Hello Crew,
I searched the forum, but could not find the Service Manual for my Bosch B22CS30SN Side-by-Side Refer.

My issue:
Unit not making cold on either side.

No error codes when pressing "+" and "-“.

All Fans running.

No 'ice' build up.

Compressor seems to run after initial start-up, but then stops.

The evaporator heater show 63 ohms.

The heater 'element' at base of, and below evaporator shows 370 ohms (reads 0.370 with MM set to '2K') resistance.

The evaporator thermal fuse shows 0 resistance. Is that the same as 'Good' continuity?

The evaporator thermistor reads 7.0K at room temp and 14.8K ohms resistance at 32'F.

Is it possible to 'jump' any of these components to make the fridg run (to check that the control boards are functioning)?

Any help or a link the the Service Manual would be greatly appreciated.
Thx!

Perhaps I'm dealing with a sealed system issue?
If I were to try to add freon, how many grams should be added to this 'frig?

I don't have any Bosch tech data information on this model, and without that we are dead in the water.

Is the compressor extremely hot to the touch when it shuts off?

The compressor was starting after a power-down 'reset', but now does not seem to run at all. Is this a symptom of a 'sealed system failure'?

 

[Jake]

Possibly yes, does the compressor even try to start?

Touch the top of the compressor, is it hot or cold?

The Compressor no longer starts.
When I first pulled the frig out to investigate, the compressor was running (and warm).
But now, it will not start and is not warm.... :[

 

[Jake]

Ok, since I don't have any tech data information on Bosch, Its best to get a Bosch Tech out to see what's going on.

Well, I've added 7oz of freon and the compressor STILL not starting. NO error codes after pressing "+/-". Troubleshooting tree says replace OLP/PTC. Is there a seller available to purchase and return if the OLP/PTC does not correct my issue?

 

[Jake]

No, those days are long gone my friend.

This seems to be the P/N for my frig, and looks like it is available and ONLY $400!
It is possible to test the Compressor Control Unit?

I don't know Randell, Like I mentioned, I have never worked on any Bosch products.

Hopefully a Bosch tech will tell you if you can or not.
