I love my MES but it sucks when it is cold. Went to turn it on the other night to smoke two briskets and got the clicking noise. Brought the controller inside to warm it up. Took it back out after a while and the LED lit up but after being on for two hours - the only thing that the temp would read was 32. Outside temperature was about 18. Ended up putting the shoulders in the oven. Hooked it back up today. It was slightly warmer - in the 20's and same thing. Why is the element not heating up?
