Webasto Bunk Heater Auxillary Heater Issues

Does anyone have a list of codes for the older bunk model? I just replaced mine and it won't ignite. Same problem as other heater. Both are older models.

 

AT2000 blink code list
F 01 No start (after 2 attempts)
F 02 Flame out (at least >5)
F 03 Voltage too low or too high
F 04 Premature flame detection
F 05 Flame sensor open or short circuit
F 06 Temperature sensor open or short circuit
F 07 Dosing pump open or short circuit
F 08 Fan motor open or short circuit or
wrong speed
F 09 Glow plug open or short circuit
F 10 Overheating

More detailed info with freeze frames is available with ThermoTest software (free) + simple K-L adapter.

 

look at the green light if itblinks 10 times just take of the intake hose off.it will work with no problem.it does it because it overheats.when you take off intake hose problem will be resolved

 

if it is warm in cab heater may stop and restart later.

 

How do I set the #### thing to shut off on its own? Only thing that I have that controls the unit is the temperature knob in the sleeper. However even when set at less than a half point it stays on until I manually shut it off. Also the fan is working the whole time so after a few hours it tends to drain my batteries. It was in the truck when I bought it so I have no idea if this how it normally operates or is it faulty.

 

if it is warm in sleeper air heater shuts off, but air heater blower keeps running at low speed, and when temperature goes down it restarts.

Yepm it drain batteries.

 

If it is draining your batteries then you need to have your batteries tested. I can run mine for a week and still start my truck .

 

the good thing is opti idle, icon and other stuff that starts engine with low batteries. But usually no this systems are installed and battery protection systems wake drivers up to start!

 

I have a 2006 webasto 2000 s air top bunk heater giving off a code 8 bad fan motor. Having trouble finding this part. Been looking at websites for 2 weeks. Any ideas?

 

granted mine was an Espar.

Likely a dealer only item.
