Parts for Bosch HBL57M52UC/01: Latch Parts

This is the evaporator fan motor and blade assembly that circulates cold air across the evaporator and throughout the fresh food and freezer compartments for even cooling and proper temperature control.

• Draws air across the evaporator coils and distributes chilled air to all sections
• Helps prevent warm spots, frost build-up, and temperature swings
• Common failure symptoms: unusual fan noise, intermittent or no airflow, rising temperatures, or frost accumulating on the evaporator cover
• Located in the evaporator compartment; runs during cooling cycles

• Disconnect power before servicing; wear cut-resistant gloves
• Access is typically from the rear of the freezer/evaporator cover; remove shelves and panels as needed
• Note wire orientation and mounting before removal; transfer grommets/brackets if applicable
• After installation, verify unobstructed fan spin and restore power to test operation

This temperature limiter is a safety thermostat that opens the circuit if the appliance overheats, protecting the heating system from damage. Replacing a failed limiter helps restore safe operation and consistent heating performance.

• Provides over-temperature protection by opening the electrical path at a calibrated limit
• Helps prevent overheating that can damage elements, wiring, or controls
• Common symptoms of a bad limiter: no heat, intermittent/weak heat, or cycles that stop early

• Disconnect power and allow the appliance to cool before servicing
• Note wire positions and transfer wires one at a time to the new limiter
• Reinstall in the original mounting location with firm, flush thermal contact
• Inspect and replace any heat-damaged connectors or wiring as needed

This Terminal Box is an OEM part for Bosch Built-In Ovens. Integral to the oven's electrical system, this component serves as a secure connection point for various electrical wires within the appliance.

A common issue with a malfunctioning Terminal Box is loose connections or damage to the terminal block due to heat exposure or aging. 

Symptoms of a defective Terminal Box may include:

• Inconsistent power supply to the oven
• Non-functional heating elements
• Sparks or electrical arcing within the terminal box area

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

This is a programmed electronic control module that replaces a failed main control board and restores electronic control of appliance cycles and user inputs. Ships programmed to the factory configuration for a straightforward replacement. What it does:

• Manages cycle timing, user commands and electronic control signals for the appliance
• Interprets button/display inputs and activates relays/components accordingly
• Restores normal cycle advancement when a faulty control board causes stoppage or unresponsive controls
• Can address error codes or faults tied to a failed control module

• Disconnect power to the appliance before beginning any service.
• Document wiring and connector locations (or photograph) to ensure correct reassembly.
• Handle the board by its edges and use anti-static precautions to avoid ESD damage.
• Part ships programmed; follow the OEM service manual for any final setup, calibration, or verification steps.

This spacer sets the correct gap between mating components so the assembly aligns and operates smoothly. Replacing a worn or missing spacer restores proper fit, helps prevent rubbing, and supports consistent performance. What it does:

• Maintains specified clearance and alignment within the assembly
• Helps prevent metal-to-metal contact that can cause noise or wear
• Supports smooth movement or secure mounting where designed
• Symptoms of a failed spacer can include looseness, misalignment, scraping noises, or uneven movement

• 1 spacer

• Disconnect power (and shut off gas/water if applicable) before servicing
• Access the relevant assembly and note the spacer's orientation/position
• Replace one-for-one; seat fully and avoid overtightening fasteners
• Reassemble and test for proper alignment and smooth operation

This temperature limiter is a safety thermostat that monitors heat and opens the circuit when temperatures exceed safe limits. It helps protect internal components by preventing overheating and unintended damage during operation. What it does:

• Monitors appliance temperature and interrupts power to the heater if excessive heat is detected
• Helps prevent overheating-related damage and safety hazards
• Common failure signs include no heat, intermittent heat, or the unit shutting off prematurely
• Tests open for continuity when tripped or failed

• 1 temperature limiter

• Disconnect power at the breaker and allow the appliance to cool completely
• Note wire locations and transfer one lead at a time to the new limiter
• Reinstall in the original position so the sensor makes proper contact as designed
• Inspect/replace any heat-damaged terminals; test operation after reassembly

The Door Latch is an OEM part for Bosch wall ovens and ranges. It secures the oven door safely closed during baking and broiling. As an essential component for safety, the latch allows controlled access to the cooking cavity while preventing accidental openings.

Causes can be wear from constant use, damage from impact, or deterioration of latch parts over time.

Symptoms of a faulty latch include:

• The door popping or swinging open during use
• Difficulty closing or fully engaging the latch mechanism
• Looseness around the door seal compromising heat retention

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