If your dryer is not providing heat properly, then there can be numerous causes behind its malfunction. It can be a faulty timer, tripped circuit, blocked vent, malfunctioning thermal fuse, etc.
No matter what, discovering these problems is the key to troubleshooting and solving them effectively. In this article, we will explore the 10 most common reasons that cause heating problems in spinners. Moreover, we will also offer actionable tips on how to diagnose and fix these issues.
10 Common Causes of Dryer Heating Problems
This article aims at providing their users with knowledge about problems, troubleshooting, and fixing the dryer. By exploring these issues and solutions, users can save their time and money efficiently. Let’s discover the 10 common causes of dryer heating problems:
- Lack of Gas for Heating
The most common problem that causes the gas dryer not to heat properly is the lack of gas. The dryer needs a sufficient amount of gas to provide the heat for drying. If there is no gas, the dryer will fail to heat the clothes.
As a result, your clothes will remain wet even after drying. Hence, keep the flow of gas in the dryer fluent. To ensure this, check for the issues of gas supply, blockage, valve issue, leakage, etc.
- Short Circuit in Wiring
Whether it is a gas dryer or an electric dryer, a short circuit in wiring can interrupt its heat supply. In the case of an electric dryer, smooth functioning wiring ensures the electricity for heating. If there is a short circuit, then the circuit breaker in the dryer might get tripped.
A circuit breaker is a component of an electric dryer. It stops the flow of the current upon short circuits or overloading of the current. While in the case of a gas dryer, the electric components help in ignition. If there is any malfunctioning in the wire, there will be no gas igniting.
- Clogged Lint Filter
A lint filter is a component of a gas dryer that filters clothes’ lint or fiber from the air. Its primary function is to keep the flow of heat smooth. It should be cleaned after regular intervals. If not it can indirectly prevent the dryer from heating.
For instance, a clogged lint screen prevents airflow from the dryer. When air is restricted from leaving the dryer, it will result in overheating. This will activate the safety mechanisms in the dryer to shut off the heating.
- Defective Timer of Dryer
Dryers have either mechanical or automatic timers for managing drying cycles. A defect in a mechanical timer or a software crash in the automatic timer will result in the malfunctioning of the dryer. These defective timers do not let the dryer move to the next or turn off the drying cycle. This will lead to running heat inside the dryer. Hence, overheating will result in activating the thermostat, which prevents the dryer from further heating.
- Blocked Venting System
A gas dryer requires a sufficient amount of fresh air to keep a smooth inflow inside. If the vents in the dryer are blocked, it will not provide enough heat. Moreover, if the air is blocked from going out, it will keep the clothes moist.
Hence, the clothes will remain damp even when there is enough heat for drying. As a result, the user thinks that the dryer is not heating even when it is providing heat properly. Hence, a blocked venting system can cause dryer malfunction.
- Tripped Thermal Fuse
Another reason that commonly results in dryers not heating is a tripped thermal fuse. As mentioned earlier, a thermal fuse is a safety feature in a dryer that activates when there is overheating in the dryer. This helps in protecting the dryer from catching fire.
However, sometimes the thermal fuse itself gets tripped. This means that it prevents the dryer from heating even when there is no overheating. In other words, there is malfunctioning in the dryer except for the blown thermal fuse.
- Malfunctioning Heating Element of Spinner
A heating element is a crucial electrical part of an electric dryer. It consists of a few coils and wires that convert electricity into heat. Therefore, for a dryer to produce enough, its heating element should be functioning effectively.
If the heating element is malfunctioning, it will produce less heat or no heat at all. The reason behind the malfunctioning of the heating element could be the natural depreciation of time. However, it may be because of the blockage of lint traps due to debris.
- A Faulty Thermostat
A thermostat is the temperature-regulating device of the dryer. It turns off or on the heating element based on high or low temperature. A faulty thermostat can cause overheating, underheating, or no heat at all.
Moreover, a faulty thermostat also disrupts the drying procedure of the dryer. For example, uneven heating could cause under-drying or extended drying of clothes. Further, a defective thermostat can cause malfunctioning in the heating element due to irregular heating.
- Defective Ignition System
A flame sensor of the ignition system of the dryer is an essential element. Its responsibility is to detect the flame in the burner. Moreover, it ensures that the gas burner is igniting smoothly while the dryer is in operation.
If the flame sensor is defective, it will not ignite the gas. Hence, there will be no heat. It can also cause other problems. For example, short cycling is due to irregular heating of the burner. Further, it can cause safety issues.
- Malfunctioning Motor
The motor inside the dryer is responsible for providing airflow. If the motor is faulty, it won’t provide sufficient airflow. This will lead to poor heat distribution. Moreover, a defective motor can indirectly prevent the heating of the dryer. As it runs the thermostat and thermistor, malfunctioning can disrupt their functioning. As a result, the dryer will be overheated, resulting in shutting mechanisms.
