We have confirmed the tank is full - it only took 4 gals after 4 months of only using it for the range. Gauge reads full as well.

Turn the switch on, light comes on, burner lights.

Burner stays lit for maybe 5 minutes, then goes out. Check light at switch and it is turned off.

It will turn on again, repeat 5 mins then off.

I understood if there was a leak the leak detector would prevent it from coming on at all. Perhaps I have that wrong?

Please advise. Thanks much,

The thermocouple for the pilot lite may be dirty or need to be moved farther into the flame.

If you have other gas appliances do they work?

He used the stove on gas for 4 months.
I think this is strictly a HWH issue

If you had a leak and detector senses gas it should make noise.

If issue started when tank filled then check for loose wire as it may have been bumped when tank filled.

Get a voltmeter and check voltage at valve and senser.

Before doing anything, open access door and see if it runs any longer. Could be lack of oxygen. If it doesn't run longer start trouble shooting as in owners manual.

I'm guessing we are talking about the water heater? And that other gas appliances work? If so, a couple observations apply:

1. The water heater is his Tuscany has no pilot light - it is DSI (spark ignition)
2. The LP supply, regulator, etc. are fine No need to look there.
3. The LP detector will NOT shut off the gas supply - it is an alarm only.

If the check light at the heater LP switch stays off, the heater circuit board has to be a suspect. If the heater shut itself down, or if the flame went out for some external reason, the controller should detect "no flame" and close the gas valve and turn on the check light. Does the light come on for a few seconds during the initial ignition (when the switch is turned on)? Just trying to make sure the light is working properly...

Can't tell of you are referring to hot water or fridge. Mine did this recently with the fridge and it was the thermocouple not seeing that the flame ever lit so the ignition kept firing. Cleaned the contacts and it works fine.

They all have thermocouples, right? No burner, no heat, no go.

Make sure the valve on the propane tank is turned fully on. They turned it off when they serviced it and may not have turned it fully on.

Cheers!

The only thing we run on propane is the range. The issue was that after only five minutes the burner would shut off and the propane light at the switch would go out.

It happened before the four gallons was added and did it again afterwards.

After not doing anything, I tried it this morning, cooked breakfast without the burners shutting off. The propane light stayed lit for several hours.

Seems to have resolved itself - or perhaps it was the all the help folks sent our way

.

We will have it checked out during our maintenance appointment in November.

Thanks again everyone!

Jodee,
Have your lp pressure checked. 2 years ago we were having problems with our furnace cutting off in the middle of the night. All other lp devices worked normally. The technician rebuilt the furnace, replaced the thermostat, and replaced the control board. None of this worked. Finally, he checked the gas pressure. It was only 8 inches on the manometer. He replaced the regulator and it's fixed.

Gary RVRoamer · 09-28-2015, 08:49 PM

Faulty regulator could do that, or globules of oil in the LP pipes/hoses, causing intermittent interruptions in gas flow. Sometimes moisture has condensed in an LP tank, or an excessive amount of mercaptan oil (the stuff that give it the "gas smell") builds up in the tank and gets pushed through the plumbing into the appliances. Cleaning out the lines, or maybe the tank itself, may be indicated.
