Checking the Thermal Fuse
To ensure the safety of your appliance, it is crucial to have a functional thermal fuse. This component prevents any heat-related damage or injury-causing incidents, making it a crucial part of any appliance that generates heat. To check the thermal fuse of your dryer, use an electrical multimeter that can measure resistance in ohms. First, set the dial of the meter to the ohms measure. Then, touch one of the meter’s leads to one of the fuse’s terminals, and the other lead to the other terminal. A zero ohm reading on the meter display indicates that the thermal fuse is functional and does not require replacement. However, if the reading shows significant or infinite ohms, the fuse has blown and needs replacement. Typically, the thermal fuse of a dryer is located on the exhaust duct of the appliance. If it has blown, the dryer will not function, and you will need to purchase a replacement fuse specific to your dryer’s model. Resetting the blown fuse is not an option.Top of Form
Examining the Functioning Thermostat
The cycling thermostat is responsible for regulating the temperature of the dryer’s heating element. It cycles the element on and off to maintain a consistent temperature. If it malfunctions, the cycle may stay open and the dryer will not produce heat.
A faulty cycling thermostat can cause your dryer to overheat or blow thermal fuses. You can check it with a multimeter by connecting the red and black probes to the thermostat’s terminals.
If the reading is not zero, you will need to replace the thermostat. The thermal fuse is a safety device that cannot be reset, and it will break the electrical connection to the dryer’s burner if the temperature exceeds safe levels. This can be caused by a clogged dryer duct or a defective cycling thermostat.
Testing the Flame Sensor
If your gas dryer is not producing heat, it might be because of a defective flame sensor, which would need to be replaced. Usually, the flame sensor is a small black box located outside the flame igniter and beneath the dryer drum. Its function is to detect the presence of a flame, and if it does not detect one, it shuts down the gas valve. Using a multimeter, you can check if the flame sensor is functioning correctly, which will help you determine if it is the root cause of the problem or if there is another faulty component. You will need to remove the screw that holds the sensor in place and carefully detach it, after which you can use a multimeter to test the resistance between the white and blue wire ports that are present on the flame sensor.
Verifying the Function of the Gas Valve Coils
The gas valve of a dryer plays a crucial role in the functioning of the burner assembly. It regulates the flow of gas to the burner by opening when the unit is turned on and closing when the appliance is turned off. The solenoid coils, which are an integral component of the gas valve, are responsible for opening and closing the gas valve. If the coils are malfunctioning, the gas valve will not open correctly and the dryer will not generate heat. These coils are powered by electricity that passes through them to activate an actuator, which then opens a passageway for gas to flow from the coil to the gas valve. You can easily identify faulty gas valve coils by listening for a clicking or clunking sound as the valve tries to activate. Additionally, you may notice that the igniter glows a bright orange color when the gas valve attempts to open. The coils can be found either inside the gas valve or near the top of the burner assembly, depending on the dryer model. Replacing the coils is usually a straightforward process that requires only basic tools such as a screwdriver.
Verifying the Functionality of the Igniter
If your dryer is running, but not producing any heat, the issue could be with the Igniter. The Igniter can be found in close proximity to the gas valve burner tube and is responsible for lighting the gas that is released by the valve. Newer gas dryers usually include a radiant sensor that senses the heat from the igniter to activate the gas valve and maintain the flame in the burner assembly. A malfunctioning sensor will cause the igniter to stop glowing, or the gas valve to remain closed. Another possible culprit is the dryer’s cycling thermostat. You can check this by connecting one probe of a multimeter to each of the thermostat’s terminals. If the reading is zero or infinity, you will need to replace the cycling thermostat. If the reading is something else, the igniter may be defective or the thermistor may have lost continuity.
