Parts for Thermador TSS48QBB: 22 - Lower Unit & Tubing Parts

This is an electrical connector strip used inside the refrigerator to join wiring harnesses or connect components on the control board. It ensures a secure electrical connection between circuits. Replace this connector if you notice intermittent power issues, error codes, or if the strip shows signs of burning, corrosion, or damaged pins.

This tube-condenser inlet routes refrigerant into the condenser, keeping the sealed refrigeration loop functioning properly. Replacing a damaged inlet helps restore reliable heat exchange and stable cooling performance. What it does:

• Directs refrigerant from the evaporator/compressor area into the condenser for heat rejection
• Maintains a sealed refrigerant path to support normal cooling operation
• Faulty or leaking inlets can cause reduced cooling, visible refrigerant/oil residue, or extended compressor run time
• Designed to mate with factory fittings and refrigerant lines for proper flow

• Disconnect power before starting any repair; work on sealed refrigerant components requires proper recovery of refrigerant
• Installation may require brazing/soldering, line-fitment, and leak testing
• Inspect mating fittings, gaskets, and clamps; replace any damaged sealing components
• Wear safety glasses and gloves; follow local codes for refrigerant handling and disposal

Refrigerator not cooling properly? A faulty heat exchanger disrupts the cooling cycle. This sealed system component requires advanced repair skills.

Not cooling properly or frost building up in your freezer? The evaporator coil absorbs heat to cool your fridge. Moderate DIY repair with proper tools.

Fix excessive frost buildup in your refrigerator with this evaporator defrost heater. Restores normal airflow and cooling by melting ice during cycles.

This drain pan collects and channels defrost and condensation water away from the evaporator to prevent leaking and overflow. Use this replacement to restore proper water flow and reduce pooling under the appliance. What it does:

• Catches defrost and condensate from the evaporator system
• Directs water toward the drain or evaporator heater for evaporation
• Helps prevent water leaks, puddling, and potential floor damage
• Supports normal defrost cycle drainage

• Disconnect power to the appliance before service
• Remove access panels or kickplate to reach the pan; keep small fasteners organized
• Clean surrounding area and drain path before installing the new pan
