Hello all,
I have a through the wall A/C that is a little over 2 yrs old. Its blowing cool air just not really cold air. The thermostat is at 60. I think the thermostat is stuck, Is this a DIY. I'm pretty handy, but don't want to make it worse.
The unit is a Fredericks wallmaster.
Thanks
Changing the thermostat on my home A/C?
If compressor is running, it's not a thermostat issue. Check condensor coil is free of crap, only thing left is low freon
Changing the thermostat on my home A/C?
If your stat is set at 60 and the unit and compesser are running the stat is not the problem.It sounds to me the freon level is low and needs to be charged.Need to have unit serviced...
Is your building very hot? The heat load may be more than a small A/C unit can handle.
Is the exterior paint on the outside of the building a darker color or is there shade on the solar exposed sides of the building?
Solar radiation including the same UV that burn our skin is causing buildings to generate heat the building isn't designed for. Go to the following link to see what temperature actually looks like and how it can be changing your building. http://www.thermoguy.com/globalwarming-h鈥?/a>
The thermostat is not bad the condenser could be dirty how much heat blowing outside when running. If the unit is low on gas the evap coil will have a warm section to it remove filter and put your hand up and down the coil if it is cold all the way then the gas is ok. window units need cleaning once a year. remove take outside and rinse with a hose well everything, let unit dry out well 24-48 hours before you plug it in.
Measure the temp of the supply air then measure the temp of the return air.Subtract the two measured temps.If it is less than 15 ,you might could have a problem.If it is more than 15,everything is probably o.k. with your system.
Sounds like the t-stat is bad though.
When you replace it,make sure you shut the power off to your indoor unit prior to replacing it or you could smoke the transformer and have to replace that too.
Then restore power after you change it.
Notate everything you need before you buy one like gas,electric,heat pump,programmable,non etc.

How hard is it to change the thermostat on your car?
All of my fluids are topped off, and the defrost works and the a/c works.. but the heat doesn't work. Is that the thermostat?
How hard is it to change the thermostat on your car?
seems to me like you have an in-line valve to your heater core that is closed. look under the hood, find the lines that go to the heater core and see if there is a valve, the cable from inside may have come loose. there also might be a cable to the duct that has come loose under the dash area, good luck
How hard is it to change the thermostat on your car?
Depends what kind of car...generally they are very easy to replace.
It's easy in mine
Could be, but could be a number of other things too. If your car is overheating then it is most likely the thermostat. It's very easy to replace. Takes about 10 minutes depending on where it's located.
depends on the car if its easily acsesable a piece of cake. unless you do like i did once and used the wrong bolt and broke it part way down. then you need a drill and tap(ps where the world did spell check go?)
It is very basic, and yes, even you can do it ! Wait until after the engine has cooled. Toward the front of the engine,right on top,( in most cases) there is a big hose. It goes from the radiator to a metal thing that looks like a small softball. There are 2 bolts that hold it down. Unbolt them and the thermostat is right there for you to pull out and replace. Make sure it goes in right-side-up. Take carefull notice as to how it looks before you remove it. Make sure, also, that the gasket is still complete. Good Luck !
Probably not if the defrosters work. Sounds more like the cable that switches between heat,A/C,etc.Or possibly a vaccuum line is off,(change your radio lately?).
your thermostat allows the engine to maintain it's operating temperature.
If the thermostat is locked open (broken) the engine would have a hard time heating up. Your temperature gauge would stay in the %26quot;blue zone%26quot; and the heater/defroster would blow out cool to warm air.
If the thermostat is locked closed (broken) the engine would overheat. Your termperature gauge would be in the red zone soon after getting on the highway. Your Heater would be producing lots of hot air.
So if both your defrost and heater settings are producing just warm air and your temperature gauge stays in the cold/warm zone, it's probably your thermostat.
If the defrost pours out hot air, but the heater does not (they use the same source for heat, the heater core) then you have a broken or damaged flap in the dash that is not allowing the hot air to go through the heater ducts.
To replace your thermostat, go to your local automotive store and pick up a repair manual. It will walk you thru the steps to replace the thermostat. It is usually located in the top front of the engine, held on with two bolts. You may have to drain your radiator to make this repair. The antifreeze is resuable, so don't throw it away unless it's really cloudy, then recyle it.
your thermostat has nothing to do with heated ventalation it mearly controls the flow of coolent from the radiotor to the block the problem you are stating is a heater core and its most probably blocked or just jacked up so to fix this you will have to take it out and either flush a stream of water or get a new one which might be cheap or most likely cost you an arm and a leg
It's not hard, but the thermostat controls the temperature of the engine not the operation of the heater? Good Luck!!~:)=

How do i change a thermostat on a Oldsmobile Cutless Ciera S 6cyl.?
the intakemantefold is right in the way of the thermostat, and the thermostat housing is sideways, i have very little room to work with and i am not sure how to get the bolts off due to the thight fit. and im not sure if i can even take out the thermostat becouse of the location, becouse i'm pertty sure i can take of the exsoust mantifold.
How do i change a thermostat on a Oldsmobile Cutless Ciera S 6cyl.?
You can try putting the year, make, and model in on the AutoZone website by clicking on the %26quot;Repair Info%26quot; link. It will show an online guide that is just like a Haynes or Chilton repair manual. It is available for most cars. Maybe it will show an easy way to get to the thermostat.
How do i change a thermostat on a Oldsmobile Cutless Ciera S 6cyl.?
There's a great tool called %26quot; gear wrench,%26quot; It's a wrench that can go into tight spaces and function like a ratchet. Check out the link Im enclosing with a picture of it
if you don't know how, don't do it...you may cause more trouble than it's worth...go to a repair shop and let THEM do the work. Save yourself time, trouble and money...software smell like shampoo

