Noisy WFCO fan.

[goducks10]

When plugged into shore power and turning on a bank of 3 LED lights or 2+ in another area the fan on the WFCO converter really revs up.
FYI I have 4-6V Costco batteries that are in great shape. Digital volt readout shows 13.5-6 when charging and 12.5-7 when shore is disconnected.
Is it normal for the fan to rev up a lot. It seems like it's gotten a little noisier over the past year. Not noisy like a bearing going out. Noisy like revving up faster than in the past.
I guess my question is why does it need to rev up like it does?

Already been thinking thats my next step.

What is the AC Voltage?
IIRC the Fan is a 120V AC fan not DC
AC Voltage fluctuations would change fan speed

Or could be issue with the thermal sensor/t-stat that turns fan on/off

It's left plugged in 24/7 when not dry camping. I guess it's still working even in trickle mode.
Not sure on the AC volts.
The fan only comes on when there's a draw on the converter.
I was just thinking that it shouldn't run maxed out when only 3 LED lights are on. I didn't think LED's drew enough amperage to make the fan need to kick on.

Try some different light loads to see if those LEDs are causing a problem.

I replaced the cheap fan in my WFCO with a ball bearing fan the first year. I guess they saved just a few pennies.
