93 Starcraft Refrigerator Questions

[TBrum]

Hello,

I just purchased my first pop up camper. It is a 1993 Starcraft Galaxy 1224. When opening the side panel to the refrigerator controls, I see there is a 12 volt on/off switch and what looks like controls for using the fridge via propane. The challenge is that I had the camper plugged into 120 yesterday and the fridge did not seem to cool at all. In fact, it seemed downright warm. It was an 85 degree day. Also, I do not currently have a battery hooked up to the pop up and I don't know if that has something to do with it? Looking through my manual was no help. So, I figured I would take to the internet and see if anyone has some insight into the controls of this particular unit. Any help you can give would be appreciate. Pic enclosed.

I'd guess the OP's fridge is a Dometic 2150 / 2190 / 2201 series, predecessor to the current RM2193 which is still being manufactured to this day. This diagnostic manual should help.

the 2150 is not 120vAC. Might operate it on 12v via the converter if wired that way (doubtful).
gas would be the best after a good burner et al cleaning.

The 2201 is - pretty difficult for any of us to help the OP until he identifies just which model of fridge this is.

No Fridge Manual. Dometic RM2190 is the model.

No Fridge Manual.

Well you have one now at the link I posted earlier.

Dometic RM2190 is the model.

So the RM2190 has no 120 vac capability, just propane or 12 vdc, the latter of which would normally be supplied by the tongue mounted battery. With the trailer plugged into a 120 vac source the converter should alternately be supplying 12 vdc to the fridge. Your best bet is to start tracing using a voltmeter to determine if the fridge is in fact receiving 12 vdc. Keep in mind though you only use the 12 vdc mode when you're towing, prefer to not use gas at that time, and have an active charge line feeding the trailer from the TV, otherwise use the gas mode only while towing and camping.

Thanks guys! So helpful! Nube question: Am I able to light a propane for the refrigerator with the pop up closed? And the propane fridge can run the whole time we're camping?

That`s why your camper is equipped with a gas absorption fridge rather than a 120 vac compressor fridge. Just make sure you understand the need for the camper and therefore the fridge to be relatively level when running this fridge.

Thanks! So helpful, guys.
