My central air conditioner was working fine but the power went out for about 2 hours and when it came back on, my air pump runs and the air conditioner fan is running but it blows warm air. What gives?

Mcdevito75 here, Your A/C units control board is most likely transisterized or computer built, in which case when power went out so did the memory in your A/C control board. Simply shut down your A/C unit, re-start and make adjustments again for your comfort.

Why does my central air keep freezing up?


An air conditioner freezing up is either low airflow or low on refrigerant. If the filter is clean, then check the refrigerant level, blower running at proper speed, make sure indoor coil is not dirty or restricted. Make sure that the duct outlets are all open and some have not been closed.

Outside fan not running, inside unit running fine. Compressor was running this morning, but no longer. Replaced fan motor, turned power back on, now fan or compressor not running. What else can be checked?


Hi,
There may be a manual reset high limit... look for a red button on a round part hooked to the small copper line and push it in hard...
Also the compressor may have kicked the overload and needs a few hours to cool and it reset, that is interanl insdie the compressor.
Contactor may also have went bad...


Here is a tip about troubleshooting your air conditioner...

Central air cond. was working fine 5 hours ago it went off and wont come back on. the thermastatis not lit up. it does nothing.when you try to turn air on, nothing happens at all


First ,you should verify thermostat has good batteries.secondly ,you should check to make sure the circuit breaker isn't tripped. If both of these give no results and you feel comfortable digging around the unit yourself, you will have to access the sevice panel on the outside unit to verify voltage from transformer. You should check the secondary side of transformer for 24 volt ac, as this is what feeds power to your thermostat . Hope this helps

Furnace runs on heat, air conditioner does not


If you have a Gas furnace in the Attic then the answer is yes. The outside condenser will not run if in fact you have a gas furnace.

It turns off


The e1 code is a demand to clean the filter. It means the unit has been running for 720 hours. It does not mean anything is broken...unless it hasn't been running for 720 hours. That would mean the "clean the filter" timer is broken! There are 2 reset methods.

1) Unplug the machine. Hold down the power button while plugging it back in and wait until it beeps (for about 5 seconds). Let go of the power button. Unplug the machine again, then plug it in and try to use it as an air conditioner.

2) Unplug the machine. Hold down the Mode button while plugging it back in. Keep the mode button pressed until it beeps (for about 3 seconds). Let go of the mode button. The machine will start. Turn it off by pressing the power button. Resume trying to use it as an air conditioner.

If neither of these work, the "clean the filter" timer is broken and needs replacing.

The error code is saying E1


1. Power down the air conditioner using the "power" button on the front
panel.
2. Unplug the air conditioner from the wall socket.
3. Hold the front panel "power" button down and plug the air
conditioner in. Continue to hold the power button down as the machine
goes through a brief test sequence (fan & compressor each come on
briefly, etc). There is a "beep" sound at the end of the test sequence,
and the machine will be off. At this point, you can release the power
button.
4. Unplug the air conditioner.
5. Plug the air conditioner back in.
6. Congratulations! You should now be able to operate the air
conditioner normally for another 720 hours, but only if you followed
the instructions above EXACTLY.

If you doubt the veracity of this information, or it does not work as
expected, you can get it directly from the source at:

1-800-237-4277

which is the Sharp customer service line. But, you'll need to call
between 7 AM and 7 PM US Central time, and have your model number and
serial number ready.
