Summer fridge problems

When camping in hot weather, is it normal for the refrigerator temperature to rise? My daughter and son in law just got back from boon docking in 90* weather and their brand new Dometic couldn't keep up with the heat. The internal temp rose to 76*. This doesn't sound normal to me. Is it normal? I'm wondering if they don't have enough airflow/venting. Any thoughts?

That's definitely not normal, even in warm weather, and for a new frig. Are there any variable settings that can be made on that particular model? There should be some room inside for air to flow around the food in it, but that seems awfully warm. If they can't get it to perform better by making setting adjustments, I'd have it looked at. A 76-degree frig will not keep food from spoiling.

Did they accidentally turn it off at some point? I only ask that because we have done that. Duh.

It was 106 here today and ours still made ice cubes. Brand new 2013.

No, this is not normal. Sounds like it was not running at all. 76 degrees is not safe for food storage. Next time, if the temperature will not stay below 50 degrees, they should put a bag of ice in the refrigerator to cool their food, or use a cooler, until cause can be determined and corrected.

Suggest that they test refrigerator on 120-volt AC shore power, to verify that the (empty) refrigerator works and will cool down. If refrigerator internal temperature drops to 35-45 degrees on 120-volts AC, it is probably a problem with the propane burner or ignition. Electronic igniter may not be connected to 12 volts DC (battery), burner might not be starting due to clogged orifice or defective igniter, or burner could be blowing out while underway (if they tow with the refrigerator ON), in which case, it may need a wind deflector retrofit.

Post results after testing on shore power, and others will provide more detailed troubleshooting information.

The design of the refrigerator is tasked by high temperature to cool more than 40 degrees from ambient. The freezer may still reach zero while the main cabinet struggles to maintain the forties. A temperature above 50 means something is definitely wrong. The cause can only be revealed by stepping through a diagnostic sequence to pin point the issue they had/have.

We have spent many days in "extreme" heat during our travels and experienced worrisome frig temps which caused me to experiment with various solutions to moving more air. My best solution to date, modifing my Dometic unit by adding four small (2" x 2") computer disk drive fans on a simple aluminum box frame mounted below the the cooling fins at the top of the cabinet back. They draw ~0.2 amps each, are undetectable running, and are wired to a thermocouple switch on the topmost section of the vertical pipe just before the bend downward. They move enough air to maintain 41° or below when the temperature outside reaches 100 depending on the amount and angle of the sun on the trailer.

I use four of this style fan (covering the full length of the fins) mounted approximately 1/2" below the condenser fins for a concentrated, targeted air flow avoiding the need for a shroud or the bigger boost fans so many RV sites promote:

SeeMore, very nicely done -- looks like a professional installation!

So, when will these be available commercially? Are you offering discounts to AirForums members?

Just kidding, but this looks as good as any kits being sold. -- Very good job!

First make sure the space behind the frig is unobstructed for airflow. Make sure the space is venting properly to the roof vent. There should be a sealed partition at the top of the frig to prevent venting into living space over the frig.

Additionally as I did you could install a solar fan at the top of the frig roof vent cover.

I think the freezer temp was in the 60's. Not positive but the icecream was cream

Handy hint from hurricane country, where power outages at home are part and parcel of every tropical storm…

In your freezer, freeze an ice tray, and place a dime on top of one of the ice cubes. As long as that coin stays on top, that means your freezer has never unfrozen. But of the coin is ever inside the ice cube, that means the ice has thawed and refrozen, and all of the food inside your unit will need to be thrown out.

Handy hint, Protag. I'm going to write that down.

The "Amish" rebuilder for the refer innards offers fans that sit on the warm air exit vent of the TTs. I wonder which method is better? By the way, I love your fabricating!

FYI, he also offers a fan that clips onto the fins that are inside the refer, to keep cooler air circulating.

the freezer cools quickly compared to the fridge. in either case, opening up the door warms things enough that it can take almost an hour to return to the pre-opened temps.

since both compartments were warm, i'd start with the basics.
if it works ok now then you know it isn't dead.
verify that the fridge was set to gas or auto and that the gas lights and stays lit.
verify that there is gas in the tanks and that both are open.
