Dometic Waeco CFX Series Questions & Answers (page 3 of 9)

My fridge freezer does not control to temp setting with compressor running all the time

I have the older 50ltr fridge/freezer every time I plug into 240 volt thru the converter it freezes even in lowest setting and when switched off on fridge, still freezes??

Hi there I brought a 95l cfx and I set in on any setting and it all goes minus does anyone know about this

The fridge is cutting out /wont start when running on 12v. These types of fridge usually have a cut off if the voltage gets below 11.8v but Ive checked the battery voltage and its 12.4v, and its still not working.
I also checked with my other Waeco fridge on the same battery and cable and it does work. what can i do to solve this problem ?

I have the unit set to 2c in the back compartment and -20c in the front it seems to be running constantly switching from one comp to the other with 10min break, is this normal? The ambient temp is 28c and the unit is in the shade all day.

Red light is on the small triangular light below the power light. Neither compartment is cooling. When I click on the ? next to the comment on the mobile app it says “valve faulty”. What does this mean?

My Waeco CFX 28 fridge/freezer does not go below -02 degrees despite being programmed at below -14. the engine is still running an orange light comes on and then a flashing red, then turns green and continues to run but does not fall below -02 degrees. Thanks.Amelia.

Y won’t my Waeco cfx go to desired temp? It stays at -11

Which side of my 60 lit freeze do i use as freezer. Is it close to the motor

My Dometic CFX 50 will no work on 12 volts DC display not coming on and on 120 volts ac it continues to keep running again no display on to minus 50 and won’t shut off. Any ideas?

Hi I have a 75CFX and has been working fine until our last trip where the temperature starting reading higher than what we set it at. For example we had one side set to 4C but on the display it would say it was at 18C. Looked inside and checked the food and it was all frozen. I’ve had a look online and think it has something to do with the thermo sensor, is this right? Would this need to be replaced?

My cfx35 will not work or show signs of power when connected to AC mains I have changed the fuse a tried other cords still nothing.
When I plug into 12/24v DC cigarette lighter port the fridge turns on light is green and begins to cool but eventually after 5 minutes or so it cuts off and light goes orange and stops cooling.
Can anyone tell me what part you think is causing this fault?

where can I find a diagram(manual for the compressor) or youtube vid showing how to replace/remove main pcb board as Ive heard that you can use an air can and some contact cleaner for an easy fix if your fridge only works on emergency override.Otherwise I will replace the main PCB board.
cheers

The 12 volt plug connection is loose within its housing on the fridge, power flicks on and off. Would have thought the housing would have been stronger than what it is. Any advice on repairing please.

What is the sensor in a cfx that turns off the internal lights? I have a dual zone 95 and one side light turns off just before lid is shut the other side is always flashing like the lid has been left open so never turns off.

I have a CFX50 that starts ok in 240 & 12 volt.
Turning it on no green light comes on or Red error light.
Just a solid orange light.
The CFX50 begins cooling and reaches -22 then begins to come down in temp to around +5 then begins cooling again back up to -22.
Have tried it on normal & override positions no difference.
The Digital readout on Control PCB shows unreadable numbers ie: the numbers are not fully displayed.
When pressing the set button, can step thru the sequence and change tof C or Friday and Low Mediterranean High. BUT cannot set the Temperature mode
It is set on +10 but cannot set it.
It freezes the cabinet as said to -21.
I have ordered a new Upper Digital Control PCB to swap out this faulty PCB.
I have remove the Main PCB, disconnected the connector and cleaned with Electronic Spray Cleaner -reassembled AND CFX50 fires up and dies as described an the beginning of my questions.
Iso the PCB the likely cause of the hiccup??
Thank you in advance for your input & suggestion/s.

I have a Waco CFX95 with fridge set at 4 degrees and smaller compartment for freezer at -14 degrees. The freezer only stays at the set temp for 10 mins before the compressor kicks in to cool it down which also takes about 10 mins to get it back to the set temp.

Is this normal?

I have have had this fridge/freezer for a while and never noticed coming on so often. I thought I was getting longer times before it needed to be cooled down again.

How long approximately before the temperature changes in freezer when car turned off, say to go shopping? Is it really necessary to purchase and fit a deep cycle battery if car and fridge off for say 30 minutes?

I have just purchased this fridge/freezer, still have to purchase a deep cycle battery. How does the deep cycle battery connect to car to charge it? And how does it connect to the fridge please?

Running on 12v freezer set at -18 c working fine fridge set at 03c went for a drive 400 kilometres freezer stays on -18 but fridge keeps going up from 8.30 in the morning to 5 pm now on 16 any ideas why fridge going up it’s a cfx 95 first time used on 12v works fine on 240v
