I checked the resistance of the HSI and it's around 99 ohms. The furnace was working earlier tonight. I turned it off to check the blowers and when I turned the gas and electricity back on, it stopped working.

Hello and thanks for using this service, if you have been waiting do not worry or get upset I am just one of the techs on here and I try to get to as many customers as I can and I just picked up your question now. Please give me time to respond sometimes I get your replies late so there may be a delay in my response.

Can you check if the ignitor has power to it when the unit comes on and the exhaust fan starts up?

Customer: replied 11 months ago.
How do I check if the ignitor has power to it? I just found out that I'm getting an error code #32 (3 short and 2 long LED blinks)
Expert:  HVAC Guru replied 11 months ago.

That is a pressure switch fault, is the exhaust fan running and is the rubber tube and port clear from the inducer housing to the pressure switch. The port where the rubber tube connects often gets blocked or the exhaust port itself could be blocked, check that.

The small blower is running. I checked the ignitor - disconnected the HSI wires and put my multimeter on voltage and measured the female plug - no voltage. I am not sure how to check if the rubber tube and port clear from the inducer housing
Expert:  HVAC Guru replied 11 months ago.

Find the rubber pressure tube on the exhaust blower housing and pull it off and see if the port is clear.

Customer: replied 11 months ago.
ok. give me a minute
Expert:  HVAC Guru replied 11 months ago.

ok

Customer: replied 11 months ago.
I removed the tube from both the housing and sensor - it's clear. I blew through the tube. I also disconnected the smaller rubber tube between the two sensors and that is clear. There's a metal tube that the rubber tube connects to in the exhaust housing and that appears clear too.
Expert:  HVAC Guru replied 11 months ago.

Ok check the exhaust port outside to make sure it is clear and you can feel air moving out when the exhaust fan is on.

Customer: replied 11 months ago.
How do I check that? Do I need to remove the metal pipe that is screwed onto the housing?
Customer: replied 11 months ago.

You can or just go outside and check the pipe at the outlet.

It's on my roof - need a ladder. Give me a few more minutes.
Expert:  HVAC Guru replied 11 months ago.

ok

Customer: replied 11 months ago.
I just removed the pipe from the housing. It seems to blow a little air - not a ton although I'm not sure what "normal" is like.
Expert:  HVAC Guru replied 11 months ago.

If it is blowing air then the pressure tube port should have a slight vacuum on it. If so you likely have a bad pressure switch on the unit that is where the tube connects to on the other end. If so you can try to bypass it to see if it works by connecting the 2 wires to the pressure switch together when the fan comes on for a call for heat If it starts up and lights then replace the pressure switch.

there appears to be 2 pressure switches. which one do I connect the 2 wires between? There's a "Low Fire" and "High Fire" and they both say BA20115
Expert:  HVAC Guru replied 11 months ago.

The Low fire one

Customer: replied 11 months ago.
I connected the two wires from the back of the Low Fire switch and I got a #23 error - "pressure switch did not open"
Expert:  HVAC Guru replied 11 months ago.

You have to do it in order (sequence), wait until the fan comes on and then put them together.

Customer: replied 11 months ago.
Do I need to wait for the fan to come on and then connect the two wires while the fan is running? I connected the two wires and then turned the unit on.
Customer: replied 11 months ago.
Got it. I will try that
Expert:  HVAC Guru replied 11 months ago.

ok

Customer: replied 11 months ago.
Ok. I got the HSI to come on by bypassing the pressure switch
Customer: replied 11 months ago.
Seems like a bad pressure switch from process of elimination
Customer: replied 11 months ago.
Do I need to replace both switches on the unit or can I just replace the Low Fire switch?
Expert:  HVAC Guru replied 11 months ago.

Just replace the low fire one.
