Refrigerator motor makes noise but doesn't work

A refrigerator cannot perform its functions without a well-functioning motor. Although motors are known to last for a long time, they may break down after a short period of time. This has led many to search for the reasons why the refrigerator motor makes noise and does not work, as it is the most common problem. There are many reasons that may cause this motor malfunction, which certainly differ from one person to another. We will mention these reasons below.

Reasons for a refrigerator motor to make noise when not working

Many people may be surprised by an unusually loud noise coming from their refrigerator. This noise indicates a problem with the refrigerator motor, which can be caused by a number of factors, including:

1. Low source voltage

A refrigerator compressor needs a certain voltage to reach it. When this voltage drops, the problem begins. It cannot rotate, and is forced to draw high amperages, which causes the temperature of the compressor motor coils to rise, resulting in a whirring sound.

2. Increase in heat load

Any increase in the electricity source, which affects the refrigerator motor, and this has a number of reasons, such as:

Place the refrigerator in a place exposed to direct sunlight.
Or place the refrigerator next to the oven, stove, or heater.
Or if the refrigerator is located in a poorly ventilated area, all of this is considered an additional thermal load on the refrigerator, which affects the compressor.

When the compressor starts to rotate, the thermal protection circuit breaker trips because the circuit breaker temperature is high. The solution to the problem lies in checking the temperature of the air surrounding the refrigerator, as well as the internal thermal loads in the cabin.

3. There is a problem with the relay.

The relay is one of the electrical components inside the refrigerator. Its function is to connect and then disconnect the starter coils, allowing the motor to start operating via the starter coils. If the relay coil is exposed to a problem or insulating materials accumulate on the contact points, a buzzing sound is emitted from the motor.

4. Seizure of the internal part of the refrigerator motor.

This often happens when the compressor becomes too hot, which heats up the mechanical parts inside the compressor.

5. Damage to the motor starter coils.

The refrigerator motor has starter and starter coils. The starter coils operate until the compressor reaches 75% of its speed. After that, these coils are removed from the circuit, and the refrigerator motor begins to operate based on the starter coils. If there is a failure in the starter coils, the motor will make a loud noise and shut down.

6. Calendar files are exposed to interruption.

The refrigerator motor relies heavily on the starter coils to operate. A break in these coils means the motor is unable to start, which results in a high amperage draw and a rattling sound from the refrigerator motor.

What is the evidence that the refrigerator motor is burned out?

There are some signs that you may notice that will indicate that your refrigerator motor has burned out and needs to be replaced, including the following:

The engine is running very loudly.
Compressor lock.
The connection pins are damaged.
Compressor motor coils are damaged.
The internal protection circuit breaker is damaged.

Why can't I hear the refrigerator motor sound?

There are two cases when you cannot hear the refrigerator motor sound:

1. The first (normal) case

In this case, the refrigerator motor noise is not allowed while the refrigerator continues to cool normally. Here, the compressor type is designed to be noiseless during operation.

Or if the compressor sound is heard for a while, then stops, then comes back again, this also rules out the possibility of a problem, as the refrigerator motor does not operate continuously and stops once it reaches a certain temperature.

2. The second case (abnormal)

This condition indicates a malfunction in which the refrigerator is not cooling and no motor noise is allowed.

Why is the refrigerator light off?

Refrigerators are designed with an internal light that lights up as soon as you open the refrigerator. This allows us to clearly see the food and drinks inside. If the refrigerator light goes out and stops working, it is often due to the following:

The cabin lamp is damaged.
The bulb holder is damaged.
Damaged or malfunctioning lamp switch.
A cut in one of the wires.

Why does the refrigerator not cool and the freezer not freeze?

Your refrigerator may not be cooling and your freezer may not be freezing for any of the following reasons:

No electricity reaching the refrigerator, or the electrical cable is cut.
The condenser is not performing its cooling function well.
Thermostat fault.
The capacitor is damaged.
The electrical connections to the compressor are not tight.
Compressor coils damaged.
Freon gas leak.

A clicking noise in the refrigerator motor

The motor, also known as the compressor, consists of a set of mechanical components. When it makes a clicking sound while the refrigerator isn't operating efficiently, this indicates a problem with it. The best solution is to replace it, as it is a closed type and therefore difficult to repair.

The refrigerator motor is making a loud noise.

The refrigerator motor makes a loud noise in these cases:

The refrigerator is out of balance.
The water collection bowl above the compressor is subjected to severe vibration.
Condenser tubes touching the refrigerator body.
Some parts of the electrical system are subject to vibration.
Loosen the mounting screws.
There is a problem with the internal springs of the compressor suspension.
Air entering the cooling cycle.

The refrigerator motor is not working.

The most common reasons why a refrigerator motor doesn't work are:

There is damage to the electrical wiring.
The voltage supplied to the motor is significantly reduced.
The refrigerator thermostat is damaged.
External overload is damaged
Damage or malfunction of the electronic control board.
Capacitor damage.

humming noise in refrigerator

A sound may come from the refrigerator, which many describe as a buzzing sound. This can be caused by a number of reasons, including:

Air pressure changes: Frequently opening and closing the refrigerator causes changes in the air pressure inside it, which results in a squeaking sound when the doors are moved.
Close tightly: Closed refrigerator doors may cause a hissing sound when opened due to air pressure.
Expansion and contraction: The materials used in the refrigerator may expand and contract as the temperature changes, which can cause a sizzling sound.
Refrigerator needs maintenance: This noise may be due to the refrigerator needing maintenance, such as lubrication of the seals or the need to replace one of the internal parts.
Accumulation of ice inside the refrigerator

refrigerator motor price

When a refrigerator motor is damaged, it must be replaced immediately. That's why people ask, "How much does a refrigerator motor cost?"

The price of a refrigerator motor varies depending on several factors, including:

Refrigerator type
The producing company
Where to buy from
Motor quality and efficiency

If your refrigerator motor is making noise but not working, you have every reason to know the seriousness of the problem and how to solve it. The safest and best solution remains replacing the refrigerator motor and following methods that will preserve it for the longest possible period, which you can obtain by consulting a specialist.
