You settle into your favorite chair and press the button on the remote. Evaporation is an endothermic process, which means it draws heat from the surroundings. It can be difficult to measure the exact temperature of the inside of the compressor. Dust and debris interfere with air circulation and amplify the heat generated by the compressor. While it is definitely handy to have an appliance thermometer in your home, it isn’t necessarily something that you will find in most homes. A recip that is running too hot will surely fail before its time. Ryan also loves hockey and a lifelong Buffalo sports fan. That indicates a possible problem with the compressor, and if so, you'll probably notice the temperature inside the refrigerator going up. Condensers should be cleaned regularly to keep them operating at their rated capacity. There are several other components which are more likely to be defective if the compressor doesn't work. (Find Out Now!). To begin, pull the fridge off of the wall and find the compressor’s location; this is generally near the floor somewhere. There are plenty of other reasons why your fridge may be working improperly or not at all. When your refrigerator is working the way that it should, the internal temperature will be cold enough to keep your food at a safe temperature. The compressor is a motor which compresses the refrigerant and circulates the refrigerant through the evaporator and condenser coils. Measuring the Temperature of the Discharge Line, Checking the Internal Temperature of the Compressor. The Safest Neighborhoods In San Francisco: 2020’s Ultimate List. Auto Defrost System Not Working Properly Having a fridge or freezer with an auto-defrost feature is a nice thing to have. This causes the compressor's coils to contract, and the gas can become trapped. Food will begin the spoiling process when the temperature in the refrigerator starts to climb above 40 degrees. The movement of the piston – there are other compressors that have gear systems – is what generates heat. When the compressor goes bad, it can be a fairly expensive repair. When food warms up to that temperature, the clock is ticking. If the temperature rises to 320 degrees, the refrigerant will start to break down. Unplug the refrigerator and remove dust with a vacuum, a rag or a compressed air blower. Sometimes, as the gas refrigerant moves through the compressor, the back of a fridge can get extremely hot. In many cases, system problems and compressor failures are directly related to high discharge temperatures. The compressor needs to have a consistent supply of lubricant to keep it from overheating due to the constant motion. Also the front trim piece between the freezer and fridge is getting hot as well. That said, you need to be able to determine the temperature of your fridge in the event of a malfunction with any of the various components. It's fairly easy to measure the temperature of the compressor yourself. This is part of the process that takes the hot gas created by the compressor and turns it into the cool liquid that ultimately makes your refrigerator cold. If your refrigerator is working properly, it should be cold inside and there should be warmth behind or underneath it. If the unit has stopped cooling, check to see if the fan motor, if it has one, has stopped running. When the condenser coils aren’t working as they should, it will be difficult to keep the fridge at the proper cool temperature. Most compressors work through reciprocating action. The tubing from the discharge line at that 6-inch difference will generally be somewhere between 50 and 75 degrees lower than the internal temperature of the compressor. There is a fairly simplistic way to check to see if the compressor is working properly. And the compressor is very hot to the touch. Not much air seems to be coming from the vents on the fridge side. 1. Generally speaking, produce can survive in a fridge after a power outage for a couple of hours, but dairy should be watched carefully. It is imperative that your refrigerator be kept at an optimal temperature. A little from the upper vent. When the compressor goes bad on your fridge, there is a decision that needs to be made. A piston cycles back and forth, pumping refrigerant into the coil on the forward stroke, and a valve prevents the refrigerant from flowing backwards when the piston retracts. The cooling inside a refrigerator or freezer compartment is a result of the evaporation of a refrigerant inside a system of coils. Check your refrigerator thermostat to be sure it is set at an appropriate temperature. If it stops running, the compressor will get very hot and the overload will shut the compressor … Pull the refrigerator away from the wall and locate the compressor, which is usually near the floor. Start by pulling the fridge away from the wall slightly to get a better look at the coil. Refrigerator Compressor Fan Stops. If the condensation on the outside of the container disappears in short order, the water is very cold, and the temperature of the fridge is likely okay. The way that a compressor works, most of the heat gets generated at the discharge port of the compressor. A compressor can run hot for a variety of reasons, including lack of refrigerant in the appliance or a refrigerator thermostat that is set too low, thus causing the compressor to work too hard. The discharge tube is the warm one; the other one contains vapor and should feel cool. For evaporation to happen correctly, the refrigerant has to be pressurized so that it turns into a liquid. The compressor started up fine last night. Servicing the refrigeration system, including the compressor, requires a license, so it isn't something you can do yourself. Without a doubt, the hardest working part of the fridge is the condenser coils. I understand your concern about the compressor. If your fridge begins to work and your compressor isn’t overly hot, it was likely just the excessive dust causing the problem. For this evaporation to happen, the refrigerant has to be pressurized in its liquid form so it will evaporate when it passes through a tiny aperture in the coil system. Still nothing. He worked as an expert consultant with eHow Now and Pro Referral -- a Home Depot site. Should the compressor’s temperature get to be more than 350 degrees, the lubricating oil that is inside of the compressor will begin a degradation process. And the freezer side is getting cold. The freezer, on the other hand, should be set to 0 degrees Fahrenheit. While the compressor is one of the most common culprits, there are other components that can break down over time and keep your fridge from working properly. It's normal for this temperature to be as high as 300 degrees Fahrenheit, but it should never be higher. There are steps to identify these problems as they occur and, for the most part, can be remedied fairly easily. These are not only far more accurate for measuring your fridge’s temperature, but they are pretty inexpensive as well. How it Works: If the refrigerator is not cold enough, the compressor might be defective. By creating an account you agree to the Hunker, HVACR News: Reasons Behind Compressor Overheating, Parker: Compressor Overheating Is the Number-One Refrigeration Problem. Is it Worth Replacing a Compressor on a Refrigerator? Should the temperature be higher than the outlined safe temperatures from above, the most likely cause is poor ventilation. You can get a pretty good idea of what that temperature is by measuring the discharge line’s temperature. If they’re shot, you have to replace them entirely. It's difficult to measure the temperature inside the compressor, but you can get a fairly accurate idea by measuring the temperature of the discharge line about 6 inches away from the compressor. A common cause of premature reciprocating compressor failure is overheating. The most common reason for the condenser coils to stop working is that they are clogged up with dirt, dust, or other kinds of debris. When the temperature gets to be 320 degrees or more, this is the point that the refrigerant starts to break down and lose effectiveness. It's also possible the compressor is too dirty. He has degrees in science and humanities and years of teaching experience. The other tub will hold vapor inside and it should feel cool to the touch.
