Electrical smell coming from AC vents

[irish57]

Hello fellow RV'ers,

I have an '03 Itasca Suncruiser, 38G with a Coleman Mach basement AC unit. While boondocking tonight, my wife and I experienced an electrical smell in our rig, and pinpointed it to the air coming from the vents. I shut off the AC, and then checked the AC unit outside. There was smoke with the same electrical smell coming off the unit. My bad, as we have not had the AC unit checked since we bought it last year.

Any ideas what this might be?

Thank you, Doug

Likely one of the capacitors has bit the dust.

Could be anything from a loose electrical connection (wire burning) to a motor to hot (loose wire can cause high amps which can burn the windings on the motor). Even the small transformers can put off that burn smell. Wish I could really help but it really needs a a/c service to find the source of the smell and what caused it.
