Ok I am new to this site. I wish I would have found it a year ago. I have been having intermittent issues with my blower(s). I replaced one of them last christmas for 140.00. One month later (cold as heck in january) it quit. The fireplace store warranted it (2weeks shipping). It was in for a week and quit. (made some smell like burnt plastic). turned it on the next day and has worked flawlessly ever since. Sunday I decided to put in the second blower. (I was stingy and only used one) The new blower 84.00. Fired up the fireplace at 9 am. everything wonderful until 11pm. Both blowers quit and it stunk like burnt plastic. I let it set with both switches off for about 5 minutes, I turned on both switches and only one blower started. I turned it off and let the fire burn out. This morning I checked everything (wiring, blower motors etc. ) Everything seemed fine. I called the company I bought the blowers from and they said I had bad switches. Well, we will find out (hopefully) tonite. I replaced both switches and now we will see. Northern wisconsin is getting cold.
