Been there seen that, it's the LPC. That is what is ultimately controlling the contactor, because it is not making proper the contactor will react with the chatter.

Bean Counters don't call at 1AM....maybe 1 PM ...night stock bosses call at 1 am.
Maybe some one needs to make an App
www.lantric.ca great source for all brands of replacement contact kits...used to buy all the time...always worked out fine.
Always found the Yellow Jacket worked great, but 4 lbs./month on a rack is near zip. Could be a pinhole in overhead suction line that you will never find.
Or if you suspect the service deli cases ...
Looks like a late 80's to early 90's Hussmann rack,,,agree no problem...for the valve that is.....rack has likely made someone rich with service calls by now though:grin2:
May I suggest a SAVOD (Seasonally Adjusted Variable Open Door) control system hand crafted and tailored to your specific latitude,longitude and altitude.
Extensive studies and exhaustive research...
Do some searching and check out the manufacturer's websites the info is there. example http://www.hillphoenix.com/display-cases/miscellaneous-tech-data/ you need to learn all the info related to the...
Pull the pans and look at the piping configuration.
I am guessing that the solenoid is on the suction line, when energized the case is in low temp. mode and will run at rack EPR setpoint, when...
Because the carrot would have to be placed on a stick in the discharge air and the horsepower will continually try to catch the carrot but never quite get there and run on and on and on.....
Did you remove the compressor terminal plate from the compressor and clean all internal parts of the terminal plate?
Had to do this after a line to line short from a left behind knockout on startup....

Low voltage and condenser fan motor on way out (noisy) contributing to start problems?
Oh now I see the high superheat on your guages...don't own a fancy set like that,,,,,but would have caught the problem before case was even started, when I noticed the wicked pitch on the fan...
Factory styrofoam peice at top behind discharge honeycomb was too big, (cut on wrong angle)blocking majority of airflow.
Found this on several Hill end bunks at same store.
Liquid line drier in case was partially plugged, S.G. was cut in before drier??
What are the components in each case?
Suction line solenoid with 90 degree EPR for MT operation?
P.S. I find the larger rotating vane anometers do not work in the supermarket...
As an everday supermarket service tool, the Testo 410-1 has worked excellent for me.
Used to swear by the Alnor Jr. ( it is more accurate when 100% calibrated) but fragile and fickle when trying to...
Are the systems on 5/8" liquid lines still using the original 5/8" solenoid valves that remain energized through defrost?
It's possible these solenoid valves are not allowing proper return flow to...
Must agree on the EPR for dual temp.
We install lots of new dual temp. coffins.
Each section (8',12', end bunk) has its own dual temp. switch that energizes suction solenoid for low temp. and...
Just to clarify
From this discussion it sounds like higher amperage and hotter compressor head temps are expected from a discus compressor with a blown valve.
Should be the opposite from my...
They just like to stop for no definable reason....waste of money, from my all seeing vantage point....reverse motors=useless waste of money ,,,,ecm=useless waste of money lol end of discussion
Interesting idea, but I'd be concerned about stress on the condenser during its most extreme temp. conditions.
As for my previous "guarentee/ assumption" .......true these should not be made...
[/QUOTE]One thing I'd like to say since it's been mentioned. If I were choosing my own components for a rack, I'd choose the ball valve actuating motors over 3 way valves. For the reasons here and...
Common problem with split valves in cold weather locations. When the outside temp drops and the condenser pressure is lower than the suction manifold pressure you will get migration through the...
The original liquid line solenoid valve on a Kool Gas system is a special Sporlan bi-directional type.....you said you added this system to the rack? Could be wrong solenoid valve, or add check check...
Probably not needed in your area but if equipped, be sure to manually override the holdback valve and shut off receiver bypass. On a KG rack you can drop the condenser pressure very low by putting...
Cool, Ice.
There are always many answers to Supermarket Questions, this quiz correctly portrays that ( but then again refrigeration service in general is like that across the board) I would...
Just throwing out some "corrections" to the Supermarket Quiz.
#2-The answer should be a,b and d. seen many a faulty defrost timer (gang clock) causing multiple system ice ups.
#4- The answer...
Bought a few on Ebay too, but you take your chances(some may be 50 years old, my guess is the price goes up now ...thanks Mspanky:D). The Testo 410-1 (does not do humidity but who cares) or...
1-1/2 hours is pretty slow, especially if you communicate the urgent need. I like to keep 200 lbs. gas onsite at all of our stores, maybe a good time to sell the store owner on it.
You can only listen in awe and imagine as the "fridgys" retell their after hours stories at the parts counter.
Never liked the s/s braided hose and leaks on sidewalls , have not had many problems with "super" hoses myself but.........
Years ago (around when the s/s braided first came out) we were buying 10'...
Thanks. I'll try them in the a.m. What time zone or city are they located in?
Just tried it............says sorry no longer in...
Just tried it............says sorry no longer in service!!
Looking for a tech support phone # for Com-trol. The 1-888 # I have does not work from Canada and the old 419 area code # on my manual just rings busy.
Have a 4k that is alarming as "blown box"...
As mentioned there is no exact %, the level will vary depending on ambient temps. and load demand. Typically the receiver level might range from 20 to 50% depending on the extremes of your climate....
This is to keep the clear plastic price tag covers from plugging off the drain. The theory is that water will always flow down while prices will always go up, I hear these cases have not worked well...
Hi Frost. Was the newly installed piston, the latest version from Alco, or same as original? We had a # of redesigned (preproduction) replacement ESR12 pistons sent to Calgary to change out the...
Former DF(2 weeks ago)...............but I'm all right noooooow :D Got 26 OT since Friday though, theres no escape in the Rock and Roll World of Supermarket Fridgy.
For the most part, the...
I have seen alot of similar stuck Alco ESR valves, probably similar scenario, let me guess.....5 deck freezers, sys# somewhere between 8 to 13, only does this on days above 25º C , is fine on cooler...
If that was true Ontario would be inhabited by 66 million people by now. Bought a testo 410-1 today, approx. $125.00 Can. don't really need the humidity reading of the 410-2 for checking display...
Congrats Gruntly.
Funny, I noticed a direct connection between a Canuck members proximity to a losing hockey team and the numerous lenghty essays offered in this contest. :D
Holy Smokes!! Did some research, never knew the last Leaf's cup was won during the last year of the original six!!! I'm convinced that cantankerous Harold Ballard has jinxed the Leafs until 2017,...
Hey Spotts, I did'nt see any 2nd round schedule as of yet. A lot depends on tonights game if Calgary wins, Colorado plays Dallas, if not you play Detroit from what I figure.
Personally, I watch...
Ok, mentioned "Dancing with the Czars" at convention to my wife...piqued her interest. Dice, you been keeping up with those lessons?:D
Thanks Gruntly......though I must admit your previous prose almost scared me away from entering. I have a short trip planned to Phelpston this summer, if I win I will let you use it for 1 week. :D
Why would I like to win a Testo 410-2 vane anemometer?
-My Scottish heritage prevents me from purchasing 1 until the contest is over
-I have used our shop owned 410-2 that came with a recently...
Yeah thats it a "week" breaker, you did say it tripped on weekends. :D
