If the gas supply fails whilst a burner is lit is there a safety shut off that prevents gas flowing again when the supply returns.

Most unlikely. The pilot lamp will also extinguish. Better close the gas knob on the burner and relight the pilot when the supply is restored. usually you can see the pilot light lit from the bottom of the range when you open the oven door. and the burner suface is warm-hot where the pilot is located below it.

No heat, ignitor goes on burner goes on sometimes and after short time goes out. ignitor goes back on, but no burner. what up


If the flame sensor is not returning a good signal, the gas valve is shut off as a safety measure. I surmise that in this situation, the igniter is programmed to fire for a time to flare off any accumulated gas from the initial attempt to fire up the burner.

Check for the following: adequate combustion air supply (make sure inlet vents are clear), proper exhaust venting, flame sensor properly positioned and not cracked or otherwise broken, burner holes are clean and not caked over with combustion deposits (if the flame is uneven and weak right where the flame sensor is located, it will be treated as a failed ignition).

In the worst case, the gas valve is defective and unable to detect the flame signal. It's also possible that a thermostat is sending an overheat signal, but that doesn't account for the igniter sparking a second time after the burner shuts off.

My right front burner does not work on low. it does not turn on until you turn the knob to about the medium setting


many burners have safety mechanism that shuts the flow of gas when it is cold. it is there to prevent the flow of gas in the case when the fire was put out by wind or split of water.
you didn't mention if after the fire is lighted, are you able to turn the knob back to low.

My vulcan ducted heating unit blows cold air for approx 1 minute when turned on then stops and try's again after approx 1 minute,it does this several times until ignited.It is obviously an ignition...


Two things have to occur here:

1) The ignitor has to light off the gas. A bad ignitor, or dusty burners can prevent ignition.

2) The thermocouple has to be in the flow of burning gas to prevent a safety shut-down, and has to be working.

And the obvious: you need pressure in the gas line, and the gas valve needs to be open.

Hope this helps you locate the problem!

Maytag LDG7400 gas dryer does not stay lit long enough to heat the drum. Can see flame turn on for about 10 seconds then back off for 20 to 30 seconds. Continues cycle of on and off until end of time....


Light sensors detect when burners are lit. If they become blocked with lint, dust, etc., they will not detect the flame and, for safety purposes, automatically shut off the gas flow.

Dust and lint are a dryer's worst enemy. Be sure that all sensing devices (particularly optical sensors) are clear of dust and lint so that light can pass unobstructed into the lens.

If they sensors are all clean, they might be defective. Something is erroneously telling your dryer's control that the burners are not lit and thus the gas supply is shut down.

Flame goes on than out and keeps doing that wont stay lit!!


I'm assuming you're referring to a gas burner that supplements the heat pump. If the burner lights at all, The ignition system is working. If you need to reset it for it to relight, I would suspect the thermocouple. It detects the flame to prevent gas from pouring out of an unlit burner. If it malfunctions, the control thinks the burner didn't light and shuts down for safety.

Burners work,Broiler works but oven does not preheat


If everything works on your range, but the oven, the most likely culprit is the igniter for the BAKE manifold. What is confusing me, though is the statement in your question where you say the "oven will light up, but never get hot". Yet, you say the oven does not ignite. Can you clarify this? In some ovens the BAKE and BROIL manifolds BOTH light when preheating, to reduce the warm up time. Once the desired temperature is reached the manifold not in use, will shut off.

In any case, on a gas range, the burners for the BAKE and BROIL manifolds use an electric glow bar type igniter. There's a separate igniter for EACH burner. When you make a bake or broil selection on your oven control, the respective igniter begins to glow. After the igniter reaches a certain current potential, the gas safety valve is opened, gas flows to the manifold, and voila! You have ignition. It can take as long as 90 seconds for the burner to ignite. What can happen over time, is the igniter becomes weak or fails. If the igniter becomes weak, it will still glow, but it never reaches the desired current potential to open the gas safety valve. The result: you end up with an igniter glowing with no ignition. And, if you're like me, you're left scratching your head wondering why the thing isn't working when it "looks" like it is. You can easily tell if the igniter is working by opening your oven door and selecting bake. Watch the oven pan in the bottom of the oven. You should see an orange glow coming from under it. It here's no glow at all, the igniter has probably failed. If there IS a glow, a current reading will tell if it's within tolerance. The following link explains more on these igniters and how to replace one:

The bake igniter is a common fail item as it gets used more frequently than the broil function. On your range both igniters are interchangeable. You can purchase replacements on line at searspartsdirect.com, repairclinic.com, or appliancepartspros.com. The part number is WB2X9154. Shop all three sites for the best price.

I hope this helps you. If my assessment of your symptoms is wrong, or if you need further assistance, please let me know.

BBQ Galore Capt'n Cook 4 burner gas grill won't get hot.


Most modern gas regulators have a safety feature to prevent gas left on. If you shut off the tank first and then turn off the burners, it will trigger and keep the gas flow at a very reduce flow to prevent you from turning on the tank again with the burners left on and not realizing it. Turn everything off and then turn on tank first, followed by the burners and this will solve most problems of a low flame or a bbq that won't get hot.

Gas Dryer won't stay hot


There is a thermoelectric eye that says it is OK to keep the gas burner on. If this sensor is defective or blocked from "seeing" the gas flame is properly lit, it will turn off the gas flow (safety) override solenoid. With the unit unplugged make sure that the optical path on the upper right (1:30 CW position) flame tube inside sensor window is clean. The rattle you hear is probably the safety gas shut-off solenoid engaging. If you need more help, please ask -- SWT

EUROLEC 3572 9506 LPG GAS OVEN


OK sista62, here is your solution. The problem is that the thermocouple that controls the valve supplying gas to the ovenjet is not working. A new thermocouple is available from http://blgas.com.au/online/category4_1.htm and will cost about AUD$40.00.


The control valve is located right behind the knob on the frontpanel (the centre one that controls both the oven and the grill.) You will see two small copper tubes going into the control valve. These are the thermocouple tubes, one comes from the griller and the other from the ovenjet. All the other knobs only have one thermocouple for each of the topplate burners.

If you want to test before you buy, disconnect the thermocouple from from one of the topplate burners and connect it to the one for the oven control valve. Now turn on the topplate burner and keep it going by holding the knob down on the front panel for this burner. Now light the oven burner and it should stay on.

Good luck.
