The WHIRLPOOL wp98008321 is a genuine OEM thermostat control knob finished in white, designed to restore proper temperature adjustment function to Whirlpool appliances. This knob interfaces directly with the thermostat shaft, giving the user accurate control over temperature settings. It is a direct factory replacement, meaning it meets the same fit and finish specifications as the original part. Appliance technicians and experienced DIYers install this knob when the original has cracked, broken, or become loose on the control shaft. No modification is required for a proper fit on compatible units.
This knob is applicable to Whirlpool appliances where the OEM thermostat control knob has failed or been damaged. Common scenarios include cracked plastic from repeated use, a stripped center bore that no longer grips the shaft, or a knob that has been lost during a previous service call. It is suited for residential appliance applications and is sourced directly from the original equipment manufacturer to ensure dimensional accuracy and color match.
Designed as an OEM-style replacement thermostat control knob for compatible Whirlpool appliances. Verify fitment using the appliance model number before ordering.
A licensed appliance technician or qualified DIYer can perform this replacement. Disconnect the appliance from its power source before beginning any service work. The knob typically pulls straight off the thermostat shaft and the replacement presses into place — consult the appliance owner's manual for model-specific guidance. Do not force the knob onto the shaft if resistance is felt, as this may indicate a shaft size mismatch.
