Oh dear Scandinova fridge freezer fridge section packed up yesterday. On
inspection stat appeared ok but danfoss compressor totally dead (U102 TL
2.5A is this the model number of the compressor). Checked compressor
windings they appear ok but unsure what the resistance should be. Also
anyone know how the PTC? start relay operates. I think it is this that is
faulty but not sure how do I check?. Hopefully it is not the compressor.
In the region of 4 ohms on start and 30 ohms on run.
It's probably the relay. It's a slab of ceramic material which feeds
the start winding. It has a low resistance when cold, supplying a big
current, but quickly heats up and goes high resistance, effectively
disconnecting the start winding. The device usually shows signs of
overheating i.e. discoloured.
