hinder proper cooling, so exploring these components may yield insights into the issue.
How can I check if the vents are obstructed?
To check for airflow obstruction, start by inspecting the vents located inside your fridge. These are often situated at the rear or side walls and can be easily blocked by food items, containers, or ice buildup. Remove any items that may be blocking these vents and see if that improves the cooling performance.
If you find ice buildup around the vents, it may indicate a defrost system issue that requires attention. You can manually defrost the freezer by unplugging the fridge or using a hairdryer on a low setting to melt the ice. Allow the refrigerator to return to its normal temperature after the obstruction is addressed to see if the cooling improves.
What should I do if the compressor is not running?
If you suspect that your Whirlpool fridge’s compressor is not running, the first step is to listen for any humming sounds coming from the back of the fridge. If there’s no sound, you may need to inspect the unit’s power supply to ensure it’s plugged in properly and that there are no tripped circuit breakers.
