Give him many beer so he heads north instead of west- I would love to have SLcTech up here to straighten up a few more Lennox Proctologys.
Parden me while I wipe the spit off my phone
that's MY proprietary embedded reaction to
proprietary embedded systems!
Hold the windows- and I have seen the same setup...
We call it a walk-in cooler!
I'm thinking that some smart fella will integrate an on-air "pilot" D/A signal that your phone will use to automatically set the A/D converter gain.
Could it work?
Nobody see the irony of trying to get a Carrier to work in Lennox, SD?
Gotta be breaking some ordinance here!
As long as you're not also the guy that installed it!
I've never worked on this model, but from your post I have one question & one suggestion.
Since you've had the only reaction by swapping the comp contactor, what is its' coil drawing?
You'd be entering the region of R134's critical temperature, where, no matter how much pressure you apply, it will not condense.
It's near the 100 deg c I believe.
Those twins were 20 year olds, right?
Things were great until PHM found that he
wasn't wired for 220.
Actually not bad out to 300yds.
The 150gr at 2670 mv sighted in at 200yd is 3" hi mid-range and < 8" low @ 300yds.
They were regarded the most accurate of the levers, had a visible cocked...
Darrin, I don't know the case at all, but it's probably some simple thing.
Firstly, clear up some terminology for me;
"eggcrate" could that be what we call honeycomb filter?
Can it be removed...
I don't consider that to be the problem at all.
Lots of non-critical coolers are paired on a condensing unit.
Fix the problems causing the repeated failures, don't guess.
Samir, when test running the spare compressor, did you have the correctly sized run capacitor on it?
A scroll is an excellent swap in this case, every start being unloaded.
Sat on them for so long that I'm naming my retirement digs for the pattern etched on my butt...
The diamond ass ranch, hee haw
Enjoy your retirement, Wes.
Because unit runs when start capacitor is switched manually does not validate windings.
If a start-run short exists, developed emf across R winding may not reach the 170v needed to pull in relay....
OC7, is that 2nd evaporator going in the same freezer?
If so, I would suggest a second clock to stagger the defrosts.
You get full advantage of the condenser as one coil is cooling at all...
Don't get hung-up on what the other guy says.
Do your own game... full set of readings, amps, both coils condition, load/use variation etc etc.
Scrolls do "wear in", usually develop noise with...
Analog, IcanHas, analog!
Without that finicky wide-screen readout, my
cold weather vom works fine on alky batteries.
In -40 I have a select digit for digitals.
Ok, hello Brian.
Referring to the Grasslin timers in commercial refrigeration;
I've noticed that the enclosed relay powering defrost seems somewhat more prone to weld or burnout (can't file ...
Glad to have you as an addition to this site.
Brian L , I look forward to your expertise in this interesting part of the HVAC field.
See PHM if you had done like me:
After skipping 80 days in gr 12, I vowed that I would never again sit in a classroom.
1. Typical counter-cooler evaps do not have a distributer, with its' inherant pressure drop.
B. Same evaps don't even come equipped with equalizer stub.
3. PHM... you're crossed up with...
Sorry, PHM but I have to disagree with you.
The reason being I just returned from a Pizza chain that has 8 coolers on the line, all internally eq. txv's, all pressure controlled.
...In my experience in commercial refrigeration, if an expansion valve equalized on shutdown, I would replace it. ;)[/QUOTE]
I would like to add;
If a properly operating txv (internal OR ext...
I just looked at the manual, 121 pages.
Not going to try read that on my dinky phone.
So, if anyone knows if this fridge has a defrost clock, please chime in.
This should really cut down your drinking, no?
With 90% RH and a 40f to 20f cycle,
it should drip with every cycle, I'm thinking.
Something for you to do.
Check that condensate drains properly.
Why not use a standard cataloged lo-profile
Give yourself a hand for saving 66%
And give Hobart the finger for their greed.
Is your coil #2 out returning to the wrong leg of 277v ?
And you're sure there's NO v drop across actuation switch?
Post Partum Elation?
What's measured voltage ACROSS coil?
Stop measuring to grnd, measure v across switches etc to find the under-load poor connection.
Tim, looking at your ohmed windings, I suspect that you have a start winding-run winding short. It reads correct ohms on each winding, but cuts across the short on R-S measurement, reading no more...
Your original potential relay lists a pull in v
of 170 to 180.
Have a helper on the breaker while you catch the S winding voltage.
Your problem may be the off resistance values of R-C S-C.
Regardless what the big kids said,
I wish someone had told me
Don't pee on the electric fence!
You city folks, this may go over your head...
kinda like I did with the big kids watching.
As always, my weapon of choice would be a
plain VOM, or a clamp-on with vom included
Well, there's one correct call (or 14) for newbie BlueLine.
Give him a thumbs up
delete...tech found trble.
Hey, OLB -as a guy with 14" thick walls,
I feel for you!
IIUC, your wall has vapor barrier-insulation-siding.
70f inside, -40f outside, air leakage into wall.
At some temp-related varying dew...
I've passed it... no smarter.
"As you grow older, you grow wiser"
came from a 12 year old.
When recommended by the compressor mfg.
Otherwise I'd hold you liable for costs incurred as a result of introduced crap into the system.
(sorry for the technical jargon).
Snupytcb, meine lippen sind versiegelt!
I find tapatalk a limiting piece of crap.
For Android users, in menu, check "Desktop view"
Then you're no longer bugged with the tapa option, and you can scroll around the entire page.
The way I heard it, only drivel can be spoken on the open forum eg: hook red hose to lo side, blue to hi. Fill till compressor squeals.
Apparently it's a clever ploy to foil Google from indexing...
Zener or "clipping" diodes are used for voltage regulation.
edit: Can't quite make out the schematic designation, but it looks like the letter N rather than an arrow & bent line...
Had this happen on a 50 ton unit...
Destroyed 2 rods.
They don't take kindly to pumping oil!
That case is not meant to reach -20f,
check the specs.
I've never seen a True product deliver anything above minimum performance!
