Hey I've had the pit boss 700 for about 8 months. Recently it started being unable to get up to 180 degrees F when I'm trying to smoke something. It will get to around 150 and then trend down until I get the erl code. If I put it really hot it can get up into the 400s, but even that takes longer then it should. I've cleaned it all out. Emptied the hopper and auger to make sure nothing was jammed, and even cleaned the temp probe and still it's not working. Anyone know what wrong with it.
