Question about Refrigerators

Open Question

I have a taylor 702-27 with serial of k1115126. The compressor was locked rotor. Installed new compressor and weighed in charge. Let unit set for 10 minutes and started. Cleaned condensor with nu brite and let run. Suction pressure is now 18 psi with head pressure at about 225. Compressor has lots of liquid on most of the body about 2/3 down the body of compressor. Can you let me know what you think. Thanks. Ron.

SOURCE: 5 ton goodman ac unit

You MUST WEIGH IN THE NEW CHARGE OF R-22. There should be a label on the side of the a/c unit that states what the factory charge was. This is only a starting point. Once you have the factory charge in the system, then turn on the unit and allow it to stabilize (5 min) . Check pressure on low side and check teperature on low side pipe. Temperature of pipe should be 8 to 15 degrees above what the boiling point of the refrigerant is for the current pressure you are reading. If the temperature is more than 15 degrees, add R-22 in 4oz increments allowing 5min in between each time you add until you are in the "zone". When you do this, your head pressure needs to be 225-250. if you need to cover the coil or block the outdoor fan to do this then do it. Hook up the vacuum pump and start over

did you turn the compressor clutch plate manually for 20 turns?, to displace the oil that is in the compressor's valve as it is new and have some oil in the valves which is very hard to turn at high speed.

you can try to manually turn the compressor plate in the reverse direction, you could un lock it and hopefully not a amjor problem occurs..

good luck,

SOURCE: frigidaire refrigerator compressor buzzes but won't start.

The compressor is seized it needs to be replaced log on to frigidaire.com and find a local service provider if you purchased prior to the end of 06 and if less than 5 years old it has warranty coverage on sealed system repairs. check your manual to be sure. you can try what it is called a hard start might work for a while it uses a larger capacitor to give a bigger kick upon start up.

SOURCE: Freezer works Refrigerator will not cool down

The compressor should be OK this time because you caught it in time. But if the condenser fan stops you need to consider replacing the fan. I have had refrigerators do fine until the fan motor warms up and you are away, it stops. Don't think you should use the refrigerator until the fan is fixed. Sea Breeze

SOURCE: COMPRESSOR NOT RUNNING, HOT

The high side/low side pressure equalization you describe is normal for a compressor sitting idle.

If you have an ohm meter you can check the compressor windings for opens and shorts. If your compressor is 3 phase as you state (this would be very unusual for a residential unit) you should have continuity across all 3 phases and no continuity to ground. Take the compressor out of the circuit before you check.

If the compressor does have crankcase heat, it should have been left on for at least 24 hours before starting the unit. Another cause for failure could be overcharging which could have resulted in refrigerant slugging back to the compressor.

Does the unit have any low or high pressure control safeties? If so, check them too - some have resets. You said the condenser fan ran so it's not likely the breaker blew, but check anyway and also check to make sure you have available power on all 3 phases.

Compressor not working


The useful life of many AC compressors is about ten years. If the fan blows but the compressor will not kick in, the compressor may have seized or locked up. If you need to have refrigerant added, a certified AC tech lisenced to recover old refrigerant and install new will be needed. Most refrigerants of this type cannot even be purchased legally by a non-lisenced repair person. Going by the age of the unit, you should get an cost estimate on repairs and weigh that against the estimated cost of replacing the unit with a newer and more efficient model. Good Luck

How to reset as scales are not weighing properly and new batteries have been inserted


These scales cannot be calibrated so i'm afraid that it's time for a new set. I think they were first manufactured in 2002 and they have a 10 year guarantee which meas you are out of luck. If you are in the UK, this site is a good place to start looking for another set of All Kitchen Scales

DUO-THERM 59516.531 DUMPS THE BREAKER AFTER RUNNING A FEW SECONDS INSTALLED NEW BREAKER, WIRE CONNECTS ALL TIGHT cOMPRESSOR SHOT ? This unit has dumped breaker before but it's instant now


Sounds like you may have a dead short in compressor or locked rotor in compressor.
Either way the compressor will have to be replaced or the whole unit. Check the cost of each before repairing.
Sorry for your problem and good luck.

What is the difrent between LRA and BTU ?


One really has not much to do with the other directly



BTU - British Thermal Unit.- A heat measuring unit. IE:12,000 BTU (British Thermal Unit.) The amount of heat required to melt one ton of ice.


LRA - Lock Rotor Ampere-LRA is nothing but locked rotor current , generally it is located on compressors name plate, when ever pistons locked at a particular position the rotor does not move further at the time rotor draws large current, that current is located on name plate, by seeing that LRA we can know compressor rotor was locked

Compressor shutting down


FC IS FREON CHARGE, WHAT YOU ARE GETTING IS A HIGH PRESURE CUT OFF  FAILURE. THE LABEL PRESURE IS TEST PRESURE. THE RUN PRESURE ON LOW SIDE IN AC MODE IS ABOUT 65 AT 75 T0 80 DEGREES INSIDE AND ABOUT 200-300 HIGH SIDE AT 75 -85 OUTSIDE TEMP. IN HEAT THE LARGE COPPER LINE BECOMES HIGH SIDE HOT WHEN YOU FEEL IT. IF YOUR FREON IS LOW WILL WILL ALSO GET SHUTDOWN. YOU WILL NEED SET OF FREON GAGES AND CONTACT ME BACK

Operating pressures for 134A refrigerant system


I would go for 40 on the suction and 150 discharge, or divide the locked rotor current by 6 and charge so the current is 1/6 of the locked rotor current of the compressor, or by temperature/pressure relation 110* discharge and 35* suction, or get the suction line sweating. The best way is to remove all the refrigerant and then weigh the refrigerant the system is designed for on these critical charge appliances.

WeatherKing Unit needs compressor and is under warranty


have you contacted the company who installed ? try there first, if no luck with the company, contact the manufacture directly, explain to them your problem and try to have them help you with getting the company who installed to do the right thing and replace the compressor under warranty, you may have to pay a warranty install charge, but it would be alot less than having to pay for a whole new compressor, or new unit, put your ducks in a row, get model and serial numbers, date of install, who installed it, and the manufactures warranty on the compressor, that way you will be ahead of the game, best of luck, hope that helped

New compressor


WHEN CHANGING A COMPRESSOR THE FILTER DRIER NEEDS TO BE CHANGED. ALSO, A SOLDERED JOINT COULD BE BLOCKED. YOU MIGHT NEED TO CHECK THEM. DID YOU PUMP THE SYSTEM DOWN FOR AT LEAST 10 MINS AND THEN ADD THE SPECFIED CHARGE??

There are very few parts on this unit. UNPLUG unit jump out the 2 wires to the t-stat. plug it in, if it runs the t-stat is bad.
After that theres the overload /start component on the side of the compressor. UNPLUG remove cover look for burnt wires , wires are ok feel if the compressor is HOT to the touch. if it is it could be off on internal overload. let it sit for a while plug in and listen for a hum or click in the compressor. If there is a Hum then click your back to eather your overload /starter is bad of the Compressor is bad. If you have an amp meter you can check the compressor by clipping the meter on power wire. on the information tag that has the model and serial # there is a amp draw for Lock rotor. If the unit draws Lock Rotor amps the compressor is bad.
