Ok folks. I have talked with several of my OLD SCHOOL fellow RV'ers, and Decided to post a blog on Gas fridges.
(Im relaxing before a long haul).
Ok, here goes.
The number one problem the Old Skoolerz,(as we are called) have seemed to notice over the years is Auto ignition, (peizo ignition).
Case in point,, Ole Frankie,(our senior member in the close knit group), had a problem with his Auto ignition clicking ON,even when switched over to full electric. He would hear that ole click,click,click,click, as if the igniter was trying to light. For an old guy who is older then dirt, he has some good hearing. He went in to investigate. He says Sure Nuff, its a clicking, and under close observation he noticed the pilot light *trying to light.
With a gas regulator, NO gas is supposed to pass thru the valve assembly without the Thermocoupler being at set temp, therefore allowing gas to pas through the valving. He watched it for a bit,(laying on the floor he decided hes gonna be there awhile). He watched the pilot light nozzle spurting a little yellow flame,, *trying to ignite.
Each time it Clicked, a small short burst of yellow flame would come out. That is NOT supposed to happen.
OK,, Pay attention now. DO NOT ATTEMPT THIS.
Frankie took his BBQ lighter and slid it into the firebox (after he took the inspection glass out), and flicked his bic, so to speak.
Frankie lost his eyebrows and part of his mustache.
Now Ole Frankie is in his 90's (like I said,, hes an old timer).
He jumped back and put his eyebrows out and realized his FIREBOX was filling up with gas, from the valve assembly, allowing gas to pass through. Now Ole Frankie says,, THAT IS NOT A GOOD THING AT ALL. He calls his fellow Rv'ers and asks what the problem mite be?
(Its pretty obvious,,bad gas regulator). Everyone he called verified that.
Frankies regulator was approx 4 yrs old,and it was failing.
Frankie had a youn ac/heating guy who does residential home installs and maintenance come out and look at it,, The young guy spent about 10 minutes checking the system out and verified the gas regulator was failing and installed a new one. He then used sudsy soap at all the connections of the gas line to verify no leaks.
He mentioned to observe the following,,,,,,,
If your fridge makes clicking sounds while ON ELECTRIC only,,, Shut it down completley and turn off Gas at the tank and let, the rig air out, with windows and door open. Check the back of your fridge (thru the access door on the outside), and see if the pilot light is trying to light.
Ive called a few RV repair centers around Waco,Austin and San Antonio and they have said, Gas regulators do go bad and its mostly due to NOT being used, and mother nature takes its toll, with corrosion etc. Especially with moisture IN THE PROPANE itself which causes corrosion inside the regulator valve assembly. Thus causing gas to leak through, and eventually into the fire box.
The same goes with gas furnaces, The fire box being a large or small one. Fridges have a smaller, so called fire box, but it doesnt take much to accumilate enough *gas, to cause a major problem.
Forgot to mention,, Gas water heaters has same concept,,
Gas appliances have a so called fire box to isolate the heat to a specific area and they all have regulators. Some have manual light and auto (peizo) lighting.
So as you do your maintenance checks,, Check your gas appliances on full electric (if you have the dual option of gas/electric). and listen for the auto ignition and see if its *trying to light.
Some RV manufactures are installing Electric ONLY appliances in their new RV lines, thus avoiding issues with gas.
They have even upgraded with better battery banks,inverters and gensets.
Hope this info helps .........
