Suppose you open your fridge for a midnight snack but notice the light flickering. How do you behave? It is a typical problem with Whirlpool refrigerators. So don’t freak out.
What causes refrigerator lights to flicker, and what can you do? There may be no need to contact a skilled repairer. Let’s examine everything you require to resolve this problem.
Why Are My Whirlpool Refrigerator Lights Flickering?
There could be a number of causes for the flashing LED lights on your Whirlpool refrigerator. Here are some of them.
1. The Bulb Is Loose or Going Out
Flickering lights inside a fridge are often caused by loose or old bulbs. The bulb will also flicker or flash if it is loose since it won’t receive continuouas electricity. Depending on the quantity of energy it gets, the flashing can vary.
2. Overheated LED-Array Controller
A refrigerator’s circuit board is its control panel. It controls various features like lighting, cooling, and displays. Due to poor electrical connections, the LED controller’s parts can occasionally overheat and short-circuit.
In this case, you’ll need an expert technician to access the controller’s wiring to identify the issue. The service technician will try to fix it. But you’ll probably require a replacement.
3. Improper Installation of Water Filter
The incorrect installation of the water filter is one of the reasons why your bulb flicker. To resolve the issue, turn off your refrigerator. Check if the water filter is installed correctly.
Fix it yourself or ask a professional for assistance if there is an issue.
4. The Dimmer Switch is Faulty
A broken dimmer switch inside your Whirlpool refrigerator could also cause flickering lights.
A refrigerator’s internal dimmer switch may deteriorate with time or suffer damage. Problems could also arise if dust or other debris blocks the dimmer switch. Flashing lights when you open the refrigerator might occasionally be caused by dimmer connections that are loose or faulty.
5. Inadequate Power Supply
An unstable energy source is another factor which causes the flashing interior light on your Whirlpool refrigerator. The refrigerator will struggle to keep your food cool and illuminate the bulbs when less current flows into it. Ultimately, the light will blink or flash, making it challenging to see what is inside the refrigerator.
Low current entering the home or loose wiring connections cause insufficient power supply.
6. Variable Voltage
If you observe light flickering when you turn on the refrigerator, it is because it is a large electronic appliance that needs considerable voltage to start functioning. As soon as it starts, the light works correctly.
Thus this shouldn’t be a cause for concern. But, if it persists even after the door has been closed, you need to identify the underlying reason. Calling your technician can be a good idea to find the issue.
7. Problem with The Wiring Connection
Any electrical appliance needs a consistent power source to run without any problems. But it is sometimes not possible due to a bad wiring connection. It may also be the case with your whirlpool refrigerator bulb.
The loose cable attachment may impede the quantity of current that reaches the bulb. For instance, if the wiring between the switch and the lightbulb is slack, the lightbulb won’t receive enough electricity. Another possibility is that a faulty wire connection from the main supply brings on all these issues.
It’s dangerous to allow your refrigerator to operate in such a situation. So you should call an electrician to take care of this. As electrical wires can start a fire, let the professional examine the circuit breaker and fix the connection as necessary.
How to Fix the Whirlpool Refrigerator Lights Flickering?
Even something as minor as flashing LED lights on your fridge can be an unpleasant experience. Flipping a light bulb may solve the problem. But sometime it may indicate severe problems with the power source.
Here are some fixing methods you can try to solve the problem.
1. Check or Replace the Bulb
Check the bulb first. You can fix the problem if it is loose by unscrewing and reinserting the bulb.
This step is essential to avoid wasting time searching for an issue that isn’t present. If this doesn’t help, try the approaches listed below.
2. Check The Power Supply
If more than one light bulb is flickering, there can be a problem with the power source. Check the connections and power supply for any damage. Also check to see if the outlet is functioning correctly.
3. Check The Light Assembly
Your refrigerator’s light switch assembly could be to blame for the flashing lights. Follow the steps below to fix the problem:
- Check the water filter’s installation first to ensure it’s done correctly. The back of your refrigerator has a metal panel with holes. The water filter is perfectly placed if a wire can be seen poking out of one of these holes.
- Next, check the light switch assembly for any apparent damage or problems. For instance, you might observe issues with its connections to the appliance’s other components, such as the water line or power cord.
- Finally, recheck the light bulb and light socket. The light socket might need to be cleaned or repaired if it is damaged.
Depending on the Whirlpool model, you can have multiple light assemblies.
4. Look for General Issues
LED lights in a Whirlpool refrigerator may flicker due to a few common problems. The following are some of them:
- Wires or screws in the light fixture are loose
- Circuit board switches are broken
- The circuit board has poor capacitors
Use a voltmeter to check if there is power in each component of the circuit. You may need a new fuse box or switch if there isn’t one.
As an alternative, try disconnecting every lead from your appliance. After some time, you can plug everything back in to check if the problem has been fixed. This technique resets damaged capacitors. But if it doesn’t work, you could require professional help.
5. Try General Maintenance Tips
To solve the problem, you can also follow some standard maintenance tips. These suggestions will also stop the lights from flickering in the future.
- Make sure the location of your refrigerator is well-ventilated. LED lights can overheat or flicker if there isn’t adequate ventilation to keep the air moving.
- The coils on the rear of the refrigerator should be cleaned frequently. Over time, dust, debris, and grit can build up. It will overheat the coils and cause the lights to flicker.
- Make sure your LED lights have the correct wattage. Depending on your model, you might need bulbs with higher or lower wattage. Choosing the optimum lighting allows you to avoid flickering as the power levels are correct.
- Check the door’s seals to ensure they are clean, tight, and secure.
- Take out anything obstructing the vents.
- Use the temperature settings and other recommendations provided by Whirlpool. The lights can malfunction or flicker while using too-cold temperatures.
6. Call A Professional
If none of the troubleshooting techniques fixes your problem, you should contact a professional.
A certified technician familiar with Whirlpool appliances or a general appliance repair professional may be needed. The best course of action is to phone around and obtain many estimates because service costs can vary.
Occasionally, if the problem is with the power supply, a socket, or a fuse box, you might need to hire an electrician.
Your Whirlpool refrigerator’s inside lights are essential when taking out or placing different food items. But if the lights are constantly flashing, it will impair your vision and is a sign of a deeper issue.
The refrigerator’s bulbs must be examined to see if they are in excellent condition before moving on to the next phase. If the lights work, check whether the switch is defective or damaged and fix it accordingly. Determine the underlying problem and replace the components causing your refrigerator’s interior flashing, whether it’s a bad electrical connection or insufficient power supply.
