Power module replaced on my Thermador T241F70NSP/03

Customer Question

Power module replaced on my Thermador T241F70NSP/03 built-in-freezer which fixed inoperative display & fans but now I get a click sound & the compressor is not starting. How do you check compressor?
I have gone thru all the self tests & service tests but no error codes come up but the component test seemed to get to starting the compressor, hearing a click sound but no start & test kept repeating that step over & over until I terminated the test.
What to do next?

Measure the resistance between all of the pins on the compressor. They should be all the same, are they?

See attached diagram showing tested resistance between all of the pins on the compressor

That model shows it having a DC compressor with an inverter board. Can you post a picture of the compressor area?

So the compressor tests good electrically then. Is it just not getting power to it?

Customer: replied 3 months ago.
I don't know how do I check that out?

Test for power at the wire going to the overload that goes over the compressor pin that is by itself.

Need more info re that wire & the overload?

Do you see the part that plugs onto the single compressor pin? They are usually white with a small spade connector on one side and a small hole on the other that goes on the compressor pin.
