Just purchased the series 3 verticle and right after the initial 45 minute burn in got the ErL error. Tried the full open chimney didn't help. Could not get past the error code. Called support and chose the call back feature because of long hold time. About 7-8 hours later they called back. Support said it was a bad temp probe and they would send a replacement 6-8 weeks. Took the smoker back to store and got a replacement. Fired the 2nd new unit up and got same ErL code on initial burn off. Auger seems to be working fine when using the "prime" button. Going to try the Amazon temp replacement to see if it does the trick. Any other suggestions?
