Pilot Orifice plugged

Dirt Dauber found its way into the pilot light assembly this summer. I have cleaned the barrel but the orifice is plugged and will not come clean. Where can I find a new orifice. It screws out not much to replace just to locate.

Take the thing out and soak it in water. this will break down the mud the wasp uses to make its nest. then blow the thing out with compressed air.

My wall mount propane heater sputters and won't fire up when I turn the knob to on

this quote is taken from site below under Problem Identification.

If the burner sputters on ignition or takes more time to ignite, there is definitely a blockage of the pilot orifice by dirt and dust. Set the pilot at a higher level and clean the orifice along with the burner ports.

Have problem with w355 f cozy wall heater won't turn on with pilot light working. Sometimes if I bang on the valves control it will lite up.

need to clean out pilot orifice, unscrew the silver tubing from the pilot and a 1 inch long orifice will fall out, clean by either blowing air or a clean out bit, if there is just a small amount of dirt or debris that comes from the gas this will reduce the amount of voltage to the valve.

Pilot light won't light the low flame or stay on

If the pilot light will light at all but not have a good strong flame I would remove pilot assembly and clean it thourghly,being careful not to damage pilot orifice. Reinstall pilot and seeif you have any improvement. If pilot still won't stay lit I would replace thermocouple being careful to make sure top inch or so is in pilot flame. Hope this helps. Thanks

Can't seem to ignite pilot on a 30 year old vulcan heater. Same problem every year as winter is approaching :) Usually works fine once pilot is on though.

It's probably just a dirty pilot orifice (or a spider web), if it's been off since last winter. Try using a can of compressed air with attached straw (like you use to clean computer keyboards) and blow out the dust from the pilot orifice in the pilot assembly, which is where you light it. That should do the trick. Good luck! Douglas

I just moved into a new place, and turned the heater on the first night and was working fine, but then i left when i came back heater was off and could not get on ever since. i followed the instructiond ,...

The pilot remains on because of a signal from the thermocouple to the valve. The thermocouple needs the pilot to remain lit for approximately 60 seconds prior to being able to send a proper signal to the gas valve. Be sure to keep the button pressed for 60 seconds prior to releasing it.
If after 60 seconds, the pilot extinguishes as soon as the button is released, the problem is generally going to be with either the thermocouple or the pilot orifice. The pilot orifice can become clogged which affects the flame. This, in turn, will prevent it from properly heating the thermocouple. I do not recommend disassembling the pilot assembly to clean the orifice unless you are a trained, qualified service technician. If this job is not performed properly it could lead to personal injury and/or death. However, there is a trick that sometimes can try tapping the pilot assembly with a screwdriver.....this can sometimes loosen debris on the top of the orifice allowing for better pilot.
If the flame is not the problem, chances are good you have a bad thermocouple. The thermocouple can be purchased at your local hardware store for approx $10.00 - $20.00. I'm going to include a link to a YouTube video showing you how to replace a thermocouple.
If these steps do not work, you should consult with a trained, qualified service technician. At this point you most likely need to have the pilot assembly professionally cleaned and/or you need to have the gas valve replaced.
ALWAYS remember to keep a working <5 year old Carbon Monoxide detector in your main living area and in your master bedroom. Carbon Monoxide is colorless, odorless, and deadly. If you do not already have these devices installed, GET THEM. They, too, can be purchased through your local hardware store.

Here's the link for replacing your thermocouple. Also observe the pilot light in this video....this is a good, clean pilot light and is what you are looking for.

I hope that you found this information helpful to you.
Good Luck! :-)

Pilot light will not stay lit on model 465FX-R wall mounted gas furnace. Thermocouple was replaced but still won't stay lit. Gas is on at the meter. Any suggestions?

It is possible that gas valve is bad, however, try replacing the pilot orifice located in the pilot assembly. If the flame is inadequate it will not generate the voltage required in the thermocouple. Pilot orifices are less than $10 and can be found at your local heating contractor's parts counter. Bring in the orifice to match.

Heater will not stay light

I had this same problem and the only thing that I found was a small spider web in the pilot air intake which had traped a small piece of lint I blew this out and the heater worked great

Comfort glo propane ventless heater won't light

I have several of these heaters in my rent houses and love them. The most problem I have is not being able to ignite the pilot with the user control igniter. Remove the screws that hold the front cover in place along with the front cover. Hold the pilot control down and ignite with a lighter. Keep the pilot engaged until thermocouple is warm enough to keep pilot gas flowing. If it will light this way then you need to blow out the pilot orifice. It seems that every year I have to go in after the summer season when the heater is off and clean the pilot/orifice lines with high pressure air. I believe spiders/bugs/dust block pilot orifice when it is not in use. You can also tell that orifice is blocked when you don't get a good blue pilot flame with pressure behind it allowing the flame to submerse the thermocouple. If the the thermocouple is not getting enought heat it will turn pilot gas off for safety reasons.

Cozy furnace

The pilot orifice could be dirty causing the pilot flame to be too small. Unscrew the pilot tube at the pilot assembly. The orifice is inside. Remove the orifice and blow it out with compressed air only. Reassemble and see if that fixes the problem. If the pilot flame is set too low, sometimes opening a door will cause a draft to blow out the pilot. If the thermocouple is good and the pilot flame is set properly, the control valve may be bad.

Pilot light has no gas coming out, verified gas going into gas valve, but no gas coming out when pilot light button depressed.

Pilot orifice may be clogged. Remove pilot tube and orifice. Blow out orifice with compressed air only and reassemble. Also, control valve may be bad.
