Mr Heater Portable Buddy Pilot Won’t Light

If your pilot light is out, generally not a big deal. Turn the gas off, light it again and it typically relights. But then sometimes you get that rare moment where it just wouldn’t relight. It must be something unusual… oh no! You’re at the beach, on vacation, and now you are stuck with no heat in your home because Mr heater’s portable buddy pilot won’t light. There are a few things you can check and fix in order to make it work again. We will examine them in this article.

How to Fix a Mr. Heater Portable Buddy Pilot Light That Won’t Work

1. Check the fuel level

Check the fuel level. If this is low, it can prevent the pilot light from igniting.

Make sure that you have enough fuel in your tank before trying to relight the pilot light again. The pilot light will not ignite if there is no or very little gas in your tank (which could mean that your heater has been turned off for an extended period).

2. Make sure there is no air in the fuel line

If you have recently run out of propane, there may be air in the fuel line. Using the heater several times in succession should push out any residual air and get your heater running again.

If your pilot light refuses to stay lit, it may be because there is some internal problem with your heater and it needs to be repaired or replaced. You can try calling a local heating repair service or visit a hardware store to see if they have any good deals on heater parts that are similar to yours.

3. Make sure that the heater’s flame sensor is clean and unobstructed by dirt or other grime

To check the flame sensor, remove the heater’s protective housing and then reinsert it. If you find any blockages or dirt in the burner tube that connects to your gas line, remove this blockage with a damp cloth and try to light the pilot light again.

If your pilot light won’t ignite after cleaning out your flame sensor and reinstalling it, you may need a replacement part.

4. Make sure that there are no obstructions in the vent or exhaust area

Make sure that there are no obstructions in the vent or exhaust area of your Mr Heater portable buddy, as this can also prevent the pilot light from igniting properly.

Make sure that the pilot light is in the center of the burner. If it’s not centered, then adjust it by rotating it slightly counter-clockwise until it goes out and ignites again when you turn on your heater again (this will help you understand which way to turn it).

Check to see if there are any obstructions around or in front of where your Mr Heater portable buddy sits, as these can also block airflow inside your heater and prevent the ignition from occurring correctly.

5. Check the regulator and make sure it is not frozen up

If you have been using your Mr. Heater portable buddy in a very cold environment, then the regulator may be frozen up or damaged, preventing it from delivering and maintaining sufficient gas flow for lighting your pilot light properly. You’ll need to replace a damaged regulator to get your Mr. Heater working again properly.

The regulator is a key component of the Mr. Heater portable buddy. It’s responsible for maintaining sufficient gas flow for lighting your pilot light properly, so if your regulator is damaged or malfunctioning, it won’t be able to deliver sufficient gas flow. To fix this problem, you’ll need to replace your damaged regulator with a new one.

How Do You Clean the Pilot Light on a Mr. Buddy Heater?

  • Make sure the heater is turned off. If it is not, turn it off and wait until it has cooled down before proceeding.
  • Unscrew the pilot light cover. The location of this may vary depending on your particular model of Mr. Buddy heater, but they all feature some sort of protective cap that can be removed by turning it counterclockwise with your hand or using an adjustable wrench if necessary.
  • Clean the pilot light with a cotton swab and alcohol (optional). The purpose of this step is to remove any soot or other gunk build-up in order for it to function correctly again but if there isn’t any visible buildup on your particular unit’s pilot light assembly, you can skip this step entirely!

However, if you’d like to give yours a quick cleaning anyway just in case…

Take an old cotton swab dipped into some rubbing alcohol (or simply use plain rubbing alcohol from an eyedropper) and gently rub along both sides where air enters and exits through tiny holes located inside each end cap for about 30 seconds at most.

Why Does the Pilot Light Go Out on My Mr. Heater?

If your sensor is dirty or damaged, it can cause the pilot light to go out. You may also experience this problem if there is no gas flow or if the thermocouple clog is damaged.

If you have a clogged-up thermocouple, it will not be able to detect inlet air temperature and therefore not be able to adjust accordingly. This means that the heater will operate at a lower capacity than necessary, which could damage the appliance itself over time.

How Do You Manually Light a Mr. Heater?

To light your Mr. Heater Pilot, follow these steps:

  • Turn the knob on the heater to the “pilot” setting and then remove it from its base.
  • Light a match or lighter and hold it under the gas supply tube until you see ignition at the top of the tube (this may take several seconds).
  • Replace the pilot assembly back into its base and turn it to “on” once more. If your appliance has an automatic shutoff feature, this should automatically be disabled after lighting and you can use your portable buddy immediately.

How Do You Light a Mr. Heater Buddy With a Propane Tank?

To get your Mr. Heater Buddy portable heater running, follow these steps:

  • Remove the propane tank from the heater and turn it upside down to drain out any remaining gas.
  • Turn the valve on top of your propane tank to the open position, then press a small button on top of your heater for 30 seconds. This will ignite an electric spark inside that lights up your pilot light.


When your heater is on, and the pilot light won’t light, it’s time to troubleshoot the problem. Make sure all of your fuel lines are connected properly and there are no leaks. If you have a consistent problem with an air leak, tighten up your fittings or replace them completely. If you’re still having issues with lighting it up, check your gas supply tank for water in its contents. Once you have done all these regular checks but there is still a problem, then it might be time to involve an expert.
