Hello All

I have a customer thats experiencing fan problems on her gas
fireplace.

The fan wall switch has two settings hi and low. I can see the fan
spinning on different speeds and it's going in the right direction.
However this translates to virtually no air flow out the top. Barely
perceptable on hi and nothing on low.

What do you think is happening here? Could the vent be plugged??

BTW I do have some gas pro's scheduled to come. An electrician stated
everything was fine just a couple days ago.

Thanks
Dale
