[Shop-talk] Window AC fan intermittent

[Jim Franklin]

A friend got a nice mini split system and have me his Frigidaire window AC. Weird problem is, the compressor runs when needed, but the fan shuts off intermittently. Sometimes it'll blow for a few minutes, other times for a few seconds. How long it stops is intermittent too. The compressor will even happily run while the fan doesn't. 

Is this a normal broken situation that's easily diagnosed or am I in for a world of troubleshooting?

thanks,
