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: Fridgedaire drying- It's screeching!

There are several things that will make a dryer noisy. Here's a list of a few items that I know of. Some may or may not apply to your dryer: FIRST OF ALL, BEFORE SERVICING THE INSIDE OF ANY DRYER UNPLUG THE UNIT OR TURN THE CIRCUIT BREAKER OFF. 1. Drum rollers worn out. Most dryers have some sort of drum roller that supports the dryer drum. There are two mounted under the drum in the rear of the dryer. Some models will have an additional set of drum rollers under the front of the drum as well. You may also here the drum thumping too. Lubricating them with a good quality turbine oil at the point of the spin shaft will get rid of any squeaks or squeals. DO NOT oil the roller wheel as it will slip on the drum. 2. Dryer drum seal. This is a felt gasket or seal that is glued to the rear ring of the drum. When they get old they become brittle and pieces start to break off leaving bare metal scraping against bare metal. They also can become folded and part of it will be seen poking through the back of the drum inside. This seal should ride evenly around the outside perimeter of the drum and should not be seen inside the drum. 3. Dryer drum support glides. Some dryer models have teflon plastic support glides mounting around the ring of the front of the tub, or will have teflon supports mounted under the front of the drum. In either case, if the plastic gets too worn down, the dryer will start to make a scraping noise. 4. Idler pulley. This is a little pulley that provides tension on the dryer drive belt. It is located near the drive motor and can start to make noise. Usually a little bit of lubrication at the point of the spin shaft will get rid of the problem. 5. Dryer drive motor. Sometimes when the drive motor gets a nice collection of dust build up around it, the motor will make noise as the impeller rubs against dust or any other debris caught. A stiff cleaning brush and a vacuum cleaner will help get rid of dust accumulation around the motor. Now, there is a possibility that the bearings in the motor could be going bad too. You would need to remove the drive belt and check to make sure the motor free spins with no power applied. Give the motor shaft a spin. It should glide free with no noise. 6. Dryer drive belt. When the belt gets old it will develop a "glaze" on it and start to slip around the drum. This can causing a squealing noise, especially under heavier loads. This is usually a prelude to the belt breaking. Start with the easy and simple options first. Try lubricating any drum rollers or pulley rollers. DO NOT get oil on the drive belt. Lubricate the rollers at the point of the spin shaft only. Inspect the front and rear of the drum. The seal will be in the rear. Make sure that it is intact and good condition, and make sure it has not folded inside the drum. Also, check for glide supports around the front of the drum and make sure there are not areas that are worn down. Another thing that COULD cause noise, but may not be associated to the problem you are having, are foreign objects getting lodged between the dryer drum and casing. Screws, paper clips, nails, etc., have been known to get caught in these areas and will make some awful noise. If you try everything and the unit still makes noise the drive motor bearings could be going bad. This is usually not likely and the motor can be very expensive to replace. Last of all, some heat on the top and rear of the dryer are normal. However, if it is excessive (you can't place your hand on it and hold it there), you probably need to give the inside casing a good cleaning. This could be a sign that your dryer ducting has become clogged and the unit is actually overheating trying to fight for air. Ask yourself, "Are my clothes taking a longer time to dry?" If the answer is "yes" then you need to clean the unit out and check the entire length of the ducting to ensure it is blowing air out of the vent. Remember also, the shorter and straighter the ducting run, the better. Any sharp bends or kinks (behind the dryer) will cause lint to back up. I hope you find this advice helpful. Good luck and let me know if I can help further.

SOURCE: Screeching noise when I turn on my air conditioner or heater

It may just need to be adjusted (it sounds like it's too loose). If the belt isn't cracked or frayed, you should just have it tightened up a bit . If there are signs it is worn (cracked frayed) replace it.

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.
