Nti 83035 1/4 Inch Npt Thermistor for M100V Ti100-400 Condensing Gas Boiler

Product Description

The NTI 83035 is a 1/4 inch NPT thermistor designed for use with NTI condensing gas boiler models M100(V) and Ti100-400. A thermistor is a temperature-sensing resistor that changes its electrical resistance as the surrounding temperature changes. In a hydronic heating system, the boiler control board reads this resistance to determine water or pipe temperature. That reading tells the system when to fire the burner, when to modulate the heat output, and when to shut down. Without an accurate thermistor signal, the boiler cannot regulate temperature properly, which leads to inefficient operation, nuisance lockouts, or unsafe conditions. The NTI 83035 is the factory-specified replacement part for these boiler models, making it the correct choice for service technicians performing diagnostics or preventive maintenance. The 1/4 inch NPT threaded fitting allows direct installation into existing ports on the heat exchanger or piping, giving technicians a secure, leak-free connection without adapters. NTI condensing gas boilers are high-efficiency units commonly found in residential and light commercial applications. They operate by extracting heat from the flue gases, which causes condensation. Temperature sensors like this thermistor are critical components in maintaining that high-efficiency operation. When a boiler throws a fault code related to temperature sensing, this is one of the first components an HVAC technician will inspect and test. Replacing a faulty thermistor with the correct OEM part restores accurate temperature feedback to the control board and gets the system back online quickly. Trade professionals servicing NTI boilers should keep this part on hand as a stock item to reduce return trips and minimize customer downtime. The NTI 83035 thermistor is a direct OEM replacement for reliable, accurate temperature sensing in condensing boiler applications.
