Where did the wires of the fridge go?

In an ambitious mood, I ordered the brewspark, couple of sensors and some SSR’s.
Went to MediaMarkt, for the Dutch among us, bought the cheapest fridge (OK OFR34026A1) they had and shelved the whole thing for about a year. Per my usual MO…

Cut to today, and lo and behold, when using the fridge hacking guide, it seems my compressor is missing a couple of wires…
Now, according to the wiring diagram on the fridge, the starter relay, the capacitor, and the wiring for the light is all there. I suspect the manufacturer tucked it all neatly away into the side of the fridge.

The thing I am most anxious about, is the live feed to the compressor from the thermostat, and the L feed from the power cord.
From what I can tell, there is just one (1) pair of wires going to the compressor. The blue/neutral from the power cord, and (what I suspect) the feed from the thermostat.

The top connection is coming from the thermostat, the bottom one is neutral.

The current relay they are connected to, looks similar to this one.

My main question is:
Am I correct in assuming that the grey line, is the one I need to attach to the SSR to control the compressor?
That would be the “C” in the guide diagram.

Any and all help is appreciated.

You should connect the SSR between L and C, replacing the thermostat in the schematic.

I think the grey wire is probably the wire coming back from the thermostat.
I can’t really see it in the photo, but my guess is your compressor has 3 wires:

  • Protective Earth (PE), aarde in Dutch, yellow-green.
  • Neutal, blue, connected directly to power cord.
  • Grey, live after being switched by the thermostat.

So brown -> thermostat -> grey at compressor.
You now want brown -> SSR -> grey at compressor.

Hi Elco,
Thing is… What is “C” when looking at the pictures?
I have detached the wires from the compressor, as shown below at the following url:
wires decoupled from compressor

The complete detached wiring looks like:

In the previous photo, I suspect, the grey connector on the right, perpendicular and behind the blue connector is “C”.

Hmm, I missed a good deal of your reply before writing mine…

You are correct in your guess.
And I was under the same impression, and I must admit: that’s pretty reassuring!

I edited my answer for clarity. Sounds like you figured it out.
