airheatman :

OK

airheatman :

If I have the correct manual, this indicates the pressure switch is stuck closed

Customer:

sorry typing too fast

Customer:

its orange

airheatman :

Great

Customer:

now what

airheatman :

Now remove the hose from the inducer fan, suck and blow on the hose(still attached to pressure switch) and listen for pressure switch to click open and closed.Then remove hose from pressure switch also,Blow through the hose and make sure it is clean.Take a straightened paper clip and clean the fittings on the inducer and pressure switch to make sure no rust or particles are blocking the vacuum.

Customer:

one moment please

airheatman :

ok

Customer:

Tim - U-da-man!!!

airheatman :

Have you already tried the furnace and did this correct the issue

Customer:

I've go heat!!

airheatman :

Great

Customer:

...got heat

airheatman :

If I have helped. please leave positive feedback

Customer:

it did not appear to have any blockage when I blew - is it that sensitive to particles??

airheatman :

It is not unusual for small particles to get in the inducor from gas burnoff or rust and eventually clog the little fittings or hose

Customer:

is it really worth it buying the expensive filters?

airheatman :

Inducor pulls a vaccum on the switvh closing it.It is not real strong, so it doesnt take much of a restriction to vary the vaccum force

airheatman :

That is a seperate question

airheatman :

(LOL). Just kidding with you. I recommend the pleated filters

Customer:

very funny tim - r those the $5 10 or $15???

airheatman :

LOwes sells a good 3M for around 10 bucks

Customer:

10-4 - will leave positive feedback - Cheers!

airheatman :

Thanks again for allowing me to make your furnace happy.
