This 5/8" ODF solder moisture liquid indicator is engineered for high-pressure applications

providing a hard break in the safety circuit when internal plenum temperatures exceed the factory-defined threshold

Using an incorrect color-coded spring will lead to calibration failures and inaccurate pneumatic valve modulation

Installing this on a 230V circuit will cause immediate failure of the heating element

Common signs include the inducer motor running without ignition
