The thermistor feeds accurate temperature readings back to the control board, allowing the heater to manage fan operation and safety cut-outs correctly. When this lead fails, you'll often see intermittent faults, incorrect fan behaviour, or temperature-related error codes — making it a common service item for Australian tradies maintaining Braemar systems.\u003c\/p\u003e\n\u003cp style=\"font-size: 16px; line-height: 1.6; margin-bottom: 20px;\"\u003eBest for: Servicing and repairing Braemar gas ducted heaters where the thermistor lead has failed, degraded, or is throwing sensor open\/short faults.\u003c\/p\u003e\n\u003ch2 style=\"color: #007acc; border-bottom: 2px solid #f0f0f0; padding-bottom: 8px; margin-top: 35px;\"\u003eCompatibility\u003c\/h2\u003e\n\u003cp style=\"font-size: 16px; line-height: 1.6; margin-bottom: 20px;\"\u003eThis is a genuine Braemar part designed for the TQS 720 gas ducted heater.
