Water Heater/Fridge Not Working On Propane

[trigal]

need trouble shooting help on hot water heater and fridge not working on propane but does work on electric. stove works fine on propane.
just need ideas of where to start looking.

[HowieE]

Often when a propane tank has been removed for filling and the shut off valve to that is open air gets into the line. The frig and heater can not purge the air quickly because of the size of the orifice to the burner. Crack the gas line at the gas valve on the frig until you smell gas. Try to light after that.

Not familiar with a 2016 A$. But I would check to see if you have 12 volts DC. It might have something to do with the "store/use" switch.
If you don't have 12 volts DC the circuit boards that control these devices will not function.

Have used fridge since tank was filled with no problem. That's what makes no sense.

As TG said, may be the Battery Disconnect Switch/relay position. When plugged into external power, everything will work. When on battery power the switch must be in the "USE" position for 12 vdc equipment to work.

The water heater and fridge need 12VDC for control when on propane. The propane range needs no electrical power to work.

Why would you want to heat hot water???

[HowieE]

Is there a light on the control panel of the frig and does the ignition light on the hot water heater come on when you attempt to light it. If no you have NO dc power. Check the batteries and the disconnect switch.

Yes will check this weekend. Fresh water pump works. Red light does not come on hot water heater. Store button in use position.

Do the gas burners on the cooktop work consistently?

Check for spider nests in the propane burner tubes. Things can be working fine, spiders get drawn to heat, build nests, then kaputski in a day.

We had them recently. Might have to disassemble a bit. Designs vary.

Good luck!

PS -- AirFor Google search for "spiders nest" --

The red light on the water heater should come on initially and then go out. If it comes back on, the heater was unsuccessful at lighting the burner. If it doesn't come on initially you probably do not have 12 volts at the heater. Check your DC fuse panel (or auto-reset DC breakers if your trailer has those).

OK you have batteries because the pump works. You have gas as you have used the stove.

You now have to see if the frig is getting power. Check the control panel for lights. If none there is an interruption in power, likely a circuit breaker, to the frig and hot water heater. Any 12 volts lights not working?

You may have to get a volt meter to test the circuit breakers.

Fridge has power. Will check circuit breakers on Friday. Thanks!

If the frig has power there is no reason to check the breaker that feeds it.

You may want to look at the fuses on the frig control board.

And check for gas at the frig gas valve by cracking the flared nut at he valve.

In troubleshooting you never assume anything without confirming first.

PS referring to burner tubes of water heater and fridge, not gas range. Previous Google link may reveal threads with similar FC25 problems.

[HowieE]

It is odd that spiders would get in both burner tubes or pilot tubes at the same time but it is something that could be the problem.

If you remove the tubes you have to look very well because those little buggers are small. Another invader are stink bugs.

I agree but it is one of the possibilities moving up the list IMO.

trigal, were you able to check for spider or stink bug nests in the burner tubes of the fridge and water heater?

Have a good weekend!

I have a newer refrigerator and it quit working 2 weeks ago on propane. I blew out the burner tube with an aerosol computer spray and also around the the sides to get air near the burner and it fired right up. My units air intake is in the floor below so my burner was full of dirt. Turn off the unit before you spray or you will get fire out all the sides. You should be able to hear the burner from the access door when it comes on.

So got fridge running on propane, no problem, must have been operator error!
However water heater on PP no workie. No red light no clicking, no nothing. So will check out someone to clean out as I have no clue but will sure learn. Thanks for all the trouble shooting help y'all!
