Masterbuilt Smoker Not Heating? – Causes

There are many reasons why your smoker isn’t heating up.

Explore some of the most common causes of a non-heating Masterbuilt smoker below.

Did You Start It?

Though seemingly obvious, your Masterbuilt smoker may be new, and you don’t know how to start it.

So, ensure you turn the right knobs or press it correctly before checking other defects that may prevent your Masterbuilt smoker from heating.

No Power or Gas Supply

We tend to forget to turn on most electrical appliances before using them.

Alternatively, you may think you left it on to grab something, yet you turned it off.

So, confirm that your socket is on.

If it’s on, establish whether there is a power connection.

Try turning on your stereo, TV, or light.

The heating issue may be as simple as the absence of an electrical supply.

If you lack electricity, check to see if there are any blown fuses or tripped breakers in your electrical panel.

Any of these scenarios cuts off power preventing you from using any electrical appliances.

If there’s electricity, then the problem may be a faulty outlet.

You may have your smoker on a socket that has no power.

Check if your LPG gas tank is empty if using a Masterbuilt propane smoker.

Confirm that the connector hose has a secure connection.

Power Cord Issues

The second most straightforward answer to a Masterbuilt smoker, not heating, is an unplugged power cord if your socket is on.

Check the power cord to ensure you inserted it correctly into the socket.

If it is, then the problem could be a breakage.

Inspect the entire power cord, particularly at the point it connects to your Masterbuilt smoker.

Do you see any chipping, cuts, or loose wires?

If so, your Materbuilt smoker isn’t receiving power hence won’t heat.

Besides checking the smoker’s power cord, confirm that your extension has a proper connection to the socket if you are using one.

Faulty Heating Element

Sometimes, the problem lies with a faulty heating element.

Check whether the element has burns or is partially melted.

Short-circuiting is a common problem with electric smokers.

Some instances are pretty severe, leading to wire disconnection.

Open the rivets on your smoker’s back.

Inspect the insulation around the box, wires, connectors, and back cover for any burn signs. Moreover, look at the wires for disconnection and burns.


Other times, corrosion of wires linking to the heating element may be the issue.

If you conduct poor maintenance practices, some connectors may corrode within a few months, rendering your Masterbuilt smoker dysfunctional.

Corrosion gradually eats away the connector, loosening the wire in the process.

 Loose/dirty chip tray

If your Masterbuilt Smoker not heating up then sometimes the chip tray is the culprit.

The chip tray may get loose.

If the chip tray comes loose from the burner element, it doesn’t allow sufficient heat to get to the wood chips.

Sometimes chip tray is dirty or unclean because of which your Masterbuilt smoker not getting hot enough.

This ultimately causes not heating your Masterbuilt smoker.

So, don’t forget to check the chip tray if this issue occurs.

Waterpan  may be the culprit

Actually, Masterbuilt electric smokers don’t attain much temperature.

The average temperature range of a Masterbuilt smoker is 210-250 degrees Fahrenheit.

So, if your Masterbuilt electric smoker isn’t reaching 150 or 200 degrees Fahrenheit, then there is an issue with your smoker.

And this problem may be due to your water pan.

Every Masterbuilt electric smoker comes up with a water chamber and pan.

Using the water pan is great for smoking but sometimes it may lead to heating issues.

Bad temperature controller

If your Masterbuilt smoker not heating up, then you should check the controller. Check your controller whether it is working properly or not.

If your temperature controller is bad, your smoker can’t reach the desired temperature or not show the right temperature.

So, if your Masterbuilt smoker not heating up checking the controller is the essential step.

Intake vents are not open adequately

One of the most common reasons for not heating the Masterbuilt smoker is that your smoker is not getting enough oxygen.

If the intake vents are not open enough, it will be difficult for your smoker to get enough oxygen.

Due to improper air flow, your smoker won’t heat up fast or at all.

Fried spade terminals/connectors

The Masterbuilt smoker won’t heat up due to the bad spade terminals or fried connectors.

The spade terminals sometimes burnt up and disintegrated.

You have to check the terminals whether they are in good condition or fried for solving this issue.
