    It's just that I maintain 5 a.s.e. certifications just for electrical and electronic systems as I have shown. So I just can't let this fire hazard go. The ONLY way an IC can properly control a relay or solenoid or a coil of any sort is with what is called a 'coil driver circuit' which is like it's own little solid state relay of sorts or MOSFET that can handle switching very fast but MOST IMPORTANTLY it does not let the power or ground being applied to the coil touch the driver circuit because when switched off the KV spike from the collapsing field will destroy electronics and potentially set fires. But if we already have a MOSFET to control this relay or solenoid then why do we not just use that MOSFET to control the heater directly? I'm just speaking of 'proper use' of electronic devices and components as taught by a well funded education. What about you? Where did you not learn the correct way to use a solenoid or relay?
