and the Johnson Controls A-4000-632 is the industry standard for removing oil vapors and aerosols

Using it on non-specified brands may lead to improper start winding engagement or motor failure

It generates the necessary voltage through the thermopile in the pilot flame assembly to operate the solenoid

the internal diaphragm or plunger is likely compromised

Precise Calibration: Factory-set parameters of 32° F (close) and 55° F (open) optimize defrost cycle timing and energy consumption
