Anyone know anything about forced air propane heaters?

Thread from 2012:

My heater won't stay lit. According to the directions, to start it you turn the knob to low, push the knob in and hold it in and it should light, hold the knob in for 30 seconds and when you let go it should stay lit. Even when it was brand new it would usually go out unless I held the knob in for a minute or so. I don't think I ever had it stay lit after the 30 seconds they talk about in the directions. Since it was cold last night I dug it out and tried to use it. It lit just like it's supposed to, but went right back out as soon as I let go of the knob. I thought maybe since it's been sitting for a while I'd hold the knob in for an extended amount of time to make sure it really blew or burnt any old crap that may be in it, so I propped a wheel against the knob. After about 15 minutes of running, I took the wheel off and it immediately went out. Any ideas? It looks pretty much like this one:

It sounds like a bad thermocouple. The thermocouple shuts the gas off if you lose flame in normal operation. Sounds like yours is TU as you are on bypass when you hold the button in.

This, or the controller.

I like the kerosene heaters for this reason, they just work.

Good call. I've never had one of these apart, so I don't know exactly how they work. I didn't realize they had a thremocouple. Are they usually a standard unit, like on a furnace or water heater? Oh, by they way, I checked now that I'm home and mine is a Reddy Heater RM100LP, like this one

If it hasn't been working since 2012, he's probably frozen by now.
