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.


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. 

Masterbuilt is very good at fixing up issues even when your warranty is up. Their service is definitely top-notch.

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.

If the issue is caused by a grease fire, try throwing in some baking soda to smother the fire. Baking soda will release carbon dioxide and the fire will be extinguished. 

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.

It could be your switch that needs a replacement. After you’ve fixed the issue, turn the grill back on. Your smoker is good to go again.

  1. I have only used my Master built smoker twice and started getting error code 2. It has been a year and I have tried to call and contact Massterbuilt by email. They never contact me back. I have a $300.00 paperweight in my garage. Horrible product and horrible customer service.

    • It means it’s too hot or cold. Unplug it, plug it back in re-enter your values. Too hot can be too much charcoal or no water. Too cold fire went out or you need more charcoal. It’s really annoying and there is no alarm silence.

  2. Master built has the worst customer service!!!!!!!! EVER!!!! you can only contact them by email… and if they do respond. they still tell you to try the same dam thing!!!! I have been trying too get my smoker going for over a month. like you said 300 dollar paper weight. I have several PIT BOSS products. and the CUSTOMER SERVICE is ABSOLUTLY EXCELLENT!!!!!

    • Interesting. I haven’t had any problem with Masterbuilt customer service. On the other hand Pit Boss cust service is absolutely unresponsive.

  3. POS
    I’ve been dealing with warranty customer service for since May 2022 due to LEAKING GREASE ALL OVER THE PATIO! unacceptable.
    first replaced bottom tray. Still leaked. second, replaced the body which entailed complete disassembly and reassembly. Got it put back together and now it doesn’t work at all.
    try to adjust temp and it errors with “560” then “V002” then “R001” I have no idea what those are. Submitted another warranty claim. what a piece of junk.
