Whirlpool WP74008940 Range Infinite Switch
Product Description
The Whirlpool WP74008940 is an infinite switch, referred to as a burner control switch, intended for Whirlpool brand ranges. This knob-like component is necessary in controlling the power delivered to your cooktop's surface elements. Despite ordinary on/off switches, the infinite switch has a variable resistance configuration. As you turn the knob, the electrical resistance within the circuit changes, providing you smooth and accurate control of the heat output. This translates to simmering delicate sauces over low heat or bringing them to a fast boil.Replace a defective endless switch to regain control of your cooktop. Burners that do not respond at all, changing heat levels, or an inability to control the temperature are all common symptoms of a faulty switch.
