My Carrier Weathermaker 8000 a few days ago the air began to blow non stop and the burners are not igniting. I am getting Code 33. I did all the resets, unplug control board, switch to air condition nothing. The air is still blowing non stop. To stop it I need to shut it off by main switch on furnace. Any fix suggestions?

Are the tips of the flame blue? You might need to adjust the air mixture sleeve on the burner.

Could well be the inducer motor Google carrier 31fault code there are 3 video's on this on u tube

Here is a link that might help. Even if it glows, it could still be bad, but it needs to prove air flow as well. Carrier Weathermaker 8000 Ignition Problem DoItYourself com Community...

33 is a limit switch open take your furnace doors off and there should be a wiring diagram. on this furnace the blower will run if this is open. check rool out swict and linits. it sounds like you have a problem with over heating. how does the fire look ? is the vent blocked ? things like thathttp://www.scribd.com/doc/20861415/Carrier-58pav-Service-Maint i think page 9 has falt codes

you have a dirty flame sensor. just needs mantenance.

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).

call the furnace repairman. you have a fairly easy repair but the parts are expensive

having a problem with a weather maker 8000. It will not come on at all unless I shut down the switch on the side of the furnace. filters is clean. it will start to light then stop

1. check indoor unit wiring.
2 check sensar of thermostate.
3if not change thermostate

. 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.
