(HVAC) Furnace Not Igniting Quickly

Carrier // Day & Night // Model 397HAW036060 (1982)
Furnace doesn't seem to be Igniting Correctly.
Blower comes on and runs for about 10 minutes, Furnace starts ignition process, it ignites-then ''Blows-Out'', repeats this same process 6-9 times before Ignition is Constant, meanwhile Blower is Blowing Cold Air. Isn't this condition wasting Gas? How can I Fix?
3 Years ago the Electronic Control Board was Replaced, 2 Years ago the Control Valve & Blower Motor were Replaced. Checked the Igniter and it ''appears'' to be working Correctly During Cycles.

    No Back Draft. So, which Part would need replaced, and How to do that?

    I keep coming up with "other" responses, that the Burner is supposed to Start BEFORE the Blower comes on, is that Correct? and How to Fix that?
    At present the Blower comes on 1st (Hi-Speed), and runs 10-12 minutes BEFORE the Burner starts Cycling, Guess I'm getting confused...

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.

    I used your model number as a Google search key. I got a hit on your service manual pdf. It describes how to removed and clean the burners and pilot assembly. The flame sensor is described as a switch but its not more specific than that. Clean the pilot assembly and the burner orifices paying particular attention to the orifice hold that are close to the pilot as this area may accumulate extra deposits. If that does not fix the problem then replace the pilot assembly which includes the sensor. The Service Manual is very specific about how to remove the burner and pilot including pictures but if you need more help than that write back.

    You have two "blowers" in the unit. One is to move are over the heat exchanger (room air, big one) and the other is to move air through the burner chamber, then through the exchanger to extract heat, then to the exhaust flue (the draft blower, small one). The furnace must establish good draft before ignition or bad things will happen. There is a draft sensor (switch attached to a plate in the draft system that senses good air flow) to prevent this. If the draft fails or is weak after the burner is on then the draft sensor opens and cuts off the natural gas (or propane). The burned flue gases coming off the burner do not get mixed with the air in the rooms of the house. A heat exchanger keeps the hot burner gases and the room air separated from each other. If there is a hole in the heat exchanger you can get carbon monoxide poisoning in the room therefore the heat exchanger has to be clean and sealed tight. You may have a problem there if the draft fan or flue is full of dirt or otherwise obstructed and does not give the flue system good steady air flow. That can shut off your lit burner early.

    If the room air blower starts up on a cold furnace the rooms will get a cold air draft because the heat exchanger in the furnace is still cold. Therefore the furnace is designed to heat the exchanger first with the burner gases and them start the room air blower up on a delay or at a set exchanger temperature (your case I think). That way hot air comes out in the room air ducts almost immediately. Your draft blower starts before ignition. The room air blower starts later.

    There was a bad typo in my last posting. I typed "orifice hold." That should read "orifice holes"

I have a carrier Day & Night a/c - heater unit. the model # 591ANX0480000ACAA, 208/230 volts. my blower fan stays on continuously, even after turning the thermostat off. the condenser fan does not come on...

If the blower fan in the furnace won't turn off, there is a tripped/blown limit. It's a safety. As for your condenser fan it could be a run cap or motor. Do yourself a favor and have a licensed HVAC contractor take a look. Find a NATE certified or ACCA member. You will find a much better more qualified contractor.

Sounds like the fan limit was not replaced correctly. You can try switching the blower to the On position (instead of Auto), if the furnace runs properly with the blower on that would be the most likely culprit.

Hi smargyle,

Welcome to fixya!

I can provide you with diagrams for the old Carrier therm and for the new Filtrete therm. But, I would need to know what the model numbers are for each therm plus how many speeds AC you have.

Please reply back with that information and we will get your AC back in working order.

the electrician might be able to help somewhat but an hvac tech is the person to call. It sounds like you have multiple issues if the thermostat is acting up that bad replace it!! but that wont stop the noise from the furnace thats either the blower wheel or the motor. ive seen filters get sucked in the blower wheels and destroy them then they make a buch of noise. if the filter hadn't been changed in a few years then the motor is probably going bad. you could check to make sure there is nothing in the blower wheel. make sure the power is off open the bottom compartment of the furnace use a flashlight and look around then stick your hand in there and feel around, if there were animals before sometimes a blanket of hair can develop on the blower wheel. make sure you dont touch the capacitor which looks like a little siver can near the blower motor it can shock you even with the power off. good luck

Gas valve lockout

It means that the furnace isn't igniting and for safety the control board is preventing the gas valve from opening. Turn off the power to the furnace for a few seconds then observe what the furnace does in heat mode. Some furnaces will run the blower for a minute after you power it back up. After that see if the furnace tries to come on. If you are still getting the code then one of you high temp limit or roll out switches has tripped. Now is the time for a service tech. Make sure that you check you filter and air flow too. Low air flow means the furnace may be over heating.
The other thing is the hot surface igniter. Look closely at it with the power off. Do you see a white spot on the element or a crack. If so the HSI is bad. It's an easy replacement but DO NOT touch the carbon element with your fingers and be very careful handling it as it is EXTREMELY fragile.

Furnace won't come on after being off several hours, new relay

Lets test the t-stat. Take the cover off the stat locate the terminals R & W take a small piece of wire and holding the wire jump across the two R & W terminals. Does the furnace start up immediately? or does the same problem exist? Sometimes in diagnostics you have to start to eliminate the problems one by one. ken
