Hello,

Has anyone in this section had any experience with the carrier mistral 410 + R22 units?

I have a fault on one located on a farm ( sigh :( ). It has the deisel engine drive disconnected and is connected up to 415v supply. When i found out the phase rotation was wrong, it did fire up although the alternator is seized, but, the evap fans don't run and it seems to switch between cool and heat mode when the stat calls for cooling. The controls all look ok and the temps on the readouts look right. Any ideas?

Also does anyone have any fault diagnosis info or a wiring diagram please.

Thanks, Col.

Gee thats an oldie,i did have a brief connection with the old carriers,im sure i will be corrected,i remember that the altenator definately has to be putting out circa 14volts in order to run the evap fans be it on standby or engine,so if you checkout the altenator brushes & regulator if all ok then maybe it will bring everything else into life,hope this helps some
