Take a look at this schematic. Would you say crankcase heater is wired correctly being powered all the time?
Of course it would be even better if it was wired through auxiliary side...
I agree. Ice and have identified this to them. They still don't seem to get it. The money they are maybe saving on electricity they are spending 10 fold on compressors lol

Also, this week I had assumed that the sporlan sorit EPR's were controlling temperature of coolers, I realized that they have the RMCC set to control circuit temps with pump down, because of this I...
Have been doing some work recently on some Hussmann racks at a food plant we service. I'm new to the plant and have slowly started to find a lot of problems with there system. They have installed...
Anyone know where I could find a wiring schematic for this rooftop unit? Have checked lennox website and can't find anything.

I have a number of cases sweating in a supermarket I service. They are sweating enough that water is pooling outside kick plates. It is the drains in some cases sweating but I've also got frozen...
Wow, I feel really stupid now. Well lesson learned.
Thanks guys.

No has a fixed metering g device. Lol think I just answered my question. Lets say I started compressor up and then shut it off. And tried to start it up again, it would not start until my pressures...
I replaced run cap, did not change contactor as it looked good to me.

Although more i sit and think about it. Could have been going off on internal overload right?
Would a low charge cause it to be tripping on overload?

Diagnosed a compressor as needing to be replaced. Figured was on its way out. Carrier condensing unit , compressor seemed to only intermittently start up last week. 208v single phase, contactor good,...
Indirect fired. Actually did not check my gas pressure, guess that would be good idea, lol that's how new I am on hvac systems. It does have a maxi valve on it. This is modulating gas valve right? I...
Working on an engineered air model: dj-40 . Has a djm 3.4 controller. For the passed year the unit keeps locking out on flame failure, have had numerous guys changing the flame sensor on it....
If system is pumping down on defrost then don't think it is hot gas defrost. Case must have had heaters added to change to electric defrost.

:confused:
im not sure, how would i tell what type of valve i have?
I was also going to ask that, if i have systems flooding back to rack i am loosing capacity ? I also have tried to check valve...
lol no it is a low temp r22 rack. freezer has had that head on tx valve for a long time i think. freezer has been running a little warm. other guy that looked at it thinks its the head on the tx. i...
Was working on a freezer the other day and repaired a leak on a tx valve, r 22 rack. noticed that someone was playing with valve and it was flooding back to rack so i adjusted to 10F superheat at...
I work in alot of older supermarkets and run into times when you cant read the nameplate on the compressors anymore. Is there another way you can identify the model of compressor that is being used?...
lol ok guess i have no idea what im doing. my liquid pressure was 140psi. so my next question what should these pressure regulators be set to? thanks for the help
thought maybe my problem could be low head pressure. so i adjusted dropleg regulator to 200psig. system is 404a.
I have got a solenoid valve that is controlling temperature in 2, 8' open display cases. valve cuts liquid flow when temperature is reached. valve seems to not always be closing when thermostat...
Took this picture of an epr on a rack today. why is the bottom line off the epr frozen up like that?
problem with the valve? the pilot line is leaking through the valve and leaking through the...
heres alarm box. this rack had 6 comps, so 6 buttons for each comp right? then what would bottom 2 alarms be? al and at?
haha ya thats the other problem too. some of these racks are hacked up real bad, dont even know where to start
I recently started doing service at stores with really old hussmann racks! I am trying to understand the wiring inside the racks but I cant seem to find schematics anywhere for them! I think they...
thanks guys
Would anyone have a link to a site that would show what all my temperatures should be maintained at for all cases/coolers/freezers in a supermarket? I have a rough idea what everything should be...
haha thanks. dont scare me away before i get started!
ok so lets say it is a dt bunker with a sol. and epr in it? i guess im just asking theres no way the gas can go backwards through epr in case?...
I guess I am supposed to give an introduction as this is my first post. I have done installations in supermarkets since i have started in the trade so havent had the opportunity to learn as much as I...
Do dual temp bunkers that are switched into medium temp get a hot gas defrost? wouldn't the epr inside case stop hot gas from getting to the coil? Just curious no one has ever explained this to me. I...
