Major Parts of the Kenmore 90 Series Dryer
1. Drum and Drum Support Components
The drum is the central component responsible for tumbling clothes during drying. Proper support and rotation are maintained through several parts:
- Dryer Drum: Usually made of steel with a smooth surface, it holds and tumbles clothes.
- Drum Bearings: Support the drum's rotation, typically located at the rear or front of the drum.
- Roller Supports and Rollers: Help the drum rotate smoothly; worn rollers can cause noise or uneven drying.
- Drum Glides: Located at the front of the drum, these help the drum glide smoothly during rotation.
2. Heating Elements and Thermostats
Heating components are vital for generating the hot air needed for drying:
- Heating Element: Converts electrical energy into heat; common failure causes insufficient heat.
- High-Limit Thermostat: Prevents overheating by shutting off the heat if temperatures exceed safe limits.
- Thermostats (Regulating Thermostats): Maintain consistent temperature levels within the dryer.
- Thermistor or Temperature Sensor: Monitors the temperature inside the drum to regulate heating cycles accurately.
3. Belts and Pulleys
The drive belt transmits power from the motor to turn the drum:
- Drive Belt: Usually made of rubber with a reinforced cord, it is critical for drum rotation.
- Idler Pulley: Maintains tension on the belt, ensuring smooth operation.
- Drive Motor Pulley: Connects the motor shaft to the belt.
Worn or broken belts can result in the drum not turning or making loud noises.
4. Motors and Rotational Mechanisms
The motor powers the drum and, in some models, the blower:
- Drive Motor: Responsible for rotating the drum.
- Blower Motor: Circulates air through the dryer and out the vent.
- Motor Coupling: Connects the motor to other components; failure can cause the motor to run but the drum not to turn.
5. Venting and Exhaust Parts
Proper airflow is essential for efficient drying:
- Venting Ducts: Channel moist air outside.
- Lint Filter and Lint Screen: Capture lint and debris, preventing blockages.
- Exhaust Fan: Assists in venting hot, moist air out.
- Venting Damper: Opens during operation to allow airflow and closes when off to prevent backdrafts.
Clogged vents or damaged dampers reduce efficiency and can cause overheating.
6. Control Boards, Switches, and User Interface
The electronic control system manages the dryer's operation:
- Control Board (Main Control Module): Processes user inputs and sensor data to control functions.
- Start Switch and Cycle Selector: Allow user to select drying cycles.
- Door Switch: Ensures safety by disabling the dryer when door is open.
- Timer and Cycle Indicators: Show remaining drying time and cycle status.
Malfunctioning control parts can lead to cycle interruptions or failure to start.
7. Safety and Auxiliary Components
Additional parts that enhance safety and functionality include:
- Thermal Fuse: A safety device that cuts power if overheating occurs.
- Pressure Switch: Detects airflow restrictions and stops the cycle if necessary.
- Moisture Sensors: Detect moisture levels and optimize drying time.
- Lint Trap: Essential for safety and efficiency, trapping lint before it reaches the vent.
Common Issues and Corresponding Parts in the Kenmore 90 Series Dryer
Understanding common problems can help you identify the right parts for repairs:
- Dryer Not Heating: Likely caused by a faulty heating element, thermostat, or thermal fuse.
- Drum Not Turning: Usually due to a broken belt, failed motor, or defective rollers.
- Noisy Operation: Worn rollers, drum glides, or belt misalignment.
- Takes Too Long to Dry: Clogged vent, malfunctioning moisture sensors, or weak heating elements.
- Dryer Won't Start: Faulty door switch, control board, or start switch.
Identifying the correct part to replace requires understanding which component has failed.
