Payne Furnace Cycling Without Heat

[Tom Pav]

Tonight the furnace kept cycling without heating the house.  I initially had Error Code 12, realized the filter was disgusting (just installed cabinets and flooring on remodel with cutting in the house).  Too late to find a new filter, so kind of picked most the dirt out and reinstalled it.

Still cycling, but now have Error Code 34.

Unfortunately I'm in Oregon in the middle of a snow storm and can't get anyone out here for days (it's 10 degrees right now and we have a few feet of snow).

Does anyone have any idea of what the problem could be and how I might fix or at least patch it until I can get a svc call?  If I were able to find a new filter would the fix be that simple? Or is there some kind of trip switch I need to reset/replace? Or....?

Thanks in advance,

Tom

(cold and sober -- hopefully I'll be neither tomorrow night!)

We need more information.  The error code list should be inside one of the cover panels explaining what a error code 12 and 34 means. 

Sequence of operation is as follows. 

1) Call for heat.  HEY HEAT, GET YOUR ASS IN HERE!!

2) Inducer motor kicks on (if so equipped) closing the pressure switch. I just can't stand the pressure!!

3) Igniter glows.  Isn't that a purty orange color??

4) Gas valve opens.  Ahhh, FIRE!!!

5) Blower motor kicks in after a couple of minutes.  Arr, blow me down.

The model number is PG9MAB

Fault Codes are:

Fault Code 12         Power Interruption or Furnace Powered Up

Checklist    During a Call for Heat Blower will run for 90 sec before furnace starts a normal heating cycle.  

Code  14 or 34        Ignition Lockout or Ignition Proving Fault

Check to be sure manual shutoff valve in gas supply pipe is in the open position. (Follow start-up procedure if you open gas line.)

NOTE: Turn off the electrical supply and remove access doors before continuing with this checklist.  

Check to be sure control switch or knob on gas valve is in ON position. (Follow start-up procedures if you must reset switch or knob to ON.)

Here is the cycle of what is happening:

1) Black wheel spins on Blower Box

2)  Orange Glow from Pilot Box area

3) Hear a click

4) Blue flame flicker from Pilot Box area

5) Flame out, no blue or orange glow

6) Notice LED no longer solid and blinking Code 34

7) Blowing air through vents

8) Everything off

The above sequence keeps repeating (except for #6 which stays in Code 34).

Sorry for the above layman explanation and not sure if Blower Box or Pilot Box are correct terms.  But I would appreciate anyone trying to help me fix or at least patch this until I can get someone to fix it.

THANKS,

Tom

PROBLEM SOLVED

I realized it was an airflow, but was stuck on the dirty filter issue when I should have realized I have almost two feet of snow on my roof.

I climbed up the roof and sure enough the vent is below the snow line.  There was a hole in the snow making it easy enough to find, I was already on all fours, so just made some snow angels on my roof to clear the snow, headed back into the house, hit the breaker switch to the furnace and ALL IS GOOD!

Have an awesome holiday everyone.

Glad you were able to figure it out!!

That makes sense.  With the vent plugged, that would prevent the inducer from closing the pressure switch.  Good job of self diagnosis there TomPav.
