7.2 Heating Element
7.3 Inlet Control Thermistor
WARNING
· When replacing the heating element, refer to the code shown in the list of spare parts relating to the Appliance.
· It is strictly forbidden to tamper with the heating element in any way.
7.2.1 General Characteristics
For Electric Models
The Heating Element converts Electric Power into heat through the process of resistive heating. Electric current passing through the element encounters resistance, resulting in heating of the element.
In Electric Dryers, heat is generated by the heating element. The element is a coil of heating wire enclosed in a metal chamber. Electric current flowing through the coil creates heat and the air being pulled through the chamber absorbs this heat and becomes hot.
For Gas Models
The Gas models are equipped with a Gas Valve and Burner assemblies enclosed in a metal chamber. The Gas flows through the valve and is ignited which creates heat. Air is pulled through the chamber and becomes hot.
WARNING
When replacing the Inlet Control Thermistor, refer to the code shown in the list of spare parts relating to the Appliance.
7.3.1 General Characteristics
The Thermistor is a type of resistor whose resistance varies significantly with temperature.
The Thermistor measures the temperature of the air in the Dryer and adjusts the heat accordingly. When a Thermistor fails, it can cause the Dryer not to heat at all or heat up to the wrong temperature. It is used to check the temperature of air near Drum Inlet in Rear Air Duct.

WARNING
When replacing the Outlet Control Thermistor, refer to the code shown in the list of spare parts relating to the Appliance.
7.4.1 General Characteristics
A Thermistor is a type of resistor whose resistance varies significantly with temperature. The Thermistor measures the temperature of the air in the Dryer so that the Dryer knows its temperature limits. When a Thermistor fails, it can cause the Dryer to not heat at all or heat up to the wrong temperature. It is used to check the temperature of air between the blower and exhaust.

7.5 Door Switch and Drum Light
WARNING
When replacing the Door Switch and Drum Light, refer to the code shown in the list of spare parts related to the Appliance.
7.5.1 General Characteristics
The Dryer Door Switch is a push button that controls the operation of the Dryer light inside the drum. When the door is closed, drum light will be OFF and drum light will be ON when the door is opened.
The Dryer Door Switch also senses the position of the door (open or closed), thus allowing the Dryer to start its function only when the door is closed.

7.6 Single-Phase Induction Motor
WARNING
When replacing the Motor, refer to the code shown in the list of spare parts relating to the Appliance.
7.6.1 General Characteristics
A single-phase AC current is supplied to the main winding that produces a pulsating magnetic field. The pulsating field could be divided into two fields, which are rotating in opposite directions. The interaction between the fields and the current induced in the rotor bars generates opposing torque. The Motor Assembly is used to drive the Dryer Drum as well as Blower. Motor is activated from Electronic Control Board through the Door Switch. The Motor is equipped with Overload Thermal Protection Tripper. This ensures that the Motor is switched OFF if any thermal overload occurs.

7.9 High-Limit Thermostat
WARNING
When replacing the High-Limit Thermostat, refer to the code shown in the list of spare parts relating to the Appliance.
7.9.1 General Characteristics
A Thermostat is a device that is used to control a heating or cooling system so that it maintains a certain temperature or keeps the temperature within a certain range. It acts as a switch which makes the circuit open or close. If temperature goes beyond the specified range, it opens the circuit else circuit remains close.
23
Electrical Components (For Models 617, 517 and 417 Series)
Function of Hi-Limit Thermostats
Based on the vast amount of heat produced by clothes Dryers during the course of normal operation, it is important that a secondary safety option is available in case problems arise. A HiLimit Thermostat serves as a safety feature that keeps the Dryer from becoming hotter than a certain temperature. Once the temperature reaches at a certain point within the Dryer, the circuit that provides power to the heater will open. This allows the Hi-Limit Thermostat to act as a secondary safety option for the primary thermostat, and also for other components such as the Thermistor and Blower.
Hi-Limit Thermostats During Normal Operation
The standard position of the Hi-Limit Thermostat is closed, allowing current to flow to the heater without interruption. Under normal conditions, the Dryer's primary operating thermostat will cycle the heater ON and OFF to prevent temperatures from rising too high within the Dryer. The Hi-Limit Thermostat will remain unaffected through all of these cycles, since the temperature inside of the Dryer will stay lower than what is required to activate the Hi-Limit Sensors (generally 250-degrees Fahrenheit, though the exact temperature may vary).
Conditions to Activate Hi-Limit Thermostats
If the temperature within the Dryer exceeds the temperature allowed by the Hi-Limit Thermostat, the unit will activate and turn OFF the power to the Dryer's heater. There are several conditions that could lead to this increased temperature, including a fault in a part such as the Primary Operating Thermostat, Thermistor, and Blower. Other conditions that can lead to an increase in temperature are significant enough to trip the Hi-Limit Thermostat, include the improper configuration of components, such as the Primary Thermostat or heater. Blocked or clogged exhaust vents can also cause a significant increase in the temperature within the Dryer and are one of the most common causes for the activation of a Hi-Limit Thermostat.

