There is a safety component that has either cutout or failed. It is NOT recommended for the consumer to attempt to service or repair a gas heater without proper knowledge or experience. Do not attempt to bypass any safety component. Call a service center in your area for any any repairs or maintenance.

Lighting pilot light


Pilot assembly is located inside the bottom compartment, between the the two middle burners while the gas valve is located under the burner manifold. Make sure that the gas line where the unit is connected is open. You need to turn the gas valve knob to "Pilot" position and depress it (to allow the gas to flow on pilot) then light the pilot assembly using a lighter with extended nozzle ( burner igniter). Once the flame is present at the pilot assembly, wait for about 15 seconds (allowing thermopile to heat up) the gradually release the gas valve knob. If the pilot flame is stable, turn the gas valve knob to "ON" position and set the thermostat to desired temperature setting. This will ignite the burners and heat up the oil to set temperature. Just remember, do not do this if there is no oil on fry tank.

How do you light the pilot light on the stove? Model 3627391592


Hello,

A pilot light will be found on natural gas stoves, fireplaces, clothes dryers, water heaters and furnaces. When the gas is turned off, the pilot light will go out on all of these appliances. After the gas is turned back on, you must relight the pilot light before you can use the appliance. Pilot lights are similar so if you can relight the pilot light for a gas heater you can relight the pilot light for a gas stove or any other gas appliance.


jQuery('.intro .thumbnail').each(function(i,e){ jQuery(e).find('img').one('error',function(){ jQuery(e).remove(); }); }); Instructions Things You'll Need:

  • matches OR flashlight
  1. Locate the gas valve by following the gas line in the appliance. The gas valve will have a large red button or knob and will be easy to see and will be well marked.
  2. Check for a gas leak by smelling the area close to the gas valve. Listen carefully for escaping gas and do not attempt to light a pilot light if there is a gas leak.
  3. Hold down or press the red button or knob on the gas valve while holding a lit match in front of the opening in the gas pilot line. Continue to hold down or press the red button or knob for several seconds after the gas ignites to allow the thermocouple (the sensor for the appliance's thermostat) to heat up.
  4. Repeat step 3 if the pilot light goes out after you release the button or knob. In most cases, the pilot light goes out because the thermocouple did not have enough time to heat up, so give it a few more seconds.
  5. Make final adjustment of the gas flow to the pilot light by turning the red knob. In some cases, no adjustment other than "on" or "off" will be needed.
  6. Turn on our appliance to make sure the pilot light ignites the main gas flow. Replace any covers or close any access doors to the gas valve.
Hope this help?

Thanks for using fixya.

Why would the pilot light ignite then turn off?


If it is a true "pilot" light, it needs to be held down long enough to generate the milivolts needed to prove to the gas valve that he is ready to open, other wise the gas valve would open, not igniting, thus causing a "gas leak". Turn the t-stat OFF, turn gas valve to pilot, push down on pilot knob, light pilot and hold for 2 minutes. After 2 mins let go, and if pilot stays lit, turn gas valve to ON, and turn the stat to heat and turn it up to desired temp. If pilot does not stay lit after doing above, try sanding thermo couple( the thing the flame is sitting in) or just spend the $15 bucks and replace therm couple. azeddysac@yahoo.com

How do i light my heater pilot light? My gas was turned off temporairly but is back on and I need to relight my pilot light.


Your pilot is a spark ignition so it will start itself. You will probally need to bleed the gas line to get it to start. Do this by opening the union outside the cabinet and turn the gas on till you can smell it. Shut the gas off and tighten the union up again and let the gas clear. Then start the gas and seeif it will light at that point.

I have a Maytag gas over/stove, Model number MGR5755QDW. The broiler heats, but the oven does not. What are the possible causes and how do I troubleshoot?


