Furnace stopped lighting and blowing but is still making the " before ignition" sound

It was running fine , then I realized it seemed to be stuck on the " starting the cycle mode" where it sounds like it is running but never kicks in to lighting then blowing hot air. The furnace/AC unit is 3 years old. I turned the thermostat down below the current air temp and the unit clicked like it was going to shut itself off but it is still making the same noise. I shut the unit off at the thermostat , no change ..I shut it off T the breaker and it is still making the same noise. When I opened the unit door the green light was flashing 3 quick flashes then off then 3 quick flashes. It I s 4 am and too early to call my furnace man unless it is an emergency

My lennox furnace works just fine except that 25% of the time the fan keeps running when it shouldn't and blows cold air


You are using too restrictive of an air filter. If the codes you are getting off the lights says anything about a high limit this is the cause of your blower running all the time. Use a less restrictive filter or have your contractor install a media filter in the system. if you reset the furnace and it does not stop running the blower you have a stuck limit switch and may have to get another or call a service tech to reset it or replace.

The Goodman Heater was installed in 2004. Thermostat set at 75F, the fan that blows CO2 out was on for about 1 minute, then I could hear the sound of the gas blowing into the furnace, but the ignitor...


Problem: Your furnace will not ignite the gas to produce heat for your home. When a furnace has a bad ignitor what I see most of the time is the following sequence of operation:


1. Thermostat calls for heat. 2. Draft inducer motor starts. 3. Pressure switch attached by a small plastic or rubber tube senses the negative pressure produced by the draft inducer and closes. 4. Draft inducer runs for 30 seconds to a minute before you hear a gas hissing sound. The ignitor did not glow, the flame sensor (a small metal probe about 1/8" in diameter, with a white porcelain base) does not sense the flame, so after 8 to 10 seconds the hissing sounds stops with no ignition of gas to heat your home. Your furnace shuts down and goes into a lock out condition until you turn your power switch back off and on again. Then the sequence starts all over again with no ignition of the gas. Solution:You probably need to purchase and install a new ignitor. I would suggest that you inspect your ignitor closely for cracks. Make sure you do not touch the ignitor with your bare hands. If you do not visually see a crack, then you could have a furnace control board problem or a limit, rollout switch problem. The furnace's control board might not be supplying the voltage to the ignitor. 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.

Even though this furnace is newer, I highly suggest a licensed tech make sure that this problem is not due to a breach in the heat exchanger causing the flames to go out when the fan comes on. That said, first check that the filter is clean and then check the flame sensor rod. If there is "chalky" build up on the end remove it with sand paper. If this cures the problem then purchase a new flame sensor for a more permanent repair.

Pilot light and furnace seems to work fine but during the night the pilot goes out. What can I do to fix this? Is it the thermostat, thermocoupler, gas line? Dave


My experience with this is that first replace the thermocouple. As thermocouples age they sometimes become less efficient and intermitent. If you still have the problem check that the groves cut in the burner tubes are not plugged because sometimes an uneven flame will blow the pilot out upon ignition. Also any drafts around the furnace can blow out the pilot. Make certain that all flame shields are installed correctly. I have even had pilots blow out when a door was opened causing an excessive draft. And make sure your draft is operating properly and not restricted.

Coleman mobile home furnace...Model number DGAA077BDTB...The furnace about a month ago started going out ( flash code- Combustion Air switch stuck closed)We replaced the thermostat on the wall and it...


I had the same errror code on my coleman furnace (3 flashes combustion air switch failed to close) but at first didnt realize there was even a light that gave codes..Anyways long story short, after searching many forums one guy mentioned about the furnace giving a false reading and talked about improper air flow ( coming in and going out) which isnt triggering the switch correctly. After thinking about it and after getting the furnace to run correctly every time I took the door off to tap on the switch (and other spots not knowing what the problem was yet) I always put the door right back on then the furnace would do the same thing (stop running). so I pulled the door off again got the furnace to work properly and left the door off and tested it. It ran great, it started and stopped like normal for a hour and realized I might not be getting proper air flow. Then I remembered I asked my roommate to change my filters for me while I was gone (which he did) and looked at them while I still had the door off and realized the filters were in backwards! which resticted the air flow so much the switch wouldnt operate fully. so check your air filters, something so stupid almost cost me a house visit by the furnace guy....this may not be everyones problem but maybe I will help someone save a house visit....I still cant believe that was my problem and the furnace is still running great.
