Class B Pleasure Way. In hot weather, on propane or battery power, the frig won't keep up. It does fine plugged in at a campground but I'm usually in a parking lot during the day. I've been leaving it on propane, but 60 Degrees certainly won't keep food safe. Will Solar panels be enough to do it? Is there a thread anyone can suggest to recommend the best type and connection? Prefer to have panels be mounted permanently vs. temporary set up on the ground because of theft potential. Thanks all in advance.

Fridge should operate with similar performance on gas or electric.

So, your fridge works ok on 120vac then. You'd need an inverter to supply that, plus about 25amps of solar feeding the batts.

And how is solar going to help when the sun isn't shining full tilt? [emoticon] The correct solution is to figure out why the fridge isn't operating on gas as it should. [emoticon]

On propane at Stovepipe Wells with temp at 105F in March my fridge did great on propane even during the one to two hours in the sun. Add fans inside and behind. Have your fridge serviced. Getting 25 amp hours from solar on a B will be a challenge...roof real estate...five 100 watt panels.

The answer is no.
If you can't cool when running off 120V or when running on propane with a good 12V source, solar isn't going to do anything for the fridge.
All solar does is keep the battery up.

Is the battery thats running the fridge going dead ? If not, fridge should work just as good on propane as electric. If so, then solar will help the battery

Thanks all. The 'experts' have checked the frig and supposedly there is nothing wrong with it. It is original equipment on a 2000 model Pleasure Way. 2oldman, if the panels are connected to the batteries, wouldn't I have the identical issue? It seems like there isn't enough power coming from the batteries (which are pretty new) Please forgive my 'newness', but the frig has 3 settings. I use AC for when I am plugged in, DC for batteries and gas-gas. If I have solar panels, can I use the AC connection instead of DC, or is there a way to plug the AC into the inverter for panels and get more power?

Confusion here... Please clarify.

Something is definitely wrong with it. At 18 years maybe it's time to replace.

You would need so huge solar to run the absorption fridge on 120vac or 12vdc direct. The only practical way is to use propane. 12v just operates the control board and propane igniter. Have you looked to see the actual flame?

Although put a voltmeter on the battery to make sure you have 12.0+ volts and then check the fridge control board is getting similar voltage. If the propane igniter is working you probably have enough battery power.

You could try a new control board. People seem to like the Dinosaur brand.
