The Dometic CFX3 Mega Thread

I am using an EF River 2 Pro as the primary with a River Pro as a backup. I am not even sure of a battery pack that has a DC5521 port that will support 8A but am looking at the usual suspects. Any ideas you might have would be greatly appreciated!

 

@Naveronski Thanks

 

Yeah. Someone posted that Jackery said "Don't leave it plugged in" or such.
Replacement was out of stock.

 

@#$% the Jackery did that? Hope they eventually swapped it out! Funny if you're not supposed to leave it plugged in then how to you keep the cooler powered

 

Guys, I have figured out warning code 43 fixed. The display (Dometic 4450021433 HMI and Connectivity Display Module for CFX3) is defective and need to be replace. When the display module arrive you need to download 619 config appz to set up your new display with your CFX3. All you need to do is follow the instruction within the appz.

Yes, this is for Dometic CFX3. I have a 95DZ with warning code 43 (communication error). It's should work for other CFX3 model too.

 

Jackery sent a new cord.
Customer service is outstanding.

 

Is your CFX3 still under warranty? If so, have you been able to secure your replacement parts? If not, send me a private message here on TW and I'll get you connected with someone that can assist

I bought my Dometic CFX3 DZ95 on Ebay brand new in the box on Back Friday for $200 less. For that reason, Dometic denied my warranty. They said that they have no way of varifying I am the original owner. Bummer. Anway, the unit is only about 2 years old. I know the compressor is in great shape. I have had the problem with Wifi and Bluetooth for a while before this and I had changed the controller module by the compressor already (DFC20AD) right after I came back from vacation and that got the the unit to work again but on default setting. Freezer @ 0 degree / 55 degree for the other compartment. I've also changed the thermistors too. And just got my display part last week from Boat & RV Accessories for $93.55. I am so glad my unit works again. I am able to set and control everything from the app on the phone.

Note. When ever you're not using the unit disconnect it completely from both power supply (12volts / 110 watts). I had mine on a semi tractor. Clean the inside, leave the lids open and press the OFF button and came back dead with warning code 43 after 2 months. I had one Northstar agm31 and 4 regular batteries and can't even jump start my EU3000is to charge the system up. Everything was completely drained. No alarm, no camera nothing. I had to pull out my EU3000I to charge the system up. And I had to dump the 4 regular acid batteries and upgraded my power supply to all AGM31 and a BougerRV 200w solar panel.

The unit some how restart itself with the lids open after I left for a vacation. That's the reason both of my display & DFC2AD modules both died. Guys, if you use the unit on a regular basis every day. Clean up the fan area as your to do list every 6 months. I pulled the fan out clogged with dust.
