Another fan question

I had the same problem. The fan itself has a solid state circuit inside that inverts and controls the fan voltage. When mine went, it felt like it needed a push start so maybe they got a bad batch. Cookshack sent me a new one free but the fan they sent me had the same type connector as the old one but by a different manufacture and the plugs wouldn't match. I ended up cutting the old fan plug off and splicing it to the new fan.
Also, be aware that Radio Shack carries a computer cooling fan for $20.00 that will replace the stick fan. Since it has a metal frame, you will have to hacksaw off four tabs to get to the mounting screws. I now keep that handy for a backup.

The fan runs all the time in the non IQ4 models (those using the Traeger controller). In the IQ's, it turns off when the temp is reached and back on as needed.

Thanks for the reply Larry. I still dont know if the fan slows down or stops then stats again while running. I think when the smoker gets up to temp it slows way down, then when temp falls it kicks back on. It must have stopped during the brisket cook or had a flameout and dumped pellets on the embers that were left in the pot. Think i need to call cs tommorow

Thanks Smokin Okie, fan seems to have a problem starting from the stopped position, I carried my wireless around all day to watch for temp drops. Kinda kills the idea of set it and forget it lol
