Is the gas on?

Check that the inlet screen to the gas valve is not clogged.

If the HSI get's hot, then suspect the gas valve has a problem, or the gas valve control board has a problem.

Reply back what you find and I can provide further instruction.

Should the igniter fire constantly?


Hard to answer the question with out the make and model information. Generally heaters that use an electric igniter in place of a pilot light only fire the igniter until the flame is sensed. If it keeps firing after that then the sensor that heats up to tell it the flame is lit could need replacing.

When I try to use my Thermolaire model SU402E, the pilot lights( and stays lit), but the main burner will NOT ignite.. any suggestions as to what could cause this if the pilot stays lit?


Bad igniter? When you 1st try it the gas valve will give enough gas that you would get the burner lit if the igniter was glowing red. If you're desperate you can light the igniter area w/ an aim n flame, but you definitely want to do that w/ caution and crank up your t-stat so the furnace stays on awhile Cuz you'll have to do it again for heat or buy an igniter($40 or so)

The entire igniter should glow, if it does not the temp to ignite the gas is not met and the burners will never light. When replacing the igniter never touch the element part becuae it will create a hot spot on the igniter and fail.

My furnace blower kicks on and the flame lights for about 5 seconds then kicks off. I replaced the igniter recently. The service trouble light blinks continuously.


Your furnace may be kicking out on high limit. Its possible your circ. or blower fan needs to be cleaned. If you don't get enough air moving across you heat exchanger it will kick off on high limit.

We have a Toyo Laser , when it kicks on we get


Tubearz,

You need to look at the igniter guide gasket. That is the gray fiber gasket just behind the igniter flange. When you remove the igniter you may see a black rubber gasket that could be cracked or completely gone. You will need to replace it with the new style ( #17185580). While you are looking, look at the draft tube, where it goes into the fuel sump. If it is cracked it will need to be replaced.

Good luck,

Tom

Nexgrill patio heater won't stay lit


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.

Hope this helps.
