Hey gang! I have a 40" masterbuilt propane smoker and I am struggling. I fired it up after it sitting for 2-3 months unused. I am in California where the air temp is 70 degrees and humidity is 52%. In theory, I should be having a good smoking day. HOWEVER, my rig will not get above 220 wide open. I made the following mods in the past:
1. added sand to the water tray
2. added a larger water tray that sits on top of the sand.
I had some chickens, spare ribs, and beef ribs in at one time. I got a bit nervous and moved the chicken to the weber propane and have removed the water tray from the smoker. smoker temp will not get above 220. I am using a separate oven thermometer and thought that may be the problem and switched it with another oven thermometer. Both are fluctuating between 210 and 220.
