Dometic propane fridge control photo needed

[Pntyrmvr]

Hi,

I've smeared the lettering on the gas temperature control knob on my 30 year old Dometic 2190 propane fridge. Also the control knob for the 12 volt temperature setting is missing.

I imagine every Dometic from way back uses the same knobs.

I need a clear photo of two things:

1- the gas temperature control knob

2- the 12 volt temperature control knob

Thank you.

I'll add photos of the existing gas knob and the missing 12 volt temperature control knob.

I have no idea which way these things adjust and the old unit takes so long to react to adjustments as the day's temps vary it would just be easier with a photo or two.

Thanks.

One of these might be of help...No pictures, but recommended settings and how it works....For 12v, maybe try the middle+ and measure with a temp sensor...Gas start with 4...12v is incredibly inefficient...

Thank you.

Tested it. 10 amp draw to run the 12 volt side. Ouch.
