The 11 Most Common Mr. Heater Buddy Problems And Their Solutions

Let’s dive into the 11 different problems and their solutions for your Mr heater.

1. Keep Turning Off Your Heater

It can be very frustrating when your Mr. Heater Buddy keeps shutting off. Unfortunately, this event is a common problem with Mr. Heater’s products. But thankfully it can usually be fixed with a few simple steps. Here are some of the possible reasons why your heater might keep shutting off:

  • Clogged pilot: Over time, the pilot light can become clogged due to dust, dirt, or other debris. This can lead to the heater not getting enough fuel to stay lit and will cause it to shut off.
  • Inadequate fresh air to burn: If your heater isn’t getting enough fresh air to burn, then it will not stay lit and will shut off.
  • Tripped tip-over safety switch: This is an important safety feature that automatically shuts off the heater if it tips over.
  • Faulty regulator: If the regulator is faulty, then it can cause the heater to shut off.
  • Internal contamination: This can be caused by dust or debris getting into the system and clogging it up.

If your Mr. Heater Buddy is shutting off, there are a few easy fixes.

  • First, cleanse the pilot assembly to remove debris or dirt clogging the system.
  • Next, move the heater to a more open space, providing at least 9 square inches of opening to ensure enough combustible air.
  • Then, relight the heater when the tip-over safety device has been activated. Ensure the heater is placed on a flat, sturdy surface to prevent further malfunctions. If the regulator is faulty, replace it.
  • Finally, replace the control valve and regulator if there is any internal contamination.

2. Spark Lacking

If you need help to get your big Buddy to ignite, a lack of sparks from the spark electrode could be the culprit. The electrode may have become damaged and would need to be replaced. Also, ensure that the igniter wire is not connected to it and that the ground wire is not connected to the frame. This could prevent glimmers from occurring.

Mr. Heater Buddy Problems Spark Lacking

Follow the below solution to solve this issue:

If your heater keeps shutting off, it may be due to an Oxygen Depletion Sensor (ODS) malfunction. To fix this issue:

  • You will need to replace the ODS. Additionally, the spark electrode should be checked and replaced if it is not working correctly.
  • Ensure that the igniter wire is connected securely to the spark electrode, and the ground wire should be connected to the frame.
  • Also, check the igniter wire for any signs of damage or cracking. If the igniter wire is damaged, it should be replaced.

3. Heater’s Pilot Enable To Light

If the Mr. Buddy pilot doesn’t light up, there could be a few reasons:

  • No gas available for the heater: Make sure the propane tank has fuel and is connected properly to the heater.
  • Location of “PILOT” is not properly aligned: On the main control knob, make sure the position of the “PILOT” is in the proper spot to light the pilot.
  • Foreign objects obstruct the pilot: Look around the pilot’s area to see if any foreign objects, such as dust or cobwebs, are obstructing it from being lit.
  • Malfunctioning pilot, assembly: If none of these is the problem, then it is possible that the pilot assembly needs to be replaced.
Mr. Heater Buddy Problems Heater's Pilot Enable To Light

Here are some simple things to solve this issue:

  • The first thing you should do is check the fuel tank to ensure it has enough propane and is being supplied to the heater. If the tank is empty or low, use more fuel and try again.
  • Next, inspect the fuel hose for any clogs. If you find one, clean the hose with a cloth or compressed air can and reconnect it to the gas control module.
  • If the fuel is properly supplied, turn the gas control knob to the ‘PILOT’ position and press in. This should activate the pilot light.

4. Pilot Won’t Stay Lit

If your Mr. Heater Buddy’s pilot light is not staying lit, there are a few possible reasons:

  • The pilot wasn’t properly lit: The pilot flame must surround the thermocouple to keep it ignited.
  • Faulty pilot assembly: If the pilot tube or the burner is blocked, this can prevent gas flow and cause the pilot to extinguish when the control knob is released.
  • Bad wiring: If the wiring connection on the tip switch is disconnected, this can also cause the pilot to extinguish.
Mr. Heater Buddy Problems Pilot Won’t Stay Lit

If the control knob is not fully depressed and kept in the “PILOT” position, it will not allow the gas to flow. To ensure that it is in the correct position:

  • Press and hold the knob in place.
  • The thermocouple should also be positioned correctly to sense the heat coming from the pilot light. If it is not, it will not allow the gas valve to open.
  • Cleansing the pilot assembly can also help with any problems related to lighting. Check the trip switch wire to verify that they are connected properly.

5. The Igniting Pilot Flame Sensor Doesn’t Work

If your Mr. Heater Buddy is having trouble igniting, there are a few common causes.

  • The Clogged burner: This happens when debris builds up, preventing the gas from reaching the flame.
  • Insufficient gas supply: Make sure you have enough fuel in your tank; if you do, try switching it off and on again to reset the gas flow.
  • A faulty thermocouple: This device sends an electrical current to the ignitor, so if it’s not working correctly, the burner won’t ignite.

If a big buddy is having trouble staying lit, there are a few simple steps you can take to troubleshoot the issue.

