I've got a Bryant upflow gas furnace Model #383KAV that quit working last night. I just put a new blower motor inducer motor and a ignighter in and it was working fine. Now when I try to light it all that happens is the blower motor comes on for about 1 minute then it just stops. Normally the inducer motor and the glow stick and then lighting and then the blower motor. The red light will flash 3 quick flashes and 1 long flash. Please help it's cold in here. Thank you.

If code 31

PRESSURE, DRAFT SAFEGUARD, AUXILIARY LIMIT (when used), OR BLOCKED VENT SHUTOFF (when used)SWITCH DID NOT CLOSE OR REOPENED. Then check for:
-Proper vent sizing and condensate pitch or sag
-Vent restriction or high winds
-Defective inducer motor or start capacitor
-Defective pressure switch or connections.If it opens after trial for ignition period blower will come on for 90 second recycle delay
-Inadequate combustion air supply
-Low inducer voltage
-Disconnected or obstructed pressure tubing


This next item is just for your future info. It is about the mounting procedure for your ignitor. While this is probably not your problem right now it could be a problem in the future.
