What happen when a posistor gone malfuntion?

When a posistor malfunctions, it can disrupt the intended temperature-dependent resistance behavior, leading to inaccurate readings or failure to regulate current properly. This may result in overheating, circuit damage, or erratic operation of the device it is controlling. In some cases, a malfunctioning posistor can cause the entire system to fail, potentially leading to safety hazards. Regular monitoring and maintenance are essential to prevent such issues.
