Alan, the Sealey compressor is blowing the fuse because it is pulling too much power than the supply circuit can deliver.

One of those reasons is a too cold compressor, with thick, sluggish oil in the sump, adding load and the power necessary to start the compressor.

Yet, you say yours starts, and it runs for 5-10 seconds. That suggests to me that it could be the run capacitor that is at fault, assuming there has been no change in the electrical supply to the compressor, and that the operating ambient temperature is well above freezing.

Info about checking a capacitor can be found linked from the site map page.

Cheers,

Bill
