but last time I try to use it again doesn't work start working for like 50 sec and then just stop but no heat.

Also sometimes the electric converter is making a large bip and the lights turn off but no the tv.

Any ideas?

Thanks for the help.

How's your battery? The TV is 110v but the lights and furnace blower/igniter are 12v. Sounds like a weak battery, maybe?

Have you refilled the propane tanks since your last post? If so, then you will need to purge the gas lines again. Remember, this purge cycle MUST be done every time the gas is either shut off or a gas bottle replaced. If the gas is off for more than about 10-15 minutes it will escape and air will enter the lines again.

Is conected to my house source is 120.

The converter still had to convert the power from 120 to 12 and the battery, usually still needs a good charge to make things work better. I'm no expert, but have read many posts similar and the battery was the culprit.
Might be worth a check

I didn't use the travel trailer for a week so I think this ^ can be the problem.

This sound right I was thinking the same but this is my first travel trailer so I ask before I burn it. thanks

We purchased a new 2011 Sierra 340RL in October and have had a few issues with the furnace. The first night (Friday) we camped in it the furnace stopped about 1:30 AM. I shut it off for a few minutes and turned it back on and we had heat the rest of the weekend. We camped again the following weekend with no problems. We camped again Thanksgiving weekend and again woke up in the wee hours of the morning with no heat. I check and the first propane tank was empty; I switched to the 2nd tank and purged the lines, but still no heat. I replaced the empty tank with a full spare I keep (and purged the lines again) and still no heat. We used an electric heater and went back to bed. I called a local RV Mobile tech and as luck would have it he was camping 12 sites away in the same campground. He explained that the “low pressure diaphragm” can stick. He tapped on it and we had heat the next 3 days. I only wish I would have crawled in and watched what he tapped on. He said this is a common problem. Just curious if anyone else has heard of this?