How to change the thermostat on a 2000 Chevy Malibu.?
How do you change the thermostat on a 2000 Chevy Malibu? I see the top bolt and can feel the bottom bolt to take off the one peice. (sorry, don't know much bout cars) How do you get to the bottom bolt?
How to change the thermostat on a 2000 Chevy Malibu.?
I have done many of these.The service manual will tell you to remove the exhaust crossover pipe. Please don't do this, you'll just be wasting your time. I always use a 13mm open end wrench and reach under and around the crossover pipe with my right hand with the wrench and my left hand i put in between the exhaust crossover pipe and the thermostat housing(the one piece you are referring to).The left hand helps to position the end of the wrench onto the bolt and holds it on while turning it. It will take a little while to remove the bolt, as there is not much room for the wrench to move, but it works. You also may have to keep flipping the wrench over to get it back on the bolt in the limited space.

go to a parts store and ask them for a book on your year of car. and it will give you step by step instructions on how Better than guessing and braking something change the thermostat
if you remove the top radiator hose it should be easier

I have a 2005 Corolla XRS. I find it a pain sometimes. I think the thermostat is under the alternator. How do I change it?
How do I change the thermostat in my car?
there should be a hose coming from your radiator a big hose. it leads to your manifold. take that hose off and there's your thermostat
How do I change the thermostat in my car?
Heres a plan of attack. BRING TO A DEALER IF YOU DON'T KNOW WHAT YOUR DOING. there did that help?

I want to change my thermostat?
I have a 4 wire thermostat setup in my home and i want to replace it with an electric. I don't want anything fancy just something that will easily replace my old one. The wires are Red, Blue, Green, White.
I want to change my thermostat?
red to red BLUE to yellow green to green white to white old t-stat wire they used blue for yellow by the way if your changing it because it isnt working right its your system not your t-stat
I want to change my thermostat?
You can purchase a new thermostat controller from your local hardware store. It has directions on how to hook up the wires for your system. I have replaced mine at least two times in the past 20 years.
Good luck
Go buy the kind of themostat you want and it will be marked as to where the color of wires go to install it. The thermostat will be marked and/or the instructions will tell you. Easy job..........UJN

Engine compression and thermostat question?
My 98 Camry with 125,130 miles had a compression reading as follows: What do they mean? Should I keep the car? The specs is 178psi or more and the difference of 14psi or less per cylinder.
Cylinder: Dry Wet
1 220 220
2 220 220
3 215 220
4 210 215
I recently change the timing belt, accessories belts, and water pump without changing the thermostat. Would the thermostat create problems in the future? Thanks very much for your help.
Engine compression and thermostat question?
These numbers are very good. At this mileage, it would be good preventative maintenance to replace the coolant, the temperature sensor, and the radiator fan switch. Use only genuine Toyota parts and coolant. Do not use the typical %26quot;green%26quot; coolant, it will cause premature pump, gasket, and radiator failure. Also, if this were my car, I would do a de-sludging of the engine, and use only a good synthetic, like Mobil One. Good Luck!!!
Engine compression and thermostat question?
Babyface:
These are good readings. You state that 178 +/- 14 psi is the spec. The measured values are well above minimum and within the stated tolerance. Uniformity between cylinders is very important, which this engine shows.
With 125K miles, it shows good maintenance.
The meaning of these numbers is simply that the condition of the valves, pistons/rings and cylinder walls is (very) good. A special gauge can measure the 'pressure' produced in the 'compression stroke' of the engine.
You will know if the thermostat goes bad because the engine may not get up to temperature, or overheat, depending if it fails open or closed.
These are not expensive and easy to replace on a 4 cylinder camry. When you get some extra money, have it changed as a maintenance item.

Those compression readings are pretty even. if the spec says 178 (or whatever) the guy testing it probably did not open the throttle plate to allow more air into it. It sounds like you did NOT have it tested at the Toyota dealer!
For a 10 year old car, the compression readings are very close together so I would not worry about it.. A careful valve adjustment might get them even closer.
Dont worry about the thermostat, its an easy fix, and they dont go bad all that often.
Toyota engines last a very long time, 125,000 miles is NOT BAD!!
150 psi and up is excellent its a Toyota and thermostats are cheep your good to go.
I would say keep the car. The reading you have are dam good.Your oil lose past the rings is minimal.And with a new O2 censer and a new catalytic converter, should pas any I.M. test.
compression is good keep the car but do change the thermostat after and during a water pump change not cause the other is bad just for safety reasons it might just not be the right size for the pump and its like changing the front door on a old house you would want to change the locks just cause there old you get my drift
theese are normal readings, actually better than normal. dry readings is the psi in the cylinder normally as it is. wet reading is with a squirt of oil. this is done to see if the piston rings are good. ur engine is fine will last u 300K or more without a problem as long as u take care of it. wouldnt worry about the thermostat those are replace as needed. yes keep the car as long as the rest of its ok. the engine is fine.
