Bump the fuse up 5 amps. Is it the 15 amp condenser fan fuse you keep blowing?driverdriver Thanks this.

The condenser fuse on the new ones is a 20. The first time it blew I just happened be to going to get it serviced the next day.
The replaced the fan cause at that time TK thought the fans were faulty.
It blew a few more time after that.
The next time I took it in for service the tech said that their (TK) line of thought was that the fuse just needs to be a 25.
Apparently there is a mild power surge when the fan kicks in that's just enough to eventually blow the fuse.
Since I put the 25 in I've never had it blow again. -
Bump it up 5amps? I fixed mine earlier today, different issues. Let it run 4 hours before I left the house. Get parked and now it's throwing acs code. All the fans are working. Not sure why it's throwing the code but I'll try bumping up 5 amps.

I just attempted this. Been running approximately 4 minutes now with the 25 amp. I couldn't find any bare wire to either condenser fan that could be shorting out. They both turn on. It ran for 4 hours before I left after fixing some other stuff. Don't know why the 20 amp was blowing so much. But I just heard the compressor cycle. It kicked out and back in. So I guess all is well now. Don't see any flames or smell anything burning.
