Thermoking evolution ran out of oil.

I’m assuming you reset the apu? If you haven’t, I would try that first.

 

Most of the time if an APU happens to stop the whole unit is out. Find the reset and press it. Most trucks I had that reset was under the bunk.

 

Unless you simply haven’t checked the oil in months and it slowly burned through it all, and assuming we’re talking about a newer unit, you better also check for oil leaks if you ever get it started.

If it leaked, I’d suspect you’d be able to see evidence of it still. If it burned through a quart in a relatively short time, something is wrong in that scenario, too. Do you run it continuously or in some sort of auto mode?

I’ve heard of them being improperly set up and they’ll run 24/7 practically no matter if the truck is parked or running down the road. That would lead to seriously shortening it’s useful life.

 

My low hour carrier APU will require about a half quart to bring back to full after about 2 months of running during most breaks on various start/stop modes (heat, cool, and battery maintenance)

They’re easy to overfill. Not sure how detrimental that might be.

 

Do you know the oil capacity on the apu.
