It could be a breaker has tripped or the batteries died in your thermostat if it does not have a common wire connected. Is the unit not working at all? What type of unit do you have? (i.e. gas furnace, heat pump ect.)
Most units have a breaker inside the panel near the blower motor that you may overlook seeing as how it is not in the main panelbox with all of the rest of your breakers. I would start there and follow the 24volt wires back to the thermostat. The problem is somewhere in between the blower motor and the thermostat. Good luck!

The thermostat clicks but nothing else happens, no a/c will come out or no heat [I tried both]


(I have this model at my home). If you switch it over to emergency heat and nothing comes out then check the breakers behind the panel for the air handler (inside unit)
There may be other issues, mine had a sequencer which had come apart. The newer
sequencers have a retainer clip to prevent this. It is located under the galvanized cover inside the indoor unit next to the transformer.

Also check the breakers at the main panel (there should be two double breakers, one should be a 20 to 25 amp for the outside unit and the other should be around 70 amps for the indoor unit). Fully reset them after performing checks described later. .
If your outdoor condensor compressor is failing (as mine did), it will trip the smaller breaker, if your indoor unit has a short or other problem it will trip either the 50 or the 70 amp breaker. Make sure you turn off all breakers before inspecting.

One last thought, if your thermostat has battery backup and the transformer has failed, you will still hear the click but nothing will operate
since the 24 volt transformer operates both the indoor and outdoor units.
It is located under the galvanized cover inside the indoor unit.
(I would suspect this if all else appears normal with no breakers tripped). A universal transformer is around 8 to 12 dollars make sure to use the 240 volt wire and the COM
when installing it. (there are several wires for various input voltages on the primary).
they are available at any HVAC parts store. Power off to all sources before repairs.

My goodman furnance will not bow out air only the fan works . what should i do


Check all the easy things first. Check that all the settings on the thermostat are correct for AC. Does the AC unit run? If not check the electrical panel breakers to see if the AC unit breaker is tripped. If it is tripped, reset it. If it continues to trip, call are reputable service company. There are little or no items for "do-it-yourself" unless you have the training and equipment to service AC. Good luck.

Heatpump blow out air put not warm


We will need to check and see if the outdoor unit is running when thermostat is set for heat. If not, check the circuit breakers and reset if tripped. Also, check to ensure the high pressure switch isn't tripped (you will likely need to open the panel to see the HPS, it will have a red button on the top of it.

A/c unit not working. Have thermistat set on 65 and temp. in house is around 85. check the breaker box for the house and it have not tripped


You must make sure that there is power to both the inside unit and outside unit. Is the room air blower blowing? If not you have either a plugged filter, iced up coil, the access door is not quite closed or there is no power to the unit. Is the outside unit fan turning? If not, you either have no call from the thermostat, the fan is broken or the unit has no power to it. I would turn off the breaker to the inside unit and switch the breaker near the outside unit to off and let them sit idle for 5 minutes. Switch both breakers back on and chect to see if the outside unit turns on. Then check the indoor unit and see if this starts blowing. Let us know what you find.

Air conditioner not working


the outside condesor unit is not coming on for a number of possible reasons. First check your breakers for a tripped breaker, even if they appear on, turn the ac breakers off and then turn them back on. if after this, turn on the thermostat, outside you should here the contact switch on the condensor unit humming. if still no power, check for any breaks on your wires going in from the house, still nothing give a call back

Most likely the transformer is shot on the air handler. To test this go to the thermostat and move the selector to fan on, if the fan blows it's not the transformer. Let me know. THX RepairUSA
