• Controls power to motors, heaters and valves via internal relays and circuitry
• Can resolve symptoms like no response to controls, intermittent operation, or failure to start
• Helps clear erratic behavior caused by a damaged or shorted control assembly

• Disconnect power to the appliance before beginning any service
• Handle the control board and connectors by the edges; avoid touching components
• Transfer any user interface, bracketry or harnesses exactly as removed

This PTC relay is the start device that helps the refrigerator/freezer compressor get up to speed so the cooling system runs properly. Replacing a failed relay can restore normal compressor startup and improve cooling reliability. What it does:

• Provides the initial start boost to the compressor motor so it can begin running
• Stops the compressor from repeatedly failing to start, which can prevent cooling
• Commonly linked to symptoms like the compressor clicking, running intermittently, or the appliance not cooling
• Works as the replaceable electrical start component — not a capacitor or overload protector

• Disconnect power before accessing the compressor area to avoid shock
• Verify wiring and match the relay visually and by part number before installing
• Handle gently; do not attempt to modify or repair the relay
