Best Built Ultrasonic Replacement Knob for Timer & Temperature Control

Keep your Best Built ultrasonic running smoothly with this genuine replacement knob, designed specifically for the timer and temperature control knobs on Best Built ultrasonic cleaners. When a knob becomes damaged or worn, this direct replacement restores full functionality without the need for a service call.

Best Built recommends using the on/off switch to turn your ultrasonic on and off—not the timer. Using the timer to power the unit down will shorten the service life of the analog timer and can cause the timer knob to break.

Features

• Direct replacement for timer and temperature control knobs on Best Built ultrasonics
• Restores proper operation after knob damage or wear
• Genuine Best Built replacement part

Notes

Always use the dedicated on/off switch—not the timer knob—to power your Best Built ultrasonic on and off. Repeated use of the timer as a power switch accelerates wear on the analog timer mechanism and may result in knob failure.
