Groen 152960 High Limit Thermistor

The Groen 152960 High Limit Thermistor monitors temperature levels within the heating system by measuring electrical resistance changes in response to rising heat conditions and sending signals to the control circuit when preset temperature thresholds are approached or exceeded. It operates by continuously sensing thermal variations and altering resistance value, allowing the control board to interpret temperature fluctuations and initiate interruption signals to prevent further heating once the limit condition is reached during operation cycles. It is positioned within the heating chamber or adjacent to the heat source of compatible equipment.
