Re: Where to buy silicone sealant for boiler blower assembly

It's also likely it's not the motor or the capacitor. The squirrel cage they use on those draft inducers (as you can see in the photo) aren't made out of the best steel. One of the byproducts of combustion is H2O (water), so the blower wheels will literally disintegrate inside the housing due to rust. Have you taken the assembly out of the boiler and looked at the squirrel cage?

As far as the high temperature silicone sealant, most auto parts stores sell it. As far as the capacitor, the specifications should be printed or etched on the capacitor.
