Large turning noise in adjustable potentiometers is a problem we often encounter. How can we solve it? Today, we'll teach you how to clean and repair the adjustable potentiometer to eliminate the loud turning noise.

The specific method involves allowing the pure alcohol cleaning solution to flow onto the carbon film inside the adjustable potentiometer by folding it. Continuously turning the handle causes the contacts to slide over the carbon film, achieving the purpose of cleaning both the carbon film and the contacts. This cleaning can be done while the device is powered on. It is crucial to use only pure alcohol. Then, turn the handle and listen to the noise level, continuing until the noise disappears. How exactly does the cleaning solution reach the carbon film?

For the linear sliding carbon film potentiometer: Apply by dripping into the gap of the handle.

2. For carbon film potentiometers that cannot be externally infused: clean the outer shell after opening the adjustable casing.

For potentiometers with large gaps at the pins: Naturally, drops fall into the pin gaps.

For potentiometers with significant gaps at the turning handle: Apply drops directly into the gap at the turning handle.
