Lots of possabilities. Could be fuses or circuit breakers. Could be tripped pressure safety switch inside unit. Could be failed run capacitor. Could be problem with a control board. Recommend having a qualified professional check the system out after you check breakers and fuses.

Is a small amount of brown moisture coming out of A/C w/cold air & slightly squeaking fan upon yearly startup on kenmore model 253.70101 acceptable : should i run it longer than 1 minute.


Brown is rust.
Painted metal outside for 2 yrs eventually rusts (ergo: brown drips) The fan is exposed to heat/cold/wet and the sintered bronze bushings may have lost their lubrication and/or the shaft is corroded, causing squeaks. Take the case off and try to lube the shaft bearings with oil, not WD40.

How come my AC is on but the air coming out is not cold?


Check the refrigeration lines coming off the outside unit. One should be very cold and one relatively warm. If one is not very cold, then the compressor is not working. Usually you can hear it when it is running. The condenser fan in the outside unit should also be operating. If the compressor and fan are operating, but the refrigeration line is not cold, you probably have a refrigeration leak and have lost the coolant. You will need a service tech for the repair.

I have a ten year old carrier heat pump unit. I recently replaced the indoor tstat. the outside contact and the transformer. Had a tech put freon in the unit also. I have to problems one is the airflow is...


Two things are the most likely culprit. First check ytour inside coil with the unit running for 10 minutes or more and see if the coil is sweating there should be water running off of it. Also after one hour is there ice forming on it. These problems are lack of air flow which is caused by restricted air flow caused by a dirty filter dirty coil (which you have already taken care of) or your blower motor may not be kicking into high speed. Your motor will start and then after it gets to a certain speed it switches to a high speed. After running only 15 minutes if your blower motor is hot to the touch. Be careful some will cook an egg. If it is hot not just warm it is bad and needs to be replaced. Also if the fan is not running properly you can not get reliable readings with your gauges when adding freon. So if this is the problem then you may have to have the units freon cked again. If the line is not sweating at the outside unit where it goes into the unit the freon pressure is not right. The larger copper line will be cold and sweating the small line will be hot to the touch when the system is balanced and running properly. I hope this helps

Cant keep cool


You need to check that tour filters are new. Then check that air is coming from the vents and is at least 15 degrees cooler than room temp. If no air coil is frozen, or blower motor and run cap are not working. If frozen than turn system to off and fan switch is on until you feel air through vents.
You'll need to make sure the outside unit is runing and the larger copper line is cold like a can soda. If it's cold but is freezing up, it needs to have a charge added. If its running but not cold and the fan is not running or the compressor isn't running it could have a blown capacitor. If its not running at all check. the circuit breakers and reset them. And a good idea to keep the outside unit washed with water,and that it is clear of weeds and stuff.

My outside a/c condensing unit's fan runs, but inside vent air is not cold. compresser may not be running. inside vent air was cold last week. Janitrol ckj361ab is model # of outside unit.


Start the unit and go outside to see if the insulated pipe is sweating or cold, hot air should be discharging from top of outside unit. Since the breaker is not tripping, my best guess is the compressor is not operating. You might have to replace the capacitor.

If you can hear the compressor operating, then most
likely needs refrigerant

I have a 20 year old Trane heat pump. Outside


Yes, you will want to put the unit into cooling mode to help assistance with the ice melt.

If you can, block off the outdoor coil or disconnect the outdoor fan motor. This will assist in raising the discharge pressure and temperature and thus, it will melt the ice quicker.


Or, if you have the capability, you can take a garden hose around to the unit hooked into hot water and melt the ice that way.




If your control board is messed up, why aren't you replacing it?
