Gas keeps switching off after a few minutes

I have a Rinnae gas log fire. It is a bit difficult to get going. Once going the gas switches off after a few minutes. If switched on to all three burners then all flames struggle to keep lit, like the pressure is not enough.

Hi!!

Make sure you have the gas supply valve open all the way. If it is, you may need to replace the thermocouple (if equipped) or the thermostat unit.

The thermocouple is is the skinny copper tubing that should be screwed to the thermostat and the other end is warmed by the pilot flame. This part sends the signal to let gas go to burners if they are lit, but in case the flame goes off without shutting the valve or thermostat off, (if wind blows or accidentaly spill something on it) this device inmediatelly send the signal to stop flow of gas, when defective, some times works fine and some times does it erratically. (Same thing does in a gas water heater) It is very common for this device to go out and it is very inexpensive and easy to replace.

All gas units are equipped with some kind of device that does the job of the thermocouple, they may call it something else. But that's the part that may be defective in your unit.

Don't forget to rate this post!! Good Luck!!

Spark IS fire, I guess you mean it HAS spark, but the engine wont run? Make sure the fuel pump "inertia" switch is OK. even slamming a door can trip it off. then you will have NO fuel pressure. Its in the left side, trunk area.

Pilot LIGHT KEEPS GOING OUT OUT


The pilot light jet may have got a little bit of dirt or grit in it which is preventing it from keeping alight. If the pilot light has only a weak flame, the whoosh of the main burner igniting can quite often blow out the pilot. Try probing the jet with a fine piece of wire to see it the blockage can be dislodged. You may have to unscrew the jet to clear it by blowing air through it. Make sure gas is turned off first before removing any parts.

The pilot light also has a thermocouple that allows gas to the pilot light while the flame is burning. If pilot flame goes out for any reason, it shuts the gas off to the pilot jet to prevent unburned gas collecting and causing a safety hazard. The thermocouple is bypassed by a switch during the initial ignition and once the thermocouple warms up after a minute or two of holding in the bypass switch, it should maintain the pilot. If, after cleaning, the pilot light keeps going out, it would seem that your thermocouple is faulty and needs to be replaced.

There is no information on the model number so I'm going to answer this question assuming you have a high efficiency forced draft fireplace.
With fan-forced draft, it is crucial that the inlet and outlet pipes are free and clear.......no obstructions. If the inlet has an obstruction, it can prevent operation when the glass is in place and allow operation with the glass out. There is most likely a pressure switch in the electrical circuit that will detect proper pressure (ensuring proper intake & exhaust) that will prevent operation if proper pressure is not detected. It is rare for the switch to fail; however, it is common to find kinks, cracks, and/or moisture in the air sensing lines........check them kink, cracks, and obstructions.

I hope you find this information to be very helpful to you as a solid jumping off point moving forward.

Let me know if I can be of further assistance to you.
Good Luck in your endeavor! :-)

Gas cooktop starter continues firing


Turn your gas valve on, but leave your unit unplugged for a few days. You can light your burners in the meantime with a lighter so you can cook. Usually this problem is caused by moisture getting into one of your ignitor switches which are under your burner knobs. Most of the time the switch dries out and you can plug your unit back in after a few days. If it still keeps firing then you will have to replace one or more of your ignitor switches. Usually a very difficult job as most gas cooktops are now sealed burner units which means the top of your cooktop is bolted down to the burners with several screws or nuts that heat up with usage and become almost impossible to remove, without having to drill out the screws, or chiseling off the nuts. Be careful of boilovers or cleaning around the knobs with too much water to prevent this from happening again. Also get a surge protector at least 2000 joules or higher to prevent damage to you spark module. Good Luck, Appliance Specialists

Bike only fires once


Okay, let's have a look at it. Say Ahaaa.
The probable cause of the problem is not the spark. Get a fresh set of Stock NGK spark plugs, ground the plus to the engine, and check each cylinder for spark as the starter button is pressed for 3 seconds or so. I will wager that the spark is present.

The likely problem is the fresh gas was put into a very rusty gas tank. Bits of rust now inhabit your carb and are having fun plugging up the carb. Look at the gas valve. With a little luck there is a small bowl behind the valve. Remove it and tell me what you see in the bowl.

Gas log will not stay lit for more than 5 minutes


Sounds like the gas regulator has failed.

There will be sufficient gas flow to light the pilot and get a flame prove, then the main burner lights, you will probably see the pilot flame reduce somewhat, and no longer fully surround the flame prove sensor.

When the unit is relighted, the complete sequence starts all over again.

Have the gas regulator checked and adjusted (if adjustable) or replaced by a qualified technician.

If they ignitors worked properly before you aunt cleaned them, the problem could be with the way they were cleaned and what they were cleaned with. Please tell me how she cleaned them and with what. Also, had she cleaned them before without incurring any problems, or was this the first time she had cleaned them?
