A defective temperature control can be replaced using a homemade knob or by ordering a replacement knob from the manufacturer of the crock pot or an online retailer. Replacement crock pot temperature control knobs can be purchased from retailers such as Amazon.com and eReplacementParts.com.
It is important to make sure that the knob ordered fits the model of crock pot that needs the replacement. Many people have also made their own knobs using a variety of materials, such as rock, wood, and clay. Ordering replacement knobs directly from the manufacturer can help ensure that the knob purchased is the right fit.
