We've got an air con unit in the conservatory which blows the fuse as soon as it is powered on ...

It's a KFR-51GW which is a rebranded Toshiba 1800BTU split system.

I've had a look on the net, but I can't see a troubleshooting manual for it.

Before I call the engineer (who I imagine at this time of year are pretty busy!)

Any pointers?

Have you rewired / replaced the plug? (yet)

It would suggest the unit has been wired up incorrectly - probably on the interconnecting wire between the outdoor and indoor unit.

The only item in the system that could blow a fuse on its own is the compressor (ie if it has siezed), otherwise it sounds like a mistake.

Check ALL wiring.

OK, it's hardwired in and it's been running for 2 1/2 years no problem, although we hardly use it.

I guess I'll have to make the call and get a man in!

Ah, not good.

Can't see how it can be anything else except a siezed compressor or faulty capacitor.

Take the top off the outdoor unit and see if there is any apparent fault with the capacitor ie burnt wiring, distortion. (Capacitor looks like a small tin can).

My guess would be compressor, if so the most likely cause would be faulty installation.
