It isn't hot weather where I am.
Is this normal.

Hi Ted, yes its normal. Its not the weather outside, its the heat generated by the electronics in close quarters where the converter is located. RonB
Normal...and a good thing...

I had a Progressive Dynamics converter in my last rig and never heard a fan is why I ask.
Thanks

And now you have a Parallax.... ;)
Hi Ted; I have a newly installed PD 4655, and I have never heard the fans, actually there are two of them. I've had it for almost a year, but it wasn't high on the priority list, and just got put in a few months ago. The new updated fuse panel was the hard part. The fuse panel and converter used SO parts. Surface Outline, IC's, transistors, resistors, capacitors in the form of chips, placed and soldered on both sides of the printed circuit board. Small dense circuitry. Such a leap in technology over the original converter I had, whose design was very "in the mid 60's". The new 'switcher' has very good quality DC. Precise and stable. With higher efficiency, it generates less heat than the old, 60 Hz, transformer based Parallax. In addition, the PD, can be converted to LiFePO4 battery operation by changing a jumper. RonB

I went from the original converter in my 1995 TK to that upgrade.
I hear ya on how the technology has improved!

Are you using any 12-volt appliances or accessories during this time? Was the battery low, when the converter was powered up?
The fan should have its own thermostat.

No and no.
I understand it might come on during a load but there wasn't any I was aware of
Mine always comes on when I first power it up, then it slows down or shuts off

If you have solar with good sun exposure currently, try turning off the converter circuit breaker. If the fan no longer comes on, measure your battery voltage at the batteries. if voltage is not low, then you may have some other 12V load on the system. see what your solar charge controller is showing. If the current it produces is higher that expected for fully charged batteries (> 3Amp), then you have more than the fridge drawing power.

This may be normal for your converter, the 75-amp converter LD used a few years ago fan was on all the time.
Maybe Mike Coachman will clime in with his experience with his new LD’s converter’s fan.
Our LD’s PD 9270 converter’s fan almost never runs, only when the battery is deeply discharged.

The fan does run on and off when on shore power. It’s normal and nothing to be concerned about.

Are you talking about the original converter, Mike?
I replaced the original Parallax with the PD 4655 set up for charging the lithium batteries at 14.5 volts. The fan is not loud and not objectionable. It only runs for a short period occasionally.
