I also have the Auber WiFi PID controller. It has an easy mod to use it. It is basically one jumper wire for mine. My Masterbuilt was also having the crazy temp swings and inaccurate temps. I contacted Masterbuilt and they finally sent me a new controller, but I decided to go with the PID controller instead. The great thing about the Auber WiFi PID controller is it doesn’t have to be used only for a single smoker or unit. It can control other things also. Well worth the investment.
I purchased the MB40 back in December and immediately noticed that it took hours and hours longer than any of my previous MB30 models. I just assumed that it was the weather that was responsible but as the weather warmed I didn’t notice any change. I checked the smoker temps with an oven thermometer, a new dual probe thermometer and the built in probe on the smoker itself. The unit maxes at 275 degrees yet the built in probe showed a temp of 400! The remote for the Masterbuilt showed a temp of 144. The dual probe was 205, and the oven thermometer also around the 200 mark. So…
I called Masterbuilt last Friday and spent over 60 minutes on hold waiting for assistance. Grilling and smoking is a popular weekend activity…I get it. Once I got the rep on the phone she asked the necessary questions and quickly determined that I have a control panel issue and offered to send a new one free of charge.
The new one should arrive next week and I will surely put it to the test. Aside from the long wait time on the phone I am very satisfied with Masterbuilt’s response. I’ll keep you posted on the performance with the new control panel. Hopefully that will solve my woes.
Joe Hell I picked up that same smoker the 40 inch at Academy on clearance for 75 bucks! I used it to smoke snack sticks and have had no issues with mine at all. Both the 30 and 40 I run now and work well. Glad to hear they are taking care of the issue at least.
deplorablenc1 D**n…I thought I got a good deal for $175! I’ve used and abused all of my 30’s until they died. They last a couple a couple years before I manage to kill them. Still good bang for the buck…you can almost always find them on sale for a good deal.
That’s why I made my own masterbuilt.
Joe Hell I bought my 2nd MB40 due to my old MB40 controller going bad during the pre-heating process. I turned it on and went inside to mix a 25lb batch of snack sticks. When I came back out, the controller wouldn’t allow me to adjust the temp. Well, I couldn’t let 25lbs of meat go to waste, so I went to the nearest Academy sports and paid full price. $299
I repaired the old one, so now I have 2 MB40’s.
rhjbarney I will try that someday! There are some truly ambitious home builds on this site. You do great work!
For the Masterbuilt look at getting a Auber Wifi PID controller, it works awesome, very accurate and stable temps. Also look at getting a cold smoke attachement, much better smoke for hot smoking plus added benefit of being able to cold smoke. Electrics are notorious for having trouble producing smoke at lower temps. A alternative to cold smoke attachment would be to make a Mailbox mod for the smoker. It does the same thing.
