Hi all,

We have a Sprite Tourer SW 2016 model with a Waeco Vaki vertical fridge ( 80L I believe) where the fridge motor appears jammed

How do you "un - jam" the motor if this is possible.

I have tried removing the fridge which is effectively simple enough HOWEVER facing the fridge on the right hand side of the fridge is a terminal block (electrics) which is preventing the removal because of the vertical wooden side wall which is secured from the inside of the fridge cabinet

It appears to me......that the fridge was built in where this now presents a challenge. I really do not want to cut on the wood work and it is impossible to access the securing screws of the side walls,etc.....

What am I missing folks...

Thanks in advance

Bruce

Hi Bruce

Try to type in this link to get assist on your fridge.

There is a number of discussions on the 4x4 community forum, also type in your name of fridge and model number following "problems" on Google

I do not know the type of fridge you have.  Thus do not under stand the full problem.  Maybe if you post a pic or 2 we can assist with some ideas.

I have copied the name you posted to google and found the normal WAECO chest freezers.  Is this what you have?

Got a better look at the fridge.  I doubt that the fridge will be built in through the side of the fridge.  They are normally screwed/ bolted in through the under side of the floor or panel it stands on.

Its like you said there are electronics on the sides and along the door ridges.

See if you can reach from below.

Thanks Leon

Fridge is bolted on the sides only. Bolts removed and fridge moved BUT the terminal block remains behind the vertical wooden frame where all wiring is individually secured. It is not the plug in/plug out type. It appears that I may have to access through the side cupboard by cutting. I am waiting on 2 caravan dealers/ repair companies to respond before i create any holes ....

So before we remove the fridge can we at least understand what we are looking at.

1. Is this a compressor fridge? That you refer to the "motor".  The "motor" would be a compressor.

If you can hear the compressor humming like it wants to start it is probably the run capacitor that has failed.  The run capacitor is permanently in circuit, it creates a slight phase shift which allows the motor to start.

2.  If indeed this is a compressor fridge then there is often a bi-metallic thermal electrical overload that is attached to the compressor housing.

It will be round, circa 12/15mm in diameter and a little higher. There will be one lead in and one out.

Some of these can be reset and have a button to do so. Check yours.

If you have one and there is no reset button then to check if its working. Unplug from the mains power supply. Remove both leads from the overload and check that there is continuity with a multi-meter.

If you have no multi-meter then connect the two leads together and insulate with tape.

Switch the fridge on. If the compressor starts then switch the fridge off immediately.

The overload has failed and may well have failed for a very good reason. If you try to run the fridge without an overload you could blow the compressor.

Replace the overload and see if the fridge operates.

If the overload has continuity then there is a chance the compressor has failed.

Hi Andrew and many thanks for very sound advice where at risk of my  protracted response ....if only I can access the fridge "compressor" which is positioned on top but to the one side of the fridge. The clearance around the fridge is about 10mm because of the surrounding cupboards. There is a conduit "box" of about 100mm x 50mm with all sorts of wiring, also attached to the side which prevents pulling out the fridge.

The fridge is 12Vdc sourced from the 106 A/hr battery fed from the 240V AC charger. So what I did was turn the fridge off and switched on at the control to level 1 where the motor, now a compressor started and hummed away merrily. I placed 2 bottles of water of same size, one in the freezer and one high in the fridge where after 2 hours i checked. All seemed okay where i turned the level up to 2 on the dial and dissappeared again for 2 hours. On inspection i felt the bottles where the freezer to touch was a little colder than the fridge bottle....regret I do not have a thermometer.

It then dawned that the compressor appeared to run the full periods without stopping. Is this normal/typical...ambient was my guess about 26 outside and inside the van much the same because I left the caravan door open. I then set the dial to 3 and checked after about an hour where everything again was still running well, except I got a bit excited and turned the dial to about 5 of 8 and the compressor stopped immediately and the LED started flashing 3 times repeatedly. What may be important is that I noticed that the fan at the back of the fridge did not " kick in" at any time which i felt strange. Whilst the fridge was operating during one of its cycles i managed to get access to the wiring on the fan ( through the 300mm x 180mm) air vent and tested voltage supply via a simple 12Vdc continuity light

Yes there was voltage but the motor she was not running....deceased I guess..?...can only replace when business's open again

Thinking..?.. PERHAPS the motor switches off beause the fan does not operate...... but does the compressor sense the unavailability of the fan from start up, irrespective of what position the dial is at on start up - i do not know......any response is gratefully accepted

Regards

So generally speaking 1 is coldest while 8 would be warmest. So it is no surprise that the compressor would have stopped.

Not sure what the led indicates?

Can you get a pic of the fan arrangement? It the fan cooling the fins or the compressor?

So the fridge is 12V ONLY?

Is the fan a modification or part of the original fridge?

Hi Andrew 

Sorry for delay where I confirm

** that the fridge is 12 V only

** the fan is an integral part of the fridge 

** 0 on the dial adjustment is off, 1 on is warmest through to 8 the coldest

I have (hopefully) attached some pics

Thanks so much , again

Bruce

"0 on the dial adjustment is off, 1 on is warmest through to 8 the coldest"

And you are 100% sure of this? Sorry to second guess you.
