I've got an old Fraser-Johnston oil burning furnace.
Info: Commercial Standard CS-195-60
Last night it decided to start squealing at me. It squeals on heat, A/C or fan only. So should I assume that its a bearing on the fan/blower? Anyone know what part#/mfr. it'll need? Can I run it for a little while before it completely burns out? The noise is bearable as long as I'm not in the basement where it's located.
