A Bunn 43500.1032 Temperature Sensor detects heat changes to support accurate control and steady performance.
The temperature sensor monitors boiler temperature and sends resistance-based feedback to the control system so the machine can regulate water heat accurately during brewing. Its NTC design matters because it responds predictably to temperature changes, supporting stable beverage quality, proper heating cycles and protection against overheating.
The temperature sensor may need to be replaced if the machine shows inconsistent water temperature, erratic brewing performance or boiler heating that cycles too long or shuts off too soon. Physical signs can include damaged wiring or corrosion and environmental signs may include scale buildup, moisture exposure or heat-related wear that can affect accurate temperature readings.
