A Happy Camper Review by
I bought this fridge to replace a similar product that was in my Hi-ace camper van when I bought it, but wasn't working. This one fit the space exactly and is very quite. Love the fact that this one can be plugged into 240v power if power is available. Interior light, so easy to see inside. Plenty of room for my fresh produce and beverages etc.

Great quiet little fridge Review by
This little unit fits nicely under the bench in our 14' Franklin. Big enough to hold the essentials without taking up a bunch of space. Also extremely quiet, I never noticed any sound coming from the fridge when trying to sleep. Very happy.

Great fridge! Review by
We love this fridge! We had a bigger version on our old campervan and bought this one to fit our Delica. It uses less power but it still has heaps of space. The option of removing the bottom drawer is very handy, and even the freezer if you need space. Definitely a great choice!

Awesome even better than the old model Review by
Stoked again. Does everything I need in the truck I use it everyday, freezer is even better than the last model. Sizes are exactly as detailed, I run mine thru a small inverter and have had no problems. Well done waeco.

Product Q&A

Ask Us a Question
  • The manual refers to a red/black cable to connect to the battery. But all I can find is a white/black cable?

    Yes it is a white/black cable. Simply follow the cable back to the compressor model to see which is labelled as negative and which is positive.

    For any Waeco technical support simply call 1800 212 121. Thanks!

  • How often do I need to service my Dometic RV/Caravan appliances?

    Dometic recommend servicing their gas appliances on a yearly basis, even if the vehicle has not been used. Additionally, bear in mind that insects can built nests in the gas appliances which will cause the appliances to stop working. It can also cause potentially dangerous scenarios.

    For other appliances, such as refrigerators and air conditioners, to ensure the appliances to work efficiently and last longer it is recommended to clean the condenser.

  • Hi, what compressor is used in the Waeco CoolMatic CR fridges?

    Hi Jake;  the Waeco CoolMatic CR range of fridges use a Secop compressor. 

    In Summer 2016, Dometic Waeco will release a newer version of these models known as the Waeco CoolMatic CRX range, and these fridges use a Waeco compressor. These newer models are available in the same size, and offer a couple of additional benefits such as removable freezer compartment, slightly reduced noise, and slightly better energy efficiency.  


  • The manual for the latest CRX models mentions that you need a MPS 35 Rectifier (listed as an accessory) if you plan on connecting to 12v and 240v, is this correct and where are they available from and the cost?

    Hi James, great question. The latest version of the Dometic CRX Manuals do make reference to an MPS Rectifier as an accessory... which is a little confusing because you definitely do NOT need this rectifier to run any of the Dometic CRX models on AC (240 Volt) mains power. All of the Dometic CRX models can be operated directly on a 12/24V DC or 240V AC power source. 

    The reason it is mentioned in the manual is that it is a universal manual, intended for a world wide audience...and there are some versions of the CRX models sold in other parts of the world (outside Australia) which are slightly different than the models in Australia. 

    In summary;  the latest versions of the Dometic Waeco CRX Compressor RV Fridges that we sell here in Australia do NOT need any sort of adaptor or rectifier to be able to run on either DC or AC power. Many thanks. 


  • Can you confirm which Dometic Waeco CRX models have the LAC (Low Ambient Control) (winter kit) fitted as standard? The CRX product manual states only CRX 110 & 140 models have this fitted.

    Hi there, the Winter Kit/LAC function is built into the Dometic Waeco CRX110 & CRX140 models only. These two CRX models have a permanent freezer (the 3 smaller CRX models have a removeable freezer). The LAC winter mode ensures optimum operation at ambient temperature of below 16°C.

    There is no LAC function inbuilt to the CRX80/65/50 models...nor can a 'winter kit' be fitted to these 3 smaller models.

    The Dometic CRX units are tropical rated fridges, which the specified operating temperature is 18-43°C. They will still maintain a normal fridge compartment temperature when the ambient is lower than 18°C, but will cycle off for longer periods, and depending on stock level the freezer temp may rise...Hint: if the freezer is stocked fully with dense products, then the temp will hold over for longer in the off cycle. 

    Many thanks

  • With regards to the Dometic Waeco Upright fridge models. Can I choose which side of the door the hinge goes on?


    Some models require the customer to choose a hinge position prior to delivery. You will notice a Left Or Right Hand hinge option on the product page.

    With all the other models you will be supplied with a hinge conversion kit. The door will come with the hinge on the right hand side as standard. You can easily change it over using the kit. Feel free to view the Installation instructions on the product page for each model.

  • Does the fridge auto select between 12v/24v?

    Hi - Yes it does!

    Thank you :)

  • HiCan I order this fridge with the door opening the other direction of what is shown in the photo?So hinges on the left side. Thanks

    Hi Melita,

    The CRX range of fridges come with the ability to alternate the hinge location.

