Your problem with WIC freezing used to intermittantly occur from
solenoid coil residual magnetism.

You said that a solenoid was changed in jan, what about the other one?

The problem is likely...

Running for 2 weeks, eh?

If the vapor barrier were on the wrong side, the insulation would probably now be getting damp.

I would inquire.

Sounds like the old cooler also had problems.

Bbeerme, the concern is the immediate capacitor failure due to welding of the points,
not the attempt of extending point life, which Tecum doesn't even mention.



cheers

you may be getting excessively hi voltage at early am milk time.

Unless I misread the above 71Chops quote, it is incorrect.

Won't be surprised if they're assembly line cold solder joints,

Your president Trump's wall... sounding better & better.

Remember, on a 20 deg f day your car ac compressor will not cut in because of the lps, or an ambient sensor.

And the fact that you're losing heat thru the evap before the heater coil?
Up here...

David, what is the defrost schedule?

What's happening is that you are believing that sentence to actually carry accurate technical information-which it does not.

Well CRussell, we've solved enough for tonite.
I'm heading for...

Really?
You would change the TXV element based on the given info?

So, what's the purpose of the TXV?
That's right... to control SH.

So, what's the SH of this system?
We have no idea...

Huh, never heard of them, must be a 'Merican thing?

So if a mere 1/4 turn of the TXV brings you 3 deg c closer to your setpoint, why not just do a proper SH adj on the txv?

At least before changing txv, element or screen.

Ok, "Batoche Bob" eventually see you over there.

Get caught like that a few times and my analog Simpson doesn't look quite so silly.

An analog meter can perform some tasks that a digital cannot do.

Welcome aboard, Bill mcC.

It's also helpful to amp out a control ckt thats burning xmers, coils & fuses.
Any coil that isn't pulled fully in & shunted is in overload condition.

good luck

It's all ok, as answers and final analysis may be somewhat off.

Farm tech, all the dairy & pmu tanks I've seen have receiver equipped cond. units.

Why bother with sc readings, or is it specifically asked for in the equipment manual?

This IS a milk tank...

I believe the LAL 310 has about 33kbtu @ 25f . Coupled with the 7k coil and allowing 12kbtu for the 1 ton txv fed coil, it appears balance point is about 25000btu @ 22f with 13f td. That's ...

Also, I believe that the thinner, longer wires in the start winding have more inductive reactance.

A bit of troubleshooting right there... it being temperature-dependant & not a total false alarm.

I think he means "max capacitor operating voltage"

in which case he's correct...v drop divides evenly across the two diaelectrics.

Actually, no, PHM.

My problem is that I seem to have an opinion on everything, which is ok if I could keep my mouth shut.

My attitude came at age fifteen- that's when the physics teach slid my desk into the hall for the year.

With all due respect-you're wrong.

What you have is cause AND effect at the same location.

Re-read my post... L2 handled the SAME current that destroyed L1, just fine.

If you chose to...

The rest is of no consequence...the heat & destruction is caused by resistance at the point of damage.

Remember, on a working system L2 is carrying the identical current as L1.
