Invaluable information, thanks, hear of this one time only but the other tech never found the issue that I know of.

you do mean valuable?

[kdean1]

you do mean valuable?

"invaluable
in·val·u·a·ble
adjective beyond calculable or appraisable value; of inestimable worth; priceless"

Valuable/invaluable - the same
Flammable/inflammable - the same
English is weird.

Lol I guess what I meant was invaluable as in so useful you can't put a price on it, seems like I heard that expression somewhere but maybe I got it wrong. So yes unmeasurable value.

[gravity]

thank you kdean and joe.

the English language is pretty jacked up.

to, too, two, there, their, they're.....etc

Never would have crossed my mind. How many furnaces have this "restrictor plate"?

This site is unvaluably inmeasurable.

Every nordyne furnace has one since they all use the same inducer (within a model series). A 60k btu will have a restrictor with a small hole, while a 120k will have one with a big hole.

The faulty restrictors seem to be on models made in the early to mid 2000s. They were made from an opaque plastic that flakes away. The problem is most pronounced on units where the filter was not changed often enough.

And the restrictor is part of the inducer assembly which, if changed, will remedy the issue?

No the inducer orifice is separate, and snaps into the opening in the Front Header Box. Then the inducer assembly is installed over it.

As Crag1 said, same inducer, you just use a different orifice to control the airflow.

See attachment (sorry, picture is a little fuzzy).

[hurtinhvac]

Got it. Picture is fine.

Most instructive as always, Rundawg.

Thanks all for this thread - had no clue.

[iowa tech]

so is Inducer Orifice in blower or Header Box?

[Joehvac25]

On the g26 you buy an inducer and it comes with multiple restrictor plates and based on BTU the correct color plate gets installed in the inducer, I'm sure some have them in condensate box as well?

[rundawg]

It does snap into the Inducer Motor Assembly, and not the header box on this particular unit.

I stated it wrong on my previous post. What I was trying to say is the Orifice is between the inducer and header box.
