If you’re dealing with this problem, don’t worry; there are several easy ways to fix it. This article will cover the common reasons behind an LG dryer not turning off and provide five easy ways to resolve the issue.
Why Won’t Your LG Dryer Turn Off?
Before attempting to fix the issue of your electric dryer not turning off, it’s important to first consider the possible sources of the problem to help in the dryer troubleshooting. Let’s dive into the 5 most common reasons an LG dryer may not turn off as intended.
Malfunctioning Timer
When an LG dryer’s timer mechanism malfunctions, it can prevent the machine from turning off at the end of the cycle as intended. The timer is responsible for keeping track of the duration of the drying cycle and triggering the machine to shut off once the set time has elapsed.
If the timer is not functioning correctly, it may not accurately measure the duration of the cycle, leading to the dryer continuing to run beyond the intended time. This malfunction can occur due to various reasons, such as wear and tear, electrical problems, or damage to the internal components of the timer.
For example, if the dryer motor or gear timer become damaged, they may be unable to keep accurate time. They may also get stuck in one position, causing the dryer to keep running even after completing the cycle.
Furthermore, exposure to high temperatures or moisture can affect the timer’s accuracy and functionality. This is because extreme temperatures can cause the internal components of the timer to expand or contract, leading to misalignments and malfunctions.
Stuck Relay Switch
A stuck relay switch is another potential reason an LG dryer may not turn off. A relay switch is an electrical component that allows an electrical signal to control a different circuit.
In a dryer, the relay switch is responsible for turning the machine on and off in response to signals from the timer or control board.
When a relay switch becomes stuck, it can cause the dryer to continue running even after the cycle has completed. This happens because the switch does not respond to the signals it receives to turn off the machine.
There are various reasons why a relay switch can become stuck. One possibility is that the contacts inside the switch have fused together due to high electrical currents. This can cause the switch to remain in the “on” position, even when it should be “off”.
Alternatively, the switch may have become stuck due to physical damage or a build-up of dirt or debris. Regardless of the cause, a stuck relay switch can cause the dryer to run continuously, leading to increased energy consumption, potential overheating, and even a risk of fire.
It is crucial to address this issue promptly to avoid further damage to the machine and to ensure safe operation.
Faulty Control Board
The control board is the component that governs the dryer functions, including controlling the timing of the drying cycle and monitoring the temperature inside the drum. If the control board is faulty or damaged, it can prevent the dryer from shutting off properly at the end of the cycle.
There are several reasons why the control board may malfunction. One possibility is that it has been damaged due to exposure to moisture or high temperatures. Over time, this exposure can cause the board’s components to degrade or become damaged, leading to malfunctions.
Another potential cause of a faulty control board is an electrical power outage. These events can cause damage to the delicate electronic components of the board, leading to malfunctions and failures.
In addition, wear and tear over time can cause the control board to malfunction. This is particularly true for older dryers, whose components may be more prone to degradation and damage.
Broken Thermostat
A broken thermostat is another potential reason an LG dryer may not turn off. The thermostat is a component that is responsible for monitoring the temperature inside the drum and signaling the machine to shut off when it reaches a certain level.
If the thermostat is broken or malfunctioning, it may be unable to accurately detect the temperature and signal the machine to turn off when the cycle is complete.
There are a variety of reasons why a thermostat may fail or malfunction, and it’s crucial to identify and address the issue quickly to ensure the safe and efficient operation of your LG dryer. One possible reason is exposure to high temperatures or moisture, which can damage or degrade the components of the thermostat, leading to malfunctions.
Another factor to consider is wear and tear over time, especially for older dryers, where the components may be more susceptible to degradation and damage. Moreover, a faulty sensor or wiring can cause the thermostat to inaccurately detect the temperature inside the dryer drum, leading to a broken thermostat.
No matter what the cause, a malfunctioning thermostat can result in the LG dryer continuing to run beyond the cycle, leading to overheating and even the risk of fire.
Clogged Vent
A clogged vent is another potential reason why an LG dryer may not turn off. During the drying cycle, the vent expels hot air and moisture from the dryer drum.
If the vent becomes clogged with lint or other debris, it can prevent the hot air from being properly expelled, which can cause the machine to continue running beyond the end of the cycle.
A vent blockage can be a real headache, and there are several reasons why it might happen. One common culprit is neglecting to clean the lint trap, allowing lint and debris to accumulate in the vent over time.
Another possibility is that the vent hose has become damaged or twisted, obstructing the proper expulsion of hot air from the machine. Sometimes, external factors like debris build-up can also clog the vent system, especially in multi-story or twisting homes where blockages are more likely to occur.
No matter the root cause, it’s essential to act fast and address the issue immediately to ensure your dryer’s safe and efficient operation.
