It may be a little difficult to diagnose if you don't have a volt/ohm meter to check the switches with, but I will try to help what I can.

The first thing to check is the pressure hose from the vent fan to the pressure switch. Make sure there is no hole rubbed in it and make sure the connector on the fan shroud is clear. Stick a piece of wire in it to make sure a dirt dobber has not clogged it up. Blow in the hose and listen for the switch to click. If there are only 2 wires on the switch, use a piece of wire to jump across them and that will take the switch out of the system. This will tell you if the other parts are working properly.
Post back with what you find and I will try to help. I don't have a digram in front of me, just working from memory, so please be patient.

SOURCE: Carrier Weathermaker gas 8000 will not ignite

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

SOURCE: Carrier Weathermaker SX model 58SX060-CC Blower runs all the time

Remove all power from the furnace, it is likely the brain in the furnace is need of being reset, from the battery replacement, why did you change the battery, was there an indicator telling you to change it?

Many times just removing all the power to the furnace will do the trick with a reset, if not let me know and we will go from there, but it sounds like the main brain is confused or bad, more likely confused, so try the power removed first.

Than let me know wbwill@sbcglobal.net

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.

Looking for sequence of operation for a lennox mid efficient furnace


When there is a Call for heat, the control delays ignition until combustion air

Blower operation has been proved and pre-purge period

Has elapsed. It then opens the gas valve and generates a

Spark to ignite the burners. Trial for ignition lasts for 7 seconds.

At the same time, the control begins monitoring the

Flame sensor. If the flame current is too weak (less than 1

Micro amp) or if the burners do not ignite (within the 7 second

Ignition trial), the control will shut off spark and the combustion

Air blower and de-energize the gas valve. Flame

Current should be between 1 and 5 micro amps to keep the

Gas valve open.

The control will attempt to ignite the burners up to two more

Times. Each time the control restarts the ignition sequence,

It begins with a 45 second pre-purge. If flame is not sensed

After the third trial, the control locks out. Lockout means that

The control shuts off the gas valve, spark and combustion air

Blower for 60 minutes. At the end of 60 minutes the control

Completely resets and will attempt ignition up to three times.

The control can be manually reset before the end of 60 minutes

By momentarily turning off power to the unit.

here is a link to an operations manual

Remove them and scrub them with a wire brush.
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).

Having problems with Carrier 58RAV furnace. Goes through the motions, but gas never turns on. I think it is a problem with the LPGS. Please advise. Thanks

Furnace wont run


First of all when you flip the switch, it goes thru a startup sequence. THEN it turns on the Igniter (notice the red glow). Then the gas turns on.

Now at this point check the idiot light and it should be giving you a code of 34. That 34 (3 shorts 4 longs) says that there was a problem igniting the furnace. After it cycles thru at least 4 times and fails to ignite all the blowers, then is when you get a code 14 (1 short 3 longs)

NOTICE what's happening with ALL the burner Tubes each time it attempts to ignite. If only one or two are running....then this is your problem.
To fix all you do is take out the burner Tubes, look for debris, blow them out (blow from the front where all the jets are), and replace them in sequence from left to right (the tabs overlap).

Carrier furnace weathermaker 8000


. Several times of recyling power normally brings the furnance up. Though the failure code has always been 31, there are several different behaviour when the blower starts after reset :
a. blower simply creases.
b. there is an attempt to start the heating unit (I hear the high pitch noises), then everything stops.
c. there is an attempt to start the heating unit (I hear the high pitch noises), once I see the orange glow from the coil, normally the gas is lit up and the unit starts working.
