Propane heater I have a wall mounted vent free propane heater. It will light and fire but once running it will only run about two mons. There is no odor. I did vaccume it. I has sat all summer with pilot off. I thought cleaning was the issue but it still does not continue to run. Any help would be appreciated. Thanks, Kathleen

Re: propane heater

I recently had a similar problem with my DESA wall-mounted vent-free natural gas heater. We had it repaired but the problem recurred annually until it wouldn't stay on, even on low. There is a part known as an oxygen depletion sensor (sometimes called a flame sensor) that is part of the pilot assembly. When it is working properly, it sends a very tiny current that lets the heater know to keep feeding gas. After a few years the sensor can get rusty, which interferes with its electrical job, causing it to tell the heater to shut off so it doesn't kill you. A temporary repair can be effected by removing the part and cleaning it with sandpaper or emery paper. I suppose compressed air might work too but probably not for long if it is impeded by rust and not just dust. I found all this out from the repairman who thought he had it fixed and then it went out as he was leaving. He couldn't find the part but I found it online at a DESA-authorized distributor and it was about $40. He installed it in about 10 minutes and it has now worked like new (it's at least 15 years old) for over a month.

Re: propane heater

I use canned air and it solves the problem for a while. Shut it off and then spray that where the pilot light is. Wait a little while and turn it back on. Every once in a while you have to clean it out too. I use the canned air at least once every two weeks or mine does what you describe.

Re: propane heater

Make sure that the pilot assy is clean... really clean and rust free. A small wire brush and a toothbrush are two really great tools to use to get that baby clean. If that doesn't do the trick, something else must be wrong and will need to go to the pro's for repair.

You need to clean it out. Take the wall heater down and use a air compressor to clean out the gas system. Also clean the orifice out. Make sure that the chamber is clean and clear of spider webs and dust.

The propane may have a higher sulfur content; however, the odor may go away soon. It is probably caused by the dust and oxidation (micro-rust) that attached itself to every part of the heater while in storage, even though it was "sealed".

Once you turn the gas off, be sure to unplug it if your model has one. While you do this you should also clean the inside with a light brush and shop vac.
