We just filled up with propane a couple of days ago. This AM neither furnace nor the hot water heater would fire, even though they worked for 3 days after filling. We thought at the time that they filled it too full. Could this be our problem? If so, should we drain some off. Also there are no volts on the yellow wire or the white to LP solenoid at the tank. We don't have a wiring diagram for the propane solenoid. What should the voltage be at the solenoid? What should we try. Absolutely sure the propane is turned on.
Sara, Don't know what coach you have. The solenoid at the tank should show 12 volts to hold it open. Most of the older coaches have had this feature disabled as it is nor required.
Hard to help you out on the WEB. Give me a call at 770-595-3891 and I will see if we can get you going.

Without knowing what year model, it is hard to help you.
But older coaches had a switch on the floor gas detector, that can be kicked with your foot, that had to be reset or switched on to power the tank solenoid. It was part of the old RV build regs. that have been changed. As Gary suggested, you can turn off the gas, and remove the solenoid if you have the parts to take it out of the line. Another simpler solution is to turn off the gas, and take the solenoid apart, removing the inline plunger, and re-assemble.
If your gas detector is more than 10 years old, it maybe need replacing. There is a recent thread about your question, and ? posted they looked for and found a solution for several hundred dollars. Another solution if you want to switch the solenoid is to look at West Marine and use what the marine industry installs. Since the RV industry dropped the requirement, the aftermarket supply need has dried up.
Other possibility could be a bad regulator. Larger propane distributors will likely check your problem for free if you drive by.

Yup, three "controls":
Tank valve. Turn on SLOWLY. Turn off and back on SLOWLY.
Propane solenoid, which is "powered" by the propane detector-- likely at floor level in galley area.
Propane regulator. If in question or over 10 years old, just replace it-- under $25. If the regulator is installed vertically make sure the vent (dime sized screened area) is in the LONG AXIS of the regulator. If installed horizontally, that the vent is perpendicular to the long axis. THE VENT MUST, REPEAT MUST POINT DOWN. The two styles are the same price and same manufacturer. Many parts guys don't know the difference.

Thanks for all your help. We did finally replace the regulator. It seems to have solved the problem. We are in Astoria, Oregon, so finding a marine/RV parts store was no problem. At last, I can have a shower in my own bathroom (alas, and also do the dishes).
Thanks again for all the help.
