Smeg Fab32 f32strp3 not cooling

[Dfounde]

Hi
i have a Smeg fridge. Freezer part works fine, the fridge won’t cool though.
ive checked the internal thermostat with ohm meter and it gets a reading.
right hand side compressor is working and feel it doing something.
inside fridge I can here it pushing something through but it’s not cooling.

I have a spare thermostat from a different fridge(think it’s universal)

any advice?

has this got 2 compressors then ? one for fridge one for freezer ? it must be very old ?

Hi yes it has 2 compressors.
not sure how old it is. I acquired it. Model is s32strtp Fab32… doesn’t seem that old

any advice?

need to check if geting a live to the fridge compressor ..from the fridge state ,usually the black wire .. at bottom of start relay on compressor .. if you are . .if not will be the state ,, if you want to check compressor take relay of compressor and check with ohmeter across the 3 pins ,, should get a reading across the 3 .. if not compressor gone , that test is with power off ,, ie mains

if both compressors are warm to touch .. the fridge one could have lost its compression or lost its refrigerant .. which is not a easy fix these days

Ok, the there is a reading coming through on the relay.
i left it on all night last night and it is slightly cooler than it was. But not fridge cool!

like I say the compressor is running.

could it be the thermostat? Can I bypass the thermostat? Bridge black & blue feeds inside thermostat?

Update:

ive bypassed the thermostat and the fridge is making a normal fridge noise, but not cooling.

is this likely to be gas?

is the comp deffo running?
is the discharge pipe hot?
is the suction pipe cold?
is the top of the compressor too hot to touch?

Yes
warmish
ambient
no hotter than the rest of compressor

short of refrigerant i would say, if the discharge is warm and its coming back ambient sounds like it could be short.
