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.

SOURCE: My AC unit keeps freezing

Operate your air conditioner with the fan in the on position. But first turn the fan on, turn the temp up or shut the cooling off. Your coil is more than likely frozen over. At night when outside temperature drops the refrigerant pressure and temperature in the system also drops. This action can cause icing of the cooling coil, with the fan in automatic everything shuts down at the end of a cooling cycle. Thus no air movement to melt ice on previous cooling cycle.

SOURCE: Small pipe running from outside unit freezing up

SOUNDS LIKE THE FAN SPEED MAY BE TO LOW SO AS THE AIR GOES THROUGH THE COIL IT WILL START TO FREEZE HAVE SOMEONE CHECK THE FAN SPEED MAKE SURE IT IS ON HIGH ALSO MAKE SURE IF THAT IS THE ONLY FILTER ON THE SYSTEM

SOURCE: central air freezing up

Low freon causes this problem. It could be the compressor going bad, but 99% of the time it is that the freon is low, have it leak tested and also have freon added

SOURCE: Fujitsu ASU12C1 is freezing up

unit is freezing up because it either has too much freon or not enough. the pressure should be checked on both the low and high sides and corrected.

SOURCE: freezing up, home ac unit no air flow after running a while

A low freon level in the unit can cause them to freeze up. Are the fins behind the filter clean?

Freezing ricotta cheese

Freezing ricotta cheese is possible, but it can change the texture. The moisture content in ricotta can cause it to become grainy or separate when frozen. However, if you still want to freeze it, here's a guide:
  1. Drain Excess Moisture: If your ricotta has excess liquid, drain it before freezing. You can do this by placing it in a fine-mesh strainer or cheesecloth-lined colander over a bowl in the refrigerator for a few hours or overnight.
  2. Portioning: Divide the ricotta into smaller portions if you're not planning to use it all at once. This way, you can thaw only the amount you need without repeatedly freezing and thawing the entire batch.
  3. Freezing: Place the ricotta in airtight containers or freezer bags. Ensure to squeeze out excess air from the bags before sealing to prevent freezer burn. Label the containers with the freezing date.
  4. Freeze Quickly: Put the containers in the coldest part of your freezer, and ensure they freeze quickly. The quicker the freezing process, the better the quality upon thawing.
  5. Thawing: To thaw frozen ricotta, transfer it from the freezer to the refrigerator. Slow thawing helps retain more of the texture. Avoid rapid thawing at room temperature, as it can lead to a watery consistency.
  6. Use Promptly: Once thawed, use the ricotta within a few days for the best quality. Try using it in cooked dishes like lasagna, stuffed shells, or pasta sauces where the texture change might be less noticeable.
Remember, while freezing ricotta is an option, the texture might not be the same as fresh ricotta. It's best to use frozen ricotta in recipes where the texture change won't significantly affect the dish.

Armana APN14K-E portable AC freezes up

Lack of air flow or a lack of refrigerant are the two primary reasons why coils freeze. Clean the filter and the coil, if frost continues it is likely low on refrigerant.

Hi there,any advice please on frozen pipes..no water at all,no toilet,shower..can i use my central heating?...im forozen..

You will need to get to the pipes with a torch or heat gun and melt the ice out allot of times when the pipes thaw out you may have busted pipes with long cracks running down the pipe. The best way to handle this is to turn off the water to your house and inspect the pipes I would go and purchase some heat tape and cover all the pipes in exposed areas (crawl space, attic, and basement) and let the heat tape thaw out the pipes. after about an hour turn off all your inside valves ( tubes, shower, sinks and the cold water to the water heater) then turn your water back on and watch the meter at the street if it spins then you may have busted pipes.

1- Turn off water at the meter by the street.
2- Thaw out pipes with torch or use the heat tape.
3- Close all valves in house including cold water valve at the water heater.
4- Turn water back on at meter and mark on the meter where the hand is now then watch to see if the meter is turning.


The heat tape will keep you from freezing pipes in the future.


Hope this helps..............

My icemaker motor keeps freezing up. I can take

check your ice machine to be level, most are installed level, but then the installers tilt the machine back just a bit to assist in door closure, if your ice machine is even slightly out of level, it will over fill and clogg the motor the very first ice cycle

Unit freezing up

It will not hurt the unit if you let it thaw out and then run it again. However, if you keep doing this on a regular basis, you can burn out your compressor. What are the conditions that the unit is being run under that is causing it to freeze up? Make sure that you run the unit on high cool on warm days so that it will not freeze.

Hope this helps,

Jeff

The coil in my byrant furance is freezeing up , my ac has been running for hours and i noticed that the house was not cooling down. when i checked the furance i noticed ice on the outside of the coil above...

Low on refirgerant, or dirty coil, or it was run on a cold night. Either way, the only way to take care of it is to start by running the fan only, and shutting the cooling off. This will melt the ice on the coils. It is going to make a mess. Have the unit serviced if it is not dirty, if it is dirty clean it with an approved cleaner. Your local hvac repair shop should be able to recommend a good cleaner.

Central heat and air freezing up

It is not freezing because it's cold outside,It is freezing due to a problem.
It needs to thawed before it will work,

1st:Check or change the filter if need be.
2nd:Make sure none of the vents are blocked off(especially the return)
3rd:The only way to thaw it when temps are low outside,without being out in the weather is to turn on the air conditioner,You will need to use other means to heat your home until it thaws.

and Please if you use the stove for heating,don't fall asleep with it on.

Food is freezing

usually there is an adjustment at the back for the difference between the fridge and freezer compartment. Often is just a vane that blocks freezer air, too much air would freeze the food. Normally you set the fridge thermostat for a normal food temp, then adjust the air to keep the food warmer than the freezer.

Humidifier coils freeze

I believe a dehumidifier is supposed to operate in temps above 60 degrees. Even though your house is warmer than that, the air entering the dehimidifier may be getting into that range due to it being on a basement level etc. This is perfectly normal and is not a malfunction with your humidifier.

Your options are to either place the dehumidifier closer to a heat source in order to keep the air which is entering warmer. (I've even heard of someone placing a light bulb in front the unit during winter to warm the air slightly as it enters). Because the dehumidifier's coils get cold in order for it to collect moisture from the air, if they are freezing, giving the unit a rest for a few hours every few hours may allow the coils to thaw in between and prevent them from reaching freezing temperatures while running. You could use a timer to accomplish this, but you'll want to insure that it's a commercial grade timer in order to handle the electrical draw that the dehumidifier requires.
