1. Electric Smoker Overheating

Masterbuilt electric smoker overheating is the first problem for people who smoke for the first time with a Masterbuilt digital electric smoker.

The normal temperature of a smoker is 200 to 250 degrees.

 the normal temperature of masterbuilt electric smoker

However, sometimes, some of us notice our Masterbuilt electric smoker temperature is too high and get above heat than normal like 275 or 295 degrees.

Even though, we set all of the dials as low as possible we can, in return, our meat smokes so fast. Don’t worry. Here is the solution.


The possible reason behind overheating the MES of a digital electric smoker is- too much airflow coming from elsewhere.

  • You can get rid of this problem by turning the vent off a little bit. If you need more to close the vent, then do it. 
  • If the smoker has multiple dials, then turn a dial completely off and smoke with just a dial. 
  • Therefore, you can also use a water pan and put ice cubes in the pan. 
  • Using less fuel in the smoker will be another effective way to avoid the overheating issue. 

Trying all of these will help you to get rid of the problem. If anyone of these fails to solve the issue, contact the Masterbuilt support team.

2. Smoker Not Getting Hot Enough

Another problem we often face with MES is- the Masterbuilt electric smoker is not getting hot enough or smoking enough for smoking the meat.

masterbuilt electric smoker not heating up

Here are some reasons why your Masterbuilt is failing to keep holding the set temperature:

  • You may not use the proper fuel
  • The chip tray may come loose
  • The chip tray may remain unclean


Masterbuilt Electric Smoker doesn’t provide enough heat to cook the meat evenly for using improper fuel. In this case, you can use quality wood chips or chunks like oak or hickory

Some of us soak the wood chips to let them not burn quickly. But we recommend you not to soak the wood as it is not heating the smoker enough. 

Another reason behind uneven heating is the chip tray of the smoker. If it comes loose from the burner element, it doesn’t allow enough heat to get to the chips. 

So, you can alleviate this problem by getting it back on the burner element. Also, make sure you clean the chip tray clean and bring it near the burner element. 

Yet if you find the issue is still, then you can read our ultimate solution guide on why your Masterbuilt smoker not getting hot enough.

3. Masterbuilt Smoker Temperature Fluctuations

When you notice your Masterbuilt smoker temperature is swinging, then be sure that the possible culprits are the bad thermostat, leakage on the smoker lid or door and anywhere in the smoker, dirty smoker, and heating element.

Plus, if you frequently open the smoker lid or the lid is slightly opened, you will get the wrong temperature on your Masterbuilt. 

Besides remember, cold weather, bad airflow, smoking too many foods at a time, and changing smoker temperature settings frequently will also lead your Masterbuilt temperature to go up and down while cooking. 

Most importantly, if you use a large pan and it blocks your smoker airflow, you won’t notice a stable temperature on your Masterbuilt. 


Whenever you find your Masterbuilt electric smoker temperature is not accurate and frequently fluctuates, try the following solutions:

  • Check and find out if the thermostat has gone bad or not. If it’s faulty, change it. 
  • Make sure there is no gap on the smoker lid, door, or anywhere in the grill.  
  • Before cooking or after cooking, don’t forget to clean your smoker. Ensure your smoker is cleaned before starting the cooking. 
  • Don’t open the smoker lid often. Keep it closed while cooking. 
  • Place your smoker in a place where the smoker won’t face windy or cold weather while cooking.
  • Use a small size pan and ensure enough airflow. Plus, don’t overfill the water pan.
  • And finally, don’t cook a large amount of food at a time and never change the temperature setting frequently. 

Special Note: When you cook food indoors with your Masterbuilt smoker, it’s normal to swing and + or – 20-30° temperature. You will notice such temperature variation because when the temperature reaches your setting level, the smoker heating element gets cut off automatically. 

But, at that time, the temperature rises until the element becomes cool. It’s the reverse process of getting a low temperature.

With this process, when the temperature reaches a low point of your set temperature, the smoker heating element will again turn on. But at that point, the heating element takes a little time to get hot. 

And for this process, you will notice your set temperature drops for some time. In such temperature swings, you shouldn’t get worried. It’s normal. 

4. Masterbuilt Smoker Reading 300 Degrees & Stuck

When you find your Masterbuilt Digital Electric Smoker sensor stuck at 300°, then be sure the bottom power circuit board is the main culprit. The power circuit board has gone bad.

While facing such a temperature stuck issue at 300 degrees, the only solution is to replace the bottom power circuit board.

Contact the Masterbuilt customer service center and have a new one replaced. It may cost you $75-80. 

5. Masterbuilt Smoker Won’t Go Above 200° Or 150°

The most possible reason behind your electric smoker not going above 200° or 150° is that you might put too cold meat or brisket with bitter cold water in the water pan into an uninsulated smoker chamber. 

masterbuilt electric smoker won't go above 200° or 150°

This too much cold meat and water incorporated with an uninsulated smoker cabinet is keeping your smoker temperature below this level.

So, you can’t expect to raise your smoker’s temperature until the meat temp begins to climb.  


  • Don’t put too much cold meat and water into your smoker chamber to cook. 
  • Insulate the smoker inside before putting the meat and starting your cooking.

6. Smoker Keeps Shutting Off

When your Masterbuilt smoker keeps shutting off and fails to deliver the perfect temperature for smoking, remember, the following 3 possible reasons are working behind it.

masterbuilt smoker keeps shutting off
  • The first reason is the bad control unit. The smoker keeps shutting off if you have MES Generation 2. It comes with controls built into the front edge. Because of this design and bad control, the smoker turns off often. 
  • Plus, a blown fuse in the electric panel is the possible cause of your Masterbuilt electric smoker won’t stay on.
  • Then getting rust can be another cause of your smoker keep shutting off. As you know, with the growth of your smoker age, it gets rust, and that rust affects the power connection and you may notice your Masterbuilt not getting power.


The best solution to Masterbuilt electric smoker digital control problems is just replacing the thermostat temperature control.

Also, make sure there is no loose wire in the digital control or fix the blown fuse. 

Striking with a sharp blow to the left side of the digital control may also fix this problem. However, we recommend you call MB and get a new control. 

Then make sure you clean your smoker perfectly after every use. And don’t forget to keep your smoker in a dry place after cleaning.

You can store the smoker in your garage or your store room. It will prevent your smoker from getting rust.

7. Smoker Temperature Control Issues

Masterbuilt smoker temperature control issues like overheating or not getting enough heat or smoke are some common problems newbies face.


We have already provided the solution to both of the issues in this guide. So, check out the above section again. 

However, you can close down the vent a bit if your smoker gets too hot. On the other hand, do the opposite if your smoker is not getting hot enough. 

Otherwise, call Masterbuilt to get help from their support team. 

Masterbuilt Smoker Temperature Range

The exact temperature to cook in a Masterbuilt electric smoker is from 100-275 °F.

      For the water pan issue, the temperature of your Masterbuilt is not getting over 150. Water slows down the heating process. Its solution is easy, just dump out the water and hopefully, your problem will get solved.
