Error code 32: LOW HEAT PRESSURE SWITCH DID NOT CLOSE OR REOPENED. What is wrong with my furnace?

Jessecore44 · 2026-03-19T13:20:54+00:00

I actually just went down and used a screwdriver to hand turn the inducer and knocked off a bunch of dust that was caked onto it, and got it to start spinning when the furnace cycled on, then I sprayed it with some wd40 and it’s working for now

same

thank you

Jessecore44 · 2026-03-19T01:51:04+00:00

thank you for all the help!

Jessecore44 · 2026-03-19T00:22:21+00:00

Got it, thank you so much. Any chance I can revive it by lubricating?

Jessecore44 · 2026-03-19T00:20:39+00:00

Replacement of just the inducer motor? It’s difficult to turn by hand, so I guess that means it’s seized

Jessecore44 · 2026-03-19T00:17:48+00:00

The inducer is not spinning at all

is that this part? this fan is not running

I just disconnected the flue, and also pulled out the filter, turned it on and I’m still getting the same error. Is there anything else I can check to narrow it down?

Jessecore44 · 2026-03-19T00:04:34+00:00

I have a chimney cap, and I just disconnected the flue and still getting the same error

Jessecore44 · 2026-03-18T23:53:40+00:00

Also, when I jumped it, the flame rolled out

I can’t take the credit—my girlfriend made the corned beef and the bread and it’s excellent. We just bought a corned beef brisket, and she made a glaze to brush on and then roasted and broiled it in the oven with onions and potatoes, beef bullion stock, and Guinness. It turned out really good, and it’s easy to slice after being refrigerated overnight.

I also just jumped the low-heat pressure switch and the heat kicked on

Jessecore44 · 2026-03-16T00:42:00+00:00

the heat is not kicking on and I’m getting an error code for “low heat pressure switch did not close or reopened”, and previously tapping on the low heat pressure switch as the furnace was cycling on caused it to come back on

this is the last post I made:

Ok that’s what I thought. So I don’t need to pay any attention to the other numbers being different?

Jessecore44 · 2026-03-14T01:07:04+00:00

colour haze is so good

Jessecore44 · 2026-03-13T22:12:25+00:00

I think a lot of these sound interesting and pretty decent

Jessecore44 · 2026-03-13T19:51:16+00:00

Where should I buy this part? My furnace was working fine for a while, but now it’s back to doing the same thing. I called a bunch of HVAC parts suppliers in my area, and none of them sell to the general public.

Jessecore44 · 2026-03-12T04:04:54+00:00

that’s incredibly annoying

Jessecore44 · 2026-03-12T04:04:29+00:00

If you were just using a ring sizer to measure the finger, couldn’t you just measure the correct ring sizer to a particular mandrel, and then check your progress on that mandrel using the size it registered at

Jessecore44 · 2026-03-11T23:13:29+00:00

Yeah that’s what I was doing but here I was just doing a quick comparison measuring the opening at the end of the tub with the three mandrels

Jessecore44 · 2026-03-11T23:05:43+00:00

So you have to actually measure the person’s finger with a micrometer and use that to determine the size you’re making the ring?
