This tray transformer is a direct-replacement transformer assembly that provides the proper low-voltage power for the appliance tray assembly, restoring reliable operation and control. Use it to replace a worn or failed transformer without modifying wiring or controls. What it does

• Steps down line voltage to the tray assembly's required control voltage so tray components receive stable power
• Restores power to tray-related circuits when a failed transformer causes loss of function
• Common symptom: tray functions, lights, or heater do not operate or respond
• Designed to fit and mate with the factory tray wiring and mounting points for a clean swap

• One tray transformer assembly

• Always disconnect power to the appliance before starting work to avoid shock hazard
• Match the replacement to the original by part number and connector style before installing
• Basic hand tools are typically required; handle wiring and terminals carefully to avoid damage

This cover harness organizes and protects the main wiring inside a side-by-side refrigerator, helping keep electrical connections secure and routed safely for reliable operation. Use it when wiring cover damage or wear exposes connectors. What it does

• Routes and protects internal wiring behind refrigerator panels to prevent chafing and accidental disconnection.
• Secures connector positions so components receive consistent power and signals.
• Common symptom: visible frayed wiring or loose connectors behind the fresh-food/freezer panel.
• Can be a factor when intermittent component operation or wiring-related faults are observed.

• Disconnect power to the appliance before service to avoid shock or damage.
• Remove panels per the OEM service instructions to access the old harness; note connector positions before removal.
• Inspect connectors and adjacent wiring; replace any damaged clips or grommets to prevent future abrasion.
