Description

This compressor is the sealed refrigeration pump that circulates refrigerant to remove heat and keep the appliance cold. It restores cooling performance when the compressor has failed or is no longer running reliably. What it does:

• Compresses and circulates refrigerant through the refrigeration system to enable cooling.
• Replaces a defective or noisy compressor to help restore normal temperature control.
• Addresses symptoms such as no cooling, warm temperatures in the compartment, or a compressor that won't start or runs continuously.
• Designed for use with specified 220–240V, 50 Hz household refrigeration systems.

What's included: One compressor unit. Install notes:

• Disconnect power and allow recovery of refrigerant before removal; work with pressurized refrigerant only if licensed and equipped.
• Replacement requires proper brazing/welding, oil charge verification, and system evacuation/charging to OEM specifications.
• Verify electrical connections, mounting, and line sizes match the appliance; use original mounting hardware when possible.
