No LP to the stove top.

Remember it is left-handed thread going into valve!
By the looks of it, I would be looking for a new one.

OMG, that is tight! Regulator and solenoid are too close to the tank to unscrew. Shot a little wd-40 on it and tapped it a little bit. I'll come back later I've got something else to work on.

Those detectors have a life span, and should be replaced, I think its like 8 years mine has a "replace by" date on it.

Yes, there is a manual valve on the tank.

After turning on the detector, I opened the manual valve and tried to light the pilot on the stove top. After a minute I turned the gas off.

I was hoping to hear the solenoid click when turning the power off/on on the detector but did not hear or feel anything.

I like the idea of removing the solenoid and getting a new sniffer.

Let's see how that goes.

I had a similar propane problem on my RV. In my case the first "appliance" to fail was my propane generator - it would start, run a few seconds and then die. The other appliances seemed to work fine. Isolated it to the propane regulator which I replaced and that fixed things.

While trying to figure out the problem I did quite a bit of research and discovered that there is some oil added to propane. Sometimes the propane supplier overdoes the oil addition. Over time the oil tends to collect in the regulator and gum it up reducing supply to appliances. The first ones to show problem are those which are higher users of the gas supply, such as my generator. But in time everything using propane can show signs of failure or cease to work all together.

Appliances that utilize propane are at times difficult to fire up, particularly when propane supply has been turned off for extended periods of time. Under this scenario in many cases air needs to be purged from LP supply lines before appliances will ignite. After turning on propane at tank, I turn burners on let air in lines purge lighting stove when I detect propane coming from burners, doesn't take long.

Is the Manuel valve at the tank on?

There is a solenoid on the propane tank that is energized by the detector. The detector maybe bad. Most rigs do not have them.
You could remove the solenoid, get a stand-alone propane detector.

BTW, this is the first test of the LP. I figured the stove top is the simplest item. After this I will be testing the furnace, water heater and fridge.

Just having way too much fun!
