Default Coolbox not cooling

Hello All! We are on trip #2 in our new (to us) Westy. This time we are at Fort Flagler State Park in Washington. On trip #1 we had a suspicion that our coolbox was not cooling and after purchasing a fridge thermometer, we can now confirm this. We have tried adjusting the coolbox temp using the central control panel but this seems to have no effect on the temp of the coolbox. No matter what temp we adjust it to, the coolbox holds steady at a balmy 50 degrees. We can hear something running under the coolbox so the motor or whatever it is seems to be functioning. Does anyone have any suggestions on how to troubleshoot or fix? pictures and a step by step would be ideal. We'll post back on how we fixed it.

Thanks in advance!

1. Coolbox is on? Power on/off switch is on computer console--snowflake button and power button together. Snowflake icon should be on central computer console.

2. Temp set.

3. Repair Manual. In the Repair Manual, there should be a section on the fridge where you push various buttons on the central computer console to test the fridge.

4. Noise. Just double-checking noise is from under the fridge and not the air conditioning converter fans under closet (operate when plugged in or on generator; can turn off those fans by turning off farthest right circuit breaker).

5. Expectations. The fridge can take a lot of time to get to a cool temp. The Owners Manual gives some suggested length of time (many hours) for coolbox to be on before taking off, and for stuff to be cold when putting into fridge.

If you just turn fridge on and start driving for a short trip, may not be enough time for coolbox to cool stuff down.

Once operating for awhile, coolbox can keep things cold and even maintain frozen items. Of course, dependent upon ambient temps.

Fridge is probably one of the biggest drains on batteries, so batteries should be fully charged (or plug in).

6. Emergency. The coolbox can be used as a Igloo by tossing in bags of ice. If clean ice in containers (like frozen water bottles), can use for drinking.

For hot climates, bags of ice can also help coolbox from working too hard.

A. Repair Manual Self Test of Fridge

Search Repair Manual for " Carry Out Self-Test for Refrigerator"

1. Press arrow down button on central computer console 10 times.
2. In 60 seconds, a self-test occurs.
3. Look for the display to state a figure of 4.5 to 5.0 A (amps) which means fridge is okay.

B. Repair Manual Self-Test of Buttons

There is also a self-test to make sure the central computer console BUTTONS are working, including a specific test to make sure snowflake button is working. Over time, the buttons may not make contact internally and there is a fix per OneManVan thread.

C. Repair Manual

Repair Manual in pdf format can be found at bottom of this page:

Pin Connections. Do you know if any work has been done on fridge or cabinets recently? There is a wiring harness which runs from below fridge and into area beneath closet. There is a connector socket with a bunch of pins. If the pins are not perfectly aligned (could be accidentally bent), then fridge won't work. Happened to me--tech disconnected socket then reconnected but bent the pins. Fixed by disconnecting and straightening pins and reconnecting.

Other.

Fuse. If you find that the noise is not from fridge motor working away, check 15 Amp fuse (number 6).

Metal Plate. The metal plate inside the coolbox is what makes fridge cold. Do you see any frost or is the metal plate cold?

Vacuum. You may want to take the thin panel beneath fridge off (behind cabinet door). Then vacuum and clean the area. Presumably, the compressor (motor) and the condenser (coils) are located in that area.

Those are the easy things to check. For real diagnosis/repair, will have to wait for techies to chime in. So far, haven't heard of anyone needing fridge fixed. So you may be the pioneer.

Also, can check and ask for assistance from the James Cook Friends forum. Their fridge should be the same as ours as running off 12V.

The fridge compressor motor is likely a highly thought-of Danfoss compressor. If so, should be able to get a replacement if that's the issue.

As far as what refrigerant is in the cooling lines and leak/recharge, need a techie.

Looking forward to your investigation. At least have fun at the state park. As long as the main transportation stuff works, you can sorta cope with the getting-to-know-you quirks of the Westy.

OMG, the power wasn't on.



I'm so sorry to have wasted your time, OldWesty. Thank you for taking the time and starting with the most obvious first. We were ready to tear the thing out, turn it up side down and start shaking it.

Hope this helps other noobs out there.
