Fuse Panel Fan

[Astpman]

2nd night of our camping trip and the fan for the fuse panel starts and stops every 15-20 seconds and runs for 3-5 seconds. Never had this happen and not sure what the problem is.

It's your converter cooling fan......your probably using lots of power..

Could there be a build up of dust on the power supply or using more 12v than the night before?

It's weird cause it's night now and no AC is on and just one light on in bathroom (we use as night light). I would think if it needs to cool the converter the fan would run for a couple minutes straight. It's just runs for 3 seconds, turns off for 15-20 seconds and cycles again continuously.

Depends upon the amount of load on the inverter. The fan adjusts depending on how many lights I have on. I'm looking to go with LED bulbs throughout the trailer and that should cut back on how much the fan runs.

Sounds like either the fan itself is going bad or the converter is failing.

What happens if you turn on several lights at the same time? Does it stay on then? Provided you have Incandescent lamps and not LED's.
