Default Roadtrek refrigerator question

I’m loving my “bought used” 2006 Roadtrek 190 Popular. But the refrigerator won’t get above 50. My local repair says a new Dometic would be around 1,000.00 once I paid freight. Anyone know of a less expensive option for a frog?

I assume you mean it won't go "below" 50°. There have been reports of people "burping" their absorbtion refrigerator. You can find out how on you tube. Your results may vary.

12 hours ain't enough. Try two days and put the thermometer in the freezer and see what it does, then get back to us. PPL outta Houston will sell you one but you have to put it in. You can check their price.

.

10 yrs old fridge?

Yes it needs burping.


These fridges can go 20 yrs or more.
You can check the burner to make sure it is not rusted.
Check the flute to make sure it is clear.
Check the vent.
If the ammonia circuit is good, the fridge can go on forever.

Make sure the fridge is level. Most efficient on propane, then 110volts.

It may take 24 hours to really cool down.

BBQ: Is there any evidence that "Burping" actually does anything? Is it something that is outlined in the service manual by the OEM? Why does a fridge need "Burping"?

Lots of instruction video on youtube; they can explain it better than I can.

This is black magic; you might not find this in the service manual. This esoteric knowledge is a result of years of user experience, and a true understanding of the inner workings of an absorption circuit.

All I can add is this: years ago we bought a used Class C whose refrig just wouldn't cool. I took it to a little local shop and they "burped" it. It then worked great for the many remaining years we owned it.
