Replacement HSI not working
To make a long story short, I bought a rental property and the equipment (Rheem) has not been run in 2 years.
Listening to the sequence of events (gets to the gas valve opening and then quits) I figured the HSI was bad. I tested it and got an OL reading, so I purchased a replacement, it tested at roughly 55 ohms, so I installed it. Went through the same sequence of events and would not glow.
The thing that kind of confused me was the wiring, it doesn't look like its wired in series like my equipment at home. It appears to be wired in parallel next to the Inducer motor on the same plastic bracket on the IFC. I tested the wires and they are not grounded or open. I tested the voltage from the IFC, and got 118 for the inducer motor, but only 0.7 for the HSI, even during the sequence of events.
Could this be a bad IFC? I figured I should ask someone who has far more experience than me (I'm only a tech school grad) before buying a new control board.

Did you take that voltage reading when the HSI is energized? You know that it isnt energized the whole time.
If you did take it at the proper time, and you took the reading from the board, and you STILL had .07v, You got a bad board (and a new HSI lol)Every customer you take for granted today will be someone else's tomorrow.

Smells like DIY to me. In fact, it's a really, really, really strong DIY smell. Yup.If YOU want change, YOU have to first change.
If you are waiting for the 'other guy' to change first, just remember, you're the 'other guy's' other guy. To continue to expect real change when you keep acting the same way as always, is folly. Won't happen. Real change will only happen when a majority of the people change the way they vote!

Very common rookie mistake....HSI doesn't glow, must be bad HSI.
Bad HSI, very very bad HSI, daddy must spank!The picture in my avatar is of the Houston Ship Channel and was taken from my backyard. I like to sit outside and slap mosquitos while watching countless supertankers, barges and cargo ships of every shape and size carry all sorts of deadly toxins to and fro. It's really beautiful at times.....just don't eat the three eyed fish....