    This can be completed once the fridge has been received at your end.

  • I was told the Waeco CRX has removable freezer compartments- is that correct for all models?

    Hi Sam, in the CRX range, only the CRX50, CRX65, and the CRX80 models have a removable freezer compartment. 

    The two larger models in the ranf (CRX110 and CRX1140) do not have a removable freezer. Thanks

  • Is the frame (Standard or Flush frame) required as part of installing the CRX fridge?

    Hi there, the answer is No. The frame is not required as part of the install. The frame is an option to help with presentation within your cabinetry; it tidies up the fridge perimeter in either a flush style or standard style (fridge door sits out proud). So the frame is just an option. 

    The fridge is fixed to your vehicle typically by the screw holes in the floor and there are side screw holes as well. Thanks.   


  • We currently have an old Waeco CR model refrigerator in our camper. How is the performance and offering of the newer CRX models in comparison?

    Hi there, the latest versions of the Dometic Waeco Compressor fridge-freezers are known as the 'CRX' range, which replace the old CR models.  The new CRX range has the same physical dimensions as the previous CR models, but slightly improved performance including;  greater temperature control, reduced noise, and better energy efficiency. More specifically:

    • Custom built Dometic Waeco compressor (Variable speed compressor) replaces Secop (Danfoss) compressor from previous models
    • Improvement in energy consumption (-10% to -30%)
    • Tropical rated:  designed and rated to work up to 43 degrees C
    • Interior Temperature Range:  Freezer -15 °C to -5 °C, Fresh: 3 °C to 12 °C, rapid cooling (without freezer): min. -6 °C ± 2 °C
    Our staff use them in their personal RV's and our customers have provided excellent feedback. We would not hesitate in recommending them. Many thanks. 
  • Are the Waeco CRX Fridges Tropical Rated?

    Hi there, yes is the answer. The Waeco CoolMatic CRX range is classified as having a Climatic Class of 'T'. 

    Fridges graded 'T' (which stands for Tropical) are designed and rated to work up to 43 degrees C. Thanks.

  • my boat is 12v - 110volt, is this compatable?

    Hi There,

    The CRX50 should be compatible with your boat.

    The technical data in the manual states the following:

    Voltage: 12 Vg or 24 Vg
                  100 – 240 Vw (ACDC models only)

    Fortunately we only sell the ACDC models.

  • Can this CRX model be run as fridge only with the freezer compartment removed?

    Hi Ty, yes freezer compartment of the CRX50, CRX65 and CRX80 can be removed. This means you can choose between having: a fridge, freezer or both at the same time! Thank you.

  • Will this fridge tolerate operating in a semi-closed space? E.g. Mounted to the side wall of the cockipit on a boat.

    Hi, it is advised that there is sufficient ventilation around the refrigerator, especially behind it near the cooling unit. 

    The fridge does not come with mounting brackets. However, there are four screw holes inside the base of the fridge that allows you to fix the fridge to the floor.

    Hope that helps - cheers, Steve

  • Is the price the same for Left Hand hinge? How do I order?

    Hi, the Dometic Waeco CRX range of upright RV fridges come with variable door mounts & hinges, so they can either be left hand hinge, or right hand hinge. They come delivered right hinged as standard, but you can easily change them over to a left hand hinge. So there is no price difference when it comes to hinge side, it is the same unit and you can choose what side hinge you want to use. 

    In terms of placing an order, you can either add it to the shopping cart on the website, and then fill in your delivery and payment details online...or, you can call us on 1300 400 122 and place an order over the phone with our team. Many thanks :)

  • At what voltage will the fridge shut down?

    Hi, The refrigerator can be operated with a 12 V or a 24 V DC voltage supply.  To protect the battery, the refrigerator switches off automatically if the voltage is insufficient:

    12V cut-off voltage:  10.4 Volts

    24V cut-off voltage:  22.8 Volts

  • ** Dometic Troubleshooting Tip ** - Try the fridge on 240 V AC mains power

    If it works normally on 240 v mains power, then the problem is almost certainly with your vehicle wiring, not the fridge.

  • ** Dometic Troubleshooting Tip ** - Is the Fuse In the Cable Blown?

    There is a fuse in the plug of most Dometic fridge cables.  The fuse can be accessed by removing the single screw.  Replace the fuse (with the same rating as original fuse) and reassemble.  This is not a common problem, but it can happen and should be the firwt thing to check.

  • ** Dometic Troubleshooting Tip ** - Have you cut or extended the cable supplied?

    Unless you do this correctly you will prevent your fridge from getting enough voltage to operate correctly.  The cable provided is the minimum thickness required for that length.
