The ductless mini splits, can be a bit tricky,,, most of them,, you feed the outdoor unit with a 220 volt line, then 4 wires run from the outdoor unit to the indoor unit.
The outdoor unit is the one that supplies power to the indoor unit, usually, 4 wires, run from the outdoor unit to the indoor unit.
So you have 2 leads and a ground that feed the outdoor unit,,
G - ground,, and a L1 and a L2,, these are the terminals that you feed your 220 volt to the outdoor unit,, then 4 wires from the outdoor to the indoor unit,, usually 120 volt is fed over these wires to run the indoor unit blower and a digital signal is also run over these wires as well as the 120 volt current,, just make sure that the marked terminals are matched on the outdoor and indoor unit;
Example: If there is a S1 terminal outdoors, make sure that the same wire hooks up to the S1 terminal on the indoor..
Hopefully no damage has been done to the indoor unit.
This being said,, allot of brands use a variaty of wiring connections, what I discribed above is a more normal setup.
That wiring schamatic will be your guide.
I hope this helps,,
Have a great Day,
Paul Gibson

What was the voltage that you measured? Are the units 220 volt or 120 volt. Units that size are usually fed by 220 volts. What is the current rateing of the circuit breakers? Are they a double breaker with a handeling capacity of 20 amps or are they 15 amps.

You didn't mention if they ever worked? Are you feeding 120 volts or 220 volts to the two units?

Good luck,

My miller ac outside unit will not come on unit is only 2 years old. I checked breakers and capacitor I have voltage to outside unit? any recommendations?

If you were able to check the voltage, did you check to see if you had 24volts at the contactor? Did you
have 220 volts coming into the contactor? If no to the
first question and yes to the 2nd question, take a
insulated screwdriver and push the contactor in, the
unit will run. You have a low voltage problem.

2nd, do not reference the 220 volts to ground, if you
dont have 220volts feeding into the contactor,
example read voltage between L1 and L2.

Installed 4 brand new units, I have 233 volts going into the inside unit, nothing on the outside. Units will not even power on, no beeps, no fan, no nothing

Is there a disconnect next to the outside unit (required by code here in the lower 48). If so check to see if you have voltage to it, check the breaker going to the outside unit. Check on the inside unit circuit board for a blown fuse.

Unit not coming on. air isn't getting cold

First check the breakers for the condensing unit (outside unit) and the disconect outside by the unit (could be a breaker ,a pull off/on switch or fuses)If its ok , you should have 220 ,240 volts to the unit contactor (you'll see it after removing the cover on the condensing unit).When the termostat is in the cold position and the temperature its set is lower than the one inside the house the contactor should be pulled in and give power to the compresor and the fan.But if the termostat is in the cooldest set and the blower inside the house works and the contactor in the condensing unit is not pull in the problem is in the termostat or in the low voltage wire.

I have bard central unit model# a/c ph11361 blower not running

220 is just putting two 110 volt circuits together. You should read only 110 volts from each leg to ground. But you should read 220 between both legs. Measuring between two legs that are supposed to be 220 and you read nothing than you are not measuring the differences. This means you are only getting 110 volts. Check your units data plate and make sure you need 220. Usually the condenser fan on a split system is 110 volts and the condenser fan is 220 volts. Which motor are you checking?

Heat coils in central air conditioning unit look fine under examination, checked with an ohmmeter both coils showed continuity. Power at both coils indicated 110 volts. Unit fan runs fine but there is no...

Are you getting 120 vac or 220 vac at the unit? Check the voltage at the first terminals inside the unit as well as the breaker. You should have 220 vac at the elements and you are dropping a leg some where.

I cant get my air conditioner to go on.

Yes.. first check circuit breakers on the outside unit. then.. make sure the power disconnect beside the outside unit is put in correctly. Sometimes a technition will replace them upside down. if you have power to the unit and it still has not came on.. make sure the unit is getting a "Call signal" from the thermostat. if there is a call signal from the thermostate reaching the outside unit, then listen for a "CLICK" when the thermostat is turned up and down. The click is the sound of the "COntactor" making contact when the unit recieves the "CALL Signal" This means the UNIT is most likely getting 220 volts, Check the voltage input to be sure with a Volt meter. IF you are still getting power and the unit is not running.. the run capacitor is most likely bad.

The outside unit refuses to come on resulting in no cooling in the inside

You have an electrical problem. It is either a lack of 220 volts getting to the outside half of the a/c or the 24 volt circuit not activating the contactor (big relay) that carries 220 to the compressor.

Intertherm outside unit - s3ba-036k - does not run

Measure the voltage across the line. The outside unit normally runs on 220 Volts. Measuring each side of the line to ground will give 110 Volts. If your outside disconnect is of a fused type one fuse could be blown. If a fuse is blown on one side of the line you will read zero volts differential across the line.

Check the type of fuse used in the disconnect. Make sure the proper size time delay fuse is installed on both sides of the line at the disconnect.
