Mr. Heater issues

11 posts in this topic

I have a Mr. Heater cooker for a fishhouse heater. I store the heater in a nice and dry area every summer, but when winter rolls around I go to fire it up and it won't work properly. It spits, sputters and eventually dies. It's not the easy thermocoupler fix..

It appears the propane stuck inside the valves, thermocoupler and jet turns to gel and the entire thing is junk. I usually run the gas out by turning the tank off first, but I still have this issue.

Has anyone seen this or successfully cleaned it to work again? I've disassembled and cleaned it and it's toast. I love these heaters, but hate buying a new one every year.

Chuck a good cleaning should get it going again. Did you clean the orifice out?

The gel. Unregulated(high pressure)propane will leech oil from the hose. The hose designed for Mr Heaters is supposed to be resistant to that but it can still happen. If this is a hose you made, get rid of it. After every use turn the valve off at the tank and allow the heater to burn out. Also is this a tank you own? I've seen tanks build up a greasy goo. Before the OPD vavle and when the tank was empty you could tip it upside down and drain that crud out.

Chuck I don't have a answer to your problem and that is because I have a cooker that I use maybe 3 or 4 times a winter and give it no special care and it works like a champ. Do you run this off 1 pond tanks or a 20 pound ? The only reason I ask is that there have been problems with the Buddy's running off a high pressure hose without a inline filter and if the goo you are finding is actually a oily sludge. Have you tried to adjust your thermocouple just to see if it got bumped and might be too close or too far away ?

The hose is a Mr. Heater brand hose, the tank is fresh propane 20lb tank. I used the hose/propane tank this summer and fall extensively with a portable BBQ and Buddy Heater. I know there was no gunk in the hose or the tank.

This must have been propane stuck inside the heater itself, inside the "pipes" somehow.

I bought a new heater and I guess it's just a bad omen hanging over my heaters. wink

I had problems with mine flaming a little this year and wouldnt glow on the bottom last year. seemed like the grill was bad or something. I took it apart the other day and the orifice was getting clogged with soot. a little carb clean and a little air to er, she's good to go. runs like day 1

No flaming issues. No bugs.

The problem lies inside, with the way the gas moves in from the connection nozzle all the way to the pilot jet that dispurses gas into the chamber.

The heater spits, sputters and dies. I can hear sounds that it's working hard to push gas through, and gives up.

Carb cleaner didn't work. I already disassembled the darn thing and cleaned...

I tried it again and this time where the hose connects to the heater and (on/off-low, medium, high knob) it frosted up nicely. Definitely a problem I wish I could figure out.

Did you just have the tank filled? Sounds like liquid propane is getting to the heater?

I thought of that, but the tank is about 2/3 full and I've been using it without problems with the tank and hose.

I already tried a 1 lb propane tank attached. Same thing problem arises.

    • Probably  Canadian. Appears some zealous border guards kept the rest pf them out.
    • my bird id book says its a spotted towhee,used to be called a rufus sided towhee.  
    • Never claimed they were rocket scientists, and I did say they are terrible at putting garbage in containers. Words are all spelled right, just don't make much sense--must be from over seas.
    • You are right. But there was a whole lot of head scratching from the rest of us.  Here is a tasty sample. Thought I'd put it out here for ya just so you do not think your side is hoarding all the genius.  
    • Yea, highly doubt the calls were for well wishes and almost assuredly  illegal at the time, but doubt anything will be able to be proved. Number and length of calls along with a "no no" will probably be the only thing coming out of the Senate inquiry. Am sure Flynn and if whomever else will be well versed on a non incriminating reply. Hard to take down any high ranking gubmint official, no matter the party. 
    • I can't wait for the hearings.  Lock those filthy pigs up!  Send em all to gitmo, heard they have plenty of room there. So how did all that russian propaganda end up on the dnc server?  Youve got 50 pages of hard evidence for that i bet.
    • Reddit I believe   https://www.reddit.com/r/politics/comments/5i63d1/40_electoral_college_members_demand_briefing_on/db5or6d/?st=iy9h32qk&sh=3f2619dd   There were plenty of criminal things the Clinton team could have been charged with but when the inmates run the asylum the usual rules don't apply.
    • Hillary and DWS didn't commit any crimes as difficult as that is to believe. Sketchy politics certainly, but what happens within a political party has no legal ramifications. The FBI already cleared Clinton of wrongdoing with regards to the email.   Flynn and other members of Trump's team are likely in violation of the Logan Act.
    • Well, if that happens then let the chips fall but do you think they will be arresting Hillary and DWS at the same time? If so it would be a good start.
