i am doing my 2nd smoke on my 18.5 wsm and also trying my maverick redi chek temp monitor for first time.

At first, the smoker temp on the maverick was same as shown on the wsm but after about 45 mins or less, the temp on the wsm showing about 25F less than that showing on maverick.

I thought the maverick was defected but tried the temp gauge that came with my performer and gave me similar temp to that shown on the maverick.

It seems like the WSM temp gauge is off.

Dis anyone have defected temp gauges on their WSM?

I wouldn't worry about a 25 dif in temp at all Elmo.
Pick one temp, lid or grate and you will be fine.

25* between grate and dome is pretty standard, like Timothy said pick one, preferably the grate, and go with it.

Towards the end of the cook, the difference was as big as 40 F.

I was doing some reading and it is supposed to be hotter temp at the lid and not at the grate. I am getting the opposite. That is weird.

Hi Elmo.
If you do a search on lid vs grate, you'll see that your difference in temp, is not that uncommon.

Reminder.... Check your thermometers in boiling water so you know how they read. If they are bimetal with adjustment screws, calibrate them.
