Hello, I have a Temco woodburning fireplace and have used it only a few times since having our home built. I was checking it out this morning and turned on the blower fan switch and the blower motor is making a vibrating sound, but is operating normally. I took off the front panel to view the fan and motor and all appears to be functioning properly. I am a good do it my self fixer, just not quite sure where to begin with this?!
I believe Tempco is out of business, so just take a look and see if it moves by hand and then see what is not securing it. or maybe a better way is to have a local Certified Chimney Sweep www.csia.org, (there you can look up by zip code to find one near you) take a first hand look at what you have they should be able to help.
