1. Excessive AMP Load

In simple words, the Pit Boss fuse blows when the supply of electricity is more than needed. An overflow of electricity can come from the power supply board on its own.

Even if all the components are working fine, this type of situation can arise. Though this is very unlikely to happen, it’s a possibility. 

How To Prevent It:

Preventing this type of problem is very simple. Just have a look at the main power supply system of your house. Call up an expert to examine the problems. If they detect any misconduct going on, then that’s the thing you have to take care of.

Although, you should know that it’s a risky task. So it’s better to leave this part of the problem to the professionals. Paying the electrician only a few extra bucks will save you from unnecessary difficulties.

2. Draft Fan Issue

The draft fan is one of the major components of the Pit Boss grill. This part of the unit is directly connected to the fuse with a yellow wire.

The draft fan is supposed to consume 120V, 0.1 AMP power at 50/60 Hz. The fuse blows if the draft fan pulls more than this amount of electrical power. This usually happens at the startup.

How To Prevent It:

If you discover that the fan is the culprit ( how to know which part is the culprit? You will find more on this in the next part of the article), then replace it. Here’s how to replace the Pit Boss grill draft fan:

  • Locate the draft fan under the auger
  • Disconnect all the wire-connection for the auger fan
  • Remove the 4 screws holding the auger fan
  • Disconnect the Molex connector before removing the fan
  • Take a new draft fan and put it in the position of the draft fan
  • Attach all the wires before screwing the fan in its place

Once you have installed the draft fan perfectly, you won’t have to worry about your Pit Boss grill fuse again.

3. Blown Circuit Breaker

Your house’s central circuit breaker can blow up and result in a power outage. However, a tripped circuit breaker can still leave power in a particular part of your house. The areas where the circuit remains unaffected generate too much electricity.

If your Pit Boss smoker is in one of such areas, the fuse of the circuit board will definitely blow up due to too much flow of current.

How To Prevent It:

Resetting the circuit breaker will prevent your Pit Boss fuse from blowing up again. Here’s how to reset it:

  • Locate the gray metal box of your circuit breaker. If you don’t know where it is in the house, ask your landlord
  • Open the side panel of the gray box and locate the tripped breaker
  • Look closely to find the breaker that has shifted from the ON position. That’s the tripped breaker
  • Once you have identified the faulty circuit breaker, turn off all the electrical appliances in your house
  • Now push the tripped breaker to the ON position

After this, your house will have an ideal supply of electricity. This saves your Pit Boss fuse from blowing up as well.

4. Faulty Ignitor

Just like the draft fan, the ignitor is another major component of the Pit Boss grill. It consumes 200W, 2.6 AMPs, and 120V of electricity.

If the ignitor is faulty for some reason, it will demand more electricity and blow up the fuse in the process. 

How To Prevent It:

You should replace a faulty ignitor right before you replace the Pit Boss fuse. Here’s how to change the Pit Boss ignitor:

  • Remove the frames and grates in the smoker grill
  • Use a Phillips screwdriver to remove the screws on the firepot
  • Once you have access to the ignitor, unscrew it from its place
  • After unscrewing, pull out the ignitor through the burn-tube hole
  • Disassemble the bottom plate from the bottom of the pellet hopper
  • Detach all the wirings and remove the faulty ignitor from its place
  • Take a new Pit Boss ignitor
  • Reverse this process to install the new ignitor
  • Put everything back to where they were

Now you can rest assured that your Pit Boss fuse won’t blow up again due to a faulty ignitor.

5. Defective Auger Motor

The Auger motor takes 120V, 0.22 AMP of electricity at 50/60 Hz. This part of the unit is directly connected to the fuse through a red wire.

So if this auger motor is faulty, it will consume excessive power through the fuse. As a result, the fuse will blow up.

How To Prevent It:

Replace the faulty auger motor before replacing the fuse. Here’s how to do it,

  • Locate the auger at the backside of the Pit Boss grill
  • Unscrew the bolts holding the motor there
  • Detach the wires connected to the auger motor
  • Pull out the auger motor
  • Set a new auger motor in its place
  • Reinstall all the wiring
  • Screw up the bolts the way it was before

Now your Pit Boss auger motor won’t take excessive electricity. Hence, there won’t be a blown fuse. And with this, the list of reasons ends. There are usually no causes behind Pit Boss blown fuse other than these.

How To Identify The Culprits Behind Pit Boss Fuse Blowing

You can easily identify what’s causing the fuse blow-up in your Pit Boss grill using a multimeter. It will help you to fix the issue quickly. Here’s how to do it:

Step 1: Get A Multimeter

You need to use a multimeter to detect the part causing the fuse to blow up. The multimeter tells the amount of voltage a wire conveys to its designated part.

Once you find out the voltage rate, you can determine which component is the reason behind blowing up your Pit Boss fuse.

Step 2: Using The Multimeter

Firstly, turn off the whole unit. Then set the dial on the multimeter to V. Now you have to use the multimeter for each wire. There are 3 cables in total: black, purple, and red.

Touching the multimeter’s red probe to these wires will show the amount of voltage each wire conveys. Here’s what each wire directs:

Device Wire
Auger MotorRed
Draft FanYellow

Step 3: Checking The Results

Now you have to note down the voltage rate of these wires. If any wires show a rate higher than 120V, you can declare that its designated part is faulty.

For example, if the red wire shows more than 120 V on the multimeter, you can conclude that the auger motor is the reason your Pit Boss grill keeps blowing the fuse. The same goes for the other two wires.

You can watch the tutorial to know how to use the multimeter to check the voltage.

Once you have identified the culprit, make sure to change or fix it before replacing the fuse with a new one.

  1. I’ve never even used my unit but I plugged in and no power. I just replaced the fuse and plugged in and heard the new fuse pop. When you state you must know how it goes in?
    Is there a positive/negative side? I’m not sure what your mean about knowing the position, it only goes in one way

  2. Hi
    My Ignitor on my Pit Boss Navigator failed. When I replaced it all started up ok, then a flash of sparks and all shut down. The ignitor blow the fuse and the plug fuse as well ,I replaced the ignitor and the same again happened. When you look at the ignitor you can see half way up the stem its blown a hole in the side.
    Has anyone got a idea what could be causing this.
