Parts for Bosch WTMC3300US/01: Heater And Motor Assemblies Parts

The Screw is an OEM part for Bosch microwave ovens. It is a component that secures the outer casing and front paneling of the microwave. The screw is designed to withstand repeated heating and cooling cycles without loosening or degrading. 

Symptoms of bad screw include:

- The front panel or outer casing becoming loose, detached, or misaligned
- Gaps appearing in the seams or joints of the microwave structure
- The door not sealing properly leading to leaks

Over many uses of the microwave, screws can wear down or strip out from over-tightening during repairs or installations. It is important to replace worn screws to ensure the microwave maintains an intact structure.

This OEM Bosch part is also compatible with Thermador, Gaggenau, and some Kenmore models.
 

The Temperature Limiter is an OEM component specifically designed for select Bosch vented dryers requiring controlled airflow temperatures. As a safety device, it restricts exhaust heat to prevent overheating risks.  

Precisely calibrated links of heat-treated alloys automatically trip circuits upon exceeding preset thermal thresholds. Protected housings shield reactive cores from moisture while allowing intended response capabilities.

Causes often involve years of exposure distorting sensitive triggering components slow to cool cycles. Intentional physical manipulation could also disable protection absent automatic overrides.

Symptoms of a bad temperature limiter include:

• Inability to sense and respond to rising exhaust air temperatures  
• Lack of functioning cool-down phases from disabled safety trips
• Continuously energized heating systems without regulation posing risks

This OEM Bosch replacement limiter is also compatible with Thermador, Gaggenau and select Kenmore dryers employing sensitive temperature cutoffs. Correct installation restores critical safety control circuits.
 

The Motor is an OEM component specifically designed for select Bosch electric dryers. Powering the tumbling drum, its precisely balanced construction generates consistent motion. Permanent lubrication withstands thousands of cycles.

Causes of a faulty motor commonly involve winding failure and diminishing torque output. Overheating causes internal damage necessitating replacement before hazards arise.

Symptoms of a bad motor include:

• Slow or incomplete tumbling resulting in damp loads  
• Grinding noises during operation
• Chronic imbalances necessitating resets 

Causes of a bad motor can relate to typical degradation reducing efficiency. Prolonged high-heat exposures weaken insulation requiring timely replacement. 

This OEM Bosch part is also compatible with some Miele and Asko dryers. Replace to retain smooth controlled drying for fluffy fully-ventilated fabrics long-term.
 

This fan wheel circulates air through the appliance to support drying and cooling cycles, restoring proper airflow and temperature regulation. Replaces a worn or damaged blower impeller to improve performance and reduce overheating risk. What it does:

• Spins to draw and push air through the appliance's vent and heating chamber.
• Restores airflow when a cracked or warped wheel causes weak drying or poor ventilation.
• Can reduce unusual rattling or grinding noises caused by broken blades or imbalanced rotation.
• Helps prevent overheating by maintaining designed air movement.

• One fan wheel

• Disconnect power (and gas supply, if applicable) before beginning service.
• Access the blower housing; confirm orientation and fit before final assembly.
• Inspect surrounding seals and fasteners; replace any damaged clips or screws to ensure secure mounting.
• If you hear continued noise or airflow problems after install, re-check wheel clearance and shaft/bearing condition.
