Washer and dryer combo knobs make it easy to select cycles, temperature settings, dry times, and start or pause functions. Because these knobs are touched every time the appliance is used, they can crack, loosen, strip around the shaft, or stop turning the control behind the panel. When that happens, the machine may seem like it has an electrical problem even though the control knob is simply no longer gripping the stem correctly.

A replacement knob should match the appliance model, shaft style, color, and control function. A timer knob, selector knob, start knob, and cycle knob may look similar, but they can have different inner inserts, indicator markings, and mounting shapes. Matching by model number is the best way to avoid a knob that fits loosely or points to the wrong cycle position. If you are comparing more than one control issue, the full washer and dryer combo parts collection can help you review knobs, switches, sensors, boards, and related parts together.

So, what is the knob on a washing machine called? It depends on the function. You may see it listed as a control knob, timer knob, cycle selector knob, temperature knob, start knob, or knob and clip assembly. On washer and dryer combo units, one knob may control wash cycles while another controls drying options. Always compare the old part location and markings before choosing the replacement.

Common Washer and Dryer Combo Knob Types

When a Knob Replacement Can Solve the Problem

A broken knob can make the appliance feel more serious than it is. If the knob spins but the setting does not change, the plastic insert may be stripped. If the knob falls off, the retaining clip or inner sleeve may be missing. If the indicator mark no longer lines up with the actual cycle, the knob may have been forced onto the shaft in the wrong position or may not be the correct replacement for that model.

So, can you replace the timer knob on a dryer? Yes, in many washer and dryer combo models, the timer knob can be replaced without replacing the full control panel. First disconnect power, then pull the old knob straight off unless your model uses a retaining clip or set screw. Compare the shaft shape before installing the new knob. If the knob slides on smoothly and turns the control stem firmly, the repair is often quick.

If the knob feels normal but the control does not respond, the issue may be behind the panel. A damaged timer, selector switch, or electronic control may need inspection. In that case, the washer and dryer combo circuit board collection may be useful if the display, cycle selection, or response from multiple buttons is failing at the same time.

Before You Buy a Replacement Knob

Replacing a Washer Timer Knob

So, how do you replace a washer timer knob? First off, start by disconnecting power to the unit. Then hold the knob firmly and pull it straight away from the control panel. If it does not move, check for a hidden clip, small screw, or push-and-turn release. Once the old knob is off, align the new knob with the shaft and press it on evenly. Do not force it, because too much pressure can crack the insert or damage the control stem.

If the knob broke because the user had to turn it with extra force, the control behind it may also be stiff or worn. A knob should not need heavy pressure to select a cycle. If the knob becomes hard to turn again after replacement, inspect the control shaft, wiring, or control board before ordering another knob. A sensor issue can also make the selected cycle behave incorrectly, so symptoms like early shutoff or wrong drying time may point toward the washer and dryer combo sensor collection instead of the knob alone.

One downside of a washer and dryer combo is that many controls serve both washing and drying functions in one compact panel. This makes the correct control part more important. A knob that looks close may still select the wrong setting if the shaft position, printed markings, or internal insert do not match the original design. That is why model-number matching should come before color or appearance.

If the appliance will not start unless the door is pushed firmly, the knob may not be the cause. A door latch, lock, or hinge issue can interrupt the start circuit. For that type of symptom, check the washer and dryer combo door category along with the control knob so the repair stays focused on the actual failure.

Small hardware can matter too. If a knob was removed during a panel repair, missing screws or fasteners can leave the panel loose and cause the knob to sit at an angle. The washer and dryer combo screw collection can help when the problem is missing mounting hardware rather than the knob itself.

A properly fitted replacement knob restores simple day-to-day control. It should sit flush, turn smoothly, point to the correct cycle, and feel secure without wobbling. Once replaced, run a short cycle to confirm that the knob position matches the selected wash or dry function.
