Troubleshooting Patio Heater Gas Control Valve Issues And Other Problems

Outdoor patio heaters are a great way to extend the use of your outdoor living space, providing warmth to enjoy the fresh air all year round. These heaters can also be expensive, so when something goes wrong, it is important to try and fix it.

The issue can be a variety of things, from patio heater gas control valve issues to screws that don’t seem to get tight enough.
 

The Pilot Ignites, But Once You Turn The Setting To High Or Low, The Pilot Goes Out.

This is usually an indication of a loose connection between the patio heater gas control valve and pilot assembly. If this is happening to your heater, tighten the connection and check for any gas leaks.

This can also happen if the cylinder is not at least 2/3 full and functioning properly, if there is a blockage in the pilot, if the tip switch connection is not good, or if the thermocouple needs to be replaced.
 

The Pilot Won’t Light.

There could be several reasons why the pilot won’t light. Start out by making sure the cylinder valve is open and then try to light the pilot manually. If that works, you will need to replace the igniter switch.

If that doesn’t work, make sure there is no air in the gas line by bleeding it for about two minutes. If that doesn’t work, check to see if there is a blockage in the pilot tube or orifice. Finally make sure there are no kinks in the regulator hose.
 

The Pilot Lights, But The Burner Won’t Light.

There are two situation in which this situation occurs. The first situation that could cause this problem is if the pilot flame is not going through the hole in the pilot shield. This could be due to a clogged main burner which requires cleaning.

The second situation that could cause this problem is that the burner ports or venturi tube is clogged. To troubleshoot this problem, try cleaning the burner supply tube buy removing the supply tube nut to access the orifice. If that doesn’t resolve the problem, then verify that the tip switch connection is good. Finally, use soapy water to check for leaks.