If you are having problems with the oven, the first thing to do is figure out if you have a pilot light system or a glow bar system.
Problems with the pilot light system.....The flame has gone out, re-light the pilot. The pilot flame will not light - possible oven control is not sending gas for the pilot light. The pilot light works but no main burner ignition - possible pilot assembly is dirty and the pilot flame is too small, safety valve and thermocouple is faulty, the bulb from the safety valve is out of position and the pilot flame is not touching the thermocouple bulb. Some ranges use a standing pilot light ( small flame is on all the time ) while others use an spark ignition to light the pilot light flame and the pilot light flame heats up the thermocouple bulb to allow the main gas to flow through the oven burner.
The flame needs to heat the bulb up enough to tell it to open the gas valve. Several things can go wrong here that keep this from happening:
The pilot flame may not be hot enough, usually because the flame is yellow instead of pure blue or is too small. The cause for this is usually a dirty pilot assembly. The pilot assembly would either need to be cleaned or replaced.The thermocouple bulb may not be positioned properly in the flame. You can't heat the bulb properly if it's not in the pilot flame! The thermocouple bulb needs to be in the upper third of a pure blue pilot flame--that's the hottest part of the flame.
The thermocouple itself may be burned out. It happens. It's a internal part of the gas valve so, no, you can't just change the thermocouple bulb separate from the gas valve.
But when you turn on the oven or the thermostat calls for heat, the pilot flame gets bigger and jumps down so it can heat up the thermocouple bulb. This extra gas to increase the pilot flame size comes from the thermostat.
If the pilot flame jumps upwards or just gets bigger, but doesn't shoot down, then you need to replace the pilot assembly.If the pilot flame size does not increase or jump down when turning on the oven thermostat, then the problem is the thermostat not sending enough gas to the pilot assembly. It's also possible that the pilot gas supply tube has a hole in it somewhere.
One final point on the spark-assisted pilot ignition systems. The spark comes from the spark module--the same module that sends spark to your surface burners to light them up. If you're not getting a spark when you turn the oven on, then there are several possibilities:
There could be a problem with the switch in the thermostat. You can confirm this by doing a simple continuity test of the thermostat contacts. If you don't read zero ohms when you turn the switch on, replace the thermostat.The spark module could be bad. You'll need to measure the voltage at the oven terminals of the spark module when you turn on the oven. If you get 120v but no spark, it's probably a bad spark module. Replace it.
Could be a bad spark wire or broken electrode.
Problems with the glow bar system.....You may even see the orange "glow plug" (called a hot surface igniter) glowing orange and so assume that it's OK. Not necessarily!! You have to measure the current/amp drawn by the igniter and compare it to this repair sheet before you can say it's OK or not. The gas valve has a bi-metal that open when a certain amount of current flows through it to heat it up. The igniter is wired in series with the gas valve. As the igniter gets older or weaker, it's resistance increases to the point where not enough current is flowing to the gas valve bimetal to open it up. As a result, the gas valve never opens up. BTW, a common symptom of the early stages of this problem is erratic temperature control in the oven due to delayed firing of the bake burner while cooking.
The hot surface igniter will not come on - check igniter with a ohm meter, you should have continuity through the glow bar, the glow bar can also crack = new igniter time. The glow bar comes on but the main burner will not light - you should have an amp probe to check properly, but often this is a hot surface igniter problem. The hot surface igniter often looses it's ability to get hot enough to open the gas safety valve. The safety valve can fail, but most times it is just a bad hot surface igniter. The hot surface igniter can also quit part way through cooking , in other words the oven may cycle a couple of times and then it just sits there with the red glow from the igniter. See this service sheet for the proper way and amp readings for the hot surface igniter system. Hot surface igniters do weaken and will eventually generate less heat than they normally could. When this happens they can still allow marginally correct current to flow to the oven gas valve for it to open but not get quite hot enough to ignite the gas burner immediately. When this happens, gas released into the oven can sometimes build up to the point where when finally ignited, the amount of gas lit can cause a small explosion inside the oven or cause an odor of gas with out the oven working. Yes, your glow bar igniter can glow orange-red and still be bad!! How a common gas valve works -click here.

Blower but no heat, no gas or no pilot ignition?


The pilot has to be lit.And to do so turn the knob to pilot.Then press it down and gas will come threw the pilot,then light the pilot,and hold the button down for about 45 seconds,count slow.The pilot has to heat the thermocouple up before the pilot light will stay on.Once it stays lit,turn the knob to on.

I cant find the stove top pilot


Electric Ignition (sparking clicking noise when control knob is turned to "light" setting) do not have pilots. The spark ignites the gas.

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.

Oven will not light


Most gas ranges currently available employ one of 3 basic gas ignition systems; pilot ignition, hot surface ignition system (which uses a 'glow bar' or 'glow coil' - aka an "ignitor") and a spark ignition system. The latter two being referred to as "electronic ignition" systems as they use electricity in one form or another to operate the oven heating system. Only the pilot ignition system has an actual "pilot" (which is a small but real "flame") which might need manual lighting.

If the surface burners of a range are a spark ignition type, the oven IS one of the possible kinds of electronic ignition systems and thus will not usually have a "pilot" which needs lighting. Be aware though that just because the surface burners might light via a spark doesn't necessarily mean the oven uses the spark type ignition system too. spark-anim1.90x11.gif
There is one older style of electronic ignition system which does also use an oven pilot but it is very rare and such a system hasn't been used in oven models since the early to mid 70's. It is the 'constant pilot' *electronic ignition* system
