• Integrated control module
diagnostic LED is
flashing ONE (1) flash.
• Furnace lockout due
to an excessive
number of ignition
“retries” (3 total)1.

• Loss of flame after establishment.
Cause may be
interrupted gas supply, lazy

pressure or restriction in flue
and/or combustion air
piping), front cover pressure
switch opening, or improper
induced draft blower
performance.
• Locate and correct gas
interruption.
• Check front cover
pressure switch
operation (hose, wiring,
contact operation).
Correct if necessary.
• Replace or realign
igniter.
• Check flame sense
signal. Sand sensor if
coated and/or oxidized.
• Check flue piping for
blockage, proper
length, elbows, and
termination.
• Verify proper induced
draft blower performance.

SOURCE: furnace blower not working how it should

first off buy yourself a honeywell stat, in my personal opinion lux stats are garbage, I have run into so many that are bad stats !!! but as far as your fan not shuting down, sounds to me like your fan center on your circuit board is bad and will not shut down the fan when needed, you will have to replace the circuit board, as the fan center is a part of the whole of the circuit board, hope that helps

SOURCE: I have a Coleman furnace model number 7681-8171/b.

Short of being able to look at everything Its impossible to say exactly what the trouble is. Does the board have a blink code showing and a legend that says what this is? What fuel are you on NG or LP? What does the flame look like (if you can see it) IE a lot of yellow, Some orange and Blue...?. Did anyone else look at the system and the thermostat? Does it have AC or HP on it too?

The only 1 thing I may be able to offer is this. On your thermostat (if it is not electronic) there is a needle pointer that points to a number it should be around .4 to .7 if set to a lower number the thermostat will cut the unit off well before it completes a heat cycle.

I have a coleman furnace model 4066A656


Make sure your air filter is clean. Is the thermostat satisfied? or is the room temp. still below the thermostat setting? When ever you have to turn the power off and then back on to a furnace that usually indicates that the furnaces ignition control locked out. The first thing that I would try is cleaning the flame rod.

Pilot and burner light then gas shut off model 7900


How many degrees before it reaches desired temp, does it shut off? A thermostat is designed to shut the furnace off a couple/ few degrees before it reaches set temp. It has what is called a heat anticipater, which shuts the burner down, and lets the blower use the remaining heat from the heat exchanger to bring it up to desired temp making it more efficient. If it is more than a few degrees, replace the thermostat. You can jump out the red and white wires to confirm the faulty thermostat. If by doing this, the furnace never shuts down, until you separate the red and white wires. That confirms a faulty thermostat. Hope this helps someone.

First, for those of you who might not know, "What is a flame sensor?" A flame sensor is a safety device. When your furnace's main burners ignite (light Up) the flame sensor picks up the heat from the furnace's main burning and says, "YES," and sends a signal back to the main furnace control board saying that it is OK to let the main burner stay on. Or if the main burners do not ignite, the flame sensor does not pick up the heat and says, "NO" to the main control board, Shut That Gas Valve and Main Burners Down! Thank God we have safety controls like the flame sensor. Most of the time, after turning your furnace's power off, you may clean the flame sensors with light sand cloth, emery cloth or steel wool. Reinstall the flame sensor and you are back in business! Over the years flame sensors can build up a light coating of burned-in dust and dirt. This insulates the flame sensor so that it doesn't sense the heat of the flame well enough, so by cleaning it you have almost restored it to its new condition. Seldom, but sometimes they do go out completely.

Turn up t-stat, circ fan runs, hot surface igniter glows burner lights blows warm for a short time and then goes cold, flashes 1 flash, ignition problem, no flame when acting up. model# DGAA070BDTB.


The thermocouple lets the control know the flame is burning, and if it doesn't sense flame it shuts off just what you describe. Sounds as though you need to replace the thermocouple.

Is the flame spreading all the way across the burners within 2 seconds? If not clean the flame tray. If it is and the flame still goes out, you have either a poor ground wire connection or the circuit board is bad. Keep your chin up and thanks for helping others.

My furnace will not restart after it reaches the desired temp, then drops below that temp. The on light flashes


If this is a gas furnace, the thermocouple is one likely point of failure. It could also be a clogged pilot light jet.
