Would need more info, which door are you talking about? Blower door with power switch? At what point in the firing sequence does the unit fail? So the burners ignite?

SOURCE: Inside Electric Furnace/Air Handler Not Working. Please help!

ok this can be simple or tricky is the breaker that trips the same size as the one in the breaker panel 2.look in the unit itsself see if there r breakers inside the unit there usually are and they might have tripped it might be as simple as flipping a breaker but the problem with the breaker tripping is what concerns me now it may just be undersized or getting weak and finally crapped out get ur meter and flip the breaker on and see if u r getting power to the unit if ur not u have gott a breaker that isnt letting power go thru now if u have power u might have a bad blower motor turn the unit on and calling for the fan on if the fan doesnt start try spinning the blower by hand now if it starts then u probably have a bad capacitor they r usually mounted on the side of the blower housing it is oval and its gonna be a 5mfd(microfarad) or 7.5mfd and that couldve been what was kicking the breaker now if the blower is stuck and it wont turn or its very hard to turn then make sure the blower wheel hasnt slipped on the shaft and is rubbing up against the housing if it is just loosen the set screw and set it back even and tighten it back up now if the wheel is free and its still hard to turn then u have a bad blower motor its not a big deal to change out and not real expensive if this dont help hit me back and well walk thru it hope this gets lil momma and the pets warm have a good day

SOURCE: what should the pressure readings be for a

Hi, this depends on the outdoor air temperature and type of freon this unit has. The hotter it is outdoors, the higher the pressure will be as they use a pressure/temperature relationship. If the unit is R-22 and lets say it is 90* F. out side, the low side or suction side will be at around 68 to 72 p.s.i which would give you an evaporator temperature of 40* F. Head pressure would be at around 90* plus 27*= 245p.s.i. This is if the condenser fan is in good condition and the outdoor coil is clean. If you are using a set of manifold gauges you have the pressure/temperature scale right on it. If the unit has a TXV for metering, you would need to charge it using the subcooling method. On a Non-TXV you would use the superheat method. If you are using the new R-410a freon, the pressure are extremely high in these systems compared to the R-22 system, so make sure you look at the units data plate to read the type of freon. The color of the container is green for R-22 and a Pink for R-410a and the 410 a unit will display a pink warning sticker on the unit to tell you. The pressures on the R-410 would be at 90* F, low or suction side at that temp is around 125 p.s.i., and around 400 to 420 p.s.i. on the high side, much higher then the R-22. You would also need a manifold gauge set made just for the R-410a (AZ-20) as of the extreme pressures in the system. There is never a set pressure to go by as the outdoor temperature will raise and lower the pressure of freon very fast. If you are asking this question because you have a manifold set and are taking a reading, the unit has a charging method pasted right on it from the factory showing what pressure they want it to run at. Your gauges also can be used as a pressure temperature chart, or you can pick one up free of cost at a a/c parts house to keep with you. It will show you how to calculate the charge for your unit. If you are familar with pressures, this should be of a great help to you. I hope that I have helped you on getting the unit charged properly. Please keep me in mind when rating me, as I know you will be kind. Just drop by a wholesale a/c parts house, walk in and ask for a pressure temperature chart, and they will hand you a couple of them. They have very good information and no how on all of the most common freons in use today.
Best of luck

SOURCE: Will not light pilot light. Why?

did you bleed the gas line?
you must loosen the connection at the water heater until you smell gas coming out, then tighten. wait at least 5 minutes before attempting to light. this will give time for the gas to dissipate
if it still wont light... are the connections to the thermocouple tight? if that is tight, might be a bad thermocouple, you will need to replace it.

Why is there a flashing red light on my american freedom 80 air conditioner/heating unit?

There is a flashing red light on the control board to let you know the board is powered up. It is also used to diagnose errors with the system by counting the number of blinks in between pauses. there should be a legend on the board or in your instructions for the unit.

