Spektrum S2100 fans won't spin on back?

[SpiffyDiddy]

I just got this charger second hand, it charges my batteries great but the fans on the back to cool the unit won't spin. I thought it has to hit a certain temperature for them to activate but they won't go even when the unit it HOT to the touch. Is this faulty or is there a setting I am missing?

Sounds like the fans are bad, or the relay, or whatever turns them on is. You can’t manually turn them on or off.

You could always try replacing the fan(s). Nothing to lose at this point. They are usually basic PC fans. AMZ has tons of them. Just buy what matches the fan and its volts and size. Not expensive. The charger needs to run cool. Bigger high capacity packs set to high amp rates really make the charger hottest. Need to address that. Can't play around with charging Lipos. No one wants a lipo fire.

Agreed.
Don't play around with Lipos and Chargers , especially if there's something in question about their proper functionality.
