What is wrong when weather king air conditioning not coming on?
If you turn the unit to heat and say set the temp to 85 and the furnace fires up but the blower doesnt turn on after a minute or 3, 3 things to check. One is the fan control switch in the plenum. It says the plenum is hot and ok to turn on the blower. If the switch is ok, then check the blower and the capacitor. Set unit to AC and set temp to meat locker. Outside compressor and fan should come on immediately. If not
have a friend turn it on from inside while you listen outside. If you here a click, the contactor is good. If it is, check to see if the 230 Volts circuit breaker (inside in the panel) has not tripped. If thats good check the disconnect next to the outside unit. Then check for 240 AC or so on the far side of the contactor. If thats good, check the split capacitor with the power off. If all the above is good, and the fan doesnt come on, replace the motor in the outside fan. If the fan does come on and the compressor does not, see if there is a protection switch that needs to be reset. And if you dont understand the above, call a reputable dealer (ask your neighbors who they trust)
