My very old Waeco CF 60 fridge was running constantly and not cycling on and off.
( not stopping once the desired temp was reached)
End result was everything in fridge freezing and or premature flat battery while running on 12v, not good in either case.

So I got to work to replace the thermistor sensor.
First you need to turn it upside down and remove all screws holding base and compressor.

Next was to prise off the plastic base.
Not a easy job to do , but it's is do able..
All I did was start at the compressor end and use a screwdriver to prise it off.
I also used a metal ruler see pictures..

Once the plastic base is removed you can start cutting the insulation foam to locate the thermistor sensor..

In my case and the thermistor wasn't located on the bottom it ran up along the side of the fridge embedded in the insolation foam.
So I'm "not" gonna dig that out I'm just gonna replace it and fix it to the bottom of the fridge..

Like this.
See picture below, off the web..

Stay tuned once I fit the new thermistor sensor wire tomorrow and we'll see if it works..

Worst case scenario is I'm up for a new evakool fridge..馃槈
But I suppose that's not really that bad..馃榿

Slightly OT, I bought a factory seconds fridge for the caravan, saved heaps and delivery was fast.
This is the site for the fridge/freezers.

While you are at it fit 2 thermistors when 1 fails you have a spare which you only have to plug in this is what I did to my 60lt Weaco
That's a very good idea.
I'm lead to believe some fridge manufacturers now put 2 thirmistors in just incase one stuff's up ..
All they need to do it then is to simply plug the other in and BINGO!!! ... But they'll still charge you for a new one because most people are unaware they do this...

I'm not putting 2 in... The way I see it with this heap of chit is , if the the thirmistor works that's ok, if the thirmistor doesn't work, happy days with a new evakool..馃憤..


The job is finished and I just Turned the Waeco on..
I'll do a write up later tonight and I'll show you what I did..
And tell you if I was successful or not.

Well a bit of an update..

I'm not holding on to much faith of this working now..
It's been some hours since I turned the fridge on and the compressor hasn't stopped once on its first cycle yet...

But this is what I did...

I bought a new thirmistor wire which came with the thermal past stuff..
I couldn't buy the white plastic thermistor sensor holder as no one sells them.
Even the fridge repair joint I got the thirmistor wire sensor off can't locate any..
So I made my own ( see picture)
I vacuumed and cleaned it then
put the thermal paste chit on and hot clued the sensor casing down...
Then I filled the insolation where I cut with expansion foam.. Then I reinstalled the compressor and the bottom half of the plastic casing...

The whole thing went back together with no damage to the plastic casing at all..

I'll check on it later tonight to see if the compressor has stopped "if" it reaches my desired temperature...

Oh btw, I put frozen stuff in to help it get down to temp quicker too..

Well it seems if I turn the fridge temperature up the compressor stops...

Might be hope yet still...

Well before I went to bed last night I turned the temperature up on the old girl and it shut off the fridge compressor, when I woke up this morning the compressor was running. So it is working,馃憤 but I'm unsure if the compressor is shutting off Automatically..馃
I Can't sit by it 24/7 watching it to see what it's doing...
I'll further monitor it when I get home from work this arvo...
Stay tuned..馃槀

Put a thermometer inside it so every time you open it you can see how consistent the temp is.
Yes great minds think alike..馃槈..
I just bought one of those supercentre wireless thermometers...
Be a couple of days before delivery though..

Well the end result the thermistor didn't work where I located it ..
The compressor just runs and doesn't shut off.. Stuff us still freezing up...

Next step is to locate the thermistor somewhere on the condenser .

If that doesn't work..
Hello new evakool...

Why am I mucking around with this heap of chit..馃檮
I have to ask myself..

Alrighy, the bottom plastic casing is off and only took two minutes, the new thermistor is out also..
One thing I did notice was the amount of condensation on white plastic bit on the bottom already..

Anyway what I was thinking of doing was to run the thermistor wire up and bring it out where the light is situated inside the fridge, then run it to the metal condenser and temporarily tape it there to see what happens..

If that works I will then fix it to the condenser but on the outside of it...

Keep cool and stay tuned ...
Pardon the pun..馃榿

This could be your problem. Thermostats should up high in the hot zone of the fridge / cold room / freezer etc etc.

Just hang the thermostat near the light, not on the evaporator.
