So could someone give me there opinion on our stove output, our refrigerator does not stay cold on gas, but works fine on ac. I think the regulator is running lower than it should, do , what do you think?

Think the only way to know is to measure the gas pressure,borrow or buy a ounce gage and measure.

You probably have a bad fridge, turn off every thing else and check it again. Have a great day. ---- Fritz

Make sure the gas burner in the fridge is clean and free of any rust bits. A low flame can produce insufficient heat.

Can the stove run both burners without one side dimming when the other is lit?
If so the pressure may be low ,

Roger first photo is fridge. I removed and verified being clean inside. The regulator has been pressured last ten years, no leaks. Just think the output looked visually low. Just thought someone might look at range photo and say yes mine looks the same or I'm guessing bigger I'll replace the regulator because they do get Old before I attempt to measure flo

I read where regulators should be changed every 5 years or at least fully tested

Wonder if this is it:

If NOT the pressure may be low

BTW, for under $25, just replace the regulator!

Our U300's regulator started to smell so I replaced it. Foretravel installed single stage regulators OEM but a 2 stage is only a dollar or so more. It's slightly longer so I added a support so it would not vibrate.

Yes, easy to check the regulator's output pressure. They do get old.

It's not the fridge. Electricity heats an element that heats the same ammonia the gas does.

The "chimney" of the fridge over the burner/flame is where the heat transfer occurs. They frequently build up rust flakes that inhibit the heat transfer.

You can "bang" the chimney and knock some rust loose, but learn how first so you don't punch a hole in it. there is a method.

My stove burners were low so I decided to change dual regulator with new one. When I unhooked the rubber line off the regulator it had substantial amount of oil in it. After draining oil and replacing regulator the burners flame was much higher. Also my furnaces were not lighting every time since finding oil in line they both light every time.

Flames APPEAR normal. Dinosaur electronics makes a replacement board for the refer. My igniter went out on my 97 dometic rm 7832. Fixed.

Currently running 23 and 50deg on gas. Will run -14 and 34 on ac. Propane should be more efficient if it's getting enough BTUs to operate Will locate a brush today and clean the flue

Check the height and color of the flame. Here is what your flame color should look like: Appliance411 FAQ: What should my gas range's flames look like?

Pierce the trouble shooting aid is helpful. In looking at the first post with pictures I do believe the old regulator is the primary cause of my poor gas performance.. works good on ac even when 105 deg outside. I will order a two stage regulator when we get home on Tuesday

Be sure to order the CORRECT regulator.

If installed vertically, the vent (small screened area) must be on the long axis of the regulator.

If installed horizontally, the vent must be perpendicular to the long axis of the regulator.

Said another way, the vent MUST POINT DOWN when installed.

Minor suggestion: NEVER check your old regulator for leaks with a lit match.

I think our two stage regulator was $21-$25. About a buck or two more than the single stage.

If anyone is having trouble with higher pressure air not making bubbles when they check for leaks, buy some Pustefix bubble making liquid. It's what is used in the bubble making machines and not only makes huge bubbles but you can touch them without popping them plus they last a long time. Used in weddings, parties, and Foretravel air leak detection. Amazon.com: Pustefix Bubbles with Wand (Colors May Vary): Toys & Games

Looked at the flame in the two photos at the top. Color and size look good but nothing like checking the WC.

When I was a kid in HS, I had a go kart gas tank with a lot of rust. I used acid to get rid of the rust and then I wanted to see inside so lit a match and tried to look inside at the same time. I got my eyes closed just as the flame hit my face. Didn't have to worry about a hair cut or sideburns for a while. Terrible smell of burning hair.

Replaced gas regulator with new. Same two stage 290 has been replaced with 291 $35.40
Amazon.com: Marshall Excelsior MEGR-291 Reg 2-Stage Vert: Automotive
Somewhat better but still unacceptable 14deg and 47deg on max setting
Works perfect on AC power. -4deg and 34deg on setting 2
I would think if it works okay on AC gas should be better?
Does the control board function differently between the two?
I do not see as hi boiler temperature and the fans never come on with gas. I have visually checked flue and cleaned, very little rust deposits removed. I have visually checked propane jet and it's clean, I didn't clean with solvent but may go back and clean. Flame is same as posted prior on fridge.
I was really hoping my old regulator had low output and was my problem but nothing much has changed.

You can clean the burner and also the orfice. Also check the swirler in the chimney to make sure that it is there and not partially burned off.

YUP, do a "burner area tune-up. No parts needed and no special tools. Can make a world of difference in BTU's of heat to the boiler= difference in cooling
