Question about Amana Gas Furnace 90 AFUE 115,000 BTU Variable Speed

1 Answer

I have an Amana gas fired furnace which does not heat. It is a "90% Single-Stage" unit. I can see that the pilot light goes for a few seconds but nothing lights. It was new about 7 years ago

The thermostat is working as I can get the blower to go on and off depending on the temp I set. I can also see the pilot light go on for a few moments after the blower starts but nothing else happens

SOURCE: heat pump outside unit not running

It sounds like your defrost board failed. You will need a tech to replace it. With that model it may have a parts warranty but you pay labor(?)

SOURCE: Amana PGD60C1152E no heat

Your thermostat Function 0170 must be set to "1" for Single Stage Heat/Cool. Function 0180 must be set for "0" for Heating Fan Control. Function 0240 must be set for "5" for the Heating Cycle Rate for your <90% Gas Furnace. If you have already done these steps or if, after doing these steps, you continue to experience a problem, you problem could be with your Gas Furnace. I'm including some links for information on your system and thermostat that include wiring diagrams.

Amana 80sse furnace fire up work for about 10 min. It goes in lockout and inducer motor stay on


Robert, that is a typical indication of the furnace cycling on its high temperature switch. Look for a dirty filter, return air blockage or any other thing that would cause air flow restriction across the heat exchanger. If nothing else is evident, possibly attempt changing the heating speed to medium low or medium high for heat to improve air flow. But if it worked with no changes prior to this problem, it has to be lack of air flow that is causing the issue.

Tip

2 Stage Furnaces More Comfort and Save Money


Two stage hot air furnaces can save you money and make your high efficiency furnace even better. With your furnace running at low fire instead of cranking up to the highest heating output in mild weather you can be more comfortable while saving money.

Many people think that they are getting the best they can get by buying a high efficiency single stage furnace. What they often don’t realize is that they could do better yet and for a few dollars more have a high efficiency 2 stage furnace that could keep them much more comfortable.


There are 2 stage hot air furnaces that are now available that will only run at half fire if the full fire is not needed. With a two stage furnace in mild weather when only a little bit of heat is needed, the furnace will have longer run times on low fire. This will keep you room temperatures from getting too hot before the thermostat reacts and shuts the furnace off again. This will help to keep your temperatures from overshooting the set point and help to keep your home much more comfortable.

Many of these two stage furnaces also have variable speed blowers that run at a lower speed when heating on low fire. This will also help to save money on your electric bill, because these blowers use very little electric when running at these low speeds. Air noise from the blower running at a high speed is also reduced.

If you are thinking of replacing or installing a hot air furnace, make sure that you ask your contractor to give you a price on installing a two stage furnace. The price difference probably will not be much higher than a high efficiency single stage furnace. However the comfort of the two stage furnace coupled with the electric savings will make the extra money well worth it.

If the pilot go out on a furnace would gas continue to flow to the pilot , or would it shut off with in a few seconds


The pilot flame heats a thermocouple, so if the pilot goes out, the thermocouple cools and shuts off the gas. It can take anywhere from 20 seconds to 2 minutes for it to shut off. You should hear an audible click when it happens.

Is there an on-off switch on the furnace?


Generally, if there is not a breaker within line of sight, there will be a toggle single pole switch that will shut the furnace off. The blower cabinet will also have a door switch.

I am trying to install a thermostat and I am not sure where to put all the wires... it is for american standard freedom 90 two stage - furnace and air conditioning


Should be like this:

Y from furnace goes to Y on thermostat (yellow)
C from furnace goes to C on thermostat (usually blue)
G from furnace goes to G on thermostat (green)
W1 (first stage heat) to w1 on thermostat(white)
w2 (second stage heat) to w2 on thermostat (black)

Doesn't sound like you have a heat pump but if you do "o" will also have to be connected which is the reversing valve.

Hello, The problem is the ignitor comes on for a few seconds then goes out. The fan keeps running but no heat is coming out. Any suggestions? The model we have is Amana air command 90. Thanks.


If your furnace lights and the gas stays on for 8 to 10 seconds, then shuts right back off, then you need to clean your flame sensor with light sand paper or steel wool. You might need a new flame sensor, but most of the time they can be cleaned an will work well after cleaning.

Gordon-Ray overhead radiant heater that won't go into high fire


Is this a standing pilot unit. So when it goes into high
fire is it just actually going from pilot to burner on ?
If this is the case and the burner shuts down, then
it is the flame sensor.

If it is two stage heat and 1st stage is fine, then when
second stage comes on and goes out, I would be looking at the supply of gas.

Thermastat and furnace


you should have 24 volts between yellow and white wires at the stat when the stat is set to heat and set as hot as it will go. burners should light first then 3 to 5 minutes later the fan motor should fire up. if burner doesn't light check the wires going into the top of the gas valve see if you have 24 volts arriving there from the stat. if you do then the gasvalve is probably bad. you can bypass the action of the stat by jumping red to white on 90 percent of the stats made and in a few seconds the gas valve should click open gas flow to main burner where pilot ignites it. another easy check you can do is flip stat fan switch to on. fan should come on at once. if not then you have either no high voltage to unit or no low voltage ( as in a bad transformer). if the fan comes on you know you have high volts and low volts...by cover i assume you mean the decorative cover but there second cover with the mercury bulbs and all is still there. if you have only the bare subbase then new stat time. sounds like an old furnace if it has a standing pilot, it should be checked for cracked heat exchanger by a pro with a n electronic carbon monoxide detector. NOT a diy item due to the real danger of co poisoning.
