Begin by ensuring the appliance is turned off and unplugged‌ for ⁣safety. Gently pull⁤ out the⁤ existing knob by grasping it firmly⁢ and pulling straight from⁢ the control shaft. ​If the ⁢knob feels stuck, use a small flathead screwdriver wrapped⁤ in cloth to ​carefully pry it off without damaging the surrounding surface. ⁣Once removed,⁤ compare the old knob with your‌ new 4455115 temperature and time control ‍knob to verify compatibility and​ orientation.⁣ This step guarantees a perfect fit and ⁢smooth operation when installed.

Push the knob straight back onto the shaft until it ‌clicks or feels ‌securely seated. Avoid forcing it ‌to prevent ‍damage. test ⁢the knob by rotating ‍it through its full range of motion to confirm smooth and accurate control of ‌your appliance’s setting.
