SOURCE: Unable To Keep Pilot Light Lit!

I have a Williams top vent gravity wall furnace (model 5009622) and I had the same problem. I had to take the cover off the furnace -- screw on top and two at the bottom (open the access door and there is one screw on each side) to get to the reset button for the vent safety shutoff system. On my furnace it's on the left side toward the top of the unit. I pressed the little red reset button and it's been working ever since. If your furnace is properly installed and doesn't have bird's nest in the chimney, it should work fine. Good luck!

SOURCE: Stadt Ducted Heater ignition problems

Could be a number of things
Sounds like it the gas valve. If the gas Valve isn't opening or is burnt out then no gas will flow through it.
Also it the pilot is blocked then you wont get and gas coming through to light it up.
I am forever replacing gas valves on the buffalo series units and have found this to be quite a common problem on older units.

SOURCE: Natural gas hot water heater not stying lit

Probably a bad solenoid in the gas valve. Higher voltage of a new thermocouple keeps it open longer but it still fails over a period of time. Look into a new gas valve for the water heater.

The pilot light on the water heater went out and the red light is blinking four times on the thermostat (Honeywell WV8860B1317). How do I get this to stop so that the pilot light can be relit?


The flashing light 4 times indicates high water temperature has activated the over heat sensor, and that the only remedy is to replace the gas control valve/thermostat.

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.

Have a Reddy Heater RCP275 propane gas heater. If able to light - the heater will burn for 1-5 min. but then goes out. Sometimes burner will not light at all when the red pilot button is released. At times...


Sounds like the igniter needs to be replaced. It is normal for a heater to run five or so minutes that means the thermostat is working. then restart when the temp calls for heat but if the igniter does not work it will not light up again.

Describe your Problem i have a quasar vulcan gas heater pilot light is on but wont ignite. can hear it clicking trying to ignite what is the o=problem . this heater maybe about 20 years old


What do you mean by the pilot light is on but won't light. Do you mean that there is gasbut won't light. If so the spark may not be hitting the pilot properly or it may not be getting enough gas. If lighting but continuing to spark the sensor may need cleaning. This can be cleaned with steel wool (not sand paper), probably will need to disassemble the pilot asembly The pilot may also be dirty reducing gas flow. If this is the case dis-assembly will be needed and the pilot cleaned.

New gas water heater pilot light will not ignite


Hi .. if this is a brand new heater, then you probably need to have the gas line bled. This means getting all the air out of the gas line feeding the burner. This can be done by constantly trying to light the burner or poilot . or it can be bled down by a HVAC tech.

Gmp100-4 initer lows and I can hear gas for a few


The red blinking light just means that it went into lock out mode from to many attempts to start. If your igniter is glowing and you do hear the ''hissing'' sound, than your problem is there is no gas or not enough. When installing a furnace for the first time, you some times have to bleed the gas lines, other wise you get the exact same problem your having. If you have a flexible gas line, unscrew one side with the gas on to bleed off the air in the system, if it's all hard pipe, you will have to undo the union and bleed it that way. Hope this helps and good luck!

Faulty Junkers water heater


first find out from your manual what the flashing red light means...that should narrow your search---could be a thermocouple shot,a rubber diphragm in the gas valve has weakened and not operated, or gas pressure into the appliance may suddenly be too low, or springs in gas valve may have worn out---very many possibilities

Wont light


Is there a spark? or do you need a long match? The button usually just opens the pilot so it can be lit. If its not electronic.

How do I light the ignite pilot light


Most new dryers don't actually have pilot lights. They use an electric heater that turns red hot, and ignites the gas at the right time. If your trying to light the pilot light (which probably doesn't exist) because the gas isnt being ignited,,, its possible that the electric igniter needs to be replaced.
