i have an outdoor AC unit that won't start at all. I've check the thermostat and it will spool up the furnace blower, but nothing from the unit outside. Seems like the likely culprit may be the capacitor or the contactors. Going to check in the morning that the start indication voltage is coming through and then go on to looking at the capacitor and contactor. Am I missing anything? I will be pulling all breakers and being safe.
