Re: Burneer wont stay light afer lighting
You can test all the parts with a multi meter, My only concern is that the thermocouple you got is either not the right one, or it is wired wrong and the wires may need to just be switched around, if that doesnt work then take a multimeter and check for voltage at the Limit switch (thermo disc) and see what you get, you can also check to coninuity at the limit switch if it is opened or closed, if it is closed replace if it is open then it is still good

yes this would appear to me to be the classic symptoms of a bad thermistor , this little device proves that fire has lit (via heat) and keeps gas valve open , otherwise gas valve times out and shuts off (safety)
turn gas supply on....turn gas valve to pilot....press down and hold to allow gas to come through pilot tubing.....light the pilot right by the thermal couple, once lit hold valve down for about 60-90 secs...then release ur hand on the gas valve and turn the valve to on position............make sure the bloody tstat is turned off before doin anything other wise burners will fire up soon as you turn valve to on position
Hello, if the burners light but do not stay on for more than 10 seconds, I would clean the flame sensor. The flame sensor is a metal rod that is on the opposite side of the Igniter, sometimes it gets coated by oxidation and does not sense the burner flame and shuts the Furnace down. To clean to kill power to tje furnace, remove flame sensor and clean with a steel wool, then reinstall and start Furnce back up. If this does not work then most likely the Igniter is too weak to ignite the gas and will have ro be replaced.
I would first check the gas pressure to your furnace. Then make sure that burners are clean and watch flames when burner first ignites. I have seen burners that were dirty cause delayed ignition that would create a suction when they came on and extingush pilot and burners.
The next thing I would do is change gas valve. Thank you
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
It has a thermo-couple that lets the gas valve know that the pilot light is on. If it does not get the heat signal to the valve, it will not turn on the gas. The end of the thermo-couple has to be in the flame of the pilot, and tight on the other end, and must be tight on the other end.
You need to replace the pilot safety switch which is usually a Thermocouple. It is connected by a thin tube from the gas valve to a bulb near the pilot burner. It should be available at Home Depot or online.
the pilot is there for two reasons one is to light the main burners the second is the safety feature. when the pilot is on there should be a cylindrical tube of metal near the flame. that tube is either a thermalcouple or a thermalpile. the t-couple or t-pile converts the heat energy to small amounts of dc voltage. the dc voltage powers a small magnet inside the valve when the voltage gets to low the magnet will release causing a small "click" and the gas will shut off. one thing that you can do to try and fix it is make sure your pilot is encompassing the top 2 3rds of the T-couple or T-pile and that the flame is strong and not blowing around when the burners come on. the second thing is that the T-couple or T-pile may have become weak with age, the only way to test the out put is with a special inline adapter. nice thing about T-couples and T-piles is that there a fairly in-expensive part. hope that helps some. good luck
I called Nexgrill technical support at 1-800-913-8999. They are sending me a new thermo couple to keep the valve open when ignited - so the patio heater will stay on. I needed to give them the serial number (inside the propane tank door) and fax them a copy of the receipt.
