Comfort Pro Apu Issues (solved)

No they seem about the same. I have the same 3 cyl in my kubota tractor that's 20 years old it's been a real workhorse.

The difference between the two cylinder and three cylinder kubota diesel motors is very substantial in terms of vibration and noise. The 3cyl is a far better motor overall , so much smoother and quieter.

Matter of fact I'm replacing the glow plugs on the Carrier APU today. First set and it's still on the original Serpentine belt at 5300 hours, which still looks find but for $25 , it's getting changed as well.

 

Harbor freight have a universal belt , comes with links and it s red color. They don t sell belt anymore .

 

When I turn my apu on it cranks up but then once it's running it stays running can't get any AC or heat to come on and start blowing air?? What's going on?

 

My apu comes on but can't get AC or Heat to come on and blow air.

 

Do you get 120 VAC power?
It’s not really possible to pinpoint the issue without getting hands-on, and it’s been several years since I’ve dealt with these. Do you get any error messages when you try to set the mode or temperature?

 

Probably low voltage and needs s new capacitor.
