Vaporstat meltdown

Fizz

for second time v-stat shorted electrical systerm of gas gun and LWC.  Tech re-installed p-trol.  No significant difference noted, as gauge reading 1-2 oz. Don't know if I should get new stat.

Did the wires short to ground? Were the control wires replaced the first time this happened?

Both good

questions, and I don't know.  Sad to say, ignorance is not bliss.  Had 2 different contractors for each occasion; the first time the tech said if it occurs again it will have to be replaced???  Second occurance different tech didn't know of 1st occcurance, but he said it needs to be replaced.

It would be very wise

to find the root cause of this problem.  A vapourstat -- or pressuretrol -- is very very simply a microswitch with two wires attached to it.  There is no way that the vapourstat itself can "short" the electrical system of anything else.  It can fail closed (always on) or fail open (never on).



There's a wiring problem here.  If by shorting the electrical system of a gas gun or LWCO you mean that they somehow got zapped with 120 when they should have been seeing 24, for example, that's not the microswitch -- that's in the wiring.



The wiring could also short to ground somewhere -- but that really shouldn't damage anything else.  Blow a fuse, maybe...
