Hello, I need the brand name, model number and age of the unit outside that is not running... and I need to know how hot it has been lately.
Tell me a lot about your technical skill sets and if you have a multi meter or not so that I can coach you most effectively.
We can go from there.
Thanks you will need to buy a $30 type, self ranging multi meter to check voltage to the outside unit that is not running and a few other things after that.
all hardware stores carry them.
Practice with it for a while, we can go from there
the power is off to the outside unit, or it is not getting its 24volt signal to pull in the contactor that runs the fan and compressor, or the contactor is bad, or the high pressure safety cut is tripped. that in the diagram follow the wires to and press its reset button.
Then clean the condenser coil
thats a summary, i will step you though it once you have a meter
if its a box about 24 inches tall, 36 inches wide and 50 inches long its a packaged unit and will be connected to the house by air ducts,, there will be no inside unit
Thanks, ***** ***** the attic then if its not there and your house is not on a slab look under the house, or in the garage.
If there is a gas line running to them and a vent through the roof they are gas furnaces with a blower, and the cooling coil fits on the outlet end of the furnace.
If its not a gas furnace it will be an electric furnace and you will see a large disconnect switch mounted nearby.
remove the door from the blower compartment and take a well lit, close up photo of the wiring diagram from straight on and very very well focused... attach it here using the paper clip icon at the right end of your tool bar
we can go from there
thanks. send me that wiring diagram then, and a photo of there thermostat wire connections to the printed circuit card in the blower compartment and I will mark them up with trouble shooting instructions.
Hello again, if the capacitor is bad for the compressor side, the compressor will attempt to start from time to time and it will be very warm on top.
while it would not hurt to replace the capacitor at this stage, there is probably something else wrong, I suspect a burnt wire connection at the compressor, look for that
Hello again, did you locate the actual spot where the 3 wires attach at the compressor, or just the 3 wires themselves.
the next trace each of the 3 wires back to their source, two will to the T1 and T2 terminals on the contactor and one wire will go the run capacitor.
Measure the voltage across the two at the contactor, and between each of those and the one that attaches to the capacitor.
tell me what the reads are, we can go from there.
Hello again, there are no time limits or fixed schedules with me, just post and I will pick it up as soon as I can,
basically I want to see if the power, 230v is getting to the compressor or not, you can check that where the wires connect to the contactor that is inside where the all the controls and the run capacitor is.
