Hello everyone. This is the first time I am using this site.

Earlier today, I noticed a strange noise from my forced air furnace. I believe it is from the induced draft blower motor due to a bad bearing. I have to admit the noise is not as loud as earlier, and I have not done anything to make it quieter! So I think it will go bad soon. I am wondering whether there is any fire hazard if the blower is seized before I get a chance to change it? Or the system stops flowing gas if the motor stops woorking. Thanks.
