Mer57550ab Parts

This door switch detects when the appliance door is closed and signals the control so the unit can start or run. Replacing a faulty switch restores proper door-sensing and safe operation. What it does:

• Detects door open/closed status and sends the signal to the appliance control
• Prevents the unit from starting or running if the door is open
• Commonly linked to symptoms like the appliance not starting, not completing cycles, or lights/controls behaving incorrectly
• Works as the safety interlock for door-dependent functions

• One door switch

• Disconnect power before servicing to avoid shock or injury
• Match connector style and mounting alignment to the original switch before final installation
• Handle the switch and wiring gently to avoid damage to terminals or harnesses

This small rubber bumper cushions and stabilizes moving appliance parts to reduce vibration, noise and wear. It restores proper spacing where a worn or missing stop lets components rub or rattle. What it does:

• Acts as a soft stop to prevent metal-on-metal contact and dampen vibration
• Helps eliminate rattling or scraping noises from doors, drawers or panels
• Maintains correct alignment and spacing of moving parts
• Protects finishes and extends service life of mating components

• Typically pressed or snapped into a socket or mounting post; no special tools usually required
• Clean the mounting area of dirt and residue before installing for best adhesion/fit
• Ensure the bumper is the correct match and fully seated before operating the appliance
• Disconnect power when working near electrical or moving parts

This brown lock lever is a direct-replacement actuator that engages the appliance's locking mechanism so doors or lids stay securely closed during cycles. Restores proper latch movement and helps the door lock and release as intended. What it does:

• Moves the door/lid latch into the locked or released position when the appliance runs
• Replaces a worn, broken, or bent lever that prevents the lock from engaging
• Helps eliminate symptoms such as a door that won't latch, won't stay closed, or won't unlock at cycle end
• Works as the mechanical interface between the lock assembly and the door/lid

• One brown lock lever (single replacement part)

• Disconnect power and water (if applicable) before servicing to avoid shock or injury
• Access may require removing the control panel or door trim depending on model; follow OEM instructions
• Inspect mating latch and fasteners; replace any damaged clips or screws for secure fit

This rocker switch is a direct-replacement control button that restores reliable on/off input for the appliance. It replaces a worn or broken front-panel switch so controls respond correctly during normal use. What it does:

• Replaces a failed rocker/control switch used to send on/off or selection signals to the appliance's control circuitry
• Restores consistent electrical contact when the original switch is cracked, stuck, or intermittently working
• Commonly used when push/panel buttons no longer activate functions or display response is erratic
• Simple, single-function mechanical switch — no programming or calibration required

• Disconnect power to the appliance before attempting any service to avoid shock or injury
• Access may require removal of the control panel; keep screws and fasteners organized for reassembly
• Verify switch orientation and wiring before final reassembly; match connectors to original terminals
