First check the main panel breaker. Then check the breaker/disconnect at the condenser. If power to unit check contactor inside panel, make sure its pulled in.

Sounds like the contactor in the condensing unit is stuck. That is why it will not turn off when the thermostat is satisfied. If the inside air handler is not blowing and the outside condensing unit is running, then this will cause the inside coils to freeze up rather quickly.
The contactor is located in the outside condensing uni in the electrical compartment.
If it is sticking it will need to be replaced.

Outside unit won't come on. Drain pas appears dry/.


if nothing comes on (on the outside unit) when you turn on AC (and the inside unit runs ok) I would check the fuses and/or the breaker for the outside unit. I would suspect a fuse blown or a breaker tripped. It's also possible that your 'low voltage' (24V) thermostat wire has been cut (by lawn mower) or chewed into (by dog). If the problem is the low voltage wire you can easily splice it back together - just be sure all power is off.

The central air turns on, but does not cool. The fan outside of the house is not moving. Is there a switch I need to use to turn the outside fan on?


There should be an electrical box next to your exterior unit. Open it up and there should be a pull handle on an electrical bridge. Usually when it is turned one way it will make an electrical connection and if it is rotated 180 degrees and plugged in it won't make an electrical connection.

Can i run the fan on my inside unit if the outside unit is not working


You should be able to run the fan on the inside unit if the outside one isn't working. If you're worried, turn off the circuit breaker for the outside unit. If you don't know why the outside unit isn't working, check the circuit breaker at the breaker panel, check the breaker inside the box that electrically connects to the outside unit, and check the outside unit for a reset button.

I need wiring manual for goodman mini split.


outside unit L1 and L2 are load (input 240vac)
then you have control voltage, usually yellow and blue (24vac) this connects to some 18/2 thermostat wire which goes inside as white and red.

note: this unit may only need 24v control which is 2 wires from the inside unit and also 3 wires 2 hot 1 ground for line voltage.

STANDARD WIRING
on the inside unit you have green, white, blue and red control wires.

on your thermostat you have white, red, yellow and green

you run the wire from the outside unit to the inside unit. then run a 18/4 wire to the thermostat if wired and join the following wires.

inside unit thermostat outside unit
green------------------------green
white-------------------------white
red----------------------------red
blue-------------------------------------------------------blue
yellow--------------------yellow

Outside unit not working


If the heating and cooling is working O.K. and maintaining the proper temperatures it is possible that your outside unit is in its off cycle. If the inside unit is running and the outside unit is not with an elevated temperature inside check the power supply to the outside unit. Most units have a disconnect located near them. Check the disconnect and make sure it is set to the on position. Listen for a hum noise at the outside unit which could indicate that the control power is being supplied to the contactor.

Non-working outside unit


If your unit is blowing heat inside and it's not a heat pump. It will be most likely electric heat in your case.
Sounds like you have a split unit meaning the condenser is outside and the cooling and the heat features are inside or under your home.If your Rudd is a heat-pump the outside unit will cycle/blow cold air outside in winter and hot air will cycle/blow outside during the summer season. Now, if for some reason the heat  is not coming on inside the house, would be the only reason that you would need to be concerned. Being a heat relay or breaker of could cause that problem. Hope this helps you, Sea Breeze
