The Range Infinite Control Switch is an OEM part for Whirlpool ranges. This switch is used to control the heat levels of the surface burners, allowing for precise temperature adjustments. It works by regulating the electrical current that flows to the burner elements, enabling users to set the burners to their desired heat setting from low to high.

Symptoms of a failing Range Infinite Control Switch include:

• The burner not heating up or getting too hot regardless of the setting
• Inconsistent or fluctuating heat levels
• The control knob feeling loose or not turning smoothly
• The burner not turning on or off properly
• Electrical sparking or unusual noises from the control switch area

Causes of a bad infinite control switch can include wear and tear from regular use, internal electrical failures, damage from overheating, or mechanical issues within the switch mechanism.

This OEM Whirlpool part is also compatible with some models from Maytag, KitchenAid, Jenn-Air, Amana, Magic Chef, Admiral, Norge, Roper, and Kenmore. 

The Infinite Switch is an OEM part for Whirlpool ranges and cooktops. This part controls the temperature of the small burner on electric ranges and cooktops by regulating the power supplied to the burner. The infinite switch allows for precise temperature settings, providing the flexibility to cook a wide variety of dishes by adjusting the heat level as needed. 

Over time, infinite switches can wear out or malfunction, leading to issues with controlling the burner's temperature.  

Symptoms of a bad Infinite Switch include:

• The burner does not heat or heats intermittently
• The burner heats to full power regardless of the setting
• Inability to adjust the burner's temperature accurately
• Physical damage to the switch, such as cracking or melting

This OEM Whirlpool part is also compatible with Maytag, KitchenAid, Jenn-Air, Amana, Magic Chef, Admiral, Norge, Roper and some Kenmore models.
