Supco ES9400 Infinite Switch Range Surface Unit

Product Description

The SUPCO ES9400 is an electric infinite switch designed for range surface unit control on residential cooking appliances. An infinite switch regulates the power delivered to an electric burner by cycling the heating element on and off at varying intervals, allowing the user to set heat levels anywhere between low and high without fixed steps. This switch fits the large surface unit position on compatible electric ranges, ovens, and stoves. It is typically installed by appliance technicians or experienced trade professionals during burner control replacement service.

The ES9400 is suited for residential electric range applications where the original large surface unit infinite switch has failed or worn out. Compatible applications include select models from Whirlpool, Maytag, Kenmore, KitchenAid, Roper, and other related brands. It serves as a direct service replacement for the large burner position on qualifying units in these product families.

Key Features

• Infinite switching design provides stepless heat control across the full range of burner output
• Rated for the large surface unit position on compatible electric ranges
• Direct replacement design for qualified Whirlpool-platform and related brand appliances
• Electric operation compatible with standard residential range wiring configurations

Compatibility

Compatible with select models of Whirlpool, Maytag, Kenmore, KitchenAid, and Roper electric ranges, ovens, and stoves. Verify the original part number and burner position against your unit's service documentation before ordering.

Installation Notes

Infinite switch replacement is typically performed by a qualified appliance technician. Always disconnect power to the range at the circuit breaker or by unplugging the unit before beginning any service work. The switch mounts to the control panel and connects to the burner element and power leads - consult the appliance wiring diagram for terminal identification. Do not restore power until all connections are secured and the panel is fully reassembled.
