Parts of a Refrigerator

There are not many homes that do not feature a refrigerator in the kitchen. It has been a must-have household appliance for several years now. A household refrigerator stores food at the right temperature, to reduce spoiling and stop the growth of harmful bacteria. The process of refrigeration starts by distributing the heat from inside of the refrigerator to the exterior, by relying on principles of evaporation and condensation.

The primary components of a refrigerator are. For questions or service call Tuscaloosa Appliance Repair:


The compressor is a combo of a motor and pump, and it is responsible for the circulation of refrigerant in the system.
The compressor is an important piece of a refrigerator. You should call a professional company if the compressor isn’t working.


The condenser is found on the back outside wall of the appliance and will help to disperse the heat absorbed from within the refrigerator then out to the surrounding air.


A refrigerator evaporator is stored on the inside of a refrigerator where absorbs heat contained within it, thereby lowering the interior temperature.

Right when an evaporator stops working, it’s time to hire a professional. Don’t wait until it is too late.

Expansion Device

Liquid refrigerant is transferred through a capillary tube which serves as an expansion tool to cool the gas, thereby transforming the gas back into liquid.


A refrigerator thermostat helps regulate the current temperature in the interior of the refrigerator, beginning a new cooling cycle as necessary.

A thermostat inside of a refrigerator is very prone to malfunction. Troubleshoot and hire a technician in Tuscaloosa for service right after a problem happens.

How Does Refrigeration Work?

1. Right when the temperature in the interior of the refrigerator rises above the set point sensors alert the compressor to begin, and the cooling cycle starts. The refrigerator collects the cold liquified refrigerant, then condenses and pressurizes the liquid, and raises the temperature, so it can turn into a gas form.

2. The refrigerator compressor unit directs the hot gas towards the condenser coils located on the exterior of the unit, at which point it comes into contact with the lower temperature in the kitchen and reverts to a liquified form.

3. The cool refrigerant then continues on its journey towards the refrigerator evaporator component, pushing through the coils within the appliance and top freezer compartment.

4. The liquid absorbs the warm air from inside the appliance, thereby lowering the temperature back to the correct final point.

5. The liquid then will evaporate, and turns back to a gas, and returns to the refrigerator compressor unit so it can then continue the cooling cycle.

Refrigeration technology is often used in several applications and large appliances, this includes heat pumps, AC units, refrigerators and freezers. By extracting warmth from a single place and then transferring it to elsewhere the cycle of refrigeration aids in cooling a house, provides a perfect space for food that is perishable, and helps with the manufacturing and storage of a lot of different common products and goods.

3. Clicking Igniter on Stove

If the igniter on your gas-powered oven clicks nonstop and the burner will not light, inspect to make sure your burner top is on tight and correctly aligned. You may possibly notice this if you’ve had a recent boil over or spill on the stovetop.

Otherwise, the cause is probably a clogged igniter. To clean , first remove the burner top and clear off any dirt. You can also use a metal clothes pin to pick debris from the grooves. If that doesn’t eliminate the problem, it’s best to not take a lighter apart unless you have the training; in this case hire a professional appliance repairman to investigate the issue.

4. Broken Garbage Disposal

A sink’s garbage disposal has self-protection with its own overload trip switch. If it becomes clogged, overheats, runs for too long, or has a different problem, your garbage disposal could just have to be reset instead of fixed. First, please make sure the switch is OFF. Then, find the reset button on the disposal beneath the kitchen sink and then press the switch. If the button will not stay pushed in, wait a few minutes and press it again. Turn on the water and then turn the switch on.

If the garbage disposal is clogged with food and you hear nothing but a humming sound rather than the grinding of food, you could need to manually twist the disposal blades with a hex key to eliminate the jam. Next, push in the reset button to get the disposal running again. If these tips are unable to get the appliance working like normal, please don’t succumb to the urge to push one of your hands down in the system to troubleshoot. Be smart and set up an appointment with a professional appliance repairman in Tuscaloosa.

5. No Power from Outlet

In the kitchen or bathroom, the electrical outlets should be installed with GFCI capabilities in order to protect from harm in wet environments. If a GFCI electrical outlet isn’t generating power, push the red button to see if that restores power.

If it doesn’t, or if you are trying a basic outlet, make certain that a breaker has not been tripped in the home’s circuit breaker box. If you are uncertain if a breaker was tripped, flip it to the OFF position and then flip it back onto the ON position. But remember, safety by electricity is critical. Should you have doubts, call a professional repairman.

6. Wobbling Washing Machine

A wobbling washing machine {can|will often create quite a loud racket and isn’t a productive method to get clean clothes. If your washing machine starts banging, the appliance could be broken. To fix this issue, rotate the legs of the washing machine to lower or lift each corner until it’s balanced. One other likely scenario is the unit is off balance. Crack open the lid and arrange the shirts and pants so that they’re dispersed in the drum{| of the washing machine.

Doing this should help your washing machine not need to work as hard. If you do attempt to arrange the clothing a couple of times without success, do not ignore the problem. You could have a loose drum or motor mountto fix, which can be easy enough for a professional repairman to fix. But continuing to use the washer with this issue might damage other parts and cause a more costly repair in the future.
