Pilot light

Yes I have some vent free gas logs and the problem is the pilot light keeps going out and you have to relite it.And sometimes It goes out when it is burning the flames and the flames and pilot will go completely out. I have trid cleaning the pilot but that has not work and this is a propane unit. Thanks for any help Steve

Hello: Steve

Gas logs that have a remote or built-in on and off switch use a pilot generator to produce the DC current needed to operate.
With that in mind, the generator is the most likely part that needs to be replaced.

Below is an excerpt from a prior posting which explains the pilot generator, etc.

Another type of safety device used on heating appliances is a pilot generator. The element end on this part looks similar to that of a thermocouple, except the element end is larger.

A pilot generator can be identified as, usually but not always, having two wire leads. These wires leads, are usually attached directly to the body of the gas valve with small screws. The pilot generators wires can also be attached to a reset device not directly located on the gas valves main body part.

Mentioned below are several other possibilities that may apply.

The pilot flame must be all blue in color. There should not be any yellow color in the pilots flame. The flame should be the correct size to both provide enough heat to the thermocouple or pilot generator and also provide a positive source of ignition for the gas.

It's also possible the magneto head contained within the body of the gas valve or other reset device is defective. The magneto head is the part the thermocouple threads into. The magneto part may or may not be individually removable and replaceable on all types of gas valves or remotely located safety devices.

Some newer model gas logs also have a heat sensitive safety device located at the top near the flue. If too much heat is sensed, the device will shut off the entire system to prevent the fumes from entering the inside of the room.

Most likely but not always, simply replacing the safety element Pilot Generator resolves the problem.
