My Amana A/C unit keeps blowing fuses. The heat worked fine all winter. I have replaced the fuse 3 times, checked all the connections for corrosion... The manual says that it could be reverse polarity? How do I check this? THe unit outside is not blocked. It is only 3 years old. Filter looks good, 3months old, no obstructions in house??? Need help?

Which fuse blows the outdoor fuses or the furnace fuse?
where did you replace the fuses and what type of fuses?
