Never see stock internal fan run?


Does your PJ have a little toggle switch on the back?  If so, that should be a "fan on."  (Fan control on the older PJs was handled by a thermal "clixon" type thermostat--which isn't rated for the DC voltage, and often fails.)

An easy step might be replacing the internal inverter fan with a better one. I have a newer PJ, and it may have a high velocity fan. It sounds like a jet engine, but the inverter stays running even in 116° heat. I am only drawing 500W, though.

I will look in to a better fan

thanks for advice
