Recently, I installed a slim a/c condenser fan. Since then, the condenser fan fuse in the under-hood fuse box randomly blows. It doesn't blow immediately, it takes a couple days.
I have checked all of the wiring and it is good.

It's a 1550 CFM, 80 watt, 10" slim fan.

Do the slim fans draw too much power for the 20A fuse that is in the fuse box?



Basically what I am trying to figure out is:
Can I use a higher rated fuse?
If so, what's the highest I can go and still be safe?

 

I would think that the company who sold the fan can tell you what the recommended fuse rating is for it. Then go from there.

 

The condenser fan fuse also feeds the compressor clutch, which can normally use up to 5 amps. So there's only 15 amps left for the fan. If your fan uses more than 15 amps you should run dedicated new wiring and a new relay for it to handle the higher current. Drive the coil of your new relay from the stock leads for the old fan.

 

Alright guys, thanks for the help. I'm still waiting for a response from the seller about the amperage of the fan.
