Search for the place where it is located fan in the refrigerator Whirlpool, is often the first step in diagnosing problems with cooling or the appearance of extraneous noise. The design of modern units of this brand, especially models with the No Frostsystem, implies a hidden location of cold air blowers, which complicates visual diagnostics without dismantling the panels. Understanding the exact location of the unit is necessary not only to replace a failed part, but also to carry out high-quality cleaning of ice jams.
In most cases, the blower is hidden behind the back wall of the freezer or in the upper part of the refrigerator compartment, if we are talking about dual-circuit systems. It is critically important before starting any work to completely de-energize the unit and wait at least 12 hours for the ice to thaw. An attempt to open an icy case without defrosting can lead to damage to the plastic fasteners and the evaporator. Let's look in detail at how to find this unit in different modifications of equipment.
Features of the Whirlpool air circulation system
Refrigerators Whirlpool equipped with a complex air flow distribution system, which ensures uniform cooling of all chambers. Unlike static cooling, here circulation fan works constantly or cyclically, driving air through the evaporator. The location of this element directly depends on the type of system: Total No Frost, combined or classic drip with additional airflow.
Brand engineers often place the fan motor in close proximity to the defrost heating elements, which creates additional risks during careless maintenance. Thermostat and temperature sensors are also located in the same technological compartment. Therefore, access to the fan requires sequential removal of several layers of insulation and plastic panels.
It is worth considering that in some models of the series Supreme or 6th Sense a double airflow system can be used. In this case, one fan serves the freezer compartment, and the second, smaller one, is located in the refrigerator compartment behind the decorative panel on the rear wall. Localizing the noise will help you understand which blower requires attention.
Localizing the fan in the freezer compartment
In models with the system No Frost the main fan is almost always located in the freezer compartment. To get to it, you need to completely empty the chamber of products, remove all shelves, drawers and guides. Visually, you will see the back wall, which is often a false panel hiding the evaporator and supercharger.
The panel fastenings can be hidden under plastic plugs or located deep in the drawer niches. After unscrewing all the screws, the panel is carefully moved to the side. Fan in this area it is usually fixed to the evaporator body or to a special platform in the upper part of the niche. It is aimed at the air duct channels that distribute the cold.
Pay attention to the condition of the door seal before starting work. If the rubber band does not fit tightly, moist air enters the chamber, which leads to ice accumulation not only on the evaporator, but also on the fan mechanism itself. In such cases, even a working motor can jam due to ice crust on the blades.
⚠️ Attention: The plastic of the internal panels becomes extremely fragile at low temperatures. Do not use excessive force when removing the fasteners so as not to break the latches.
Location in the refrigerator compartment
If your refrigerator Whirlpool is equipped with a dual cooling system, the second fan may be located in the main chamber. Most often it is hidden behind the top decorative panel (plafond) or behind the back wall if it is made in the form of a removable box. On models with a display on the door, the wiring to the fan is often routed through the door hinge, requiring special care during removal.
To access the top fan, you must remove the shelf located directly below the ceiling of the chamber. Some modifications require dismantling the lampshade, which is held in place by latches. Under it, access to the air ducts and the blower impeller opens. Defrost sensor This area can also be the cause of a malfunction if the system does not see a command to turn on the blower.
Why is the new fan humming?
If after replacing the part it appears hum, check whether the impeller touches the walls of the housing or wiring. Also, the reason may be a defective bearing or the absence of damper rubber bands on the mounting screws.
There are cases when the fan in the refrigerator compartment is integrated into a single unit with the control system Whirlpool 6th Sense. In such a situation, replacement may require resoldering the contacts or replacing the entire module, since individual components may not be supplied by service centers.
Fault symptoms and diagnostics
You can understand what fan in your refrigerator Whirlpool is in a faulty state, you can a number of characteristic features. The first and most obvious symptom is a change in the acoustic background: the appearance of a grinding sound, howling or periodic knocking. This indicates wear of the bearings or a foreign object entering the impeller.
The second sign is the lack of air circulation when the compressor is running. If the motor hums, but the cold does not spread through the chambers, the motor shaft may be jammed or the winding may have burned out. The third symptom is the formation of a “coat” of ice in one corner of the chamber while the rest of the volume is dry, which indicates a local failure in the operation of the blowing system.
☑️ Fan diagnostics
For accurate diagnostics, you can use a multimeter. By ringing the motor winding, you can determine the presence of an open circuit or short circuit. Normal resistance varies depending on the motor model, but is usually several hundred ohms. If the device shows infinity or zero, the part must be replaced.
| Symptom | Probable cause | Required action |
|---|---|---|
| Strong hum when the door is open | The door sensor is triggered, stopping fan | Checking the door limit switch |
| Crackling and grinding | Wear of bearings or ice on the blades | Defrosting or replacing the unit |
| The top does not freeze camera | Stopping the refrigerator compartment fan | Checking the motor power supply circuit |
| The fan does not start | Breakage of the winding or faulty board | Replacing the motor or module |
The process of dismantling and replacing the part
The replacement procedure begins with complete defrosting of the unit. Even if there is visually no ice, moisture inside the insulation can crystallize when the new motor is running. After defrosting, remove the back panel in the freezer. Before disconnecting the wires, be sure to remember or photograph the color coding of the terminals.
The fan itself is usually attached with 2-4 screws to the evaporator bracket. After carefully unscrewing them, remove the assembly. When installing a new part, make sure that the direction of rotation of the blades matches the markings on the housing (usually an arrow indicates the direction of air flow). Do not overtighten the mounting screws so as not to damage the plastic motor housing.
Assemble in the reverse order. Pay special attention to the laying of the wires: they should not touch the defrost heating elements or fall into the impeller rotation zone. Use heat-resistant insulation when extending wires is necessary.
⚠️ Attention: Technical characteristics of fans may vary even within the same series of refrigerators. Order the spare part strictly according to the number (P/N) indicated on the nameplate of the old engine.
Cleaning and maintenance of the blowing system
Often the problem is solved not by replacement, but by thoroughly cleaning the unit from dust and fluff that accumulate over years of operation. A dust coat on the blades disrupts the balance, causing vibration and increased noise. To clean, use a soft brush and a slightly damp cloth, avoiding getting water on the electrical contacts.
It is also recommended to check the condition of the air ducts. Small objects (candy wrappers, pieces of packaging) can get stuck in them, which, when they hit the impeller, cause a characteristic crackling sound. Blowing the channels with compressed air helps remove hard-to-reach contaminants.
Regular checks of door seals and the serviceability of the defrost sensor will help extend the life of the fan. If the defrost system is not working properly, ice builds up faster, increasing the load on the engine every time you start it. Timely maintenance will prevent expensive repairs.
Is it possible to lubricate a fan if it starts to make noise?
Most modern models Whirlpool use fans with maintenance-free plain bearings or sealed ball bearings. Trying to lubricate them with oil can lead to dissolution of the factory lubricant and accelerated wear. If noise appears, it is more effective to replace the entire assembly, since the life of such motors is limited.
Why does the fan only work when the door is open?
This is abnormal behavior. Typically, the operating algorithm Whirlpool suggests that the fan stops when the door is opened, so as not to blow cold into the room. If the motor turns on only when the door is open, the limit switch is probably faulty or the contacts were mixed up during a previous repair.
Where can I find the spare part number for the fan?
The part number (P/N) is stamped on a sticker located directly on the fan motor housing. Information can also be found in the service documentation or on the manufacturer’s website by entering the full model number of the refrigerator indicated on the nameplate inside the chamber.
