You are going to have to increase the amount of heat absorbed by the evaporator coil on the indoor section of your system. First change the filter. Second turn the power off to the outdoor section and leave the indoor fan running until all the ice on the evaporator coil has thawed this could take a few hours. Third you need to verify that you are getting adequate airflow across the indoor evaporator coil and the outdoor condenser coil both fans should be spinning at full speed and airflow should be unobstructed by dirty coil fins or debris Hopefully after you've done this you will have cold air blowing inside and the larger of the two lines entering the unit outside will be cool to the touch but not frozen or even frosted regardless of run time and the small one should be the slightly warm but not hot. If the larger line continues to freeze then it could indicate a number of problems but essentially your condensers cooling capacity is outrunning your evaporator coils ability to absorb heat from air stream circulating in your home.Hope it works out for you GL!

The air conditioning fan outside the house is showing frost on the coils, what is the problem


Are you using your Air conditioner as a Heat Pump (Making heat in the house)- or as an Air Conditioner (making COLD air in the house.)

If as a heat pump, then remember-- that the WARM coil is now inside the house-- and the COLD one is outside-- So, if it is COLD outside, there is not enough HEAT out there, to keep the coil from going below freezing-- The unit may have to be turned off, and allowed to defrost, if you want more heat from the Heat Pump-

Let me know if this helped

How a Central Air Conditioning System Works
amn_howac.jpg


Facts:
  • The typical central air conditioning system is a split system, with an outdoor air conditioning, or "compressor bearing unit" and an indoor coil, which is usually installed on top of the furnace in the home.
  • Using electricity as its power source, the compressor pumps refrigerant through the system to gather heat and moisture from indoors and remove it from the home.
  • Heat and moisture are removed from the home when warm air from inside the home is blown over the cooled indoor coil. The heat in the air transfers to the coil, thereby "cooling" the air.
  • The heat that has transferred to the coil is then "pumped" to the exterior of the home, while the cooled air is pumped back inside, helping to maintain a comfortable indoor temperature.
  • Central air conditioning can also be provided through a package unit or a heat pump.

Benefits:
  • Indoor comfort during warm weather - Central air conditioning helps keep your home cool and reduces humidity levels.
  • Cleaner air - As your central air conditioning system draws air out of various rooms in the house through return air ducts, the air is pulled through an air filter, which removes airborne particles such as dust and lint. Sophisticated filters may remove microscopic pollutants, as well. The filtered air is then routed to air supply ductwork that carries it back to rooms.
  • Quieter operation - Because the compressor bearing unit is located outside the home, the indoor noise level from its operation is much lower than that of a free-standing air conditioning unit.

A Great Tip For Saving Money


While everyone usually remembers to change their AC and Heater filters, no one thinks about cleaning the heating or cooling outdoor coil. If you have an outdoor unit for heating or cooling, those coils need to be clean too!!

The principle of an HVAC unit is to remove heat or cold from your home to make sure you have a comfortable temperature inside.

If you have a gas furnace, your good to go in the winter. Make sure you change your filter every month and you should be able to keep your home at an nice temperature for you and your family. BUT, if you have an air conditioning unit hooked up to cool your house in the spring and summer, you need to do a little maintenance every spring to make sure you get the most out of your unit and save money. The same principle works for a heat pump, so i'll break it down for each unit.

1. An air conditioning unit that has a gas heater works just like it sounds. In the winter, your thermostat will tell the heater to turn on. You will have your burner running until the fan switch in the heat exchanger gets to the right temperature to turn the fan on. This is so you don't have cold air circulating through the house. Cooling on the other hand works a little different. If your thermostat calls for cooling, your fan will turn on right away and your condensing unit outside will turn on. What you AC is doing is removing heat inside the house and putting it somewhere else. That;s where your condensing unit comes in. The heat you removed inside the house is transferred outside where it is compressed and cooled through the use of the outdoor fan.

Now, imagine if this outdoor unit has dirty coil. You are no longer able to remove the heat from the house because it's not able to be removed because of a dirty coil. This means a huge loss in cooling capacity, higher running amperage on the compressor, and your electric bill being alot larger than it needs to be. I'll have the solution after I address the heat pump.

2. Now, the heat pump. It is basically an air conditioning unit that can reverse. In the summer, the outdoor unit will blow hot because of the heat it removed in the house. In the winter, the outdoor unit will be blowing cold because it is using the heat outdoors to add heat into your house. While this sounds weird, it's engineering at it's best. In the winter, heat is able to be removed from very low temperatures and your able to transfer heat into the house because you have a compressor in your unit. It does what it says. It takes a low pressure-low temperature refrigerant and compresses it into a high pressure-high temperature refrigerant.

Now, getting to the coils of both units. You need to clean the outdoor coil on both units every spring to make sure you have a clean coil. In the long run, this will allow the unit to expell the heat gained from the house and in the long run will add life to your compressor and save you money.

On the heat pump, you'll also need to clean the coil every fall. This is because if you don't, you could have a problem with freezing your outdoor coil. If you can't remove the heat from indoors, you will slowly turn your outdoor coil into an icemaker!!

So, based on what you have, turn the power off to your outdoor unit. Spray very good with a degreaser such as simple green and let it sit for about a half an hour. Then, grab your hose and wash out the coil. You'll be amazed what comes out. Let it sit for a coup0le hours to dry out, then turn the unit on.

This will not only extend the life of your compressor, it will also save you money in the long run!!

Amana Cooling Condensing Unit fan stops spinning after 15 mins


Capacitor, dirty condencer coil causing the motor amps to run too high. But most likely worn bearing on blade side of motor causing it to pull to one side causing it to over heat and shut down. Sleve bearings should have no side play.

Central air/heat pump not putting out cold air


I have some things for you to check. If you look at the outside unit the lines going into the house. Are they frozen? Have you had any yard work done, the reason I ask is they could have accidentally cut or pulled out the thermostat wires to the ac unit. Also, inside check for the same thing, frozen lines. Also, you may want to check the drain coming from the inside unit, it may be clogged.

Not blowing cold air


Your in house core could have frozen over. check the core inside the indoor blower unit. it may have frozen over. this will interrupt the cold air function.

Blower Turns off if ac unit comes on. No air coming through vents


This only could 1--2 things, a bad circuit board fan relay or bad thermostat. To check for bad thermostat, take off the front cover to reveal the 4-wire terminial and jump the red-wire (power)-cool,(yellow -y or blue)--- green--fan white-(heat)..........red to yellow-or y=cool. Thank-you-very-much!

Air handler only blows air for 3-5 minutes before shut off & not cycling frequently


Sounds like it could be a very weak run capacitor on the blower motor. Run capacitors are sized specifically to the needs of the motor. When a run cap gets weak, the motor trys to compensate for it by drawing more power. More power draw = more heat in the motor, then the motor will overheat and shut off to protect itself. When the motor cools off it will automatically restart and run until it overheats again. Keep in mind that I am a technician that normally diagnoses equipment in a hands on manner. There are many practices and concepts that transcend all air conditioning systems but it is a constantly evolving industry. I live in south eastern WA and I don't see Amana units except as window units. It is possible to have something else causing this problem (faulty thermostat, failing thermal relay(if used), problem with electronic controls(if used)) there are a lot of potential variables
