In my house, the heater basically stops working every year and my dad put some like “bandaid” solution over it with manipulating some wiring, idk what they do. But like, every year, the heater would stop working like several times throughout the winter and constanly needs to be fixed. But this year it just stopped working completely. Like I google it and those heaters are like $2000 to $2500 brand new, so yea, I get it, parents want to save money, but like, having the heat stop few times a year feels like living in a developing country tbh 😓. So now I’m basically just relying on those portable heater things to stay warm, and my cat is feeling too cold so she’s staying in bedrooms most of the time because its where the portable heaters are at, when she normally just wanders the entire house.
The induction fan induces air to move out the exhaust before the combustion starts, so exhaust gas is ensured to exit the right direction.
If the furnace thinks the induction motor isn’t running or there isn’t a slight vacuum in the chamber right before the induction fan then it won’t light for safety reasons.
I’m my case it was a loose wire on the pressure sensor. Cost me a couple hours to figure out and a paper clip to fix. Been fine for 3 years since now.
