Why does burners and pilot forced off after burners are engaged


We get asked this question many times.

If you light your pilot light, hold in the button and then when you release it and the pilot light goes out, generally you need a new thermocouple. Gas repairs can only be undertaken by a qualified gas technician so you can't do this job yourself.

The thermocouple is a safety device that recognises that the pilot has a good flame and is enough to ignite the main burners. The thermocouple open that valve to the burner.

In limited circumstances the thermocouple doesn't need replacing, either the shield that aims the flame to the thermocouple has become dislodged, or the pilot jet is a little blocked by debris. Either way, having the appliance serviced by a qualified gas fitter is the way to go. I am sure you will have seen news stories about explosions caused by gas leaks and faulty appliances.

How do i light pilot light?


Remove front cover,or just lower section if you can. they usually just need to be lifted up about an inch or so and pulled out. However some have covers that snap in place. After you remove cover locate gas valve. It should have a control knob on top with markings for on, off, and pilot. Set control to pilot. Follow lines from gas valve to burner compartment, one goes to main burner one ,small copper colored line is the thermocouple, other line is the pilot. Turn thermostat down as far as it will go. Make sure gas supply valve in line to heater is on and then depress pilot control , when you have pilot control depressed have a match or other small flame source close to pilot assembly. If it lights then hold down on pilot control for a couple of mins. Slowly release pilot control and if it stays lit turn gas control to on. Turn thermostat up to call for heat and burner should light. If pilot doesn't stay lit when you release pilot control then try again holding pilot down longer. If it still won't stay lit then thermocouple will need replace. Good luck. Thanks

Burner will not light. With the pilot light burning and the gas is turned-on to ignight the main burner the pilot light goes out.


call aservice tech your pilot light might be blocked therefore the pilot flame might not be strong enough to handle the puff of gas when the gas valve opens ps. if the unit is off in the summer spiders are usually the problem. Hope this helps

Pool Heater Light main burner then goes out


take millivolt reads while main burner is on.i suspect you will see a drop in voltage until you get to point where it will no longer operate burner(around 200mv).if this is the case you probably have poor pilot characteristics due to dirty pilot,pilot out of adjustment ,obstruction or insufficient gas pressure
