Below are some refrigerator repair and troubleshooting pointers to help you get more life from your refrigerator and keep it operating like new.
Like any appliance, refrigerator care is necessary to keeping it functioning economically. A number of appliance maintenance chores are equally necessary for essential safety and longevity. This information relates to most brands and styles of refrigerators.
Caution! Appliance repair and troubleshooting might be hazardous for the common homeowner. Reduce chance of demise or injuries by disconnecting the appliance just before making repairs. Appliances may have sharp edges so use caution when doing work inside the appliance. When doubtful, get in touch with a trained appliance service professional for help and support.
The majority of domestic refrigerators operate the same. All come with a compressor, condenser, evaporator, capillary tube and a thermostat. Refrigerators take warmer air and turn it into cold by removing the heat utilizing evaporation processes.
The compressor is really the hardest working part of the refrigerator and is managed by the thermostat. It compresses refrigerant gas, causing it to heat and pressurize as it circulates through the condenser coils to dissipate warmth and condense it into a liquid.
The condenser coil is a system of conduits going through thin pieces of metal appearing like fins. The pressurized gas from the compressor continues into the condenser coils and changes to liquid while the conduits transmit heat from the coils by the fins attached to the tubes. The capillary tube controls the pressure of the refrigerant as it penetrates the coils.
As the refrigerant passes through the capillary tube the liquid expands until it evaporates to develop into a cool, low-pressure gas. The cold gas progresses through the evaporator coils to allow the gas to take in heat; thereby, chilling the air moving past the coils. The fan inside the freezer chamber disperses the air to help keep the temperature regular. The operation continues to repeat itself, regulated by the thermostat, to help keep frozen foods at a constant temperature to preserve freshness.
Modern refrigerators have a self-regulating defrost technology that includes three main factors; the defrost timer, defrost thermostat and defrost heater. Every 6-12 hours, the defrost timer cuts the power to the compressor and turns on the defrost heater. As the ice liquefies, it filters through a tube into a drip pan where it vaporizes with the help of a fan which blows heated air across it.
Refrigerator and Freezer Troubleshooting Tips:
Refrigerator not operating at all: Check the power supply. Ensure the electrical outlet is functioning properly by plugging another thing into it. Check fuses or circuit breakers. If this isn't the issue, it may be a variety of items like the compressor, overload/relay, regulator or wiring.
If the power source is ok, refer to the troubleshooting page of the owner's manual. Do not set this aside; read it to learn efficient ways to care for your refrigerator before anything happens. Appliance handbooks have preventative maintenance tips and operating instructions that ought to be followed to ensure operation. Talk to a qualified appliance repair specialist to analyze and repair refrigerator issues if the manual does not give you the remedy.
Food not frozen steadily: This is not an uncommon disorder. To begin with, verify the temperature which needs to be anywhere between -10 F and +10 F. Refrigerator temperatures must be 36F to 45F. Balance the temperature appropriately.
Try redistributing the food as temperature levels can be different in various areas. Look for a worn out gasket by placing a sheet of paper between the gasket and framework as you close the door. If it pulls out easily, you are in need of a fresh door gasket.
Refrigerator Runs far too much: The thermostat commands the compressor, turning it off and on as required. The compressor will continue to run until the temperature level is below the thermostat setting.
A new refrigerator will run a long time, pretty much constantly, until it cools enough to preserve the chosen temperature, about 24 hours. Keep the refrigerator around half to two-thirds full to help maintain a steady temperature level. If you have a small family and can not keep it full, fill up the space with jugs of water. The cold things inside will help sustain the temperature as the door gets opened and closed.
Make sure the refrigerator has air clearance all around it. Refrigerators that have a condenser coil on the back must have clearance to emit heat away from the coils. Be sure the light is shutting off when the door is closed because it can warm up the interior of the refrigerator. Press the button with the door open and if the light remains on, fix or change the switch.
The refrigerator will certainly run more often if the space is hot and humid or if you just placed a great deal of warm food into it. If the compressor will not turn off when the temperature is cold enough, it may need to be replaced. A refrigerator thermometer can help you determine an appropriate setting to keep food cold and protect the compressor from running too much.
If the issue is low levels of refrigerant, you will need to get in touch with an appliance service professional who is EPA certified to handle a sealed unit. Undertaking to deal with this problem yourself will likely void the warranty.
