If the hot surface ignitor serves as a flame sensor (flame rectification)

it provides consistent millivolt output to the safety shut-off valve

It provides the necessary clamping force to maintain position without the frequent slippage seen in generic aftermarket alternatives

maintaining optimal static pressure and airflow efficiency

How do I determine the flow capacity of the 143-16-023-02 orifice

Danfoss 060L202966 Temp Control Els PW 17895 If the hot surface ignitorThe Danfoss 060L202966 KP73 Temp Control is a heavy duty mechanical temperature switch designed for precision regulation in commercial refrigeration and HVAC systems. Built with a remote bulb sensor and an adsorption charge, this unit provides reliable SPDT contact switching based on temperature rise. Operating within a temperature range of 31F to 59F ( 35C to 15C), the KP73 is ideal for air conditioning freeze protection and general process cooling.
