Customer Questions and Answers for Starting Device (Compressor Start Relay) by Bosch

This refrigerator compressor starting device engages the compressor's start winding to begin operation, then disengages for normal running. Replacing a weak or failed unit can restore reliable starts and help bring cooling performance back to normal.

• Provides the proper start circuit to the compressor motor at power-up
• Automatically disengages after start for normal operation
• Common symptoms of failure: clicking from the compressor area, compressor won't start or starts then stops, and warm temperatures
• Used when diagnosing no-cool or intermittent-cool conditions related to a failed start relay

• Disconnect power and pull the refrigerator forward for safe rear access
• Remove the rear access panel; note wire positions, then pull the old starting device straight off the compressor pins
• Transfer wires to the new device in the same locations and press it fully onto the compressor terminals
• Reinstall the access panel, restore power, and allow temperatures to stabilize
