• Outlet Thermistor - Boxed

The Bard 8408-043BX Outlet Thermistor is an OEM temperature sensing component used in Bard wall-mount air conditioners and heat pumps to monitor outlet air temperature and report that reading to the unit controls for stable operation and proper staging and protection. When a thermistor drifts out of range or fails, Bard equipment may short cycle, display sensor faults, or struggle to maintain setpoint, so replacing it with the correct factory sensor helps restore accurate feedback and dependable performance. Because sensor style and resistance curve can vary by model and control board, confirm 8408-043BX against your unit data plate and the Bard parts list before ordering to ensure proper fit and correct temperature readings.
