heater cooker will not light

Question

mnguy152

sat night was out fishing. Heater was working fine ran thru one bottle of gas switch to a new one. Hit the red button to start it and nothing . Grab my 5 pounder and hooked it up and still nothing. So yesterday I took the heater apart and cleaned it up tried it again and still nothing. I did notice that the red button had a crack in it but when it was apart it was still pushing the switch . So my question is could it be the red button bad or is it something else i missed. I did clean it up with brake cleaner (all i had at the timeand a can of air. And the 5 pounder and 1 pounder did have gas in it. thanks

If you are sure that nothing got bent on the cooker end of the connection it might be your thermocouple. The red button is what allows gas to get by the thermocouple so you have a pilot and that in turn should heat up the thermocouple and allow gas to get through. I am second guessing myself and now wonder if the red button is the culprit.You could always heat the end of the thermocouple and when it is hot turn on the heater to low and see if it lights and if it dose your red switch is bad. Just a few things to try.

You should still be able to light it even with a bad thermocouple, if the thermocouple is bad it just will not stay lit once you let go of the starter pilot button. Do you hear or smell gas when you push the button, remembering that you have to turn the gas dial at least to the first heat setting first? I have had about 4 of these heaters and had to replace just about every valve part at one time or another. One time I had the gas heat setting valve break on the inside and didn't even know it until I took it apart and found the valve stem broke inside! Are any of your tanks brand new? I also one time learned the hard way after running all the way to LOW that new tanks must be purged of the air they have in them when their shipped, or the gas will not light! Cold trip! frown You maybe able to get a new gas valve assembly at fleet or a gas company that services them?

Go the mr. heater website and you can get all the parts you need. I got a thermocouple for $8 bucks this week. But Leech is right, it will still light if that's what's bad but won't stay lit.

Before you waste money on a t.c. take the unit apart again. Seperate the valve from the tube that runs down to the element. On the bottom of the valve is a little pass thru nipple. remove that and poke it through with a pin. This has happened to mine several times. What happens is from bouncing arount the excess thread sealant breaks up and ends up down in the bottom of the orifice. Hope this solves your problem. Another tip. Use some plumbers grease on all moving parts before you reassemble the unit.

Hey guys found out what happened with the heater. The nipple part that screws into the tank came off when I change tanks went out fishing the other day and went to throw the old one out and saw something diffent . come to find out it was the nipple from my heater. I took it out of the tank andput it back on the heater and fired it up just like new. Thanks to all the guys that helped out your the best.

      Any updates as to the slush conditions on Vermilion, particularly off the staked trails?

      Yeah I tried the wrench yesterday. I Can't get it to move with a load on it. With no load on the jack it does go up and down with the electric motor though. I ended up ordering a whole new jack since they're only $200. This one I'll take apart and try to fix it and keep it as a spare.

      Was out checking ice.....on west side....even though there is good ice closer to shore, when neighbor was trying to plow a road out farther, a lot of water was coming out of a crack. Please do not go out with a larger truck!!!!!

      I'm also thinking about going up this weekend. We were thinking about Barnacles or Red Door. It will be our first time out of either resorts. Any recommendation or opinions about the resorts and their roads? Thanks in advance!

      Thank you.. and thanks for the advise on the Duluth forum! I will look that up and subscribe.

      Thanks for your response! Sounds like fishing is pretty much the same on this end as Ontonagon. Aside from the rock reefs and possibility of snags on the bottom. I don't run lead core but have a pair of downriggers and some dipsies. I fish a lot on the surface with my Otter Boats with Rapalas and some spoons. I always run at least one dodger or flasher in the mix with a Howie's fly or a spin n glo behind it. Thanks again for your input! I appreciate it! Hopefully I can have a good weekend fishing!

      Glad your back Bryan! So far my season hasn't been one for the books but it haven’t been horrible. I’ve been waiting for your videos good to see your back man!
    • JohnnyM
      Thanks for the input!  I definitely don't want to snag one of my rigger weights! I have otter boats I run off a mast on both side of the boat. I run surface spoons and stick baits off the lines. Works well out of Ontonagon and sounds like it will work here also. I have a few dipsies also but do not have lead core on any of my set ups. I run a flasher or dodger on one of my lines also. Usually on one of my dipsies. I pretty much sounds like fishing off Ontonagon except for the snags on the bottom of the north shore. Thanks for your wisdom! I appreciate it!

      I drove by the lake this weekend and saw a large amount of vehicles and houses out there.  We are finding the crappies either out deep in the holes suspended or they are hugging weeds.  I know huge difference but don't be afraid to go shallow or deep.  I wasn't too far from Crystal fishing 6 feet of water Saturday fishing cabbage and getting a mixed bag of panfish, pike, and bass coming through.
