SOURCE: pilot light will not stay lit on model 465FX-R

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.

SOURCE: Pilot lights fine, furnace fires up, when it turns off the pilot goes out

need to have at least 3 feet of vent out of the roof, if it is to low the coll air will cold soak down to the pilot and shut it down.

SOURCE: PILOT FOR EMPIRE WALL HEATER WONT STAY LIT. I HAVE

are you sure the problem is with the thermocouple? is the pilot sharp and blue? it is unconnon for the magnet in a gas valve to go bad but it does happen. place the thermocouple in the valve and with it in front of you heat it with a match or lighter for 30 sec. now try and light the pilot quickly. if it lights the the problem would be the pilot, if not then the valve. is this a milivolt system or hydrolic t stat.

SOURCE: My empire wall furnace does not ignite. It has gas

It could be several things: Is the Control Knob turned from Pilot to ON? If that is the case, wait a few minutes after turning it to ON. That will allow the Thermopile to heat up sufficiently. Be sure the flame is touching the Thermopile. If everything looks correct turn up your Thermostat to higher than the ambient room temperature and see if the burners light. Remember to turn your Wall Thermostat down to the lowest temperature setting before turning the knob from Pilot to ON.

FYI - That Wall Furnace does not have a Thermocouple. It uses a Thermopile instead to generate millivolts of electricity to open the gas valve and maintain the pilot flame.

If it is the Thermopile, you can order it directly from Empire Comfort Systems, as well as download your Owners Manual at www.empirecomfort.com

I AM WORKING ON A COZY W501E WALL FURNACE AND CANT GET THE PILOT TO STAY LIT. i HAVE CHANGED THE GAS VALVE, THERMOCOUPLE,AND THE SENSOR FOR THE HIGH LIMIT. THE PILOT WONT STAY LIT.


Pretty much the only thing that will do that is the thermocouple not generating enough voltage for the valve to say it's OK.
Usually you need to hold the button for pilot lighting for 60 seconds. You can use a meter to check that it's generating enough power. The thermocouple has to be in the pilot flame properly.

How to adjust pilot lite on a furnace


Select thermostat to off. Take front upper panel off of furnace. Looking at gas valve you should see a flat head or straight slot screw. This is the cap to access the adjustment. Look at the body of the gas valve real close. You may need to put on your glasses or use magnifying glass. It should say pilot in very small raised letters. Remove the cap. Look down into access hole and you will see the adjustment screw. It is a nylon screw so be careful not to strip it out. Place the correct screw driver, should be a small phillips or straight head. Turn gas valve to pilot and depress. Light pilot. While holding down, adjust nylon screw clockwise until flame envelopes 3/8 to 1/2 inch around thermocouple. Replace cap. Select heat and verify pilot stays lit. If the flame doesn't stay lit most likely your thermocouple is defective. You can purchase at your local hardware or Home Depot. Length doesn't matter.The thermocouple is heated and sends a DC signal back to the gas valve. There is another screw cap on the gas valve that adjusts gas pressure. Do not try to adjust the gas pressure to the gas valve because you need a special instrument (manometer) to adjust pressure. This device measures the water colume of the gas. A qualified technician would adjust this to 3.5" WC. for natural gas or 11" for propane.

Pilot on my gas furnace won't stay lit


Try cleaning the thermocouple tip if you can see ashes or any buildup on it. If you know the wind isn't blowing it out (had mine blow out from high winds before) then I would change the thermocouple before anything else.

What is a thermocouple and what does it look like


A thermocouple is a bi-metallic junction that when heated gives an small electric output. The tip of it sits where the pilot light is ( and it is a copper tube going to the gas valve) and the pilot light heats it up. It creates electricity after it heats up (which is why you have to hold the pilot light knob down when lighting) and opens the gas valve to keep pilot light lit after you let the pilot knob go back up. When it stays lit without having to hold it down, (make sure the thermostat is set low so it doesn't light the burner while you have your hand down there) then you turn the pilot knob to on. It should stay on and you can set the furnace to heat and raise the temperature where you want.

Pilot Light won't stay lit on wall furance


The low voltage wiring and the thermostat has noting to do with the pilot function of the wall furnace, check to see if when you have the pilot lit manually, while holding the button in does the flame impinge on the thermocouple and does the flame try to wrap around the thermocouple? if not the thermocouple and pilot flame need to be adjusted so that it impinges on the TC, if it does have a good flame impingment, then you probably have a bad TC from the factory, call them and have them send you a new one if still under warrenty.

Pilot light will not stay lit


Will it stay lit for a while? If so light the pilot light, Turn on the blower fan, and watch the pilot light. Look for any air that's blowing the pilot light around. if the pilot lite is moving around then you could have a bad heat exchanger. If so you should get a carbonmonixide detector and have your furnace inspected for this. One thing to check also is make sure the thermocouple is at least 1/4 inch into the flame.
