Heater issue...

[&JAG]

I have a sunflower/cooker heater with a 5' hose connected to the propane cylinder. I just replaced the thermal coupler and now I cannot get it to stay going after I let off the starter trigger. Where as usually it will go after the sunflower gets mostly red. Any ideas?

Make sure the tip of the thermocoupler is far enough the flame. Bought a used sunflower type used and it wouldn'd stay lit. Moved tip further into the flame and problem solved. Hope this helps

I tried that but, it seems to flutter and flame out like it's dirty. Any ideas about cleaning the inner workings maybe?

Tape the starter trigger open. It's probably not recommended, but I've seen people run them that way for years.

I would try replacing the thermal coupler as opposed to taping the starter switch open. That is probably better than bypassing safety features on a gas appliance.

Sounds like the thermocoupler you got is not doing its job. Not a lot going on in a Mr. Heater. I would keep looking at the coupler, maybe try another one. Its hard to tell what is wrong but if you asked me what to do without saying that you replaced it already I would have told you that it was you thermocoupler.

make sure the "TIP" of the thermocouple is in the hottest part of the flame
