Masterbuilt Smoker Keeps Shutting Off [3 Easy Solutions]

Here are three main culprits that cause your Masterbuilt Electric Smoker to shut off continuously. 

01. Bad Controller

A defective control unit or faulty controller is the main culprit behind the Masterbuilt smoker issue. Your smoker will keep shutting off after 5 minutes every time you turn it on if the controller gets damaged. Loose wire connections in the digital control can also be a reason behind this problem. 


First off, remove the screws that hold the control panel in its place. Then, check the controller for loose wire connections. If there is loose wiring, tighten it up. Don’t forget to clean the controller with an air compressor to blow away dirt & debris. 

Now, put back the controller into the unit and turn on your Masterbuilt. If the controller doesn’t function, it gets defective. So, replace the controller with a new one. Call the Masterbuilt Support Team for a replacement. 

02. A Faulty Probe 

A defective sensor probe is the second culprit that causes your Masterbuilt smoker to keep shutting down. Due to a faulty probe, your electric smoker will detect the temperature incorrectly. Due to this smoker’s temperature issue, you smoker won’t stay lit or it keeps shutting off after now and then. 


To fix the probe issue, you should disassemble the unit. Use a Phillips head screwdriver to unscrew the nuts that hold the controller into place. Then, remove the plastic cover from the unit and pull out the controller. Now, locate the probe and ensure the wire connection of it is secured. 

Also, inspect the probe to see whether it gets damaged or not. If the probe gets defective, replace it with a new one. If the probe is intact, clean it gently to remove dirt & debris. Then, back everything into place and test the unit by connecting it with the electric outlet. 

03. A Blown Fuse 

If the fuse of your Masterbuilt smoker gets blown out, you can’t light the smoker or it keeps shutting off. The fuse of the smoker may get blown out for these reasons: 

  • You may plug your smoker into a tripped circuit breaker.
  • If the draft fan consumes a lot of power during the start-up phase, it will cause the fuse to get blown out. 
  • The fuse of your smoker gets old, or the auger uses more amps than normal. 
  • The igniter rod can also be the culprit behind this issue. 


No matter what causes the fuse to blow away, replacing the fuse is the only solution to fix this smoker issue. We recommend you call the Masterbuilt support team to replace the fuse for you. Or, you can call your local customer service to do this task for you. 


Does Masterbuilt smoker shut off automatically?

No, Masterbuilt Smoker doesn’t have an auto shut-off feature. But it will shut off automatically after the end of the heating duration you set. In simple words, set how long you want to cook and the smoke will turn off after that period. 

Why does my electric smoker stop smoking?

Your Masterbuilt Electric Smoker will stop smoking if the chip tray of this smoker will rise off of the burner element. To fix this issue, adjust the chip tray. 

Why is my Masterbuilt smoker not getting hot enough?

If the heating element on your Masterbuilt smoker gets defective, your smoker won’t produce enough heat you need. Just replace the heating element to let your smoker generate sufficient heat for cooking. 

Why is my smoker not holding heat?

If the fire doesn’t get enough oxygen, your smoker will not hold the heat. So, keep all the vents open to allow your smoker to draw more air into it. 

How often should I add chips to my electric smoker?

A cup of wood chips will last for 4-5 hours. So, you should add chips to your electric smoker after this period. 


It’s really a pain in the neck if the Masterbuilt smoker keeps shutting off in the middle of the cook. We broke down the reasons that cause your smoker to shut off continuously. So, follow the troubleshooting steps we mentioned to fix this smoker issue. Otherwise, you should call the Masterbuilt support team if you fail to solve the smoker problem.
