Comfort Master APU: Check oil switch?

I already burned that fan out I put a new one in in top back corner and used a dryer vent, when fan off they close, I had a nasty oil leak and had to remore all the foam under engine

 

heavy duty temp should be able to be picker up at any engine repair place or order online

 

Wiring color coding on mine:
Fuel cylinode Yellow for hot going to starter cylinode
Green to run continues on a on/off switch
Fuel Pump -Red and black off the pump, then turns into Green and black in the harness.
Starter cylinode is yellow wire.

These are the orginal wires that I tied into to go around the computer. Also took out the computer box and control panel.

 

Where was the oil leaking from on yours?

 

side of engine where manufacture has oil filter, comfort master as a block on there with oil lines comming out to remote filter. the seal on the lines was gone.

 

Now I am getting high temp and the fan is not turning on any ideas

 

Mine did the same and I've read that is a very common oil leak on all these comfort master units.
Did you find a gasket or just move the filter back to it's orginal position?

 

Can you tell if the unit is actually getting hot?
Have you had the coolant system recently drained and refilled, so you might have an air pocket in the system causing the senson to be hot but not the complete unit?
Or computer glitch-try disconnecting battery to reset.

Just my two cents but I'm still learning myself.

 

I bet you need to "burp" your system and that should help. I think I might have a couple hoses reversed as mine does not send hot water up to the cab unit. The A/C works fine, but no heat. That's A-OK as I got an Espar that really does the trick.

You have an Espar and an apu unit? Why both?
