Loud noise while charging 2015 Leaf SL

My 2015 Nissan Leaf suddenly began making a loud noise while charging. This followed a trip where I used a variety of chargers, L1, L2, L3. Somewhere along the way the noise started and now it continues whenever I charge. Any advice?

Sounds like the fan for the coolant loop is constantly running. Is the ambient temperature really hot?

Have you used an OBD2 dongle and LeafSpy to check for codes and temperatures yet? If not, do that and post back temps and codes...

It has been in the high 20's and low to mid 30's...and very humid. I will try what you suggest with the dongle and leafspy and report back.
Thanks,

It definitely sounds like a cooling fan running on high. I must be psychic today: I expected to hear that noise before it started, despite never having heard it myself...

Would be helpful too if you share a video of what going on under the hood, rather than one just showing the charging port. If my guess is right, you'll see the cooling fans spinning near the radiator at the front of the "engine" compartment.

The fans look like this:

Found a useful post for you, it's likely the coolant temp sensor:

Should be pretty easy to dig it out to check the resistance, as per that post...

Looks like Nissan changed the part number in August of 2015, so check your build date before ordering the sensor:

That post was very helpful. Thanks so much.

You bet, hope that's the problem as a $45 part replacement ain't so bad

Also make sure the coolant is full.
