Not showing voltage outside

The wiring to the unit shows power inside but not outside on the unit

    Central AC usually has a breaker (2 if it's a 220V unit) in the panel in your home as well as a disconnect at the outside unit. If the outside disconnect is an unfused type with a pullout, the pullout may be in the OFF position. Have you checked this already, or am I missing something else about the trouble you're having?

It is probably a broken t-stat wire outside. Use a meter and check for continuity through all the wires and replace the bad one at the condenser and the a/h

AlvinInside unit fan works; outside unit does not come on. Inside unit showed H5 code once. How do I proceed?


H is most likely for heat pump, meaning error 5 on outdoor unit. My guess would be low pressure since your power to the indoor unit most likely comes from the outdoor unit. Check manual for codes or research model number error codes.

Compressor want come on


Here is what to do . Pull out or turn off Electrical disconnect behind unit . Carefully remove panel covering controls in unit . Note most units have a flat panel with a few screws, but some GE units have a welded metal box on top of unit which needs to be removed. After exposing controls. replace or turn on disconnect. Then take a plastic handled screwdriver and push in on center of contactor (boxlike part with a lot of wires hooked ) If the compressor now comes on release contactor , and check for 24 Volts AC at base of contactor where thermostat (small wires that run on outside of black refrigerant line ) with thermostat on and calling for cool you should measure 24 to 28 volts . If voltage is present replace contactor after disconnecting from power. If no voltage go inside , remove cover from thermostat, and check for 24 volts between red ( R) and yellow (Y ) terminals on thermostat , If voltage is present , replace thermostat , no voltage check voltage in heater / air handler if you have voltage at air handler , replace thermostat wire from heater to thermostat / if no voltage check for blown fuse in heater , this should be either an inline fuse or an automotive type fuse plugged into circuit board (with power to heater disconnected check broken wire or black mark in fuse when held up to light. If fuse good turn on power to heater and check for 230v to one side of transformer, if you get voltage to Primary (incoming side ) of transformer, check output side of transformer for 24 - 28 volts. If transformer shows input but no output replace transformer after turning power off. If you heard a buzzing or grinding noise , when pushing in contactor , but compressor didn't start look at run capacitor (this is round or oval shaped object with wires going to contactor and compressor ) Looking at area where wires plug this should be a flat surface , if it looks domed shaped or bulging out , it is blown and needs replaced , use same mfd rating and 440 Volts to be on safe side. / If there was no noise from compressor when contactor was pushed in , put your hand on top of compressor (black object in center of unit ) If hot , allow to cool for at least three hours with power to unit turned off and retest . If compressor comes on after cooling , check for bad fan motor in outside unit (it may make a squealing or wining noise and stop runing for a while , also check for / clean outdoor coils
Hope this helps .
Thanks,
Alex

I have a WestPoint air conditioner, wsg series 12.2. The rooftop unit has a sticker that says 220v, but the inside unit (which is wired to the outside unit) is 110v. Is this 110 or 220? How do you


The inside unit is 110V. Now when you say wired to the outside unit you must be talking about the control wiring - not the high voltage wiring. Unless of course the outside unit is providing power to the inside unit.

You may need an electrician to wire it up for you -

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.

Outside unit is not turning on but the inside unit is


I would check the fuses or breaker to the outside unit.
If nothing (either the fan motor or the compressor) is running - chances are you have no power to the outside unit.
It's also possible that your low voltage wire from the inside t-stat has been 'cut' or 'chewed into' (by a dog), but my guess is the fuses/breaker.

I have a rheem criterion ii a/c and furnace. The power source from the a/c outside unit is not hooked up inside. Where on the unit indoors does the wire attach.


two wires go from the inside unit to the outside unit. Y terminal and C terminal (both low voltage). Power should come from circuit breaker panel (20 or 30 amp double breaker).

Have a mistral air con, outside unit not working


there is no fuse on your condensing unit outside. pull the disconnect to kill the power to the unit and take off the removable panel above the 2 service valves. there will be an oval shaped capacitor that is marked herm and fan. there will be a rupture disc on the top that may have ruptured. also inspect the low voltage wiring(will still be hot unless you turn off the switch at your furnace). this low voltage wire operates a magnetic coil on the bottom of the contactor that closes a high voltage circuit to the fan and compressor.

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

I want to find the transformer for the 36 volt inside unit. Is it in the inside unit or outside unit .I have no power to the inside unit however the outside unit has power,and the inside unit appears to be...


It's a 24v transformer. Your indoor unit houses the transformer for the outdoor unit. The outdoor has a low voltage (24v) supply running to it to push in the contactor for the outdoor unit to run. If your air handler inside has no power then it will kill your LOW VOLTAGE power to the outdoor unit. You will still have the high voltage power to the outdoor unit. You may have a fuse on the switch for your air handler blown if there is one. On the disconnect switch mounted to your air handler, you will have a door to open and a fuse in there. If not, check your main breaker at the panel. If you don't know what a transformer looks like, you may want to have someone familiar with electrical of HVAC help you. To check the transformer for power, you first need power to your air handler, which you don't have. I would say that is not your problem. I would assume your air conditioner is not running outside, correct? Your problem is the power (HIGH VOLTAGE) to your air handler. Loose wires, blown fuse, tripped breaker etc...
