Nusance tripping of oil pressure control on commercial refrigeration

Oil pressure trips on semi-hermetic compressors aren't a problem you'll run into every day,however when you do they can be a real pain in the neck to diagnose and repair. Here are a few things to check for when troubleshooting an oil safety trip.<br />The obvious place to start is to check that there's oil in the compressor. Check the level in the sight glass. If the oil level seems low but the compressor stays running, watch to see if the level increases after 10 or 15 minutes of run time:<br /><br />* If the level doesn't increase, add enough oil to maintain about a half a sight glass.<br /><br />* If the level increases, then the oil was logged out in the system and is now returning. A flooding expansion valve can cause this problem.<br />Monitor the superheat at the compressor, and watch for foaming oil in the sight glass.<br /> Freezers without a pressure limiting expansion valve can have this problem when coming out of defrost. Use a crankcase pressure regulating valve.<br /><br />A bad three-phase contactor can cause oil safety trips. The oil safety is wired in series with the compressor contactor, so if the compressor intermittently single-phases due to a voltage drop across a burnt contact, it won't start. In these cases, it's common for the compressor windings to overheat, and for the internal overloads to open.<br /><br /> The oil safety can still be energized and time out. Without a pressure differential, this will trip the oil safety after 90 to 120 seconds. The contactor will open, and the compressor will cool down. Then you show up, reset it, and it runs. Because you find no oil pressure problems, you leave only to return in a couple days to the same problem.<br /><br />Oil pumps are protected by a filtering screen located in the oil sump of the compressor. If the screen become plugged with debris picked up from the system by the returning oil (anything small in the system, such as solder scale, dirt, copper burrs, etc. will eventually end up in the compressor) it can give you the illusion that the oil pump may be failing. <br /><br />Before you change the oil pump, check and clean the screen.<br /><br />Use a good suction line drier as well as a liquid line drier<br />

If the location of the condenser is above evaporator install oil trap to insure the oil return to the compressor. This is applicable to suction pipe only, and piping size should be in the standard size as per unit design.

Kenmore Colds(10671203101) - need to move it on side

shouldn't be moved on it's side but if you have to move it this way stand it back up in new spot but don't run it for at least 24 hours so oils can resettle,but i wouldn't move it on it's side

I have a 3.1 cu ft regrigerator and need to transport it 800 milesaway. It willnot fit upright in ht e car.Can it be transported horizontally.

Yes it can. Rule is for every hous it is laying down it MUST stand up for that amount of time BEFORE plugging in. If you dont let it stand upright before plugging in it will destroy the compressor because the oil in the compressor runs through the lines when laying down. You MUST give the oil time to return to compressor or when you plug it in the compressor will not have oil in it and warp the internal components.

Any questions please comment back to me.

Will I damage the refrigerator by laying on side to transport.

Hi csmgen,

It is advisable to avoid laying a refrigerator on its side. The oil in the compressor can flow into the cooling lines when the refrigerator is tipped onto its side. When returned to an upright position, there is a risk that the oil will not completely drain from the cooling lines and the refrigerator will not cool.

Hope it helps.

Thank you for using FixYa.

Ridgid Compressor ol50135 twin tanks

You need to check if the compressor has frozen up.

LIKELY the check valve has failed or has contaamination under the seat. Often these valves are right where the compressor line goes into the tank.The unit will not hold pressure since the compression relief will vent at shutdown.

Check oil level in crankcase.

Can we lay a freezer on its side temporarily?

You can do it but be sure to let it stand upright for 24 hours before plugging it in and using it. The oil in the compressor will run out into the lines and block it. It needs time to drain back to the compressor.

Is the split ac will function if the distanc is more than 70feet

generally speaking yes, the linesets may have to be sized larger, and depending on location and oil trap may need to be installed to insure oil return to the compressor. There should be line sizing charts in the installation instructions.
