No Heat From The Unit
 
Howdy,
Three year old unit has been working fine until I tried the heat last night. At first it's just regular cool air flowing and then after 5 or 6 minutes just stops all together. I tried decipering the user manual and it says to make sure the light is burning. I look through the hole and No Light. I look for the ignitor and I don't see one anywhere.

I googled the model number G6RC-080C-16B and couldn't find any information. I tried Nordyne.com and it wasn't helpful at all.

I know that this is not much information to go off of, but.....HELP!

looks like the install guide for your furnace series.

Of particular interest is page 36. You need to observe the flashes of the red status light in order to determine what the problem is.

Your model decipher : (http://www.nordyne.com/Literature/400a.pdf)
G(Gas) 6(Series) R(Residential) C(Upflow, condensing)
080 (80kBtu input) C(Canada) - 16(1600CFM airflow) B(cabinet width 19 3/4")

Couple other things: are you sure furnace is even on? Some homes have Summer/Winter switches that disable the heater. Did you make sure gas supply is on? Sometimes people will turn off the gas to a furnace at heating season end 'just in case' and forget about it.
If by 'ignitor' you mean pilot light, these furnaces don't have it - they use hot surface igiters.

Great place to start!!! Thank you so much for the info. I'll take a look today.

Couple other things: are you sure furnace is even on? I believe so. The air is blowing but not warm air, within a couple of minutes it stops. Some homes have Summer/Winter switches that disable the heater.
Did you make sure gas supply is on? I believe it's on, I never shut it off from last year. I double checked and the handle is in lateral position. Sometimes people will turn off the gas to a furnace at heating season end 'just in case' and forget about it.
If by 'ignitor' you mean pilot light, these furnaces don't have it - they use hot surface igiters. That explains why the manual says "not pictured".

Remember, forced air system allow furnce blower to be operated independent of heater, in order to profide flow for A/C or fan only ventilation. If main blower comes on, furnace apparently has power.

Refer to the installation guide - the startup procedure on page 32, sequence of operation on page 38. Flashes of the red status light are really the important part. There seem to be a few switches you might need to check/reset. You also might have an open limit somewhere - either due to blocked vent/supply or a problem with a drain line.

Looks like I get two flashes that indicates "pressure switch is open with inducer on"

I get some gurgling from the condensation pump. has to be some blockage somewhere.

How do I clean this out? Someone told me vinegar will disolve grime. Ist true? and if so where do I pour?

Pressure switch open generally means that during pre-purge, blower fails to achieve sufficient air flow down intake/exhaust. Examine their terminations for blockage. And yeah, check condensate lines.
