Porque el compresor de mi refrigerador no arranca y como solucionarlo

The compressor of your refrigerator is not starting, and you're left with a bunch of spoiled food and a big problem. This is a common issue that can be caused by a faulty thermostat, which can be found in section 3 of our article, where it's explained that the thermostat helps regulate the temperature inside the refrigerator and can fail over time.

A faulty overload protector is another possible cause, as mentioned in section 5, where it's stated that this device is designed to prevent the compressor from overloading and can sometimes malfunction, causing the compressor to not start.

The age of your refrigerator is also a factor, as seen in section 2, where it's noted that compressors typically last for around 10-15 years before needing to be replaced.

The compressor is the heart of your refrigerator, and if it's not starting, it can be a real problem.

Faulty thermal overload protector is a common cause of compressor failure, often due to a blown fuse or a tripped circuit breaker.

A malfunctioning capacitor can prevent the compressor from starting, so it's essential to check this component if you suspect a problem.

Low refrigerant levels can also cause the compressor to malfunction, as it struggles to cool the refrigerant.

In some cases, a faulty relay or contactor can prevent the compressor from receiving the power it needs to start.

The parts that make up the motor of your refrigerator are crucial to its proper functioning. The compressor is the most important component, responsible for compressing the refrigerant gas.

The compressor relies on several key components to work efficiently. These include the relay starter, condenser electrico, protector termico, and bobinas internas. Here's a breakdown of each:

The relay is a small but crucial component in your refrigerator's system. It's mounted next to the compressor and provides energy to the running and starting windings for a fraction of a second during startup to help the compressor function.

If the relay is faulty, the compressor may work intermittently or not at all, and the refrigerator won't cool properly. You'll need to replace the relay if it's defective.

Here are the steps to troubleshoot and replace a faulty relay:

Remember, it's essential to follow the correct order of testing and replacing components to avoid wasting time and effort.

The ventilador, or fan, plays a crucial role in keeping your refrigerator cool. It's responsible for directly cooling the compressor by collecting and removing the heat stored in the fridge.

A faulty ventilador can be a major contributor to a refrigerator that's not cooling properly. This is because the ventilador is designed to efficiently remove heat from the compressor.

The motor of a refrigerator is a complex system, but let's break it down into its main components.

The compresor is the most crucial part of the motor, responsible for compressing the refrigerant gas. It's the heart of the system.

The relay starter helps get the motor going by providing an initial electric boost. This makes it easier to start the motor.

The condenser stores energy to ensure a smooth and efficient startup. This is especially important in refrigerators that rely on frequent on-and-off cycles.

A protector thermal prevents overheating by shutting off the motor if it detects high temperatures. This is a safety feature that prevents damage to the motor.

The internal coils generate a magnetic field that drives the piston or rotating mechanism of the compresor. This is a critical function that requires precise control.

Here are the main parts of the motor:

The compresor of your refrigerator not starting can be due to several reasons. One possible cause is a faulty inverter board, which is a common issue in modern refrigerators. This board is responsible for modulating the power supplied to the compressor and can be difficult to troubleshoot.

To identify the problem, check the voltage input to the inverter board. According to the manufacturer's instructions, the board requires a 120 V AC supply and a 4-6 V DC supply from the main control board. If either of these voltages is missing, the inverter board will not function.

Another possible cause of the compressor not starting is a faulty thermostatic sensor or termistor. This sensor controls the temperature of the air and is connected to the control board. If the termistor is faulty, the refrigerator may not cool properly or may continue to cool continuously.

The bobinas del condensador are a crucial part of your refrigerador's cooling system. They can become clogged with polvo and escombros, making the refrigerador less eficiente and harder to cool.

As you inspect the bobinas, you'll notice they're located at the back and bottom of your refrigerador. Make sure to check them regularly to prevent any potential issues.

If the bobinas are dirty, it's essential to clean them with a cepillo para serpentín del condensador and aspire. Be careful not to damage the tubos while doing so.

A dirty condensador can cause mal funcionamiento, which may be due to the suciedad acting as an aislante and altering the enfriamiento system.

A faulty termistor can be a major issue with your refrigerator's ability to cool properly. The termistor is a sensor that controls the air temperature and is connected to the control board.

If the termistor is defective, the refrigerator won't cool (or may continuously cool). To diagnose the problem, you'll need to remove the termistor and test its continuity with a multimeter. This is usually done when the termistor is at 46°F (7°C) or colder.

You can place the termistor in a cup of ice water to cool it down if it's above the desired temperature. If the reading isn't between 10 and 15 kΩ, you'll need to replace the temperature sensor.

Here's a quick checklist to help you troubleshoot the issue:

By following these steps, you should be able to identify and fix the issue with your refrigerator's termistor.

A defective condenser can cause a refrigerator to not cool properly. If the condenser is faulty, it can prevent the compressor from getting enough power to start up.

The condenser of start-up serves as a battery, giving the compressor a boost of power during start-up. If it fails, the compressor may not be able to start up and function as it should.

If the condenser of start-up smells burnt, it's likely a sign that it's malfunctioning. In this case, the compressor may not be able to start up and work as often as it should.

To diagnose the issue, you can safely remove the condenser and discharge it with a discharge tool. Then, test the condenser of start-up with a capacitance meter to see if it's faulty.

Here's a step-by-step guide to troubleshooting the condenser of start-up:

If you're experiencing a failure of the inverter, it's essential to identify the root cause. The inverter modulates the power supplied to the compressor, making it more efficient.

The inverter requires a specific voltage to function correctly. It needs a 120 V CA voltage from the main power supply and a 4-6 V DC voltage from the main control board. All measurements should be taken with the system connected.

A lack of either of these voltages will prevent the inverter from functioning. It's also crucial to check the compressor for continuity, as a short circuit or other issues can prevent it from working properly.

Here are the key steps to troubleshoot the inverter:

The motor refrigerador is a crucial component of your fridge, and when it doesn't start, it can be frustrating. A faulty relay of start can prevent the compressor from receiving the initial energy needed to start.

One common issue is a defective condenser, which can't provide the electrical impulse the compressor needs. If your condenser is damaged, it might be time to replace it.

A thermal protector can also be a culprit, especially if the motor overheats frequently. If it's constantly activating, it can prevent the motor from starting.

Problems with the electrical system can also cause the motor to fail. This can include a bad connection, blown fuses, or damaged cables.

If the motor is severely damaged, it may not start at all. This is a more serious issue that requires professional attention.

Here are some possible causes of a non-starting motor refrigerador:
