Hi, If the main breaker is fine, the box at the unit is the disconnect box for it. If you pull the block out of the box, you will have a plastic cover there. Remove this cover and there are 2- fuses inside. If you have a meter you can ohm them out. If not, pick up 2 of the same amps. Probably 30 to 35 amps depending on the size of your unit. I am not sure about this one wire you say that is pulled out. If its not coming from the disconnect box there at the unit, or its not the small conductor thermostat wiring, you should try and find out what it is. If you have no dogs that may have chewed the stat wires, I wouldn't think this wire has any thing to do with the a/c. If the indoor unit is also off, remove the control panel. This is a new system so look for the circuit control board. It will have a 3 to 5 amp automotive type plug in fuse in it. Check to see if it has blown. You can normally tell by looking at the top metal strip, it will be burned, blackened. If your not sure, just replace it. You should have a Red led light on the board, or a hole to peep through to see if you can see if the led is on. If it is on, the fuse is good and we will need to go further.You may have a stat problem but first check these things. If the indoor unit is off to, start there looking for that small fuse. This is more then likely the fault. Keep me posted,
Sincerely,
Shastalaker7
PS When you remove the panel on the indoor unit, some will have a switch that kills the power when you do take it off. If so, you can tape it down to restore power. Make sure you remove the tape when done and put the panel on right or the unit will not start. I would start at the indoor unit control board.

Won't power on!


You may need an electrician or tech to look at this as you will probably need special tools. If you have a multimeter, check the interconnect cable - the cable that connects the indoor to the outdoor and allows it to communicate. Check that they are connected correctly and to the right terminals. Check the voltages - supply and signal. Set your meter to DC Volts, test between terminals 2 and 3, of the outdoor unit and wiring terminals. You
should see 0-65 V dc, it will be fluctuating.
If the Voltage is not present disconnect the inter unit wiring, test the Voltage on the wiring terminals again, If
No Voltage is present, the outdoor PCB must be faulty.

How to fix problem of Air conditioner doesn't turn on


If your central air conditioner doesn't go on automatically:
1) Be sure the thermostat is set to “cool” and that the set temperature is well below the ambient temperature.
2) A central air conditioner should be on a dedicated 240-volt circuit; check the main electrical panel and any secondary circuit panels for a tripped breaker or blown fuse. If you find the problem there, reset the breaker or replace the fuse.
3) Make sure the furnace power switch is turned on and that the outdoor condenser's power switch, which is mounted on the outdoor unit, hasn't been shut off. Also, be sure the 240-volt disconnect next to the compressor, which is in a metal box, usually mounted on the house wall, hasn't been shut off.
4) Turn off the power to the air conditioner and check the thermostat.
5) Remove the thermostat's cover and unscrew the wire from the Y terminal.
6) Turn the power back on.
7) Holding the wire by its insulation ONLY, touch the bare end to the R terminal and hold it there for about two minutes. If the compressor kicks on, the thermostat is faulty; replace it or call an air-conditioning technician. If the compressor doesn't go on when you hold the two wires together, turn the power back off and call a technician.

I have Rheem RAKA-060JAZ. When a/c is turned on, we feel the breeze, but no cool air. Later learned inside unit is works, but outdoor unit won't start. Outdoor unit makes no sound whatsoever.


You might consider checking the circuit breakers in your fuse panel, also the pull out fuse block mounted on the side of your house next to your a/c, you might as well check those fuses while you are at it. And lastly, look at the small thermostat wire that is attached to your cooling lines from the house to the unit. Sometimes people cut through those wires while trimming the weeds from that area. Hope this helps.

Tempstar Air Conditioner wont come on


Sounds like you need a new contactor in the condenser. The low voltage is grounded. Remove the low voltage (likely 2 wires) at the condenser and wire nut the wires leading inside. With an insulated screwdriver manually push in the contactor and be sure both compressor and fan run. Then replace fuse and turn power on to air handler with a call for cooling. Obviously the outdoor unit won't run because you unhooked the low voltage but if fuse doesn't trip then it's likely the contactor. Good Luck

Keeps blowing 3 amp fuses when i turn the air conditioning on.


Ok, If 3 amp fuse is blowing in the air handler unit when switch is turned to cool check to see if outside unit jump starts and stops when this happens. If this is the case wiring is fine check main relay in outdoor unit. There will be a spring contact on main relay (Black relay close to where wires come into unit), check for corrosion or carbon build-up on little round contacts. If you can clean contacts with a small piece of sand paper. Make sure all breakers are off before removing cover! You might have to remove relay in order to clean it. Make sure you write down exact locations of any wires you remove. This should fix the problem.

What does error code p8 mean


P8 means Abnormality in outdoor unit.
Check:
1) Wrong wiring of indoor/outdoor
connecting wire
2) Reversed phase
3) Protection device is working
4) Damaged outdoor coil thermistor

Solution:
1) Check the indoor/outdoor connecting wire.
2) Change the connection of electric wiring.
3) Check the protection device.
4) Measure the resistance of the outdoor coil thermistor.
If the resistance is normal, replace the
outdoor controller board

Hope, helpful.

Fuse on control module blows when calling for cooling


Yes.
Disconnect the the red and the yellow wires at the outdoor unit. Then replace the fuse and turn on the power.......see if the fuse blew. If the fuse blew, your problem is most likely a short in the low voltage wiring. Check for crimped or damage wire or wire insulation and repair as necessary. If the fuse is okay, then the problem is within your outdoor unit.......again inspect all wiring for any damaged insulation or crimped wiring.
Check these items and let us know.....we can guide you further after you perform these checks. :-)

Goodman ck36-1a not turning on


ok, you have turned the thermostat to the cooling setting? and turned the temp setting down, so the blower comes on.
As far as the outdoor unit, first thing to do is check the breaker in the electrical panel, next check the disconnect box, that should be located on the wall near the outdoor unit.
It will have a breaker or a set of fuses, that need to be checked, if it has fuses, they have to be tested with a ohm meter, and you cannot tell anything about their condition buy looking at them.
Good Luck.

Heat pump not running


Depending on the age of the unit it could be several things, does it have a circuit board? Contactor could be bad, freon leak if it has a low pressure switch, burnt wires, connections, etc. Do a complete visual and check for 24 volts, does the indoor unit run? Transformer may be bad.... No indoor unit - no outdoor unit, most of the time the outdoor unit gets its 24 vac power from the indoor unit which runs them both, look for fuses (like car fuses)..

Central air conditioner doesn't turn on... Any suggestions?


If the compressor turns off and won?t come back on during a very hot day, the unit may have built up a high "head" pressure and the high-pressure limit switch may have tripped. This is usually located right inside the access panel on the compressor unit. Simply push the button to return it to operation. If your central air conditioner doesn't go on automatically: 1) Be sure the thermostat is set to "cool" and set below room temperature. 2) A central air conditioner should be on a dedicated 240-volt circuit; check the main electrical panel and any secondary circuit panels for a tripped breaker or blown fuse. If you find the problem here, reset the breaker or replace the fuse. 3) Make sure the furnace power switch is turned on and that the outdoor condenser's power switch, mounted on the outdoor unit, hasn't been shut off. Also be sure the 240-volt disconnect next to the compressor (in a metal box, usually mounted on the house wall) hasn't been shut off. 4) Turn off the power to the air conditioner and check the thermostat. 5) Remove the thermostat's cover and unscrew the wire from the Y terminal. 6) Turn the power back on. 7) Holding the wire by its insulation, touch the bare end to the R terminal and hold it there for about 2 minutes. If the compressor kicks on, the thermostat is faulty; replace it or call an air conditioning technician. If the compressor doesn't go on when you hold the two wires together, turn the power back off and call a service technician.
