Make sure you give it time. Gas furnaces ignite first and then the fan comes on. It will run for a while to heat the exchanger first. If the fan comes on with the heat it will blow cold initially. The fan also continues to run after the burners shut off to expel the existing heat in the ductwork

SOURCE: Ruud Furnace won't turn on

Take of the access panel on the furnace and look for a wiring diagram either on the back of the panel or inside the housing. There will be a diagnostic chart on it that will give you a hint what 2 flashes mean. I think it is a "no Ignition" code. If it is, with the access panel off and the door switch taped in the closed position, the furnace will try to start if the thermostat is calling. You want to look at the control module to see if it is flashing, then you should notice a small fan that pushes out the combustion products start to turn. Then if you look in a small view port, you should see an orange glow followed by a clicking noise at the gas valve. Then you should notice a blue flame in the view port. This flame must stay on for 5-6 seconds or the unit will turn it self off. If one of these do not happen, you will need a technician to troubleshoot it. Check to see if all wires and hoses are tight and in place. Make sure your condensate hoses are not blocked and free of water. Make sure there is no blockage in your vent pipe(s).

SOURCE: Amana Air Command 80, 20

Hello Bob,
Welcome to fixya,

You said, Amana Air Command 80, 20 years old.
Electronic ignition.
Furnace does not start.
Good power to furnace.
Thermostat properly set.
Where do I start looking?

Sounds like you possibly have one or more bad jets if the unit is a gas furnace!
Let me know how it goes.
Huuum

WOW, listen to this story!
I understand you are looking for the solution to fix your furnace your self.
But I want to tell you my story about my smart wife and our furnace.
When we moved into this house the furnace was 20 years old and she suggested that we put a new one that it will save us money.
I laughed at her and replied if it's not broken why fix it!
Six years later it finally broke down and I replaced the whole furnace and central air unit with a new one.
Our utility bill went down $100 dollars a month!
That's $7200. that I lost over 6 years due to not respecting my wife's power of reasoning!
If you can afford it or can get financing replace any unit 20 years old and it will pay for it self.
Can you imaging $1200. a year for 20 years is $24,000 dollars I'm saving with a new and efficient unit.
Do the math!!!!!!!!!

Thank You,
Huuum, Hope I gave you some good fatherly advice.
Please remember to leave a rating

does the furnace ignite?? your system may not have been lighting and has gone into ignition lockout count the codes of the led lights then remove panel led diagnostic codes are listed there.
if led codes indicate no problem verify capacitor is good and that mtr is getting 115 volts.

Buy a new ignitor here; The Ignitor Store. Or talk an Amana dealer/Contractor to sell you one. They can range from 15 to 35 bucks! Depending on their mark-up. Give them your model number, and or ignitor part number. Their simple to change out, good luck, please contact if you have any questions.

SOURCE: (HVAC) Furnace Not Igniting Quickly

Make sure a back draft in the flue is not happening. Wind can blow it out until the flue heats up. The flame sensor may not be close enough to the burner flame. It may be weak and need to be replaced or if its an optical one it may be dirty and not see the flame very well. Its not wasting much gas but it puts extra wear and tear on the gas controls, is noisy, and, as you said, blows cold drafty air. A gas control system that has issues of any kind is not real safe. It needs to get fixed.

Lighting pilot on Ruud 80 plus furnace?


Hi, There is no pilot and the flame is lit by a hot surface ignitor... The hot surface ignitors go bad frequently...you probably need to replace that...

Here is a tip that will help you try to figure out why your furnace is notworking.

I have a ruud deluxe 80 plus furnace, the blower keeps running and it wont shut off. i have turned the thermostat off and its still running, what could be wrong?


Hi,
That could be a couple of things....
Open up the bottom cover and take the wire off of the "G" terminal that goes to the t-stat...then replace the cover and see if the blower still runs...
If it runs then the problem is intenal to the furnace, probably the integrated control board or a high limit is tripped...
If that stops the blower from running then you have a bad relay in the t-stat ora shorted wire going to the t-stat.

Ruud achiever 90 plus furnace will not start with door on.


I would try to check your return air first, making sure there is no blockage and that your air filters are clean. It almost sounds like when you take the cover off, you are pulling enough air into the system for it to run, but as soon as you close it off, it's not getting enough air flow, therefore, tripping a limit switch inside the furnace. Most furnaces will also have the codes for the flashing lights and what they mean on the inside of the door covers.
