I tried to turn on my AC for the first time this season and about a half hour later I realized it was not any cooler in the house. Thermostat is set to cool, 6 degrees cooler than the room temp, the fan is blowing but the air is not cool. I checked on the condenser and nothing is on, no fan no pump... nothing. I checked the switch to make sure it is set to on and IO checked the breaker to make sure is was not tripped. Why won't the condenser come on? Can anybody help?
