Heron air conditioner caravan

They are hard I used a flat blade screwdriver that I bent to slide under to the centre as much as possible ,
the control box hangs off the back of the front panel to remove it, you need to peel the stickers off to find the screws , The box weights too much for the 4 screws that hold the front on and they crack and breakaway on rough roads ,I filled the back around the screws with plastic bond to give it more support .
hope this helps
I got my new front from Air Command on Port Road , Albert Park, SA

I do believe that Dometic have brought them out so what name they are under I dont know

cheers bob

Chris, if you have looked carefully and can't see any screws, then the knobs will almost certainly be a tight push fit.

They can be quite tight to remove, but the best technique is to utilise a small "crowfoot" pry bar, to generate force directly outwards from behind the knobs.

You could also call your local Dometic service agent, and see if you can get any assistance with knob removal information, from their repair dept.

The Dometic site shows only an operating manual for the Heron 2.2 - which does not offer any disassembly advice, only installation advice.
It appears the Heron 3 is now obsolete and has been replaced by the 3Q which utilises touch pressure controls.

Cheers, Ron.
