SOURCE: American Standard blower will not run

Sounds like motor has failed. If the red light is blinking it may be telling you what is wrong by the number of blinks. It maybe locked out for some reason or loose wire. Try turning off breakers to inside unit for 5 mins and try again, this may reset unit. But it sounds like a bad motor or circut board. Try running with stat in on position instead of auto in cooling mode.

SOURCE: Is there a system mismatch with an American

This must be a heat pump? Sometimes the unit can be more efficient with this combonation. What you are probably hearing is the reverse direction of the
refrigerant going back through the liquid line.

If in cooling sometimes you can hear a gurgling sound going through the expansion valve, sometimes
this is a sign of low refrigerant or the system is fine..

If you recently had the outdoor unit replaced and noise is an issue, check to see if the unit has isolation pads installed underneath the unit whether
it be on concrete slab or on brackets mounted to
house. Sometimes the new units come with compressor that has a jacket installed over it

Testimonial: "Thanks, I was told that the noise at the TRV valve on the air handler is liguid refrigerant (rattling noise) and that the systems are mismatched."

Hi I am sure this model number is correct and it is a 3 Ton unit.Normally when the breaker trips as soon as you reset it, the compressor is compromised. Happened to me yesterday on a 5 ton heat-pump. When this happens, what you can do if you are a handy type of man, is to prove this. I don't know if the is is a split system or a all in one package unit, doesn't matter. Get to the compressor compartment. Of course the power will be off.If you can see the run capacitor, take a screw driver and short across the terminals to discharge it, as it could have a small amount of juice in it, I doubt it. Anyway, remove the plastic cover to expose the terminals. They can be hard to remove sometimes, just use a screw driver to push the clips in. Wire colors should be black for common, yellow for start, and blue for run. Write down the order they were in. To be safe, tape the metal connectors so they wont touch metal when you turn the power back on. After you have done this, turn everything back on. If the breaker holds and everything else is on, fan and so on, this proves the compressor is probably shorted to ground. If this a/c is rather new, I would replace the compressor. If it is old, I would think about getting prices on a new unit. Just food for thought. Please let me know on the out come of this test, please. When a compressor shorts out, or locks up, it draws what is called locked rotor amps/LRA which could be from 49 on up, and your breaker can be 25, 30, 35 to 40 amps so it will trip. Keep me posted and do this test, it is very easy to do.
Sincerely,
Shastalaker7

BUZZING NOISE FROM MY HEAT PUMP


Take a look at this YouTube page that explains with good videos what are some of the common problems with heat pump noise. The one that seems dominant is the defrost cycle a heat pump goes thru when it melts ice off the evaporative coils. In defrost cycle, The compressor runs but the cooling fan does not, so you will hear a loud buzzing sound and the unit sounds like it is stalled...because only the compressor is running to generate heat to melt coil ice.

How old is the unit? Heat pumps don't work when it's real cold, you know it's limits. If it's not real cold outside, then it may be low on gas or such and need a service call.

Remove the cover of the circuit board and controls on the outside unit. Some units have a thermostat that allows you to set the temperature at which it switches to the second stage of heat. Set that for about 34 degrees.

My Amana asx 16 seer 4 ton system installed 3 years ago quit working. The alert light is flashing 6 times. What does this mean?


Hi if you are looking at the indoor unit and this is where you see this flashing light, remove the panel. The circuit board is where this led light is. You will also have a 3 to 5 amp fuse plugged into the board. Look for a chart on a panel door. It will be glued there. It will tell you what the problem is according to how many times it flashes. Could be several different safety switches. Make sure there is no door panel switch on the indoor unit, has if there is, the unit will not run after you remove the panel, it kills power to it. You may need to tape it down so you can have power to run it and check it out. Is the indoor unit a gas system or is it a 4 ton heat-pump? If you cant find what I have said, get back to me after checking these things and let me know . Check all breakers. Let me know if this is a package unit or a split, indoor and outdoor unit, or all in one. I will wait to hear back from you on this.

Check to see if there's low voltage reaching the contactor's coil. If there is. and it doesn't close (pull in), then it's defective and should be replaced. Cut the power and check ohms to be certain.
