Does this code come and go on its own?
is the furnace blower running?
Is the light on the circuit board in furnace solid or blinking?
thank you....now the blinking light...
we are looking at a series of short then long flashes.
Ex: short short short...long long =32
Can you tell me what yours is?
tape the button down.
for 90 seconds you will get that flash.
Then the flash will change....pay close attaention to the pattern.
By the way...was the filter plugged when this started?
great...check the cod flash after 90 seconds and we will go from there
ok terrific....when it starts after the 90 seconds...does the exhaust fan in the top start and run?
And does your furnace vent outside through a chimney or plastic pipes....or I need model number.
I know what the fault is now so we can get started
Now this will go quicker if you can post a picture of the furnace with the doors off so I can draw what to check.....or I need model number to get pictures..
Excellent! see here
now try another cycle...
yes please...tube back in position
if you cannot see the button give me a close up shot of it and I can tell
Then...start furnace again.
90 seconds..check blinks...start count with short blinks first then long...then tell me new code
please verify on the back of the blower door that 32 refers to pressure switch not closing
is there a chance the code is different?
are we positive of the short blinks...then long...short blinks...then long...
and to verify...the small motor by the tube we removed does kick on and run?
and what about this here
can you remove the fuse and show me a pic of the side?
you are correct..it does look good.
32 is a low pressure switch fail
Your model appears to not be equipped with a "dual" hi/low pressure switch.
If the code is indeed 32...then you likely have a circuit board condition.
The induce (exhaust motor) starts after 90 seconds...then the air flow it creates is supposed pull air through that tube and suction that switch at the end and close a micro switch.
But with then an absense of 32 of your legend indicates a internal board issue.
I guess this is one better looked at on site.
I wish you the best and feel free to stop back for follow up after you have it looked at.
