    I tried turning the fan from auto to on and it did not run. Out of curiosity I turned the heat on and got it to kick in and the fan works with the heat. I don't know what a jumper is and might have to break down and call a professional.

  • pepsi_chic18 Jul 06, 2010

    The fan kicked in! All on it's own. I wonder if the record breaking heat has anything to do with it. Praying the A/C unit does the same...

    I'm not sure what the insulated suction line is... but I don't hear anything running.

Turn your fan from auto to on, your fan should run. If it does not turn on you have a 24volt problem.
Go down to furnace and remove thermostat wires at control board. Install a jumper between R and G. Put door back on and turn furnace on. If fan comes on you have a wiring or control issue, If fan does not come on iot is possible that a little 3amp fuse located on the board is blown or your tansformer is bad.
Remove jumper bewteen R and G and put it between R and Y. Put door backon and turn on power. If your AC starts, you have a wiring problem.
If it does not start, did you check to make sure the breaker or fuse is not blown on the air conditioner?

    It could be that your thermostat is not wired to have fan on operation. Turn it to cool and the fan should come on as well. It

    does not matter what the outdoor unit is doing.

    If the fan comes on in cool mode then at least you know you dont have a control issue and the problem is outside

  • Frank Bryant Wetzel Jul 06, 2010

    Go outside as you should be able to hear the compreesor run. Also the insulated suction line should be cold.

How to get Goodman air conditioner to pump cold air in after changed filter?

First, remove the air filter and check the coils above or immediately adjacent to the location of the filter. They may be clogged. Use a soft brush to remove lint, hair and grime. BE CAREFUL TO NOT BEND THE DELICATE FINS ON THE COILS. If they are clean then if your AC is a forced air system (whole house) do the following.

Is the compressor running? That is the big box unit outside of the house. You may have to turn it off at its breaker (separate from the air handler where the filter is located and usually outside the house near where the meter is located.) Leave the breaker in the off position for 20-30 minutes before turning it on again. Set your thermostat to 66 degrees or there abouts before turning the breaker back on. After turning the breaker back on, if the compressor does not start up within a few minutes, then it is possible that one of the startup capacitors is defective. If you do not feel comfortable working around 230 volt electrical systems, call an AC repair shop and have them do a system check.

Is the blower coming on inside? If it isn't, try tripping both breakers again. If the blower is working, your thermostat may be timed out or the air cond may have a timer in it that will keep it from coming on for a few minutes.

If none of the above work, make sure you didn't pull any wires off when you pulled the filters out.

Where is the reset button on an Amana ASZ14 unit?

I don't think the Amana ASZ14 Heat Pump has a reset switch, but you can still reset it by resetting the power (when it's not running... turn your thermostat OFF first).

To reset the power, locate your circuit breaker box. There should be a double-breaker for the Heat Pump and another double-breaker for the Air Handler. Turn them both off for at least 2-3 minutes. Then flip them back on and turn your thermostat back ON.

You're thermostat may also have a RESET button that you can push. I have to reset mine every time I change the batteries in it.

Air conditioner keeps flipping the breaker

Could be a lot of things. About the only thing you can do besides calling a service tech is to 'make sure your coil on the condenser (outside) is clean. This coil can be cleaned with a water hose, but you need to make sure you have all electricity turned off.

Turn off the breaker on the outside unit (this could be a fuse block that you have to pull out) and make sure you have your inside thermostat in the off position.

Once you are 'absolutely sure' that you have all electricity off - you can wash the coil with a high pressure hose. Just make sure that both - the inside and outside of the coil is clean; you may have to disassemble the unit a little bit, i.e. take the top off or one of the sides, etc.

The only hope you have - is that the coil is clogged and causing the compressor to overheat and go off on amp overload. It's possible this is the case - but I also suspect the compressor is electrically breaking down which is not connected to the condenser coil being dirty, in which case you will need a service tech and may be faced with some expensive repair. Let's hope this is not the case.

So - it's worth a shot to wash the outside coil.

Not to be 100% negative - it's possible it's something minor and when a service tech looks at it - it could be a fairly cheap repair bill.

Good Luck!

I had a 14 seers Trane installed 18 months ago. The thermostat goes blank and the system doesnt come back on until I flip the breaker or disconnect power to the ac.

try replacing the batteries in the thermostat on your wall. probably has 2 AA's this may fix it if not may have bad or old wiring from tstat to main indoor system. when you had a trane installed did they change the air condition components only(likely) or did they put in new furnace, new wiring, new t-stat, a full install?

Unplug unit let set till cool then turn on motor has heat trip button that will pop out so it wont over heat, It should pop back in when it cools off. Make sure filter is clean and condenser is not iced over by high humidity. If unit still wont come on check house fuse or breaker it should be on a circuit by it's shelf, flip it off and back on so it is closed all the way.

Air Condition will not come on. We have tried to flip the breaker but no success. The fan on the air condition inside and on the outside is not turning.

If you have one of those new digital thermostats try changing the battery. If your air conditioning is run through a central heating system the power must be on to the furnace. 24 volt control circuit gets its power from the furnace in this kind of case.
