Masterbuilt 800 Issues

Masterbuilt 800 Issues

1. Temperature Problems

Temperature problems with the Masterbuilt 800 can be caused by a number of issues, including improperly calibrated thermometers, or blockage in the airflow.

It’s important to check if the thermometer is properly reading the temperature inside the smoker. This can usually be done by comparing it to an external thermometer, such as a cooking thermometer. 

Secondly, if there is a blockage in the airflow, it can be difficult to maintain consistent temperatures inside the smoker and result in lower temperatures than desired. 

Make sure to check all vents and openings for any blockage that could be restricting the airflow. Lastly, make sure to use high-quality charcoal with minimal ash, as this can also affect the temperature within the smoker.

2. Fan Issue

One of the most common issues reported with Masterbuilt 800 smokers is problems related to the fan. The fan is responsible for circulating air within the smoker, allowing for consistent temperatures throughout the cooking chamber. 

If it becomes faulty or dirty, it can cause fluctuations in temperature, leading to unevenly cooked food or even spoiling. Common symptoms include a noisy fan, an inadequate amount of smoke, and temperature instability.

Fortunately, most fan issues can be fixed with quick cleaning or replacement. To clean the fan, use a soft brush or cloth to remove any dirt buildup from the blades. 

If the motor has become faulty, you may need to replace it entirely with a new one. It’s important to check the fan periodically for any signs of wear and tear, as this can prevent further complications down the line.

3. Moisture Issues 

Moisture issues are a common problem for Masterbuilt 800 smoker owners. When the smoker is not properly ventilated, the internal temperature can become too low and result in moisture remaining inside the chamber. 

This trapped moisture can quickly lead to an overabundance of smoke, which will create an unpleasant taste in cooked foods. Additionally, excess moisture can cause food to become soggy and make it difficult for smoke to penetrate the interior of meats.

 To prevent this, be sure to properly adjust your Masterbuilt 800 smoker’s vents so that enough air is allowed in to help keep the chamber dry. 

More then, adding a water pan underneath the grates will also absorb any excess moisture that builds up. With the proper adjustments and techniques, you can be sure to avoid any moisture issues with your Masterbuilt 800 smoker.

4. Quality Control Issues

Quality Control Issues with Masterbuilt 800 smokers have been reported by users in recent years due to poor materials and build quality. In some cases, users have complained that the doors of the smoker don’t close properly, or the temperature control mechanisms are faulty.

Other issues include rusting of parts over time, warping or cracking of metal components, and poor insulation. 

To prevent these issues from occurring, it is recommended that users clean the smoker regularly, inspect all components for damage, and use high-quality BBQ covers when not in use. 

5. Poor Customer Service

Many people who have purchased Masterbuilt 800 Series smokers have experienced extremely poor customer service. 

Numerous customers have reported that they had trouble getting a response from the customer service team after submitting inquiries or complaints. 

Some customers were even told that their inquiries were being sent to the wrong department and were never answered. Others reported that they were given incorrect information and were not provided with adequate assistance. 

To make matters worse, many customers experienced long wait times when they attempted to contact customer service. These issues have led to a feeling of dissatisfaction among many consumers who bought Masterbuilt smokers. 

6. Wifi Issue

Masterbuilt 800 smokers with wifi capabilities can sometimes experience difficulty connecting to a WiFi network, making it difficult to monitor and control the smoker remotely. 

To troubleshoot this issue, check that your router is on and within range of the smoker. If not, make sure it’s placed close to the smoker and within a few feet of it.

More it, try restarting both the Masterbuilt 800 smoker and your wireless router. If these steps don’t work, you may need to reset the smoker to factory settings.

To do this, press the power button for 5 seconds and then release it. The smoker will automatically reset itself and should be ready to connect to your wireless network again. If these troubleshooting steps still don’t resolve the issue, you may need to contact customer service.

How long will a Masterbuilt 800 last?

This is mainly reliant on how often it is used and the type of environment it operates in; if the grill is not protected from extreme weather conditions or maintained properly, its lifespan could be shortened. 

Additionally, regular cleaning and replacement of parts can help to keep the grill running optimally for longer. Ultimately, the life span of a Masterbuilt 800 will depend on how well it’s taken care of throughout its lifetime.

 Make sure to check all these components of your smoker to ensure they are functioning correctly and reset as needed. If you still experience problems with your smoker after troubleshooting, contact customer service for further assistance.

Why is my Masterbuilt 800 not reaching temperature?

The most common reason why a Masterbuilt 800 may not reach temperature is due to an airflow blockage. 

Check that the air vents and exhaust ports are free of debris, lint, or other materials that could interfere with airflow. 

It is also possible that the thermometer probe may be malfunctioning, or needs recalibration if it reads inaccurately. If these measures do not solve the problem, contact your local service technician for further help.
