What causes a potentiometer to fail?
Potentiometer valve position indicator failures are normally electrical in nature. An electrical short or open will cause the indication to fail at one extreme or the other. If an increase or decrease in the potentiometer resistance occurs, erratic indicated valve position occurs.
What happens when a potentiometer handle rotates?
When the potentiometer handle rotates, the rotor slides on the resistor body and the resistance between the GK105 rotor and the two stators changes. When the resistance of the moving part to one fixed part increases, the resistance of the moving part to the other fixed part decreases, as shown in Figure 3. When the resistance of the rotor to one stator decreases, the resistance of the rotor to the other stator increases.
How does a rocker potentiometer work?
When the rocker potentiometer is used as a current adjustment in the DC circuit, there will be a current passing through the sliding arm of the rocker potentiometer, and the resistance value will increase abnormally due to the anodization.
What are the requirements for a potentiometer?
The main requirements for the potentiometer are: (1) Resistance meets the requirements. (2) The contact between the center sliding end and the resistor body is good, and the rotation is smooth. For potentiometers with switches, the switch parts should be accurate, reliable and flexible.
What happens if the resistance is infinite?
If the resistance is infinite, the potentiometer will be damaged. (2) Then measure the contact between the center end and the resistance, that is, the resistance at both ends of BC. The method is that the ohm file of the multimeter is within the proper range, and during the measurement process, slowly rotate the shaft.
What is a moving contact on a resistor?
Generally speaking, a moving contact is moved on the resistor body to obtain a part of the voltage output.
What is a potentiometer?
The potentiometer is a kind of adjustable electronic component, which is basically a sliding rheostat. There are several styles of potentiometers, which are generally used for speaker volume switch and laser head power adjustment. How Potentiometer Assembles and Works.
What is the repair method of a potentiometer?
The Repair method of potentiometer failure. The potentiometer is equivalent to a continuously adjustable resistor. It can be understood as a variable resistor with a variable resistance. Simply speaking, by adjusting the rotation axis of the potentiometer, its output potential changes, so it is called a potentiometer. .
Why is my potentiometer so poor?
For some faults such as poor contact, the poor contact of the potentiometer is generally due to the oxidation of the contact. After the contact of the potentiometer is scraped, the fault is eliminated.
Why is my volume potentiometer making noise?
The problem with the general volume potentiometer is that there will be noise when the volume is rotated, or the volume of the two channels is different. At this time, the volume potentiometer should be replaced. After the potentiometer is used for a long time, the carbon film ages slightly. Cracks are the main cause of the deterioration ...
What is a volume potentiometer?
Amplifier volume potentiometers are various, but the common one is the double potentiometer, which is used to control the volume of the left and right channels , usually single-axis, and occasionally encounter double-layer dual-axis volume potentiometers. The problem with the general volume potentiometer is that there will be noise when ...

Can you use log potentiometers in volume control?
Unfortunately today the availability of log or antilog potentiometers is quite poor and the linear types are not suitable for use in volume control circuits. As usual, a solution can be find in the old literature, based upon the resistive loading of linear potentiometers.
Introduction
Read me: Before attempting this repair, read the provided guide notes (and warnings) for critical information.
Step 1 Unplug the receiver
In order to ensure there is no residual power, unplug the receiver for 48-72 hours. This will drain the capacitors so it can be safely serviced.
Step 2 Remove the bottom faceplate screws
If present, remove this screw. This was not in my unit, but may be in yours.
Step 3 Remove the side panel screws
Remove the 2 screws from the left side of the receiver. They are the same length.
Step 5 Remove the retention pin on the faceplate
If the clip in the faceplate is missing, the unit has been previously serviced. It is not essential, but try to keep it intact as the bezel will be loose without it.
Step 6 Remove the faceplate screws
After the faceplate pin is removed, remove the 2 screws that hold it to the chassis. Both screws are the same length.
Step 7 Remove the knob from the receiver
First time removal can be tricky. Work slowly on an unserviced receiver.
