Where is the switch for the blower fan?

[virtualburton]

Hi all - does anyone know where the switch is that controls the blower exhaust fan in the engine compartment? I see it there but have not found the switch...

I have learned Jeanneau is good at hiding switches & outlets - the fridge/freezer drain pump switch hidden under the sink, the aft cabin LED strip lights under the closet doors, the AC outlet in the Forward cabin under the vanity, etc, etc.


Thanks in advance!

On a SunFast 37 is a authomatic thermopar switch at the entrance of the big out hose. Mine did not work, and I replaced it by a manual thermostat.

Mine only comes on when you have the ingnition switch on.

Thanks guys.

Tarik’s is there a switch on yours or is it automatic too? Even with my

I’ll check if mine has a thermostatic switch - thanks for the tip.

SO 439, blower comes on when engine panel is energized.

Found out the hard way that if the fan shorts, it will blow a fuse that controls windlass and thruster. Your configuration may vary.

OK, Thanks guys. I feel dumb 

I started the engine then came back in looked and it is running. It appears to run when engine is running... Duh!

Thanks everyone - smooth sailing!

On my 2015 Jeanneau 41DS there is a small fuse box with a clear covering containing 3 or 5 fuses on the starboard side in the litlle compartment  where the batteries sit on the aft birth.  That fuse is a fuse that also feeds the alternator..
If it goes your alternator will also not produce electricity.  If upgrade your fan...get a higher amp fuse.  I thing the original fuse is 7.5amp.  No thermostat on mine...ignition on...fan goes on.
