Commercial freezer 404 system what is the correct vaporat ing temp or psig


If you are asking about the pressures that are on the compressor, you need to be aware of the temp of the room that it is in and you need a manifold guage set.

I've had the refregerator for 10 months.. All of a sudden water is appearing on the floor next to the refrigerator. Where could it be leaking from?


Pull it forward and seei if the drain pan is either overflowing or empty. If it,s empty, check the drain isn't blocked, causing meltwater to leak from inside. If it's overflowing, check the door seals properly and the defrost settings are ok.

Samsung side by side refregerator door left open for some time, the door warning chime does not come on


Check the switch just inside the door. If it's not chiming, it may not be switching the fan either.

Model km-250baf hoshizaki with weighed in correct amount of 404a the head preasure risies to over 400 psi i think it is the txv advise me if i am right


There are a lot of variables that cause high head pressure. Be sure the cool ing fan is operating properly. It should come on whenever the condenser coil feels warm to the touch. It will cycle on and off as the pressures change. A clogged up coil will also cause high head pressure. If you don't have sufficient water flowing over the evaporator plate, where the ice freezes, the head pressure will go up. You need to check the low side head pressure as well. Weighing the charge is a good start to charging the machine , but the first question I would ask is why are you charging it? Was there a leak, or compressor change?
If you had a compressor burnout, did you replace tthe drier-filter?If not, it may be stopped up from burnout residue. That will also cause high head pressure. If you did not vacuum the system there may have been refrigerant still in the system before you started the new charge. Check the items I mentioned and see if that helps.

The compressor on my refregerator seem to be overheated it is a side by side the insides of the doors are warm and the freezer will not free but it is running there is cool air in freezer


The doors should be warm. There or heaters in the doors or what they call a yodelers loop in the frame around the doors that keeps condensation from forming. Make sure the fan if blowing on the compressor and the fan inside the freezer is also running. If so be sure there is no ice built up on the bottom inside back panel of the freezer. If so you will have a defrost problem and the coil is full of ice and not allowing the air to flow through it and cool the fridge. If there is ice, the heater behind the panel is most likely bad.

The freezer section of our ge refregerator keeps making a loud buzzing noise and causing our food to frost. I have already lowered the temp.; however, it doesn't seem to help.


This would indicate moisture is getting into the freezer and not getting out.
Run a manual test of the defrost cycle.

Master built 2 door freezer model BLG-48HD serial 016254 still in warry. How do you tell how long defrost and time it goes into defrost? Also box won't pull down to temp, high alarm goes off. temp 25 in...


most units are on a timed defrost that occurs at different times so finding the exact time will be hard but defrost times are about 30 minutes. from the pressures you posted I'm thinking that the condenser fan is not running or the condenser itself is plugged up with dust. (i'm not very familiar with r404 but for most other refrigerants the hi side pressure is really hi). if its still in warranty you would be better off to call your service company after your sure the condenser itself is clean to prevent a charge for impproper maintanence. thanks peyton
