Masterbuilt Smoker Error Code 2

If your smoker is displaying this error code, it means the meat probe is malfunctioning.

The most probable reason is the connectors to the heating element disintegrated. Without fixing the meat probe, this error code can’t be removed.

Solution:

Here’s how you fix this issue:

• Look at the back panel of your smoker. There are 6 screws and a thin rubber gasket that can be peeled off. You’ll find two insulated wires. 
• If they look charred and some pieces crumble away when touched, this is the problem.
• Clean off the paddle to the heating element with a small wire brush.
• Crimple on new paddle connectors and slip on some shrink wrap that will cover the wires and extend down past the end of the paddle to cover the heating element contacts. 
• Heat the shrink-wrap with a mini-torch. Insulate and weatherproof the connections that way. 

If there’s nothing wrong with your wire connections, then we recommend you contact customer service to find out what the issue is.

Solution:

Follow these instructions to get rid of Err 3 and get your smoker running ASAP-

Turn off the grill. Investigate the cause of overheating. Usually, it is caused by grease fire and smoker fan malfunction.

You can also try spreading salt on your grill. Salt will absorb the heat. Then clean the smoker perfectly to make it for your next cook. Here you can learn how to clean a smoker after grease fire like a pro.

As for the fan not working, you could get an aftermarket fan to replace it. The problem may also be in the switch. Check the switch for signs of melting.
