7'*18' V-Nose Cargo Trailer Toy Hauler Conversion

Before and after on the Gas tank.. Everything is ready to test later today after the tank dries well and I connect it up.. if you see a mushroom cloud in the South, you'll know what happened.

The electric element I installed in the gas water heater is working and I have hot water... I hope the LP parts work.


All sanded and primed:

I have the tank installed and the gas lines pressurized. No leaks as far as I can tell.

The Stove works, but the oven does not. The Pilot works, but the gas for the main burner is not turning on. Anyone have any idea how to troubleshoot which valve it is? Both have what look like thermal feedback to them, which I am sure turn things on and off to regulate temperature.

The electric hot water element I retrofit into the tank drain plug is awesome!!! My solar cells via the inverter heated the water up in an hour to a very hot temperature then shut off. As long as I have good sun... propane will only be needed for fast recovery.

Now I am going to hook up the 12VDC to the propane part of the HW heater to see if it works. The stove and HW heater are recovered from a donor camper, so this is the first time I am testing them out.


The tank on the tongue. I re-arrange that when I build the generator box... but for now, it works.




All three burners work well... I have to figure out what is wrong with the oven.




The 110VAC switch for the Hot Water.

When you turn the thermostat on, the pilot flame should extend to heat a thermocouple. That's the safety valve t-couple. After a few minutes, 2-4 min the safety valve should open and give you main flame. So, does pilot flame extend? Does it heat the t-couple bulb? You may need to adjust pilot angle or bulb location to get it in the extended pilot flame where it can get hottest. Also, there is a small chance that regulator is not set for LP. But being as this is and was a RV unit, I would think that's OK. If you need to, take your propane torch and heat the bulb from the safety valve, if it opens valve is probably OK, just not getting it hot. Take a quick look to see if there is a shut off valve on gas line to safety valve. If pilot does not extend when thermostat is turned on, probably a bad thermostat. Also, clocks can trip you up. If it has a timer make sure it is in manual position.

I think the safety valve or thermocouple that should open it is bad.. The flame extends out and the bulb gets red hot. I pulled apart the safety valve assembly and the valve is stuck. I think there is a problem with the electromagnet.. Just going to replace. I made sure I was getting gas down to the input.. Thanks.

The Gas hot water works great... but I am confused. I refurbished this from the donor camper so I do not know how it is suppose to work... but it seems as if when the gas is turned on... it has a small amount coming out of the pilot. When I turn the tank on it fires right up and then when the water is heated up, the higher flame turns off and the standing pilot stays on.. but I thought when I turned the tank off (turn off +12VDC) , the pilot should turn off too? It seems to burn as long as gas is on? Is that normal? Anyone know?

[Padilen]

When you say fires right up are you lighting it or does it have an igniter?
For the oven I had a old never used stove. Because it didn't work! Retired RV guy said there was a known problem with it and took it to fix. Never saw it again

It has an igniter. Lights itself... but then never goes out even when you turn off the power. I have to turn off the gas for the pilot to go out.

I did a little research.. the model I have is a G6A-7E which is an electronic ignition with a standing pilot. Looks like the only way to stop pilot gas flow is to install a shutoff to the water heater itself. One it is lit, it stays lit and keep the water warm... then the main gas will turn on via the thermostat and the electronic ignition spark if needed. Bottom line is that is probably working as intended.

The Oven is another issue. Looks like I cannot get a new valve.. I am going to take it all apart and see if I can figure out what is going on.

[McDave]

Not at all familiar with the RV H2o heater, but I can see the Ignition module there. So, when you turned on tank/valve to htr., then you turned on control? Then ign lit pilot? Then main flame to set temp., cycled off main and pilot still on, turned off 12v, pilot still on. Turned off gas, pilot off. Turned on gas, no flame and no pilot gas?
I think that may be right. I have heard of gas stations that that have signs saying to be sure power to water heater and refrig. is off before pulling up to pumps. You wouldn't want it throwing sparks and gas, then flame in a vapor rich environment. And it's doubtful pilot could be maintained while moving at any speed higher than crawl. But when you stop and control is on asking for heat, click click click...Boom? Also, RV gas refrigs are not 12v or lp. They are 12v or 12v AND lp. They need 12v supply to open gas valve. Pilot will stay lit, but no flame without 12v. Pilot flame not enough boil ammonia so no absorption, just more heat. I don't know how that is relevant to the H2o htr discussion, but I was on a roll, so I went with it. Let's get a make and model and try to find a manual or schematic.

Shoot me that Make and Model of oven. Its Magic Chef right? I may be able to help with that one.

McDave

PS. Some safety valves are diaphragm, not millivolt.

Hi McDave, It is a Magic Chef CLY1611BDH with a 74006333 Safety Valve.. I think it is a Diaphragm type also. Just not sure how the thermocouple activates the valve. It does get hot and I use a butane lighter along with the pilot and it does not turn the gas on. Thanks!

I can't seem to find the valve anywhere (discontinued) .

Thanks.

[McDave]

Wow. That is a tuffy. I'm not sure why it is disc. and all the supersedes are disc., but here is one that is a very common replacement for Whirlpool, Maytag, Magic Chef. Part# 74010590 The thermo length is 20" You'll have to verify input size and may have to be creative with mounting, but really it should work.
Some of those thermo's have air inside that expands pushing in valve, some have mercury doing same thing. My guess is the originals were mercury and that's why disc.
Take a look, this could work.

Well... after wasting a lot of time and taking apart and cleaning the safety valve and adjusting.. I got the flame to come on ... but it only does in Broil mode where the Pilot seems to be the highest on the thermocouple. When I turn it off broil (any temp from warm to 550).. the pilot flame decreases and then the flame eventually goes back out..

I ordered a new safety valve and new pilot assembly for ~$90.00 from two different places since neither place had both. I saw no way to turn up the pilot flame ... but since the pilot was kind of "aged" looking and I think maybe the thermocouple for the safety valve just isn't right.. I am replacing both.

Regardless of the outcome... I learned a lot about gas appliances today researching the problem and learning how the system works... an education is never a waste. :-)

Hopefully this will take care of it.. If not, I spent $90.00 and the good news there is only one more assembly that could be defective..

This is the last thing to fix that doesn't work.. Every other system is up and working including Propane and Electric Hot water... On the Hot water tank.. I think the standing pilot is working as it should and I just need to install a separate gas shutoff for the Hot Water tank. I wonder if they make a 12vdc solenoid type so that I will all be automatic when I flip the switch. I need to investigate that.

[McDave]

Hmmmmm..... That doesn't sound quite right. The safety valve doesn't know the difference between bake/broil. Same burner, Yes? Broil is usually just infinite high so it won't cycle off at hi temp (+500). I don't think I have ever seen a T-stat with 2 different pilot settings. Also, safety valves are either good or not. I'm gonna have to think this one out, but we may be chasing the wrong ghost. I'll consult with Mr. Jameson later and see what we come up with. Gonna need a cigar or 2.

I agree... that is why I am replacing the Pilot.. But OI know the main oven knob has something to do with that also.. but not adjustable... It is the last thing that could be wrong.

flboy, Howdy;

Don, the folks at PPL used to have some videos about Hot Water Heaters and quite a
bit of other stuff. If you can find the Model # and make, have that info handy if you
decide to give them a call.
