Have you checked the power to the outdoor unit? Make sure that 220v is actually going into the unit?

Customer: replied 12 months ago.
power is on. Yes 220. House is only six years old and unit is only six years old

Ok there is a fuse box/disconnect on the side of the house..this feeds power to the unit.

I need to know if we have 220v at the contactor inside the unit. If you press the contactor in does the unit kick on?
