If you’ve ever opened your refrigerator late at night only to be greeted by a flickering light, you’re not alone. Flickering fridge lights is a common issue, but luckily, there are several troubleshooting steps you can take to fix the problem.
In this comprehensive guide, we will explore the causes of flickering fridge lights and provide you with step-by-step solutions to resolve the issue. So, how do you fix a flickering fridge light?
Causes of Flickering Fridge Lights
There are several potential causes for flickering fridge lights. Understanding these causes will help you pinpoint the issue and find an appropriate solution. Here are some common reasons why fridge lights may flicker:
Loose or Worn-Out Bulb
One of the most common causes of flickering fridge lights is a loose or worn-out bulb. If the bulb is not securely screwed into the socket, it may not receive a constant power supply, resulting in flickering.
Similarly, old bulbs may start to flicker as they near the end of their lifespan. Checking and tightening or replacing the bulb can often resolve this issue.
Overheated LED-Array Controller
In modern fridges, LED lights are commonly used. These lights are controlled by an LED-array controller, which can overheat and cause flickering if there are loose wiring connections or poor circuitry.
Overheating can be a result of poor ventilation or other internal issues. In such cases, it may be necessary to examine the LED-array controller and repair or replace it if necessary.
LED Bulbs in Incandescent Bulb Housings Don’t Match Dimmer Wattage
Some fridges may have LED bulbs installed in incandescent bulb housings. If the LED bulbs have a different wattage than what the dimmer switch is designed for, flickering may occur.
It is important to ensure that the LED bulbs used in the fridge are compatible with the dimmer switch’s electrical range to avoid flickering.
Faulty Dimmer Switch
The dimmer switch inside the fridge can also be a source of flickering lights. Over time, the dimmer switch may become worn out, damaged, or obstructed by dust or debris. Loose or broken connections can also cause flashing lights. In such cases, inspecting and potentially replacing the dimmer switch may be necessary.
Other Possible Causes
In addition to the above-mentioned causes, there are other factors that can contribute to flickering fridge lights. Inadequate power supply, fluctuating voltages, issues with internal wiring, loose cords, or internal damage can all lead to flickering. Identifying the specific cause requires careful inspection and troubleshooting.
