I have a problem with my sleeper berth overheating when I have heat mode on in cold weather. I run it at the lowest setting, but it still overheats. To compensate, I leave the curtains open to the cab and have even cracked the windows at times.

It seems I should be able to lower the heat. Any suggestions?

Sleeper Berth:

The portion of the tractor behind the seats which acts as the "living space" for the driver. It generally contains a bed (or bunk beds), cabinets, lights, temperature control knobs, and 12 volt plugs for power.

I have had this issue. I keep it on until the sleeper is warm enough, then turn it off. When I start to feel a chill in the air within the sleeper, turn it back on. There is no variable temperature setting for it. It's designed to use as needed, versus turn it on and leave it on.

APU or an ESPAR heater? Truck idling or engine shutdown?

APU:

Auxiliary Power Unit

On tractor trailers, and APU is a small diesel engine that powers a heat and air conditioning unit while charging the truck's main batteries at the same time. This allows the driver to remain comfortable in the cab and have access to electric power without running the main truck engine.

Having an APU helps save money in fuel costs and saves wear and tear on the main engine, though they tend to be expensive to install and maintain. Therefore only a very small percentage of the trucks on the road today come equipped with an APU.

The bunk heaters Schneider had were no joke. Never used them in super cold. Maybe 20° max.

Now that I'll be in North Dakota I might miss them

APU, no idling beyond 180 seconds

Is there a thermostat type of control anywhere?

I would set the Cold/Heat control dial to center. This will be the Standby Mode, allowing the APU to cycle in order to charge the batteries, should the voltage drop to a set level.

I keep it cold. If too cool, I'll use a blanket.

I have rechargeable fans, and I point one away from the heater, and a gap in the sleeper curtains. I have my heat shield window covers on, and my window curtains pulled, so this allows the front to take SOME of the heat, and the dog water bowl to not freeze, and not roast my behind.

It sounds like a thermostat issue, or the APU needs to reset. I set mine cool and use an extra blanket if I need it. Good luck figuring that out.

Some of us have both an APU and a Webasto bunk heater. The Webasto sucks cause they don't regulate. It is either "on" or "off". So you wake up sweating in the middle of the night... Turn it off then wake up freezing.

2 of my truck had this setup. This one has a Webasto with an actual temp reading. It's better than the one I had in the past.
