Propane stove question

[Stonew98]

Am renovating an 85, put in a new two burner propane stove. Had AS dealer install new propane tanks and regulator, I'm only using has for this stove and furnace (not fridge and oven).

Issue is...when I switch on the gas...The stove will light just for a second, then shut off...so I assume gas is not flowing correctly (yes tanks are full).

Is this a regulator problem?

Thanks!

Are you holding the knob in long enough to heat the thermocoupler? It is designed to shut off until it is heated. A safety feature to stop unlit gas.

If you are holding long enough and it still shuts off, it could be a bad or misaligned thermo coupler. The fact that it lights at all shows some gas is flowing.

Many possible causes. Yes, it could be a bad regulator.

But first, check to see whether the regulator is showing red on the empty tank indicator. If it is, it is possible that the excess flow shutoff valve has tripped on the connections to your propane tanks. It may help matters to close the tank valves, wait a minute or so, and then reopen them slowly.

If the indicator is green then your problem is likely to be with the regulator or piping.

So here's the thing...if i stick my ear down by the stove I can hear the gas for two seconds then it does, just like the flame. Doesn't appear to be anyway to adjust the thermocouples on my stove...even if I use a lighter and heat up the thermocouple real good the same thing happens.

...and now the furnace doesn't light...hmmm...

I had a similar problem with a stove. It would light briefly then go out. Wait a while, try again, and get the same results. Turns out I had a blockage in the line between the regulator and the appliance. Some gas could pass the blockage slowly and re-pressurize the line to the stove over time. I cured the problem by disconnecting the propane line downstream of the regulator and at the stove, then used compressed air to blow the line out from the stove to the front of the trailer. Blew a dead insect out of the line. Then reconnected the lines. Everything worked after that. A crushed propane line could possibly cause the same results.

I am "bench testing" my appliances and was able to get a regulator and short hose with the proper fitting (3/8" flare in my case) on it to connect a propane tank directly to the appliances for $15 at my local hardware store. It is a gas grill accessory. This allows me to test the appliance with all of the other distribution out of the system.

Also, a simple pressure test gauge could help you solve your mystery.
