Resetting the tilt switch on a patio heater is a fairly straightforward process that can usually be done in just a few minutes. The tilt switch is a safety device that shuts off the heater if it gets knocked over or tilted more than a certain amount. Over time, the switch can get stuck or fail to reset properly after the heater has been righted. Resetting the switch will allow you to get the patio heater working again.

What is the tilt switch on a patio heater?
The tilt switch on a patio heater is a basic device designed to cut off the fuel supply and shut down the heater if it tilts beyond a certain angle. It’s a safety mechanism intended to prevent fires or explosions if the top-heavy unit gets knocked over.
The tilt switch is wired into the control circuit of the heater. It contains a small steel ball that rests in a curved notch or cradle. When the heater is upright, the ball stays put, keeping the switch closed so that electricity can flow and the heater can operate normally.
If the heater tilts more than around 45 degrees in any direction, the ball will roll out of the cradle, opening the switch and breaking the circuit. This cuts power to the fuel supply, shutting off the burner.
Once the heater is put fully upright again, the ball should roll back into place, resetting the switch so the patio heater starts working again. If the tilt switch gets stuck, it may need a manual reset.
Signs the tilt switch needs resetting
Here are some signs that the tilt switch on your patio heater may need to be reset:
- The heater shuts off and won’t turn back on even when upright.
- The heater works but keeps turning off unexpectedly while in use.
- You recently knocked over or tilted the heater.
- The heater was left in a tilted position for a long time.
- You hear the ignition clicking but the burner won’t light.
If you’re seeing any of these issues, the tilt switch is likely stuck open and needs to be reset to function properly again.
How to reset the tilt switch
Here is a step-by-step guide to resetting the tilt switch on a patio heater:
- Make sure the patio heater is on a flat, level surface.
- Check that the propane tank is full and connected properly.
- Locate the tilt switch, usually attached to the lower pole around knee height. It may be in a small box with a button or lever on it.
- Toggle the master power switch off and then back on to reset the main control module if there is one.
- Press the button or flip the lever on the tilt switch box fully to the opposite position. Leave it for 30 seconds before returning it to the original position.
- Turn on the heater again and press the ignition button. It should now spark and light as normal.
- If the burner won’t light, cut power at the master switch again for 30 seconds and retry. This may take a couple of tries.
- You can also try unplugging the heater briefly if resetting the tilt switch itself doesn’t work.
This process should reset the tilt mechanism so the ball rolls back into place, closing the safety switch and allowing the patio heater to turn on again.
Manual override
Some patio heater models have a manual override switch or button near the tilt switch. This lets you temporarily bypass the tilt sensor to light the heater even when tilted. This can be useful for troubleshooting issues with the tilt mechanism itself.
Use the manual override very briefly just to test operation – never leave it on for regular use as this defeats the safety shutoff protection. Make sure to reset it to normal position again before walking away from the unit.
Cleaning the tilt switch
If resetting the switch doesn’t resolve the issue, the tilt mechanism itself may be dirty or corroded. Dust, dirt, moisture or debris can prevent the ball from moving freely to open and close the switch contacts.
Carefully open up the tilt switch box and wipe any visible contamination away using a dry cloth or cotton swab. Spray contact cleaner into the switch mechanism to dissolve any stuck deposits. Work the button or lever back and forth repeatedly to loosen any binding.
Be very careful not to damage any of the delicate internal parts. Also avoid getting any lubricants or solvents on the electrical contacts. Usually just cleaning and exercising the switch will get it unstuck.
Replacing the tilt switch
In some cases, the tilt switch may be cracked, worn out or permanently defective and require replacement. Replacement tilt switch kits are available at hardware stores or online for most patio heater models.
Switch replacement just involves disconnecting the old switch, removing it from the mounting bracket, and installing the new one in its place. It’s a basic electrical connection that can be done in under 5 minutes, but be sure to confirm the correct part for your heater brand and model.
Preventing tilt switch problems
You can take a few simple precautions to avoid issues with the tilt switch and keep your patio heater working reliably:
- Position the heater on a flat, level surface and don’t tilt excessively while running.
- Shelter the heater from wind, rain and bad weather when not in use.
- Turn off the fuel supply at the tank when not in use for extended periods.
- Maintain the heater according to the manufacturer’s instructions.
- Handle the unit carefully when transporting or storing to avoid bumps.
Taking care of your patio heater and being gentle with it will minimize problems. But if the tilt switch does fail or get stuck, just follow the reset procedure outlined to quickly get your heater working safely again.
Conclusion
Resetting a stuck patio heater tilt switch is usually a quick and simple fix. Try toggling the power, manually operating the tilt switch lever, and cleaning the contacts. If needed, replace a damaged tilt switch with a new one. With basic maintenance and handling, the tilt sensor should operate reliably for many seasons of outdoor heating.

Frequently Asked Questions
Why does my patio heater keep shutting off?
If a patio heater repeatedly shuts off during use, the most likely culprit is the tilt switch getting tripped. This safety device will automatically cut power if the heater tilts too far in any direction. Frequent shutdowns usually mean the tilt mechanism needs to be reset or the heater repositioned on more level ground.
Where is the tilt switch on my patio heater?
The tilt switch is typically located low down on the main pole, around knee height or lower. It may be inside a small plastic housing with a switch lever or button on it. Consult the user manual to confirm the exact location if you’re having trouble finding it.
Why won’t my patio heater ignite?
If you hear the igniter clicking but the burner won’t light, the problem is likely a tripped tilt switch preventing fuel flow. Reset the tilt switch and try the igniter again. If that doesn’t work, low propane levels could be preventing ignition. Refill the tank and troubleshoot further if needed.
Should I lubricate the tilt switch?
No, you should never lubricate or oil the tilt switch mechanism. This attracts dirt and debris which can cause malfunction. The contacts are already designed to operate smoothly. Just wipe away any visible dirt with a dry cloth or cotton swab to clean if needed.
How do I override the tilt switch manually?
Some patio heater models include a manual override button or switch to temporarily disable the tilt shutoff function. This is only intended for brief testing though – never bypass the tilt switch in normal operation due to the fire risk if the heater gets knocked over.
Conclusion
The tilt switch is an important safety device to prevent patio heater fires or explosions. While problems with the tilt mechanism are frustrating, the reset procedure is fairly quick and straightforward in most cases. With routine care and maintenance, the tilt switch should provide years of trouble-free operation.
