re checked valve meter set to 20k ohm and reading .08
Does this mean valve bad?

Yes, it may be what has caused the failures, and I read it wrong its 75 ohms

RV Mechanic: Michael Reush, RV Technician replied 7 years ago
thats what I'm looking for, remove power from the refer at the rear.............let stand a couple of minutes, then try the reset again, you were saying before that it would click, then fail, is it different with the valve disconnected? and the 85 ohm reading shows a good valve...........thats what I'm looking for, remove power from the refer at the rear.............let stand a couple of minutes, then try the reset again, you were saying before that it would click, then fail, is it different with the valve disconnected? and the 85 ohm reading shows a good valve...........

Lets try this one more time, turn the refer off..... disconnect the 12volt supply from the control board. let stand for10 minutes, reconnect the gas valve. reconnect 12volt power, turn refer on electric............if it goes into no cool, do the reset one more time, thanks

Customer reply replied 7 years ago
Ok went into no cool did another reset same results. One added thing helper can hear a click when I switch the refrig on or off
checked 12 volt to board but nothing across fuses also no referring light, probably last response only have 1min left.
RV Mechanic: Michael Reush, RV Technician replied 7 years ago
Thanks, ***** ***** a loss at this point. The only thing I can think of is dirty voltage from the converter getting to the board, but I'm reaching now, you might want to unplug the coach, and use battery only. I'm afraid its time to take it in.... I have enjoyed working with you, please get back to me and let me know what they find. Michael
Ask Your Own RV Question
Customer reply replied 7 years ago
There is a control board on the switches. could the trouble be there.
also I believe there is a heat sensor could that be the problem. One more thing we are on battery only two 6 volt.
