Compressor heats up and after 30s clixon turn it off (see the video)

from 25s to 60s the compressor on the right goes on and off. Left compressor works well.
Clixon protect it from overheating. In the 30s of works, touching the pipes i can fell the gas is correctly compressed (it's hot) and at the end is correctly cold.
Compressors are 19 years old.

Right compressor is died and must be changed? (maybe the coils? should i check them with a tester?)
New combined fridge-freezer...any suggestion? how are the Bekos?

Most likely compressor faulty. An amp meter would confirm if it is pulling over its rated run current.

Sounds like new fridge time...

to change the first intervention clixon

I don't understand, what do you mean? (che hai detto?)

[pivic]

Windings resistance test failed: starting 12 ohms and running 17,5 ohms (they sould be 24,4 and 22). Same measure on the good compressor is ok: 24,8 and 23,5.
It is worth the money to change the compressor or it's best to buy a new combined fridge-freezer?

I'd probably fit a new compressor if it was mine (but i would do it myself so would be cheap to do) and i liked the fridge, but it may be wiser to just replace it with new as it will likely be more energy efficient, just don't expect the replacement to last as long.
If you do decide to buy new i would look for one with the least amount of electronics on it as there will be less to go wrong.

... more energy efficient............ with the least amount of electronics on it as there will be less to go wrong.
A+ are around 400€...there's a Bosh A+++ (Inverter Linear Compressor) at 650€...maybe it's worth the investment and 200€ could be saved from minor energy consumption over the next few years?

What's wrong with electronics? I'm an electronic engineer :D, electronics today is everywere, i don't think it's so bad to have in a fridge.

If the thing is 20 years old and the cost difference is
only 200€ I would buy the new fridge freezer.

i wanted to use the fridge again and i let it too cool down for 2 hours...the compressor died :confused:. Now i have two broken compressor...there's any useful thing to do with them?

Build a concrete plinth in the garden and display them/it as modern art?

:cool:

i'm googling "r12 gas dangers" :o

[pivic]

Fridge compressor still working :D...windings resistances ok, it was only overheated and klixon started.
