Compressor refrigerator in Sprinter motorhomes?

It appears many of the new Winnebago Sprinter based motorhomes are using a compressor refrigerator. For those who have this type of refrigerator, how noisy are they in a small motorhome? In my case with our 2016 Itasca 24J the refrigerator is at the foot of the bed. Also how about dry camping? Will one 100 watt solar panel and two Trojan T105 batteries keep up with the power demands? All input and advice is appreciated.

I am just changing out my Dometic 8555 for a compressor Refrigerator so I'll have to update this after I have time to use it. It should be about the same draw or possiblity less on my batteries since I had to run so many extra fans with my Dometic to aide it in cooling. It drew 10+amps, this compressor model should only draw about 6 amp when compressor is running. I'm installing an Isotherm Cruise 219 with 7.8cuft.

It's quieter than the engine and louder than silence. Actually, it's quiet when the compressor isn't running, and barely audible when it is.

I have the stock Napa FLA batteries and they seem to be able to handle the load, but it's probably a borderline situation, and depends on all the variables being in sync. When they die, I'm going lithium.

You can never have enough battery capacity and solar charging. I added a 3rd panel for a total of 300W up top. I'm sure it helps replenish what the fridge and the rest of it pull out of the batteries.

Went from a diesel pusher to a Navion 24D 6 months ago. One of the things I REALLY like about the coach is the compressor fridge. Do not have to worry about being perfectly level - very quiet operation - starts up fast (no overnight startup with fridge fans) - works off solar - no extra vent hole in the roof. Best thing is works like your home fridge... hard ice cream, cold beers... definite improvement IMO over the old fridges...

Well it took me 3 long days for this remodel and I am very pleased so far. I did not have time to take any pictures but it was a very challenging DIY remodel. I worked furiously when I got the Refrigerator last week to get this done since we had to leave for Elkhart on Monday to get the new Levelers. I've only been using the Refrigerator for 2 days but already I love it. As you can see from my outside temp gauge, which has the sun on it and reads 119.4 degrees, that the old Dometic would be super challenged to cool to 40 degrees or less. This Isotherm Cruise 219 2 way AC/DC compressor Refrigerator is only on setting 4 of 7 and is -6 degrees F in the freezer and 35-38 (interior and door) in the refrigerator. It is so nice just to set it and forget it, no more adding ice and worrying. The temperature never changes whether on battery or shore power. It uses between 2-7amps versus the 10+ the old Dometic and all its cooling fans, temp gauges and temperature controller used. I took in the Refrigerator exterior compartment and sealed the outside wall and added Reflectix insulation. Even with the sun beating on it my Temp gun only registered 82-85 degrees on the inside wall now. The Refrigerator comes with a fan to exhaust its compressor area at the bottom left corner and then I added one 120mm fan from my old setup to help move air from behind the Refrigerator and to ventilate the microwave compartment. There is about a 4 inch space that is open from the floor to ceiling behind the Refrigerator/microwave so that should allow for good air exchange from the air conditioned room to the back of this new space. The extra fan is located just behind the left side of the microwave. To pull air from the 4 inch space and blow it over the back and left side of the microwave, where it's exhaust area is. The Toshiba microwave, at 900w, works much better than the old Hotpoint and is the perfect size for how we use microwaves. I shed 52lbs between the old and new. The Dometic weighed 99lbs versus 75lbs for the Isotherm and the Hotpoint weighed 55lbs versus the Toshiba at 28lbs. Nice added benefit! The Isotherm Cruise 219 is slightly larger at 7.75 cuft (6.3cuft Refrigerator and 1.45cuft freezer), than the Dometic, which is nice. It is so nice to have an ice bucket with ice in free moving cubes versus a melted frozen blob of ice cubes. And to be able to actually use the ice versus just carrying it to help with cooling. I wish I would have done this along time ago, but I wanted to try and make what we paid a lot of money for work the way it is supposed to. I did my best and got the Dometic working reasonably well but I worried about it constantly. While we were driving today everytime I opened the Refrigerator the temperature gauge on the door was constant at 38 degrees. Love it! I guess I'll have to keep my Unity for a few more years.

The VITA and Porta both come with the DANBY compressor refrigerator (110volt only)
Mine died right after I bought motorhome, found a bad overprotection fuse, replaced and all is well, however the inverter had died also, hmmm maybe a problem with inverter caused refrigerator problem.

