It sounds like your furnace one of two things..... once reset, it could be running up to an overtemp condition and is tripping the high temperature limit switch. This typically locks on the blower and the inducer fan and locks out the gas control until the circuit is reset, then it does it all over again. Dirty filter or dirty evaporator coil restricting air flow is a typical culprit.

The other thing could be a tiny bit of oxidation INSIDE the barbed port of the inducer fan where the pressure switch tube slides on. This could be causing either a restriction or a blockage of the positive or negative air pressure required to close a pressure switch when the inducer starts. This will result in a normal sequence up until the gas valve needs to open.

Neither of these suggestions are specifically typical to what you describe, but are two good things to check considering the numbers of parts already installed.

OK, if the furnace is not lighting for even a few seconds, you have either a bad gas valve, bad wire, bad control module or no gas. The pressure switch is not the issue. Check all wires to the gas valve and look for 24 volts across them when the ignitor glows and you hear the click. Then test for 24 volts to ground. It could be a bad ground wire.

SOURCE: FURNACE COMES ON AND SHUTS DOWN WITHIN 15 SECONDS

On a call for heat, the 24 volt thermostat sends a signal to the control module. The control module will indicate a call for heat with a light on the control either blinking or remain solid depending upon model. The inducer (exhaust) blower will purge all gasses from the furnace and pressurize a pressure switch. Once the pressure switch tells the module to continue, the electronic ignition will energize and send 120 volts to the igniter. The igniter will glow and you will be able to see it if viewed thru the small inspection port. Once the igniter gets hot enough, it sends a signal to the module opening up the gas valve (24 volts). Either a pilot will come on or the burner tube will ignite then spread the flame to all burners. Lastly a safety sensor will be looking for a certain temperature within a few seconds and the furnace will continue to operate and the room air blower will turn on in a minute or two.

What could go wrong? The unit will not run if there is no signal from the thermostat (bad thermostat or broken wire), the control module does not sense a signal from the thermostat (bad control), the inducer does not energize (bad motor), the pressure switch does not close (blocked vent piping, bad switch, plugged condensate hose), the igniter does not energize (bad control, bad igniter), the gas valve does not open or there is no gas (bad gas valve, broken wire, no gas), the pilot does not light (dirty pilot), the burner does not light (bad burner, plugged orifice, not enough combustion air), the flame does not spread to each burner (bad flame spreader, dirty flame spreader, more bad burners), the flame safety sensor does not detect flame (dirty or bad flame spreader, bad flame sensor, broken wire, bad control), or the room air blower does not energize (bad fan motor, bad control). When all else fails, check the ground connection for corrosion.

SOURCE: Gas furnace; flame will not stay on

Clean the flame sensor with a green scotch brite pad. Check all ground connections from the circuit board to the furnace cabinet. Check for a proper ground to the electrical box. Make sure polarity has not been reversed.

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.

Troubleshooting and Repair
Furnaces with electronic ignition systems may be much more efficient than their early counterparts, but they do it largely through electronics. However, there are still some troubleshooting you can do but fixing the problems can involve replacement of parts more so than repair or adjustment. PROBLEM: Furnace burner will not ignite
Possible Solution
  • With a Hot Surface Ignition (HSI) system, if a gas hissing sound is heard for about 7-10 seconds and the burners do not ignite, the furnace will go into lockout mode.
  • To reset turn the furnace power switch off and back on and try again. The switch is probably located on the side of the furnace. A reset button may also be found on the solid state controller. If resetting fails again, proceed as follows.
  • Turn off power and gas to the furnace
  • Remove and check hot surface igniter being careful not to touch the heat element. If it is cracked or damaged, replace the igniter.
      PROBLEM: Furnace comes on for 7-10 seconds then turns off Possible Solution:
      • Turn off power and gas to the furnace
      • Remove flame sensor from its bracket. Lightly clean the surface with fine emery cloth and replace.
      • The problem may also lie in a bad ground or the the black and white wires being reversed (reversed polarity) at the junction box or outlet powering the furnace.
      • The electronic ignition control module must ensure current flow through the flame sensor to ground and if the polarity is reversed in the circuit there is no voltage potential and the flame sensor does not work and closes the gas valve.
      • If the black and white wires are connected correctly and the flame still drops out, then the issue may be a bad ground. Using a volt-ohm meter, measure between the white wire and the ground wire to be sure you have no voltage.

Carrier Gas Furnace and Hunter Thermostat not working


Definitely a furnace issue. The gas valve is not opening if you see no flame. I have seen the igniter glow but not send enough voltage to the circuit board to make the gas valve open. If this is the case you should replace the igniter. It is very fragile so please use care when replacing. Check all connections at the circuit board as well as the gas valve. Check your gas supply. Check to see if you get 24 volts AC to the gas valve. If no, replace the circuit board. If yes, replace the gas valve once you confirm that you have gas to it. If you get a pilot flame only, you will need to clean the burners and flame tray that spreads the flame from one burner to the next.

Turn off at tstat and then put a voltmeter across the terminal at the gas valve Should be three wires there Go across the common and 1st stage. The force fan comes on the ignitor and then the gas valve. If no voltage is at the gas valve check limit switches. Also on this furnace if you look in the fan compartment thru the smaal glass inspection hole the lights blinking should tell you the codes. open open rollout and so on. With your experience you should be able to tell whats going on make sure gas valve is turned on on top of gas valve. FEEDBACK WELCOME KEEP IN TOUCH r

Furnace won't stay running


1
1 FLASH
Furnace fails to operate.
• Integrated control module
diagnostic LED is
flashing ONE (1) flash.
• Furnace lockout due
to an excessive
number of ignition
“retries” (3 total)1.
• Failure to establish flame.
Cause may be no gas to
burners, front cover
pressure switch stuck open,
bad igniter or igniter
alignment, improper orifices,
or coated/oxidized or
improperly connected flame
sensor.
• Loss of flame after establishment.
Cause may be
interrupted gas supply, lazy
burner flames (improper gas
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.

Your hot surface igniter may be bad. It may be cracked which would prevent it from starting the burner flame.
