double sunflower head issues

[Boar]

worked in my garage while insuletaing and sheet rocking up u til day befor this weekend, i disconected it from the tank, put it in the back of the truck.for the weekend of ice fishing, used the big house, not the sunflower, i get home wanna heat my garage for a bit, both head wont stay lit, odds of both thermocupler goi g out?? any sugestions??

[glenn57]

go buy something better then a sunflower!!!!!!! them suck!!!!!

Odds are from inside to outside it now has moisture somewhere in the lines. Thermocouple doesn't normally "just stop" working. Blow out lines and heat heads first. 

[Boar]

the main fuel line from were it scres into the tank and the channel to the head?

I would think Reb is right.
But I would check the connections where the thermocouples come together as well.

[Rebel SS]

Yup. Metering orfice in valve head could have tad of moisture in it.  Clean head; it  (valve) and thermocouple with q-tip and rubbing alcohol. Bet it'll fire right up. Worked on a lot of these. (Make sure ya blow out any "fuzzies" from Qtips!)

[Boar]

cool thanks reby!!

[Rebel SS]

Let us know if that works.  Forgot to add make sure ya blow ceramic heat elements out, too. They do get a lot of dust in them.

[Boar]

blew up threw the neck, puff of sheet rock dust came out, did the other and a ljttle.came.out,  tue head with the bigger puff is worki g the other not, needs a little more attention i think.

Glenn's?    Does yer heater have the double tip switch on it?

[Boar]

[mike89]

hey Boar if ya can't get it going I have one..  If we can make it work I' d give a dang good deal...  just got to figure how to get it to ya..

[Rebel SS]

Well, some sunflowers DO have the tip switch.......have you tried cleaning the thermocouple tip off with EMERY cloth? You blew out the gas valve, right? The gas line; ie, no obstruction?
Turn on the gas, give it a second, and see if ya can smell the gas from that heads ceramic grid....if not, then the gas isn't making it that far. Bad valve, line, or goo somewhere....last resort, swap the thermocouples around...if that don't do it, ya got a one-headed sunflower!!!!

[Boar]

gas makes it to the head, i depress plunger gas is eminating, poof it lights, i hold for even up to 30.seconds, till head is yellow glowing, and tip of thermocupler is hot, i release and out it gose.

[glenn57]

Like I said get rid if that sunflower, buy a decent heater. Sunflower heater suck.

[Boar]

I have a single burner sunflower that does the same thing.

The thermocouple actually creates a bit of electrical current, which then keeps gas valve open......I'd guess that thermocouple, or wire to it is broken, or valve is closing back up. (Obviously) Might be time to chuck it, depending on how much ya wanna tear it apart and put into it..................
