A small replacement mounting screw used to secure range hood and ventilation components. Restores loose or missing fasteners so panels and assemblies sit firmly and stop rattling or shifting during use. What it does

• Secures trim, grille, brackets or other small assemblies to the main housing
• Replaces a missing or stripped screw that causes rattling or loose parts
• Helps restore proper alignment of removable panels and covers
• Works as a direct fastener when the original screw is lost or damaged

• Turn power off to the appliance before working on vents or housings

• Tighten until snug; avoid over-tightening which can strip threads or crack plastic
• If threads are damaged, replace the mating clip or insert before using this screw

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

• 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

• Helps maintain proper airflow direction and vent hood performance
• Commonly used when the original panel is cracked, bent, or missing fasteners

• One replacement cover panel

• Installation requires removing the old cover; retain or replace mounting screws as needed
• Use basic hand tools; support the cover during removal to avoid scratching adjacent surfaces
• Disconnect power to the appliance before working near electrical components

This is a replacement mounting screw used to secure components on compatible Broan range hoods and ventilation assemblies. It provides a secure, corrosion-resistant fastening to restore proper part alignment and stability. What it does:

• Fastens panels, brackets, or small components to keep assemblies stable and aligned
• Restores loose or rattling parts that may vibrate during operation
• Helps maintain safe, secure connections for venting and electrical component support
• Small, OEM-matched fastener to fit the original screw hole and thread pattern

• Use appropriate screwdriver or driver bit to avoid stripping the head
• Tighten securely but do not overtighten to prevent thread or component damage
• Disconnect power to the appliance and ensure the unit is cool before servicing
• Inspect surrounding hardware for replacement

The Light Socket is an OEM replacement part for Broan range hoods. This electrical fitting provides a power connection point for light fixtures above stovetops. A faulty socket jeopardizes safe operation.

Causes of a bad socket can include loose wire connections allowing arcing or shorts, moisture intrusion corroding terminals, or cracking of plastic insulation. 

Symptoms of a bad light socket include: 

• Intermittent or non-functioning lights  
• Warm socket housing or abnormal smells/sounds
• Tripped breakers or blown fuses servicing the range hood

This OEM component fits additional brands like Thermador, Viking, and some Kenmore range hood models using equivalent Broan designs.

Secures the grease filter in your Allure range hood. This filter spring kit replaces worn or missing springs so the filter stays seated, reducing rattling and preventing the filter from dropping during operation.

• Applies spring tension to hold the grease filter in place
• Helps maintain proper airflow by keeping the filter fully seated
• Reduces vibration and noise from a loose filter
• Common symptoms: filter falls out, hangs loosely, or is hard to keep latched

• Disconnect power at the breaker before servicing the hood
• Remove the grease filter(s) to access the spring location
• Wear cut-resistant gloves; sheet metal edges can be sharp
• Ensure springs are fully seated in the factory slots/tabs, then test-fit the filter

This replacement control transformer provides the low-voltage power needed for range hood controls and lights so your hood operates reliably. Fits applications that use a dedicated small transformer assembly. What it does:

• Supplies low-voltage power to hood control circuits and light switches
• Restores power when lights, fan controls, or electronic switches fail due to a bad transformer
• Can cause intermittent operation, no-power symptoms, or humming if failing
• Common repair for range hoods with burned or open transformer windings

• Always disconnect power at the breaker before accessing electrical components
• Basic hand tools and wire-connection skills are typically required; preserve original wire connections or photo them before disconnecting
