SOURCE: my Lennox G10R03-110-1 heat unit, will not light

Hi,
You have a pretty old Lennox there. The G-10's went out of production many years ago....
Since you have pilot and the thermocouple was replaced you will need to check and see if there is voltage going to the gas valve. You should have 24v AC across the two wires on the gas valve when there is a call for heat. If not then the limit switch or the high limit switch are cutting the power to the gas valve. You will need to reset or replace them.
If you have power to the gas valve then you have a
faulty gas valve and will need to replace that.
It if very possible that the gas valve has failed on a furnace the age of yours. That would be my first guess. But do check for voltage before replacing it.

I hope that this will help you to solve your problem!

Thanks for using Fixya!!

The part you described is the heaters Control Valve for your Infrared Gas Heater. It is an expensive part to replace. If one is still available for your older unit.

You failed to mention where (what country you're in), but Vulcan has been popular in Australia for many years, So I'm assuming you're in Australia.

Below is a link to contact information for Vulcan in Australia, b region. Hope this helps you find a service technician.

Napoleon Fireplace propane Pilot won't light main burner even though gas flows in?


  • I'm going to assume your fireplace has a pilot light.
  • Follow the little holes in the burner that lead to the pilot light.
  • Make sure the pilot flame is pointing directly at the closest burner hole. (adjust if necessary).
  • Often, you will need to sprinkle a layer of "glowing embers" in this area. The embers will help the gas travel to the pilot light and ignite.
  • Always start your propane appliance on "High" never "Low". Cold propane likes to drop to the bottom of the firebox and accumulate until it reaches the pilot (this is called delayed ignition). Keeping it on "high" will help the fuel travel over to the pilot without buildup.

I lit my gas fireplace and left the room. When I came back both the pilot and main burner were off. I figured my t-couple dropped out. Turned the valve to pilot, pressed the knob down, hit the ignitor and...


Pilot must have gone out along with main burner ,but it takes 30 secs to shut off would say you hit the ignitor at the wrong time to blow out glass . So you will need a new glass if broken , clean pilot and burner I would change thermocouple , then checkif gas valve is not sticking open . Maybe best to get local gas company to check this all out.

Water heater burner wont light


Problem is not thermocouple:
Thermocouple should be finger-tight plus 1/4 turn
Overtightening will short thermocouple against gas control valve, and solenoid switch will not open, and no gas will reach pilot once red button is released.
Tip of thermocouple has to sit in the pilot flame.
If pilot flame will stay on, then thermocouple is good.

Problem is not solenoid switch.
The gas control valve solenoid opens and closes gas supply to gas control valve.
On mechanical gas control valve, when you push down the red button to light pilot, then you are opening the solenoid and letting gas flow into gas control valve.
When heat is applied to thermocouple, a small electric current travels to gas control valve, and this causes solenoid to stay open.
If you extinguish pilot, then no current travels to gas control, and solenoid clicks off.
You can hear it click, and this is how you test it.
However, since you are getting gas to pilot light, then the solenoid is not the problem.

This leaves 4 possible problems:
1) Bad gas control valve thermostat.
http://waterheatertimer.org/pdf/How-to-replace-water-heater-gas-valve.pdf
2) Inadequate gas pressure. Call gas company.
3) Dirty combustion parts. Clean the burner with wire brush and water.
4) Clogged air intake on FV water heaters: Rheem FV gas water heaters have glass vial that will break if combustion is slowed by clogged air intake.

Burners work fine, pilot light in oven is on, but oven won't ignite


Make sure the thermocoupler is being heated by the pilot light flame. It could also be gunked up but you can clean it with a scouring pad, or it might need to be replaced. The thermocoupler is the most likely cause because if it isn't heated then the gas valve will not open up and no gas will flow to the burner. Since your pilot light is on then you do have gas to the valve.

We have not turned the heater on since 2010. it is a gas with fake logs.A rennai flame fire inbuilt standards. Husband says the thermacouple is not working? what do you recommend?


Stephanie, I 'm not sure how it was determined, that your direct-vent gas fireplace needs a Thermocouple? As a dirty pilot light will also mimic a faulty thermocouple. In addition, if the fire hasn't been used since Winter of last tear, and the gas line to the unit has been turned OFF since then, the air in the gas line must be purge, before the Pilot will light and hold.

If all of the above can safely be ruled out, then the thermocouple should be replaced. The facing of the fireplace will have to be removed, to access the Thermocouple.and it's connections to the gas control valve. You didn't mention which Rinnai Gas Fireplace you have, but most if their units, use Thermocouple part # 90193475. If you're going to replace it, it would be a good idea to also replace the Thermocouple Retainer, part # 9377.

I hope this helps you to further troubleshoot and solve the problem. Please let me know. Thanks.

Gas fireplace wont stay lit- it is a sealed unit so can taccess the pilot or gas holes in the logs. is it safe to remove glass panel?


Yes, removing the glass is safe, if you do it carefully, so as not to break it. Put it well out of your way, after removing it. In fact, removing it is the only way to access and service the Pilot Assembly and the Burners.

If the pilot won't stay lit, there are several things that can cause this on a Direct Vent Gas Fireplace:
  • The direct vent on the outside of the house is block or clogged.
  • Wind is blowing back through the direct vent, blowing out the pilot.
  • Low gas pressure
  • A dirty pilot.
  • The thermocouple and/or Thermopile (part of the pilot assembly) has failed.
If you can provide me with the make and model number of your gas fireplace, I may be able to furnish you with an Owners Manual, that will help you to continue to troubleshoot the problem.

Hope this helped you.

I have a Marco gas fireplace model# 794019C. It is the millivolt pilot generator type. I first changed the thermopile and cleaned the spark ignitor to get it to light. I have checked continuity and...


Mike, I suspect that the problem you're having is not related to the new Thermoplie (Pilot Generator) you installed. Its with the Thermocouple. The clue was "Some of the time its hard to keep the pilot light lit". The Thermopile controls the opening and closing of the gas valve, when the wall switch is turned ON/OFF. The Thermocouple, is what keeps the gas valve open and pilot light lit all the time. If there's no flame heat on the Thermocouple, it closes the gas valve. Rather than replace it, you can try polishing it with some very fine sand paper, then wipe the tip with a cotton ball soaked in alcohol. If the Thermocouple is really pitted, don't attempt this. Just replace it. If you do replace it, when you make the connection to the gas control valve, finger tighten the nut, then tighten only 1/4 turn more with the appropriately sized wrench.

By the way, MARCO is no longer in business as MARCO Fireplace. It was purchased by Lennox Hearth, a division of Lennox Heating. And your model firsplace is no longer manufactured. If you continue to have problems with it contact Angie Parrish at Lennox via email angie.parish@lennoxhp.com.

Hope this helped you solve the problem. Please be kind enough to rate my response to you. Thanks and have a good day!
