This isolation transformer supplies the low-voltage control circuit that powers switches, relays and controls in the ventilation unit—restoring proper control operation and stable low-voltage output. What it does:

• Converts and isolates the appliance control circuit from main power to protect controls and reduce electrical noise
• Restores low-voltage power to switches, relays and electronic controls that fail when the transformer is bad
• Prevents intermittent or no-response symptoms from control panels and blower/light circuits
• Provides a direct replacement for the original transformer to maintain proper control operation

What's included: One isolation transformer Install notes:

• Disconnect all power to the appliance before starting any work
• Verify wiring locations and terminal markings; match connections exactly to the original transformer
• Inspect mounting and harness routing; secure transformer to prevent vibration
