15 year old Rheem RGDG10E furnace

[lestouffer]

I 've got a 15 year old Rheem furnace which has decided not to work this winter. This year, We have replaced the HSI, but it is defective. So we need to get a new one. We have also replaced the blower motor. It sounds a lot better, but it still isn't working.

Do we need to look for defective part #3 or should we get a functional HSI and start again?

There has been no smell of gas or anything.
