How Does a Thermistor Compare to a Thermostat?

While both thermistors and thermostats are temperature sensors, they function quite differently. As previously mentioned, a thermistor measures changes in resistance as the temperature changes, while a thermostat opens or closes a switch depending on the temperature.

Thermistors have several advantages over thermostats. They are more accurate, as they can detect smaller temperature changes more quickly. They are also more efficient, as they use less energy and can maintain a more consistent temperature over time.

Thermostats, on the other hand, are simpler and less expensive. They are still reliable and commonly used in many household appliances.

Overall, while both sensors have their strengths and weaknesses, the use of a thermistor is becoming more common due to its increased accuracy and efficiency.

The Role of the Thermistor in Drying Cycles

Now that we understand the importance of temperature control in drying, let’s explore the specific role that a thermistor plays in different drying cycles.

In regular drying cycles, the dryer thermistor works by constantly monitoring the temperature inside the dryer drum. It then sends a signal to the control board to either turn the heating element on or off, depending on whether the temperature is too high or too low. This ensures that the dryer stays within the optimal temperature range for efficient and effective drying.

In delicate drying cycles, the thermistor plays an even more critical role. Delicate fabrics require lower temperatures to avoid damage or shrinkage. The thermistor in the dryer detects when the temperature is becoming too hot and signals the control board to shut off the heating element before any damage occurs.

Timed drying cycles also rely on the thermistor to accurately maintain the set temperature for the specified length of time. The thermistor helps ensure that the clothes are exposed to the right amount of heat for the desired drying duration, resulting in perfectly dried clothes every time.