How do i read american standard freedom 90 error codes

can you look thru the small circle window of the cover of the furnace panel? to see the red light on the furnace control board. If you can see it. Count the blinks of the light. Also keep track if they are long flashes or short quick flashes. they might be 2 long flashes and 1 short or 5 short and 2 quick. After you determine the flashes or the sequence of the flashes. take the cover off the unit and look on the inside panel of the blower door. it should give you the code sequence of the problem you are having on the legend of the wiring diagram. or if there is no legend or wiring diagram on the inside panel of the blower door. it will be in the paper work or unit information package paperwork that came with the unit. If you don't have that. You would need to get the model number of the furnace from inside the furnace. the model number is usually inside the blower door or it could be close to the burners of the furnace itself. if you don't have the wiring diagram or the paper work. then you will need the model number for sure. I think you can go to American and look thru their online library of unit specs to get that info. to look thru their library you have to have the exact model number or I believe at least the first few numbers of it. Not sure how many of the first few you need to have. if you cant find the info and have the model number. Give it to me & I will find it for you. Or see if I can find it? I think is were it is. Or at the American Standard home AC & Furnaces home page you can search for it. It shouldn't be too hard to find. Or another way would be to call a American Standard parts or unit vendor and tell them your name is Dave or some other common name. And that you work for sears or some other large company like that or a large company in your area. And that you need tech support to get you the code info for that specific unit. If you call when they are busy they usually wont verify the company info or that you do work their. just hearing the company name, they will think you work for that place and get you the info. At most wholesalers they are just trying to make sure they aren't talking to a home owner or a regular person. when they hear a company name they will give you the info you need or tell you were to get it. Also its a good idea to be prepared when you give a company name that you work for or that you don't really work for. the guy on the phone will ask for the name of the company you work for. My name is Dave & I work for sears service. the one on Broadway Road (give them the address and or phone number) of the place. Some places use the phone number of the service place to look up their account and they will have a list of names and want you the verify the address or the phone number. Works good for getting info about a unit that you cant find any info anywhere else. But trying to get parts that way doesn't usually work unless you know how to do it. I would say but not sure these guys on fixya would be okay with that. Hope they don't have a problem with me saying how to get info from a vendor about a trouble code or where info for a code can be found. if they don't like it I am sure I will find out soon enough. and hopefully they will give me another try at this before taking any actions on me or on me being on here.

hope I was of some help to you. if you haven't already figured it out or if no one else has tried to answer your question.

Is the American Standard G50T 2-3-6 a good water heater? I have trying to find stuff about them on Google but I keep getting results for american water heaters not american Standard and the reviews are not...

Generally, they are a your normal low end hot water heater. I have seen American Standard units last up to 20 years (like mine) with not problems, and I have seen them not last three years before the tank ruptured.

We have more calls on the Rheem and Brandford Whites than American Standards as far an minor problems.

Pros: Cheap; reasonably reliable; parts readily available.
Cons: Not energy efficient; tank quality - flexible.

When mine goes would I replace it with another American Standard? No, I would install the Bosch tankless water heater.

Most furnaces have a tech manual inside. Under the blower cover should be a trouble shooting guide. Call the dude and tell him what the problem is. You have no other source of heat and you live in alaska?. If I was you I would invest in a comfort glow gas vent free heater for emergency. No power is needed to operate the heater.

American Standard Freedom 80 - 9 blinks - Ignition issue

I will try to help. Your furnace has to have a good ground before the igniter will work. The draft fan starts purges for a few seconds and the ignitor is supposed to come on. If not check to see if the contacts on the air switch on draft motor are closing. If you ahve changed the ignitor that is not your problem. Another possible problem is the baord that feeds the ignitor. But check the air switch first Rus. Keep in touch.

No heat!, light blinks 3 times

Make sure the inducer motor is free of condensation and that all water is able to drain out. Unfortunately your furnace is a lower-grade “builders” model and does not have the same quality of components and workmanship as a Carrier or American Standard furnace. Prior to these failures, It was about 1/2 the price of the units mentioned. And the warranty drops off quickly. You get what you pay for.

Contact Goodman to see if they will cover the cost of your parts at 1-877-254-4729 US only. Their own motto is “Quality Makes the Difference”. It sure does.
