Have you check the outside breaker? If its ok then you got a problem in your electrical system inside the unit probably the contactor is not engaging this is where the 24 volts from the thermostat calls for the 240 volts to run the condenser fan and compressor. Be careful checking this out because of the high voltage.

The compressor is going out. The only time the compressor actually runs is when the clutch is engaged, the rest of the time the pulley acts as an idler pulley and just free wheels. I would suggest replacing the compressor and the accumulator.

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)

A/c outside unit is not working- fan will not work.


I assuming that the black box is a 100 amp breaker, which is connected to your condsensing unit (outside unit). If you open the box and pull the fuse then this will turn off/kill the power to your unit. As far as the buzzing noise it could be that the contactor is engaged. Hopefully, your fan motor is burnt out or the capicator is bad. If you take the access cover off and check for voltage at the contactor you should know if it is the fan motor. The voltage will come in at the bottom T1 T2 T3, once the contactor is engaged L1 L2 L3 will have the same power. Of course if your contactor is not engaging then thats the probelm, you can manual engage the contactor by pushing it in. There will be four wires two running to the capicator and the other to the contactor, these are the wires that control the fan motor. The other three wires run to your compressor. Hope this Helps Tim

My 2002 Expedition air conditioner will sometimes blow hot air and others cold air


I would check the following possibilities:
1. Is compressor clutch working? - You need to do this when the ac is blowing hot air only - locate compressor drive pulley on engine - rubber belt wraps around it. Start engine and set to max ac. When the ac is blowing hot air, look at the center of the compressor drive pulley using a good flash light - watch it for a while, it should be spinning with the pulley - this means the compressor is engaged. If not, the compressor is not engaged. If your ac is blowing hot air, then the compressor should be engaged and running (trying to cool). If it is not engaged, then your compressor clutch is probably going out. Could be low voltage to clutch, but more likely the clutch is worn out and only working some of the time. Note: if working normally, the compressor clutch will engage and disengage in cycles- but the air should always be cold. If clutch is bad, compressor would need to be replaced (sold as one unit). This is tricky to diagnose and could take some time - you need to do it when ac is blowing hot air but set to max cooling.

2. Low on refrigerant or refrigerant has moisture in it? If your ac blows cold initially after being off for a while, then heats up, and continues to regularly cycle back and forth between hot and cool air, then the system may be low on refrigerant or the refrigerant may have moisture in it that is freezing and restricting refrigerant flow. An a/c shop can check refrigerant level and even replace refrigerant if moisture is suspected.

Could be other issues, but I would start with these.

Good luck

Why does my fan runs continus. and the condenser won't run out side.


The fan runs continously because your condensor is not kicking on and removing the heat. The thermostat needs to come under the set temp. to kick off the fan. If your compressor doesn't run and the fan on the outside unit does run, your compressor has an issue. If nothing runs outside, then your transformer on the inside unit(air handler) has an issue. This could also be a control relay on the condenser or the air handler.

Blows air not cold I don't know how to tell if the compressor is dead or the thermostat


Hook a set of ac guages to the high and low side of your system and see what your pressures are. ballpark low should be 55 psi and ballpark high should be 350 psi. If off replace inline filter on high side, vacuum system and recharge with specified capacity and check pressures again. check to make sure clutch on compressor engages when you turn your ac on. if no charge in system clutch will not engage

Relay not engaging


This solution is based on a non-heat pump split system (furnace inside and condensing unit outside). The relay takes 24vac to energize and pull in closing the high voltage circuit to the compressor and condenser fan. If 24vac is present at the coil (two side terminals with smaller wire) and the relay does not pull in you need a new one. If no 24v is present then the outside unit is not getting the signal from the furnace and thermostat. If you pop off the furnace covers and access the control board your wires that go outside land on terminals C and Y. Y should have two wires, one from the thermostat and and the second goes to the outside unit. Test for 24v between C and Y. You must bypass the safety switch on the door prior to testing because that switch will cut off the power to the furnace. If nothing then you have a thermostat problem. If voltage is present you have a wiring issue between the furnace and outside unit.

I have a goodman furnace and ac unit the fan and heat work but every time i turn the ac on it blows the low voltage fuse ive replaced all low voltage wires to outside unit and thermostat i also replaced...


Look at the contactor on the condensing unit, remove the low voltage wires to the contactor and turn on the system. If the low voltage fuse doesn't blow, replace the contactor.

Fan will come on for heat(auto), but not for AC or set to ON


You have a blower relay in the furnace that's probably bad. In the heat mode the blower is on a temperature relay, in cooling mode the blower has to come on immediately so there is another relay for cooling. The green wire on the thermostat feeds that relay, so if you go to the furnace and shut the power off and find the green wire from the thermostat that feeds that relay and replace it, being careful to mark all the wires before removing them, also the relay terminals have numbers for identification.