7.10 Contact / Moisture Sensor
WARNING
When replacing the Contact / Moisture Sensor, refer to the code shown in the list of spare parts related to the Appliance.
7.10.1 General Characteristics
A "Moisture Sensor" or "Dryness Control" retards the advancing of the timer. The device uses an Electronic Control Board in conjunction with sensor strips inside the drum, which come into contact with the clothing as it tumbles. When contact is established with the wet clothing, a short is created between the two strips allowing power to flow to the Electronic Control Board which then acts upon the information allowing the timer to advance or stop.
The Moisture Sensor controls may count the number of times this short occurs over a given period and act upon that information appropriately. More `hits' means more wet clothing in the Dryer, in which case the control may delay advancing of the timer for longer, to allow more time for them to dry. In this case, less `hits' would mean fewer or not as damp clothing in the Dryer, which means advancing of the timer may not be retarded as long.

7.11 Mist Valve
WARNING
When replacing the Mist Valve, refer to the code shown in the list of spare parts relating to the Appliance.
7.11.1 General Characteristics
The Mist Valve creates a water mist which is a water spray with a droplet size of "less than 1000 microns at the minimum operation pressure of the discharge nozzle". The droplet size can be controlled by adjusting discharge pressure through a nozzle of a fixed orifice size. By creating a mist, an equal volume of water will create a larger total surface area exposed to the hot air. The larger total surface area better facilitates the transfer of heat, thus allowing more water droplets to turn to steam more quickly.

WARNING
When replacing the Igniter, Burner, Gas Valve, and Flame Sensor, refer to the code shown in the list of spare parts relating to the Appliance.
A Gas Burner is a device used to generate a flame to heat up air using a gaseous fuel. Heat is generated by burning gas with the help of Igniter and the air is being pulled through the chamber which absorbs the heat and is used to dry the wet clothes.
8.1 Igniter
8.3 Gas Valve
8.1.1 General Characteristics
An Igniter is used to ignite the gas. An Igniter is placed in the path of the flow of gas, and when the Gas Valve is open, the gas passes across the Igniter element. The Igniter is lighted that burns the gas and produces heat. This heat is used to dry the clothes inside the Dryer.

8.2 Burner
8.2.1 General Characteristics
8.3.1 General Characteristics
A Gas Valve is a device that controls and restricts the flow of gas into the burner. This is controlled by energizing the plunger inside the coils (Secondary and Booster). When the electric current is passed into the coil, the magnetic field is created. This field controls the opened or closed positions of the valve.
8.4 Flame Sensor
8.4.1 General Characteristics
A Flame Sensor is a device that detects the presence of flame due to combustion. It detects the flame by detecting Electromagnetic Radiation, Ionization, or Heat. When the Dryer operates on gas, it requires an Igniter to light the gas and create a flame to heat the air used to dry the clothes. It also requires a Flame Sensor to ensure that the flame continues to burn inside the Flame Chamber. When the Dryer no longer creates enough heat to dry the clothes, or does not ignite a flame, test the Flame Sensor. A bad Flame Sensor will not allow the Dryer to ignite and must be replaced.
