2004 Monaco diplomat I have no propane going to coach tank is 50% full. I replaced outside switch that activates valve and still no luck. Could the solenoid be bad and can you turn valve off and take solenoid off without propane coming out.

Yes the solenoid can be bad. When you turn on the switch do you hear it click?

Check all wiring connectors for corrosion.
On my coach the shut off valve is before the solenoid, so in theory I could remove the solenoid valve. Don't know about your coach.

I don't see a manual shutoff valve between tank and solenoid valve

Solenoid can be separated from the solenoid valve stem

Did you have power to the switch , before you replaced it ??

Most of these solenoid controlled set ups , the power to the solenoid comes from the fuse ( on a coach battery circuit ), through the propane leak detector ( that shuts off flow in the event of an alarm ) to the switch ( used when tank is being filled ) then to the solenoid .

Just for information and clarification, my previous 1997 coach had the LP detector solenoid shut off circuit. However, my 2006 Discovery does not have that circuit. The tank solenoid is only controlled by the remote fill shut off switch.
