What does it mean when my cf 50, stops and shows; err 2?

Recently purchased a second hand Waeco chest fridge/freezer CF50 as a second/backup fridge on the boat. All was working fine until the fridge refused to start and showed "Err2". According to the user manual (page 23) "Err2" (or any other error message e.g.: "Err1" means that "The device has switched off due to an internal fault." Suggested remedy "This can only be repaired by an authorised repair centre." To be honest that's about as useful as a bicycle to a fish, in the middle of nowhere. So, with the beer getting warmer, the circumstances required a set of screwdrivers, a multimeter and band-aids. I have heard that the thermistor on older units can often be the point of failure. In this case, it also turns out to be the situation. The Thermistor is connected to the upper circuit board located under the buttons to operate the fridge. Not hard to access, 2 Philips heads under the fridge lid, either side of the internal light, then 3 Phillips heads to remove the circuit board from the buttons. The thermistor (only 2 wires) is connected to the circuit board by a small white connected (in my case) to the right of the multi-wire connector. I disconnect the thermistor from the board, hoping an open circuit would at least get the fridge to start without the thermistor (ie 100% resistance), but no. What it did was change the error code from "Err2" to "Err1" (might be useful for anyone tracking down an Err1 problem). So, take the reverse, I shorted the 2 thermistor wires at the circuit board (i.e. no resistance) to see if that would get the fridge to start, but also no, just "Err2" message. Finally, I connected a 10k ohm carbon resistor (cost about $0.85 for a pack of 10) to the thermistor wires and the error code was removed and the fridge started working. The display read 22c, being the perceived temperature at that resistance. Turns out the lower the resistance the higher the perceived temperature. This was not a final solution, because the fridge would run all the time freezing everything. But, by turning the fridge on manually, a couple of hours at a time got us out of a warm beer situation. Hope this helps someone else.

I have a dometic rm 2852 and it keeps blowing the 10 amp glass fuse, what could be causing this? It will not run on electic.

Electrical short circuit, you just have to find it. Look for pinched, trapped or abraded wires. In an RV, vibration from driving is the issue.

Dometic RM2652 Propane Fridge. Can I make my RM2652 Dometic into a manual running fridge on propane?

I have been trying to answer this for over an hour. I moved to a different browser. did you know this model was the subject of a recall?

I have searched extensively for spare but they are all marked out of stock or obsolete. You best bet is to call in a gas refrigeration engineer and see if there is a similar part that can be used. It needs to be something automatic.

Dometic CRE0050 fridge. The orange light flashing

The first thing I would do is check the battery voltage when the fridge is running. The trickle charger may not be enough. The voltage should be between 12.7 volts and 13.2 volts. Solar Trickle Chargers are made for trickle charging a battery that has no load. Also, they only charge during sunlight hours and your fridge is running 24 hours. https://www.google.com/search?q=Dometic+CRE0050+fridge.+The+orange+light+flashing ..

Dometic Refrigerator Model RM 2820 Stopped working

Hi Tom,

If your fridge quit working altogether, check your DC fuses in the fuse box, as well as the back of the fridge under the black plastic cover (3 amp). Though the fridge uses LP and 120vac to cool, it is controlled by 12 volts.

I have a Dometic RM2962 RV Freezer. The freezer door gets stuck only when the unit is turned on and cold. Ever hear of this problem?

Question edited 'Domestic' to 'Dometic'. Question moved from Cars and Trucks to dometic. It could be a few things. Freezers have a heated door frame to stop condensation forming into ice and freezing the door shut. Yours may have failed. The circulation fan inside does create suction. Try spraying the gasket and frame with Jigaloo dry silicone spray.

Does not cool or freeze. Main coolant line is hot from top of burn chamber to almost the fins on top outside of cooling unit and then coolant line is room temperature.

My rv repairman says my cooling unit is blocked. Is there a replacement fridge recommended for my NDM1062 ?

Can my dometic RM 2400 fridge be repaired?

Yes it can be repaired. A refrigeration engineer will find the leak, repair it and re-gas. If it is very old, you might like to consider a new one, because they are more efficient.

On my Dometic RV refrigerator. The freezer works but the main fridge does not?

So if the freezer is working fine but the refrigerator isn't, you probably have airflow problems. In many cases, the freezer moves cool air into the fridge using a diffuser. Sometimes, the diffuser duct gets clogged up with ice, and you can verify this by listening to the evaporator fan.Jun. 13, 2019

I just bought an RV

None of these manual links are good. The only documentation I can find online for the RM2400 is the installation manual. Mine doesn't work. I checked AC power and even ran outside power direct to fridge plug. There is no sound and no cooling. Unlike the other fridges I see online, this one doesn't have a black box or obvious fuses accessible from the bay outside the rv. I'd love to find an actual manual. Nothing works on this fridge and there is nothing online about it. Not even on YouTube. How is that possible?
