If your Mr. Heater keeps shutting off, it may be due to a clogged air filter or a problem with the oxygen sensor. If the air filter is clogged, it can restrict the flow of air to the burner, causing the unit to shut down. To clean the air filter, turn off the unit and remove the filter.
Clean the filter with warm soapy water and reinstall it. If the oxygen sensor is defective, it may need to be replaced.
If you’re like most people, you rely on your Mr Heater to keep you warm during the colder months. But what happens when your heater starts shutting off unexpectedly?
There are a few reasons why this might be happening.
First, it could be due to a build-up of dust and debris in the unit. This can happen over time and will eventually cause the unit to overheat and shut down. To fix this, simply clean out the unit according to the manufacturer’s instructions.
Another possibility is that there is an issue with the gas line or regulator. If there is any damage or blockage in these components, it could cause the heater to shut off. You’ll need to have a professional take a look at these parts to determine if they need to be repaired or replaced.
Finally, it’s possible that the thermostat is set too low. If this is the case, simply adjust it upwards until the heater stays on as desired.
If your Mr Heater keeps shutting off, don’t panic!
There are a few simple things you can do to troubleshoot the problem and get back up and running again in no time!
Mr Heater Shuts off After 5 Minutes
If you’re using a Mr. Heater and it shuts off after just five minutes, there are a few things you can check to try and troubleshoot the issue. First, make sure that the fuel tank is full – if it’s not, the heater will shut off automatically after five minutes in order to prevent damage. If the tank is full, then check the air intake and exhaust vents to make sure they’re clear and not blocked by anything.
Finally, if those two things are fine, then there may be an issue with the igniter – you’ll need to contact Mr. Heater directly for assistance with that.
Mr Heater 30 000 Btu Keeps Shutting off
If you’re like most people, you rely on your furnace to keep your home warm and comfortable during the winter months. So, it’s frustrating when your furnace keeps shutting off unexpectedly.
There are a few possible reasons why your Mr Heater 30 000 BTU unit might be shutting down prematurely.
First, it could be due to a problem with the thermostat. If the thermostat isn’t set properly, it can cause the furnace to cycle on and off more frequently than normal. Second, there could be an issue with the flame sensor.
This component is responsible for detecting whether or not there is a flame present in the burner chamber. If the sensor is dirty or damaged, it may not be able to accurately detect the flame, which can cause the furnace to shut down. Third, the pressure switch may not be functioning properly.
This switch signals to the furnace that there is enough airflow present in order to safely operate. If the pressure switch is faulty, it could prevent the furnace from turning on at all.
If your Mr Heater 30 000 BTU unit has been shutting off prematurely, try checking these three components first.
If you’re still having trouble after troubleshooting these issues, then it’s time to call in a professional for help.
Mr Buddy Heater Shuts off After Few Minutes
If you’re using a Mr. Buddy heater and it shuts off after only a few minutes, there are a few things you can check to see what the problem might be. First, make sure that the fuel tank is full – if it’s not, the heater will shut off automatically after a short time. Next, check the filter to see if it’s clogged or dirty – if it is, clean or replace it.
Finally, check the exhaust vent to make sure it’s clear – if it’s not, the heater will shut off due to lack of ventilation. If all of these things are in order and your heater still won’t stay on for more than a few minutes at a time, give us a call and we’ll help you troubleshoot the problem.
Mr Heater Troubleshooting

Propane Heater Keeps Shutting off
If your propane heater keeps shutting off, there are a few possible reasons. The most common reason is that the pilot light is out. If this is the case, simply relight the pilot light and see if that solves the problem.

Why Does My Mr. Heater Propane Keep Shutting Off?
If you’re having trouble with your Mr. Heater shutting off, there are a few things that could be causing the problem. The first thing to check is the fuel level in the tank. If the tank is empty or nearly empty, it will cause the heater to shut off.
Another possible cause is a blockage in the fuel line. This can be caused by dirt or debris in the line, or if the line is kinked. Check to make sure the fuel line is clear and not kinked, and if necessary, clean out any debris that may be blocking it.
Finally, if none of these other solutions solve the problem, it’s possible that there is an issue with the heater itself. In this case, it’s best to contact Mr. Heater customer service for assistance troubleshooting the problem.
How Do You Fix a Mr. Heater That Won’T Stay Lit?
If your Mr. Heater won’t stay lit, there are a few possible causes and solutions:
1. The first thing to check is whether the pilot light is still lit. If it’s not, you’ll need to relight it according to the instructions in your Mr. Heater manual.
2. Next, check that all the venting pipes and vents are clear and unobstructed. If there’s any blockage, this could be causing your Mr. Heater to go out.
3. Another possible cause is a dirty or faulty flame sensor.
This part can become clogged with soot over time, preventing the sensor from detecting a flame and causing the heater to shut off. To clean the flame sensor, simply remove it from the heater and scrub it with a wire brush or sandpaper until it’s clean (be careful not to damage the sensing element). You may also need to replace the flame sensor if it’s damaged beyond repair.
4. Finally, if none of these solutions work, you may have a problem with your gas valve or thermocouple (a safety device that shuts off the flow of gas if no flame is detected). In this case, you’ll need to call a certified technician for help diagnosing and repairing the issue.
Why Won T My Mr. Heater Stay On?
If your Mr. Heater won’t stay on, there are a few potential reasons why. The most common reason is that the pilot light is not lit. If the pilot light is not lit, the gas will not flow to the burner and your heater will not turn on.
Another potential reason is that the thermocouple is not working properly. The thermocouple is a safety device that senses when the pilot light is lit and tells the gas valve to open. If it isn’t working properly, it may prevent the gas valve from opening and cause your heater to shut off.
Finally, if there is dirt or debris in the gas line, this can also prevent your heater from staying on. If you think any of these issues might be causing your heater to shut off, please call a qualified technician for assistance.
How Do You Clean the Thermocouple on a Mr. Heater?
If your Mr. Heater isn’t working correctly, one possible issue is a dirty thermocouple. The thermocouple is a safety device that shuts off the gas flow if the pilot light goes out. Over time, it can become covered in soot and other debris, which interferes with its ability to function properly.
Here’s how to clean your Mr. Heater’s thermocouple:
1. Turn off the power to your Mr. Heater and allow it to cool completely.
2. Disconnect the thermocouple from the control valve at the base of the unit.
3. Use a wire brush or other stiff bristled brush to clean any soot or debris from the end of the thermocouple that attaches to the pilot light assembly.
