Screeching noise from air conditioner

We bought a house where the old owners had an amana in the wall air conditioner (model number 12c2my) which recently started making a screeching noise. It screeches sometimes as soon as you turn it on, and sometimes after it's been on for a little while. We tried taking off the cover, but can't see much (belts, the motor) behind the metal slatted inside (I know nothing about these things!) so we couldn't see the belts and since it's in the wall, and on the second floor, it would be hard to take out to check the back. We were just looking everywhere online to see if anyone had any thoughts before we had to buy a new one (the wall ones seems to cost too much!) Does anyone have any thoughts? Thank you!!!!!!!

SOURCE: Weather King Air conditioner

The inside part is the bit that gets cold, which is where the condensation forms (if using it to cool). there should be a drain. Unfortunately Weather King do not appear to support their products online except to dealers. If you can open the unit up enough to where you can see the space below the coils on the inside part (usually just behind where the air comes out, but not always), you should be able to see the drain - if you can then follow where it goes, then let us know what you have if you can't figure out how to unblock it. If you can post back a couple of photos of the unit and installation I might have a better idea of what to tell you to check. Unplug anything from the power before you start opening things up. If you need help finding your local dealer, please ask and I will look. Hope this helps :)

SOURCE: Fan motor has loud screech.

Check for oil ports on motor. Usually red or yelloe plug in caps. No more than 20 drops of oil. I usually use sewing machine oil.

SOURCE: Loud screeching noise coming from the unit.

A screeching or squealing noise usually comes from the fan motor. There may be an oil port and you can buy a small telescoping oil bottle at a super hardware store or an a/c supply house. Before putting in he oil, remember to TURN OFF THE POWER TO THE UNIT and only use a light squeeze on the bottle - over oiling will cause a mess inside the motor. It may be a sealed motor and no oil ports. In either case, budget for a new motor as if it's to the squealing stage, the bearings are already damaged and it's a just matter of time before before the motor bearings fail. If possible, get oil on the bearings ASAP - and use the proper lightweight oil for made for this application.

My Amana heat pump model PTH153B50AJ does not cool properly. The compressor comes on and the fan works.

This sounds like a freon problem your system probably has a leak in the system somewhere. Amana has tons of problems with there equipment. They make there coils paper thin and they split especially on a heatpump. Amana used to be a good brand and then got bought out by goodman manufacturing and have turned there product into ****. How old is this unit?

I bought a display model and it did not come with a manual. How can I get a manual?

It should be as simple as posting the brand and model number to the internet or even at the amana website. A PDF manual should be available.

We have an amana ac and no manual. The model number is not visible and we can't get the ac to go below 75 degrees. What do we do and how can we obtain the elusive manual?

Here is a link to contact Amana.I could not find a free download for a manual,however I am sure you will need to find out the model number somehow.The model number should be on it somewhere.If it is a unit where you have to mount the casing and then slide the unit into the casing,it should be on the back somewhere once you pull it out.That's all I have for now.If that does not work,Amana should be able to tell you where it is with some description of your unit.Good luck!

House wont cool ..tried to reset breaker in fuse box and breaker outside...this unit is only just over a yr old . the fan thing outdoors is not kicking on..

Does this unit have 2 breakers to it? The model you put down is a PTAC and generally just plugs in to the wall so it would have only 1 breaker. If I recall correctly it's got a 5 year warranty on parts so it may be worth it to check with your local HVAC tech and have them do a diagnostic for you. A good place to start would be Amana who can tell you the authorized service company in your area. They'll get the part for free and should roll the diag fee into the repair cost so you'll only pay for labor (if it even needs a part). Their sales and service number is: 1-800-647-2982. Here's a link to your warranty info:

Get a screeching sound from unit when heater is on.

Chances are it is the outdoor fan motor. Does it squal when you run the A/C? If not it could be the reversing valve solonoid.
