However, if you’re experiencing an issue where the fan is not working, it can disrupt your smoking process and temperature control. 

In this article I will explore the possible causes and solutions for this issue, helping you troubleshoot and fix the problem efficiently..

By following the troubleshooting steps outlined you will be able to identify the root cause of the fan problem and potentially resolve it yourself, saving time and money.

Common Causes Of Masterbuilt 800 Fan Malfunction

One of the common reasons for the Masterbuilt 800 fan not working is a faulty power supply. Ensure that the power cord is properly plugged in and the outlet is functioning correctly.

Another possible issue could be with the internal wiring of the smoker. Damaged or loose wiring connections can disrupt the fan’s operation. It is important to carefully examine the wiring and fix any issues accordingly.

If the internal wiring seems fine, the problem may lie with the fan motor itself. A defective fan motor can prevent the fan from spinning properly, leading to a malfunction. In such cases, replacing the faulty fan motor is necessary.

Regular maintenance and inspection of the power supply, internal wiring, and fan motor can help in preventing or quickly resolving these common causes of Masterbuilt 800 fan malfunctions.

Checking The Power Supply

Verify power outlet: Start by making sure that the power outlet you’re using is working properly. Plug in a different appliance or device to confirm that electricity is flowing to the outlet.

Inspect power cord: Check the power cord of your Masterbuilt 800 to see if any damage or fraying is present. If you notice any issues, it may be necessary to replace the cord.

Test power source: If the power cord appears to be in good condition, try plugging the smoker into a different power source. This can help determine if the problem lies with the original power outlet or the smoker itself.

Inspecting Internal Wiring

Start by disconnecting the power supply to the smoker to avoid any electrical accidents. Once this is done, accessing the internal components becomes possible.

  • Now, Carefully remove the back panel to gain access to the wiring.
  • Inspect the wiring connections to identify any loose or damaged wires. 
  • Reconnecting any loose connections and replacing any damaged wiring is recommended.
  • Testing the wiring connections is the next step to ensure proper functionality.
  • Use a multimeter to check for continuity and proper voltage flow.
  • If any defects are identified, take the necessary steps to repair or replace the wiring as required.

By diligently inspecting the internal wiring and performing necessary tests, potential issues with the Masterbuilt 800 fan can be addressed and rectified effectively.

Replacing The Fan Motor

Replacing the faulty fan motor in your Masterbuilt 800 smoker is a straightforward process that you can do at home. Here’s a step-by-step guide:

Obtaining replacement fan motor

To start, you’ll need a new fan motor for your Masterbuilt 800 smoker. Visit a local appliance store or check online retailers to find the appropriate model that fits your smoker’s specifications.

Removing the old fan motor

Before beginning any work, make sure to disconnect the smoker from the power source. Once that’s done, locate the old fan motor, usually positioned at the back of the smoker.

Unscrew any screws or bolts holding the motor in place and carefully detach the wiring connected to it. Remove the motor from the smoker.

Installing the new fan motor

Take the new fan motor and align it properly in the designated spot. Reattach the wiring, ensuring a secure connection. Use the screws or bolts to fix the motor in place. Double-check all connections to ensure they are tight and secure.

That’s it! With the new fan motor in place, you can now reconnect the smoker to the power source and resume your smoking adventures.

Seeking Professional Help

When troubleshooting electrical appliances, it’s essential to reach out for professional assistance.

Firstly, contacting the Masterbuilt customer service is a recommended step. Their expert representatives can provide guidance on addressing the fan malfunction. They may suggest potential solutions or advise on the need for repair or replacement.

If the problem persists, consulting a professional technician is the next logical step. They possess the knowledge and experience to diagnose the specific issue with your Masterbuilt 800 fan.

Preventive Maintenance To Avoid Fan Issues

Cleaning the fan regularly is essential to keep your Masterbuilt 800 smoker functioning properly.

Gradual buildup of dust and debris can hinder the fan’s performance, leading to issues like it not working at all.

To clean the fan, make sure to unplug the smoker from the power source and remove any food or trays inside.

Use a soft cloth or brush to gently wipe away any dirt or residue on the fan blades and surrounding areas.

Keeping the smoker protected from weather elements is also crucial to prevent fan problems. Make sure to cover it when not in use or store it in a dry place.

Additionally, employing proper storage techniques can significantly prolong the lifespan of the fan. Avoid exposing it to extreme temperatures and humidity, as these factors can damage the electrical components.

By implementing these preventive measures, you can minimize the chances of fan-related issues with your Masterbuilt 800 smoker.

How often should I clean the fan?

Regular cleaning is recommended, ideally after every few uses or when performance decreases.

Can I replace the fan motor myself?

Yes, but refer to the manufacturer’s instructions or seek professional help for proper installation.


Troubleshooting a masterbuilt 800 fan not working can be a frustrating task. However, by following the steps I have mentioned in this blog post, you can easily identify and resolve the issue. Ensuring proper power supply, checking for obstructions, and contacting customer support if necessary are some effective solutions.
