This lower cooling fan assembly circulates air to cool internal components and help maintain proper airflow in the appliance. Replacing a worn fan restores quieter operation and helps prevent overheating of electrical parts. What it does:

• Moves air through the appliance cabinet to aid component cooling and temperature regulation.
• Reduces hot spots around controls, electronics, and motors that can cause premature failure.
• Commonly used when you hear unusual noise from the lower area or detect reduced airflow.
• Supports overall appliance performance and reliability by maintaining designed ventilation.

• One lower cooling fan assembly as shown

• Disconnect power before attempting any service to avoid electric shock.
• Inspect surrounding mounts and ducts for damage; replace any broken clips or supports.
• Use basic hand tools; confirm correct orientation and secure mounting before restoring power.

This limit switch is a safety control for compatible cooking appliances. It opens or closes an electrical circuit when a preset limit is reached—commonly temperature or travel—helping protect components and ensure proper operation of heating and latch systems.

• Monitors a specific limit at its mounting point (temperature or mechanism travel, depending on model)
• Opens/closes the circuit to interrupt or allow power to related components
• A failed switch can prevent heating, stop self-clean from starting, or keep the door from locking/unlocking
• Helps protect wiring and controls from damage during abnormal conditions

• Disconnect power to the appliance and allow all components to cool before servicing
• Access location varies by model; take photos and label wires before removal
• Transfer wires one at a time to the new switch; secure with existing hardware
• If the old switch tripped due to overheating or binding, inspect fans, vents, and latch/linkages to correct the root cause