My Galleria came with the Norcold DE 0061, which has a separate top freezer. They also make a smaller one, DE 0041, with just a single door and the freezer inside, like a cube type dorm fridge.

It's mounted behind the driver's seat, and we sleep in the back. I can't really hear it run, though my hearing is less than what it used to be. The thermostat is all I hear, as it has a pretty good 'click' when it kicks on or off.

The specs say it draws 0.4A on 120V AC power, and 3.2A on 12VDC (has two sets of power leads). It seems to run less than half the time, though I don't know how much less. That's with the interior at or around room temperature. Presumably, it will run more if it's hot inside and less when cool.

So far I'm very happy with it. Freezer is very cold and keeps frozen food solid, and refrigerator section makes things like bottled water and milk "feel" to the touch about what we're used to, using the middle value of the temperature adjustment dial. I should probably stick a couple of thermometers in there to see what exactly it's doing, but it's off for the season and snowed under, so that's not happening soon.

Assuming a steady running current of 3.2A on battery power, and a 40% duty-cycle including cooler nights and hotter days, that's 31Ah per day. My 300W solar panels should be able to output 150W in the real world on a reasonably sunny day, which would be something like 70Ah over the course of 6 hours.

Someone can/should correct me on anything I've done wrong there, as this is my first foray into solar power. But at first glance, it looks like solar should have no trouble providing enough to run that fridge (only).

Our 2019 View 24V was equipped with a Norcold DE 0061. It maintains good internal temps., but its cycle rate is 50% (1 min. on/1 min. off) which seems too frequent to me. It's as if there is not adequate insulation in the box. The thermostat will change the temps. but not the frequent cycle rate. Just concerned that the compressor won't hold up. Tried adding a fan in the main compartment to move the air, but that didn't seem to have any positive effect.

Any other owners of this fridge have similar cycle rates?

I have that exact same issue with my DE0061. A new thermostat is like $38 or so, but if it's common to the design, it probably won't solve it.

But if there is a probe somewhere inside that's connected to the actual thermostat, insulating it will slow down (but not stop, of course) the temperature change it experiences, and should therefore extend both run time and off time intervals while not affecting the average internal temperature.

I'd pull mine apart, but I'm on a road trip, and DW wouldn't appreciate it.

I contacted Thetford (Norcold) regarding the rapid cycle rate and the customer service guy indicated that the cycle rate was acceptable. My guess is that he doesn't own one . Normally a designer will build in some hysteresis into a sensing circuit. It allows the system to travel a little above and below the set point before taking action. This thing doesn't appear to have that ability, or if it does, it's too narrow a window. Seems like the short cycling would make it real hard on the battery bank, if dry camping.



In a follow up email, I told him that I also noticed that the compressor seeded to change speed during the cooling cycle and asked about that. Hopefully he'll respond today.


Other than that the unit works well at maintaining temps. Maybe the box just needs more insulation.

Smile 12 volt AC

We have 35000 miles with the 12 volt compressor, love it, noise is very tolerable. Have to be quiet to hear it. I did upgrade my batteries to the largest that well fit in compartment on top of pan. 2x6 will fill the tray perfectly. I happened to have two new batteries for my trolling motor and I swapped . Minor rework on battery brackets. We very seldom boon dock on batteries for more than two days but solar panels seem to maintain very well. Had minor problem with compressor cooling fan and thermostat. Warranty took care of it no questions. Freezes ice and cools drinks in bottom very fast. Operates very efficient when unlevel

Original poster here ... Thanks for all the real world experiences with the compressor refrigerators in Spinter based motorhomes. Since most of my camping is off the grid for a week or more at a time it seems best for me to stick with a traditional propane/12v/120v refrigerator. No doubt with enough expense of extra solar panels and lithium house batteries it would work but the extra cost doesn't justify trading up for a newer model motorhome. Again, thanks to all for sharing.

Camper Ken - I think that staying with a standard evaporation refrigerator would be best, especially if you do a lot of extended off grid camping. So far we really like the compressor unit, but I think that you would see more generator time, even with solar panels.


Full Dose - What was the problem that you experienced with the thermostat & fan? Also did your unit short cycle like mine and others, (1 min. on/1 min. off)?

12 volt compressor

The thermostat on our refrigerator would satisfy to below zero in freezer and not cycle on again until the freezer got to 40 degrees. Once I replaced the thermostat every thing has been good. I havenít noticed ours short cycling. Next outing I will pay closer attention.
