Does the current for the compressor not go via the relay though? So if it's getting warm, suggests it's the pump motor, rather than the relay at fault. Sorry if I'm misunderstanding how it works. This thread sounds like the same thing
I got the relay off, it's this one. Is there any way to tell if it is the cause before ordering the replacement?

You can measure the resistance of the motor coils to discount theose being burnt out. It takes a few seconds for a multimeter to stabilise at a reading
The 3 pins Common, Start and Run.
S-R (6K ohm? ) highest reading through both coils.
C-S (4K) resistance of Starting windings
C-R (2K) resistance of Run windings
Any pin to Earth should be open.Does the capacitor (silver cylinder to the left of your motor) seem to be bulged or leaking?
Do you have a multimeter to test capacitance?You can test the coil of the relay for continuity and across the switched terminals but it can be difficult to tell if it's actually switching when in situe.
Does it smell burnt or have a discoloured area?Edit.
Some current will flow through the run winding, even if the motor is stationary. Hence getting warm.
I couldn't hear it, but does yours actually run for a few seconds and then trip off, or just sit there humming before tripping.

The compressor (Black football) would get warm as its being fed electricity for when it's normally running. But it needs the relay to switch contacts over to start the motor first. Otherwise the motor is stationary, drawing current and overheating.
It's still possible that the compressor pump has seized, so the motor can't turn, but way rarer than the PTC/starter giving up.
From your vud, this may have been the Pt number on your comp. Take off the white bit, and get a Pt number for that.
