Dometic CFX3 Recall info thread

Hi Everyone,

As you may have heard through our dealers and forum members, we recently issued a recall notice for CFX3 coolers. We've attached a copy of the recall letter that you should receive if you've registered your CFX3 cooler.

The short version:
If you have your cooler plugged into AC and DC at the same time, the DC supply is switched off, and you have other DC appliances connected, a protection device in the cooler can fail and feed 28V into the DC circuit. This can then overload the other DC devices on the circuit. The resolution is to attach an additional warning sticker to your cooler. There is no need to return your cooler unless you want to due to the recall. We're happy to honor these requests.


The longer version:
If (1) you have a vehicle with both AC and DC circuits and (2) a CFX3 unit is connected to both onboard 120VAC and 12VDC circuits/sockets at the same time and (3) the 12VDC supply is switched off with additional 12VDC device in line with the CFX3 in the “ON" position, under these circumstances a protection device in the CFX3 unit can fail and allow the AC/DC power supply to back feed 28V through the CFX3 to some or all the other DC appliances (such as AC, water pump, lights, furnace, etc.) that are connected to the 12VDC system. DC appliances on the same DC circuit may therefore fail from a voltage overload.

Although no fire has been reported or observed and is extremely unlikely, the voltage overload may cause electrical damage and local charring damage to such appliances and immediate surrounding materials.

Potential use cases, although rare, which can lead to this failure can happen when the CFX3 is connected to BOTH AC AND DC power and:

1. While connected to AC power, something causes the master fuse on the DC circuit of the vehicle to trip, removing DC power from the DC circuit; or

2. While connected to AC power, the user chooses to turn off the vehicle’s 12VDC power system; or

3. While the vehicle’s 12VDC power system is turned off, the user turns on the vehicle’s generator or inverter.


We've attached a copy of the recall letter that has/will be going out to all registered owners. If you have questions about the recall give us a call or email at the following:
