Bosch Freezer GSU3103 Parts

This temperature limiter safeguards the evaporator defrost heater by opening the circuit if temperatures rise too high. Replacing a failed limiter restores defrost safety and helps prevent frost buildup and inconsistent cooling performance.

• Protects the defrost circuit by cutting power to the evaporator heater when an over-temperature condition is detected
• An open/failed limiter prevents the heater from energizing, causing frost accumulation on the evaporator and warm refrigerator temps
• Designed to be installed in the original location and orientation for accurate temperature sensing

• Disconnect power before servicing; evaporator fins and sheet metal are sharp—use cut-resistant gloves
• Access the evaporator compartment and note the limiter's original mounting and wire routing before removal
• Transfer any clips/insulation sleeves and reconnect wiring to the same terminals; do not bypass this safety device
• Reassemble, restore power, and monitor for normal defrost operation

This is a filter drier used in the sealed refrigeration system to remove moisture and contaminants from the refrigerant lines. It is a small cylindrical component typically located along the refrigerant tubing between the condenser and the capillary tube. Replace this part if the refrigerator or freezer is not cooling properly due to a restricted or saturated drier, typically during a sealed system repair.

Replacement mounting screw for bottom-mount refrigerators. Secures panels, brackets, and components to the chassis. Needed when original is stripped, lost, or damaged during repairs.

This starting relay engages the refrigerator/freezer compressor during startup so the appliance reaches proper cooling quickly and reliably. It replaces a failed relay to restore normal compressor startup behavior. What it does:

• Provides the initial electrical kick to the compressor motor during startup
• Stops the compressor from stalling at power-up and helps prevent repeated restart attempts
• Common symptom of failure: fridge/freezer not cooling, compressor hums but won't start
• Other symptom: intermittent starting or frequent clicking noises when the compressor tries to engage

• One starting relay

• Disconnect power to the appliance before accessing the compressor or handling electrical components
• Mount in the original relay location and ensure secure electrical connections; do not force terminals
