FRIDGE ON PROPANE

Originally posted by Kup-Pod In my old tent trailer I used to get tiny spider webs in the burner orifices that were quite sticky.  Compressed air may have blew through them but not cleaned the, out completely.  Maybe the gas is getting through but not at a sustainable volume.  It would be worthwhile to clean the burners orifices with a wire.

No wire please! Use denatured or isopropyl alcohol. Poking  a wire through there could damage the orifice.

podwertz:   yup, they work strong!!!!  and gas water heater.  out to tear it up again as we speak!!  hogone

Not knowing just where and how you used the compressed air, make sure the chimney is clean. Run a rag up and down it, etc. I was surprised how little of a amount it takes to disturb the flow and keep the thing from running right.

If its clean and makes a good blue flame initially but then goes out it after a few seconds it could be the flame detection signal, which is there to sense whether the flame is lit or not and shut off the gas if not. I think the signal is produced by a thermocouple. You can disconnect the thermocouple and check it with a multimeter on the millivolts setting. I think is should be producing about 25 millivolts but I could be mis-remembering.
