Little buddy’s sensor

Every little heater buddy you purchase comes forth with an installed sensor that poses to be your safeguard and prevents you from being in a life-threatening situation. The heater’s sensor detects a possible risk or hazard, cuts down the fuel supply, and extinguishes the flame. 

Therefore, you must not find it exasperating that your little buddy is not lighting up because it is doing so to maintain your safety. However, after you have observed the heater’s flame and concluded that it is not too huge or too small, consider cleaning the heater’s sensor. 

Cleaning the sensor is a very straightforward process as you only need sandpaper to scrap off any carbon or soot build-up on the device in excess. Next, try again with a flame that covers half of your sensor. Even after this, you can still not remedy the situation with our provided solution, then resort to replacing the old sensor with a new one. 

Pilot tube build-up

A pilot tube is, in fact, a very narrow tube that is in your buddy heater and is attached from the main burner to your flame, trying to light it up and provide warmth. 

As the tube is very sleek in its composition and by the nature of the job it fulfills, this will be no surprise to find out that there has been a build-up in the pipe. To confirm your suspicion and prevent your buddy heater from lighting up, take a closer look at the pipe from the tiny viewing window at the top of your control knob. 

An alternate way to confirm your suspicion about the pilot tube is to notice your flame. If the pet is lit bright blue, then there is no problem with the pilot tube; however, if the flame is unsteady and in the shade of yellow, the tube calls for a dense clean! 

To clean the tube, first, switch off any valve on the heater that provides gas to the main burner as a safety precaution. Then using a cleaning drier, blow it towards the tube to rush out any dirt from within it.

You can also take up the cleaning process with a sharp, thin, and long needle to rake off soil from the inside of it.

Supposedly, if you have cleaned the pilot tube and your Mr heater little buddy is still not lighting up, you might get a new one! 

The gas flow valve is clogged.

Situated beside the pilot light, you will come across a valve, small in size, responsible for controlling the gas pressure supplied. The valve must be set accurately according to the fuel you choose to utilize to power your little buddy heater. 

Similar to all the other components, this small gas flow valve can sometimes be clogged too and requires a thorough cleansing. To do this, you must first disconnect the valve from its connection to ensure that no fuel is being supplied, and then using your preferred tool: an air compressor or a thin pin, clean this valve too to avoid a clog. 

Blocked thermocouple

The thermocouple on a buddy heater is another safety device that looks out for a flame and senses if there is a flame or not in the heater. This part of the heater can sometimes get blocked due to the build-up of carbon or soot and would need cleaning.

To clean the thermocouple, use sandpaper to gently and cautiously dispose of any impurities. This will reconcile the situation and light up your heater effortlessly. 

A weary thermocouple

When you make extensive and consistent use of your little buddy heater, at times, the thermocouple of it seems to be worn out. It will then be unable to distinguish the flame on your heater and consequently cut out from the pilot as a necessary safety measure that has to be tackled to prevent a gas leak. 

Fortunately, the worn-out thermocouple is a convenient and quick fix to restore your state of affairs. Shut down the buddy heater and wait for it to cool down so that you may not burn your skin while checking for the problem. Then move the thermocouple closer to the pivot and near the flame, which is in its original position. Try your luck at lighting the buddy heater up. 

Therefore, if the buddy heater still goes without light, we advise you to immediately replace its thermocouple with a new one. 

Unsuitable draft positioning

Draft positioning is a vital element in ensuring the buddy heater works properly. This is because it is in charge of supplying adequate airflow to the entire heater system and works with the air’s help. However, the airflow should be modest: it should not be too much or too little, as an abundant flow of air can cause the fire to blow out.

If the draft is not fixed correctly, it would mean that the air will not circulate through the heater and will not spark a flame. Therefore, to counter this problem effectively, follow these: 

  • Alter the airflow to a medium amount
  • Avoid placing your heater in a surrounding that has a massive airflow 
  • Shield the air draft of the heater through a barrier
