It must blow, otherwise the coil will frost up in winter.

Check the neutral connections right through to the main supply..

2 things that will blow any ac system inverter is
1/ compressor windings down to ground. No good just testing with multi meter you have to do mega test to prove.
2/ Power supply problem. Floating or disconnected Neutral will cause major damage to the inverter.

Never try to run any ac inverter system untill absolutly sure power supply & motor windings are ok.
