Why Will My Propane Patio Heater Not Light?

If your patio heater won’t light, there are a few things you can check to see if the problem is with the burner, the gas line, or the propane tank.

Check The Burners

If your patio heater does not light, it is likely that the burners are not working correctly. First of all, check to see if the igniter is working by pressing down on the button and watching for sparks.

If there are no sparks, then you may need to replace the igniter or reset the timer. Replacing your igniter is often a straightforward task and you could consider this reliable Universal Igniter Kit for Gas Grill Models, which fits a wide range of patio heaters.

When in doubt, always consult an expert to help identify any issues with your patio heater system. By following these simple steps, you can get your patio heater up and running again quickly and without hassle!

Check The Gas Line

Make sure the gas line is clear of obstructions before attempting to light your patio heater. Failed lights may be due to a build-up of debris on the line or a broken wire in the unit itself.

To check for obstruction, use a torch and look for kinks or cracks in the pipe. For better visibility when checking your gas line, you might find this LED Work Light Torch handy; it’s waterproof, rechargeable, and provides bright illumination.

If you find an obstruction, use a plunger to clear it, and then try lighting the heater again. If the problem persists, call your local gas company and have them come out to inspect the line.

In some cases, a faulty valve may be to blame for failed lights on your patio heater; this will require professional repair service. If your electric starter won’t turn your patio heater on, make sure all plugs are properly inserted into outlets and try another outlet on the same circuit as the heater.

If nothing works, replace the main fuse near the meter and test your heater again. Don’t forget to clean out any ash from grills or smoker pits before using your patio heater – this can prevent problems with ignition later on down the road! Finally, always keep an extinguisher close by just in case things go wrong while using your propane grill – no one wants an accidental flare-up!

Try A New Propane Tank

If your patio heater won’t light, there are a few things you can do to troubleshoot the issue. One common cause of an unlighted patio heater is a bad propane tank.

To test if the tank is good, fill it with gas and try lighting the igniter. Check that the connections between the tank and grill are clean and secure. Make sure there isn’t any sand or debris in the lines leading to the igniter, and clean them if necessary.

Make sure that all of the fittings on the grill are tight-fitting and in good condition. If none of these tips work, then it may be time to replace the entire unit or install a new one altogether. Before making any changes, consult a professional for help; they will be able to diagnose and fix your problem more quickly than you could on your own.

Keep an eye on your unit during the winter months; snow can block escape routes for gases in the tank, causing it to ignite incorrectly when fired up again in warmer weather. Finally, always keep a spare propane tank on hand just in case something happens to your current one – having a backup plan is key when dealing with outdoor equipment like this!

Checking For Flares

If you have a patio heater that uses propane, it’s important to check for flares before using the heater. Flares can be a safety hazard and may prevent your patio heater from working properly.

There are several ways to check for flares: with a flame detector, with an infrared thermometer, or by visual inspection. Once you’ve detected flares, take corrective action by cleaning the patio heater or replacing parts as necessary.

Make sure to adjust the timer on your patio heater before use and keep an eye on it during the winter months when natural gas is harder to come by.

Faulty Burners

If your patio heater does not light, there could be several reasons why. Check to see if the pilot is lit and if there are any obstructions in the path of the flame.

Make sure the spark plug is replaced and that all connections between the burner unit and grill are secure. Sometimes a faulty propane tank can cause problems with your patio heater as well.

In some cases, a clogged or broken gas line may also be to blame for an unlighted patio heater. If none of these solutions work, you may need to call a professional to get your patio heater up and running again!

Incorrectly Placed Pilot Lamp

If your patio heater does not light, it is likely because the pilot lamp has not been correctly placed. The pilot light ignites the gas that powers your patio heater and should be in front of the flame tube orifice.

When replacing a pilot lamp, make sure you match the wattage and type of lamp to your propane grill. If the pilot light does not work, it is usually due to a broken flame tube or an incorrect flammable gas connection.

Repairing a blown fuse is a common solution for incorrectly placed or defective lamps. If your grill uses natural gas, be sure to inspecting the meter every year to ensure that there is enough fuel available for your patio heater.

In some cases, a new flame tube may be required; however, this can also be costly and inconvenient if done incorrectly by a professional technician. Be sure to keep an eye on your grill’s flame when lighting it in cold weather as this may require adjustment of the pilot light mechanism.

Taking periodic measurements of heat output can help you troubleshoot potential issues with your patio heater before they become major problems. . Remember to replace your pilot lamp every three years or when its performance starts to decline

Short Circuit

If you are experiencing a problem with your propane patio heater not lighting up, there may be a short circuit in the system.

To troubleshoot this issue, start by checking all of the connections to the unit. Next, try restarting the unit by pressing and holding down the igniter button for three seconds.

Finally, if none of these solutions work, call an electrician to inspect and repair your patio heater.

Low Propane

If your patio heater is not lighting, one potential cause could be a low propane tank. Check to see if the propane valve is turned on and open.

Make sure the gas line from the tank is connected to the grill or patio unit. If all else fails, you may need to replace the propane tank or igniter assembly.

Be sure to keep an eye on your propane levels and refill as needed to avoid problems in the future.


If the propane patio heater does not light, there could be several reasons. It is possible that the pilot light has gone out, the burner is not working, or the electricity to the unit has been interrupted. Also you can use a good quality patio heater like Bromic Patio Heater to reduce hassle.

Check all of the lights and components on the patio heater for proper operation before troubleshooting further.
