So on Thanksgiving my Smoke Hollow decided not to work properly. It would only go to 225 on high. Then when I put turkey in it crashed to 195 an took forever to re coop. Thought it might be regulator since its 11 yrs old. Today had time to look at it. Took apart hoses & valve. Found a cobweb in the piece on the back of valve that's on the smoker. I guess it would be called the orifice (spelling??) It wasn't totally clogged but looked like there was a screen in it. Blew it out with air compressor. Put everything back together. Now running at 243 with chicken thighs in it on low. Also found out the valve is 1/2# psi. Good to know. So if having trouble getting temps up u might want to check this out. Thanks for listening!!!
