My ac fuse kept on blowing when I would turn on the ac, when I would unplug the pressure switch the fuse wouldn’t blow anymore. And also when I would unplug the clutch the fuse wouldn’t blow anymore. I accidentally placed a 25A fuse in the HVAC 10A fuse and the clutch started working again. But when I realized I turned off the AC and switched off the 25A fuse for a 10Amp fuse. But now the clutch works and the 10Amp ac fuse is not blowing anymore. Is there something I should be worried about?

Yes, so what is happening is the clutch coil is going bad on the compressor which is common, the fact that a larger amp fuse fixed it for a bit I would think the problem will return, but you never know :) I would run it until the problem returns and then you now have a better idea of what is wrong. If it does happen again unplug the compressor to see if the problem goes away to help confirm the issue. Ken
