I just had this installed and used it for 1 full day and now when I push the ACC the timer ticks for 10 seconds and i will wait 20 mins or the next time I load wood and it seems to be open/no resistance when I push the lever in. When I removed the faceplate and moved the acc by hand it opened and closed. Can anyone tell me a way to adjust the mechanism or where to look for why it is stuck. Thank you
