A/C Repair
« on: August 22, 2017, 09:22:57 AM »
Hi I have a used AC unit off of a Komfort 5th wheel.  I belive its a delco.  I have had power and controller hooked up and the compressor runs great.  Gets hot where it is supposed to and gets cold where it should.  I can hook up direct power to the can motor and it runs very smooth, but i cant get the two to talk to each other.  Im thinking a relay but looking for other suggestions...

Is this an RV roof a/c unit? I don't think Delco ever made anything like that. Maybe Dometic or Coleman Mach? Delco built engine driven a/c units for vehicles, not trailers.

What sort of controller?  Thermostat? Please explain a bit more.

Sorry about that it is a Dometic roof mount.  It is a wall mount thermostat.  The heat lines are not hooked up at this time.  Has fan auto/on/off, and all the normal options.
