Norcold DCOO61R

I called Norcold today, as I have the same issue with "short cycling" (about every 90 seconds in my case). I was told the DC0061R draws 8.0 amps to start the compressor, and 6.5 amps during the rest of the cycle!

Winnebago's choice of NAPA 8240 batteries to power this 12v fridge is ridiculous. You will be lucky to make it through the night when dry camping.

The "short cycling" doesn't change when the shoreline is connected. I have yet to get a good night's sleep due to the loud click that starts and ends each cycle.

It cools just fine. The issue is the noise from short cycling and the draw on the batteries. If anyone has found a solution to the short cycling please let me know!

Seems that these units all have the same operating symptoms.

I think that your only dry camping solution is going to be to convert to the larger 6V batteries or going to Lithium. The Lithium should definitely do the trick, but is pricey. I haven't researched them too much, but most Lithium batteries also require special chargers. So if you go that route look into that before making the leap.

The 8.0A should be an extremely brief startup current (small fraction of a second) and the 6.5A should be during the run portion of the cycle. The off portion will draw 0A, though I should probably check that myself in case there is some other draw in there. Doesnít make sense, but you never know.

So if itís running 50% of the time, thatís equivalent to a 3.25A current draw, round the clock, or 78 Ah per 24 hour period, though I suspect it runs less at night when itís cooler in the vehicle.

You might be able to insulate the thermostat for sound, though there doesnít look to be much room in there. Or thermally insulate the thermocouple to slow its reaction time down. But itís going to run as much as it has to run over time to maintain the temperature difference between inside and outside. About the only way to make it more efficient would be to insulate it further, if thatís possible, or replace it with a more efficient unit.

The duty cycle (On time vs Off time) on mine seems fairly constant over a 24 hr. period, 2 min on - 2 min off. Probably a little longer On time during the heat of the day and shorter during the night.

I don't know how the fridge installation is in your RV, but there is no room for extra insulation in mine. If I could add more, that would be ideal. Obviously the unit was designed to be as compact as possible since it was going into these smaller motorhomes. Unfortunately the insulation density in the enclosure was what suffered from this design decision. As long as it works, guess we'll just have to deal with it. Maybe if enough of these Chinese knockoff compressors fail from excessive cycling, a class action will come about.

I guess Iím not as sensitive to sound as you are. I almost never hear it cycle on or off. Occasionally as Iím going to sleep I will hear it but on mine itís not very loud and certainly does not affect my sleep in any way.

Randy:

I see you have a 2020 View. What model fridge is Winnebago putting in the 2020 models?
