Pit Boss Grill Not Heating Up? Here’s Why (and How to Fix)

Check the Current Weather at Your Place

Weather is one of the most common causes of temperature issues on Pit Boss Grill. Wind, direct sunlight, rain, humidity, hot weather, or cold weather can affect your Pit Boss Grill temperature and cause abnormal fluctuations. This means that weather conditions can hinder your grill from getting hot.

How to Fix

  1. First of all, check the current weather in your place.
  2. Avoid keeping your grill outdoors during any of the weather conditions we’ve mentioned above.
  3. Ensure you cover your Pit Boss Grill to protect it from harsh weather. Consider covering your grill using Cloakman Premium Heavy-Duty Cover for maximum protection.

Adjust Your “P” Settings

The “P” setting represents PAUSE. When you increase the “P” settings, the pause time between pellet cycles will also increase. By doing so, you’ll be withholding the pellets for an extended amount of time, which will result in a lower temperature and additional smoke.

Adjusting the “P” setting too frequently or too far does cause further temperature issues in your Pit Boss Grill, including massive temp swings and flame dying out. When this happens, then your Pit Boss Grill won’t get hot.

How to Fix

  1. Only use “P” settings on the “SMOKE” mode.
  2. Adjust your “P’ settings in intervals giving them about 30 minutes to settle
  3. If your grill is losing its flame or dropping temperature, don’t increase the “P” setting but instead decrease it.
  4. Use your Pit Boss Grill at a factory setting of P-4 before adjusting the “P” settings.

The following video will help you understand the “P” setting and temperature on your Pit Boss Grill control panel:

Keep Your Burn Pot Free of Corrosion

If your Pit Boss Grill burn pot has holes, then it’s easy for heat to escape causing your grill not to get hot. This typically happens to older Pit Boss Grills. However, depending on how you keep your grill, the burn pot can corrode and get some pinholes, which will let the heat out, causing your grill not to heat up.

How to Fix

  1. Replace your burn pot. When replacing it, consider using the QuliMetal Fire Burn Pot for maximum efficiency.
  2. If the corrosion is severe, consider purchasing a new Pit Boss Grill. 

Check the LCD Screen

When the LCD screen on your Pit Boss Grill isn’t lighting up, your grill won’t get hot. There are four causes of LCD screen not lighting up which include:

How to Fix

  1. Ensure your Pit Boss Grill is plugged in correctly into an effective power source.
  2. Ensure all electrical cable connections are connected firmly.
  3. Check the fuse for a damaged wire. Also, check if the fuse cables have turned black and, if so, replace it.
  4. Ensure your GFCI is between 10 to 15 amp service.
  5. Avoid using your grill over 25 feet.
  6. Turn your temperature dial to “SMOKE” mode to start-up the grill.

Ensure the Igniter Is Working

Pit Boss Grill not igniting is also a common reason behind its heating up failure. The ignition problem is typically caused by ash build-up, old pellets, low-quality pellets, wet pellets, or a defective igniter. 

How to Fix

  1. Blow/clean out the ashes after every cook.
  2. Replace any charred black pellets in your firepot.
  3. Ensure you don’t place wet pellets in your firepot.
  4. Use premium quality pellets to avoid ignition difficulties. Consider purchasing the Pit Boss BBQ Wood Pellets for hotter and cleaner burning.
  5. Clean the igniter or replace it if it’s damaged. The QuliMetal Grill Hot Rod Ignitor will serve you better.

Check if the Combustion Fan Is Working

This is a common Pit Boss Grill heating problem that usually occurs after several years of use. Combustion fan issues start to occur due to a lack of regular grill maintenance. Grease builds upon the fan restricting its movement. 

The combustion fan’s primary role is to pull enough air into the firepot to feed the fire and blow the smoke out through the chimney. If this fan fails, the heating efficiency of your Pit Boss Grill will be minimal. 

How to Fix

  1. Clean your combustion fan.
  2. Turn off everything and try rotating the fan manually using your finger or a screwdriver.
  3. If the fan is damaged beyond repair, consider replacing it. The Stanbroil Induction Fan Kit is recommendable for replacements.

The following video demonstrates how to replace a combustion fan in your Pit Boss Grill:

Try Manual Ignition

Sometimes you can start-up your Pit Boss automatically but fail to heat up due to mechanical igniter problems, as we mentioned above. 

How to Fix

  1. Turn the temperature dial to off position.
  2. Plug in your power cord into a 110V grounded outlet.
  3. Ensure there are no foreign objects in the auger feed or hopper system.
  4. Fill the hopper with dry pellets.
  5. Remove the flame broiler, cooking grids to expose the firepot.
  6. Squirt any approved pellet starter or add a small little solid fuel fire starter.
  7. Add a small number of dry pellets over the fire starter.
  8. Use a lighter or long fireplace match to light the starter and burn for about 5 minutes. You can use the Foxfires Butane Long Lighter to do this. 
  9. Replace the cooking grids and flame broiler quickly but carefully.
  10. Turn your temperature to SMOKE.
  11. Turn on the temperature dial and allow your Pit Boss Grill to heat for about 10 to 20 minutes.

Clean Your Pit Boss

Dirt, ash, and debris in an unclean Pit Boss Grill can cause auger jams, flameouts, and igniter problems. If it has been long since you cleaned your grill, then there’s a build-up of dirt, ash, and debris preventing the heat from reaching the pellets.

How to Fix

  1. Use a Spark Quick Grill Brush to scrub the surfaces of your grates.
  2. Use a shop vac to blow out any ash.
  3. Remove your flame broiler and wipe off the gunk that hasn’t dripped into the grease bucket.
  4. Empty the grease bucket.
  5. Use Pit Boss Grill cleaner and decreaser to remove any burnt grease or stubborn debris.
