You can check it with a meter, it's located in the compressor, can't recall the details at the moment but it can be checked from the connector. Have a look at RAVE, that will give you details or do a search, it's been covered many times.
You're new thermo switch may have failed. Or the solder joint to it. Did you secure it properly? If you have no leaks the compressor should never run long enough to get over hot. Have you checked the diaphragm valve for a leak? If that is sound and you have no leaks then either the new switch has failed or you have some other fault on the compressor. What was the condition of the brushes, armature and back bearing? Sometimes if you are not careful on re-assembly you can trap and hang the brush connection wire on the backplate and they will held off the armature. This way the motor will run for a while then when the brushes lose contact refuse to run. If you can start it by giving it a tap that maybe the problem.
Does manually running from the compressor bypass the thermo-switch cutoff??
If it does, then I would think the problem is the Thermo-switch not allowing the compressor to run in normal mode...
It is possible to bridge the thermo-switch to earth and see if the compressor still runs....but I wouldn't advise leaving it like this on a permenat basis for the obvious reasons!!

Have you checked the new switch for continuity from Orange to black? No continuity duff switch. Continuity bad connection in plugs. Or bad earth connection down side of EAS box on inner wing.
Yes Ant it just pulls relay in. Think there is a caution in EASunlock instructions not to force compressor for extended periods to avoid overheat. Happy Yule mate, don't do religious stuff.
