Have you checked location of probe for return air? Remove filters and find probe to make sure it is about in the middle of flow of return air. Let me know what you find.

SOURCE: fan cutting on and off every 5 mins

The only thing that is going to but the fan off is the thermostat. When the fan stops, immediately check the thermostat on the wall. See is there is power between the B terminal and the GH terminal. If none, then replace the thermostat. If there is, then replace the control board in the AC. That means that the fan relay on the printed circuit board is weak.

SOURCE: My air conditioner keeps icing up.

Don't forget to drop ceiling assy enough to be sure that their are no restrictions or blockages on the forced side going into duct work etc, as well. Feel for cool air leaking across in to return air box as well.

SOURCE: our ac gets cold then cycles off and does not blow

Look from inside you should see a filter and behind it a coil, the filter and the coil should both be clean, (very clean) might be all that's wrong.

I have a Frigidaire Gallery refrigerator. The freezer is not cooling enough to keep frozen. It is blowing cold air and the refrigerator part seems to be working.


If your freezer is cold then you may have a defrost cycle issue. There are typically three components for the defrost cycle. Heater bar, thermostat and timer. If the defrost system fails ice starts to build up in the back of the freezer until it prevents cold air from getting into the fridge. When I took off the back panel inside my freezer it was a block of ice. You can melt the ice with a hair dryer and order new parts.

What is the problem now? Please can you help?


If you turn on your AC on one day and nothing happens, you may be dealing with a major component failure. Your vehicle's AC system consists of a compressor, condenser, evaporator, expansion valve, a series of tubes and several fans/blowers. If either one of these components fails to do their job, it may result an entire system failure. For example, if the evaporator blower motor burns out, you will get little to no airflow through the vents.
Most modern vehicles also have safety mechanisms that may prevent a component from engaging if the pressure is low in the system due to a refrigerant leak. Refrigerant can leak for many reasons, including undone welds, loose connections, corrosion, physical damage from road debris, etc. Look for oily stains underneath your car, as they may indicate a leak. If you suspect a refrigerant leak, take your car to General Automotive. We will test the pressure and use special dyes to pinpoint the leak.
Warm Air is Coming Out Instead of Cold As you get in your car and turn on your AC, you probably expect it to be blowing hot air for the first minute or two until the system cycles through enough to cool it. But what if the air never gets cold ? Or maybe it it gets cooler, but not cold enough ? No, your car didn't get confused and turned on heat by accident. There is likely a problem with your condenser.
A condenser's job in a vehicle is to cool the warm refrigerant that was used to make the air cold in the evaporator. A condenser has coils and a fan to push the air through the coils and thus cool the refrigerant. If the condenser coils get dirty or clogged, or if the fan fails, the refrigerant won't be cooled completely, so the air will come out warm. It's best to take your vehicle to an experienced AC Repair professional to troubleshoot this problem if you don't know your way around under the hood.
Cold Air Blows Intermittently So you went for a road trip or a long drive, and after 30 minutes of driving realized that your AC suddenly stopped working or switched to blowing warm air. The cold air returns shortly, and the cycle repeats itself for as long as you are driving. What's wrong with your car?
Intermittent cooling is often caused by the components of your vehicle's AC system freezing up. Typically an iced over evaporator is the culprit. An evaporator covered in ice can't cool the air, so you would have to wait until the ice melts, which is why the cold air eventually returns. There may be numerous issues causing the icing-from a dirty cabin air filter to a blocked evaporator drain or an overcharged system. Look for puddles of water under your car-this could be a sign of a freezing problem.

I have a brand new (2 days) Frigidaire Gallery series, 23CU side by side that is not making enough ice. We are getting water from the door, the ice maker will only drop about 3 times in 24 hours. the...


Good day,
Light usage in a cool kitchen will reduce ice production substantially.
When the ice maker harvests, it turns on a calrod unit located on it's bottom, that frees the cubes, and as well the heat from the calrod heats up an internal thermostat in the ice maker to a temperature in excess of 70 degrees.
Then it stays at rest, until the cycle thermostat reaches 12 to 14 degress and then performs another harvest cycle.
If the machine runs little, and the fan in the freezer is not circulating cold air, the harvest times will be extended.
Turning the freezer colder will always help.
There is a possibility, the thermostat in the ice maker is out of calibration, and the ice maker needs replaced. But try the settings first, and give it a week or two, before calling for service.
You have a lot iof time under warranty to resolve this issue.

Thank you for using FixYa.

Air conditioner doesn't blow cold air. Continues


If the a/c fails to continue to blow cold there could be a few problems you can look for. First once you activate the system check to see if the compressor kicks in. You will hear the compressor humming . Once the a/c quits cooling go and see if the compressor is still running. If its not running its probibly gone into thermal overload (compressor overheated). If that is the case then you need to check to see if the coils are icing up if they are icing up then the problem is with 1) air flow restriction filter dirty, coils dirty simple repairs there replace filter, clean evaporator coil with a coil cleaner that can be purchased at a home repair store cleaning the condensor coil the same. 2) system is low on freon in which case the system will need to be recharged. Also, If you have a digital thermostat replace the batteries that may also be of some help. Good Luck on repairs

Side by side: freezer temperature fine, fridge too warm


sounds like your auto defrost isn't working. my maytag does same thing. the cooling core in the freezer is probably iced up. when it becomes solid ice no air(or very little) can pass by, leading to too little cold air reaching the fridge. you can try to cycle the temp levers(usually doesn't work) you can manually defrost the freezer. pull the cover off the back(inside freezer) and use a blow dryer. not sure how much parts are for whirlpool. hopefully this is just a one time thing. there are tests you can find to check some of the parts.like the heat element for the defroster, just search for the tests.

Not blowing cold air


Most likely evaporator coils are iced near solid...few hours unplugged would have helped just a little...needs major defrosting though.
The automatic defrost cycle will never fix it when it gets this bad...if it's still working yet.

I have one of these and have had to use heat gun/ hair dryer more than once to defrost it.

Probably the cause...which will need fixed or it will do it again sooner or latter...is the melted frost/ice goes down a little drain tube and dumps into tray to evaporate above coils...this tube gets plugged first with dust and then when melted frost drains and stands in tube the tube get plugged with frozen water.

You see it is important to unplug or fridge will self destruct.

1994 Previa A/C problem


Look to see that the A/C condensate drains are working. You should see water dripping out from the front & the back whilst the A/C is running. If no water; clean the drain tubes. Also, you need to be running the A/C on the RECIRC mode (the little car with an arrow doing a u-turn inside the car); if not, you are air conditioning outside air, and the unit is icing up from too much humidity. Sort of like running your fridge with the door open...
If neither of those items correct your issue, you may need to replace the A/C thermister; but, that is a very rare failure.