  • First, check on the propane tank to ensure there is adequate fuel. If the tank runs low, fix it and try lighting the heater again.
  • If the fuel level is sufficient, move on to the next step.
  • Cleanse the burner orifice by removing the burner assembly from its housing,if there are dirt, dust, or spider webs, examine the inside of the burner for them.
  • Check the burner assembly, ensure that the main burner and the venturi tube are functioning properly, and if necessary, replace them.
  • Cleanse the propane heater exterior with a damp cloth to remove any dirt or debris that may have been collected on the exterior surface.
  • Finally, if all else fails, replace the thermocouple if the burner is still not light.

6. Delay In the Ignition Process

This issue occurs when the burner lights up later than it should. This can be dangerous as it can cause damage to the unit and potentially lead to an accident. The most common causes of delayed ignition include:

  • Low manifold pressure
  • A clogged burner orifice

Let’s take a look at the possible solution to this problem.

  • If your heater runs on natural gas, you should contact your local gas company for assistance.
  • If it runs on propane tanks, you should check the gas regulator to ensure it is in good working condition.
  • It would help if you also inspected the burner to ensure it is not clogged with debris.
  • If the orifice does need to be cleaned, use a brush or soft cloth and rub gently in a circular motion until all dirt and debris are removed.

7. Heater Backfiring

When using a Mr. Heater Buddy, backfiring can occur. Backfiring is an undesirable outcome often caused by a few different factors.

These include:

  • Clogged or damaged burner orifice: The burner orifice is the opening where fuel enters the combustion chamber. If this opening is blocked, the fuel cannot properly enter the combustion chamber and ignite, leading to backfiring.
  • Damaged burner: If the burner has been damaged somehow, it can cause backfiring due to insufficient fuel entering the combustion chamber.
  • Defective gas regulator: The gas regulator regulates fuel flow into the combustion chamber. If it is defective, it can lead to insufficient fuel entering the combustion chamber, which leads to backfiring.

To solve the issue:

  • Clean up the burner orifice.
  • If this does not resolve the issue, it is important to inspect the burner for damage and replace it if necessary.
  • In some cases, the gas regulator or flame sensor may also need to be replaced.

8. Buddy Heater, Smells Like Gas

If you notice a strong smell of gas coming from your Mr. Heater Buddy, it could cause concern. There are several possible reasons for the odor, and it is important to identify and fix the issue quickly.

Possible factors for the smell include a gas leak, compressed air, debris between the control valve and burner, or a defective valve.

Pressure testing the gas connections of a heater is necessary to rule out the possibility of a gas leak. To do this, follow these steps:

  • Confirm that the heater supply piping system is connected and that it has been leak-tested.
  • Turn on the equipment’s shutdown valve and the propane or LP supply valve.
  • Inspect all connections between the equipment shutoff and control valves. Cleanse gas joints with a mixture of liquid soap and water.
  • Repair all leaks at the same time.

9. Your Heater’s Control Knob Is Not Able To Turn

If your Mr. Heater knob seems stuck in one position or isn’t turning in both directions, it is a sign of a malfunctioning heater.


If you find that the control knob on your Mr. Heater Buddy cannot turn, you can take a few steps to solve the problem.

  • First, use a flathead screwdriver to pry off the control knob.
  • Once the knob is removed, apply some silicone lubricant or WD40 to the control knob stem.
  • Make sure to spread the lubricant as much as possible, then replace the knob.
  • Turn it in all directions to ensure it operates smoothly.
  • If the problem persists, you may need to replace the knob.

10. Loud Noise From the Heater

It’s common for this heater to make noise, whether a whistling or a buzzing sound. Suppose you are experiencing a whistling noise when the burner is lit. In that case, it may be caused by the control knob being in the position when the burner is cold, air passageways on the heater, or the pilot tube being blocked.

Mr. Heater Buddy Problems Loud Noise
  • Turn the control knob to the LO position and let the burner warm up before turning it to the HI position.
  • If air is in the gas line, keep the burners running until all the air is released.
  • The heater should be placed in the coldest section of the room, with proper ventilation, and where it can be easily accessed for operation, inspection, and service.
  • Cleanse or replace the burner orifice if the issue persists.

11. Heater Not Getting Enough Fuel Through Control Valve

If your Mr. Heater’s Buddy is not getting enough fuel supply, it could be due to a loose hose attachment or screw-on valve.


The solution to these common Mr. Heater Buddy problems is to examine the hose connection to the gas cylinder.

  • You should ensure that it is firmly tightened against the release mechanism of the propane tank, as some tanks contain safety mechanisms that prevent gas from escaping unless the hose connection is sufficiently tight.
  • In addition, the screw-on valve should also be tightened if it has become loose.

A Step By Step Method To Set Up Mr. Heater Buddy With Propane Tank

Setting up Mr. Heater Buddy is easy and requires no additional tools or expertise. All you need to do is:

  • Attach the portable propane tank to the heater.
  • If you’re using a 20-pound tank, ensure the propane hose is securely connected and there are no leaks.
