An NTC thermistor is a resistor whose resistance decreases as temperature increases

The most common accelerating factors are operating the dryer with a worn or broken belt (which allows the drum to sag and puts extra weight on the rollers)

Made from high-strength rubber with reinforced ribs — resists cracking

Both rollers must be replaced at the same time — replacing only one results in uneven drum support and accelerated wear on the new roller
