Whirlpool WP3957822 Timer Knob Washer Part

Product Description

The WHIRLPOOL WP3957822 is a timer knob designed for use on Whirlpool-brand top-load washing machines. This knob mounts to the timer shaft on the washer control panel, allowing the user to select wash cycles. It measures 2.25 inches by 2.25 inches by 1.0 inch and is a direct OEM-style replacement part. HVAC and appliance technicians as well as experienced DIYers install this part during routine control panel service or after a knob cracks, strips, or breaks off the timer shaft. Replacing a damaged timer knob restores full cycle-selection function without replacing the entire timer assembly.

This knob fits a range of Whirlpool top-load residential washing machines across multiple model series. It is used in laundry appliance service calls where the original timer knob has become cracked, faded, or mechanically stripped. The part is sized and keyed to match the original timer shaft configuration on compatible models. Installation is straightforward and requires no special tools in most cases. See the compatibility section below for verified model numbers supported by this part number.

Installation Notes

Disconnect power to the washing machine at the outlet or circuit breaker before beginning any service work on the control panel. The knob typically pulls straight off the timer shaft and the replacement presses firmly into place, though some configurations may use a set screw. Confirm the shaft profile and knob keyway match before final seating. This type of repair is within the scope of appliance service technicians and knowledgeable DIYers familiar with washer control panel disassembly.
