When it comes to appliances, most people have a tendency to pay more attention to anything else when they shop: price. Unfortunately, finding cheap appliances doesn't always mean you will find good appliances. As an income property owner, I have purchased several different appliances over the years, and I can tell you first hand that not all brands are created equal. My blog is dedicated to helping you to find appliances that you will actually be able to use, abuse, and love for a long time. Check out my blog for information on what to look for, how to shop, and where to get great deals.
If your refrigerator or freezer is too warm, it won't be able to preserve food effectively and could cost you a lot of money. Read on to learn what could cause this problem and how to fix it.
This is a temperature controlled switch that turns on the compressor and fan circuits whenever temperatures rise, allowing the fresh food and freezer area to remain cool enough to preserve your food. If this switch is defective, then you may notice that your compressor isn't running for long enough, causing the refrigerator to get too warm.
Check to see that the wire terminals on the cold switch aren't corroded or loose and have them fixed if defective to ensure uninterrupted supply of power to the compressor. You should also ensure the sensing bulb on the switch isn't out of position or obstructed by dust or other debris.
Another likely cause of a refrigerator that's too warm is a damaged evaporator fan. This is usually located in the freezer compartment and is designed to circulate cold air from the compressor throughout the fridge. If the fan fails, then you will have temperatures in the freezer compartment start to rise and notice the compressor running more frequently to try and keep the appliance cool. If you don't hear the evaporator fan running when the compressor is on, this could also be a sign that it has stopped working.
The evaporator fan could be defective due to a loose blade, so open the fan cover and check that the fan blade is secured tightly to the motor. Next, verify that the fan motor can move freely and isn't obstructed by dirt. Vacuuming it can remove any debris lodged inside and get it to run smoothly. Finally, check if power is reaching the fan motor by testing it for continuity with a multi-meter.
The defrost timer is designed to control the compressor circuit and defrost circuit, turning off power to the compressor and refrigerator fans for a few minutes to allow the freezer compartment to defrost and then turning restoring power once again to allow for continued cooling.
If the timer is defective, it may fail to terminate the defrost cycle, leading to soaring temperatures in the freezer compartment. Typically, the timer will be located on the control panel in the fresh food compartment or at the bottom of your appliance behind the kick plate. Check the power terminals on the timer for continuity or have a refrigerator repair expert replace it with a new one if damaged.
