Key Components of the Kenmore 700 Series Dryer
The main parts of a Kenmore 700 Series dryer can be categorized into several groups based on their function: the drying mechanism, airflow system, electrical components, and user interface. Below is a detailed examination of each category.
1. Drum and Drum Support Components
The drum is the central component that holds clothes during the drying cycle. It is supported and rotated by several parts:
- Drum: Usually made of steel or aluminized steel, the drum is the primary container for clothes.
- Drum Rollers: Support the drum and allow it to rotate smoothly. They are located at the rear and sometimes at the front.
- Rear Drum Bearing: Supports the rear of the drum and helps reduce friction.
- Front Drum Bearing or Support Roller: Supports the front of the drum and allows smooth rotation.
- Glides or Slides: Help the drum rotate smoothly and prevent metal-on-metal contact.
Common issues include worn drum rollers, broken glides, or damaged bearings, leading to noisy operation or drum misalignment.
2. Heating Elements and Thermostats
The heating system is vital for drying clothes efficiently:
- Heating Element: Responsible for generating heat to dry clothes. It’s typically a coil that heats up when electricity flows through it.
- Thermostats: Regulate temperature within the dryer to prevent overheating.
- High-limit Thermostat: Cuts power to the heating element if the temperature exceeds safe limits.
- Cycling Thermostat: Maintains the temperature within the desired range during operation.
- Thermistor or Temperature Sensor: Provides feedback to the control board about the air temperature inside the drum.
Malfunctions in these parts can cause the dryer to run without heat or shut off prematurely.
3. Blower Wheel and Fan
Proper airflow is essential for effective drying:
- Blower Wheel: Circulates air through the heating element and the drum.
- Blower Motor: Powers the blower wheel.
- Air Ducts and Venting: Channels moist air out of the dryer and reduces lint buildup.
Problems such as a broken blower wheel or a defective blower motor can lead to poor airflow, longer drying times, or overheating.
4. Electrical Components and Controls
These parts manage the operation and safety features of the dryer:
- Control Panel and Timer: Allows users to select drying cycles and options.
- Motor: Rotates the drum; it also powers the blower wheel.
- Start Switch and Door Switch: Enable operation when the door is closed and the start button is pressed.
- Fuses and Thermal Cut-Offs: Protect the dryer from electrical faults or overheating.
- Circuit Board (Control Board): Coordinates the operation of various components based on cycle settings.
Electrical issues can cause the dryer to not start or cycle improperly.
5. Lint Filter and Vent System
Efficient lint removal and venting are critical:
- Lint Filter: Catches lint and debris to prevent buildup in the venting system.
- Venting Ducts: Exhaust moist air outside; must be clear for optimal airflow.
- Lint Trap Housing: Holds the lint filter securely in place.
Clogged or damaged filters and vents can cause overheating or reduce drying efficiency.
