SOURCE: Copleland scroll compressor failure

Make sure ALL moisture and noncondensables are evacuated while the system is down.I would have the line flushed to remove all remnants of burnout.Actually with the age of the unit and amount that needs repaired I would change the unit out to a 410a system and start over.

Superheat should be 8 to 12 degree's. Sub cooling around 18-22. I like to use superheat that way I know the coil is doing all it can do.

This is a bad compressor, or overload-relay kit. Disconnect the power, remove the overload-relay from the compressor, and test the three compressor terminals for continuity . You should have continuity between each terminal, and you should not have continuity between any terminal and ground. If this tests ok, then replace the overload-relay kit. This is a common repair for me, and it is very rare for us to find a bad compressor, so you should be ok. If it is a bad compressor, and it is less than five years old, you have a five year sealed system warrantee, that will cover the repair cost. If it is over five years old, it is not worth repair. When you are done with the repair, make sure you install a 2000 joule or higher, surge protector to protect your refrigerator from this type of repair in the future. Good Luck, Appliance Specialists

My kenmore elite 22.4 co ft. fridge buzzes for a few seconds and clicks. The fan in the back is spinning but the fridge and freezer and not staying cool. Anything I can check for?


HI. I would recommend to check the relay first, then the compressor last to confirm total failure. If both devices test out ok, this will lead to a failed main power control board.

THE RELAY

The compressor relay starts the compressor. A fault relay can result in the compressor failing to cycle on. The relay is accessed from the lower rear of the refrigerator. The compressor relay can be accessed by removing the terminal cover box. The cover is held on by tension or with a retaining clip. On some units. the relay may not be covered at all.(each model may vary). Beneath the terminal cover(if equipped), you will find the compressor relay, and the overload protector as well. The electrical terminals of the compressor motor are located here also. Remove the compressor relay by pulling it straight off from the compressor, gently. Pull the wire off of the side terminal of the relay. It is connected with a slip on connector. Firmly pull the connector, do not pull on the wire. You may need to use a pair of needle-nose pliers. Inspect the connector and terminal for corrosion. If either is corroded they should be cleaned or replaced. There are two types of relays you may encounter, wire coil and solid state. If the relay has an exposed wound wire coil it can be tested for continuity. Otherwise, the relay is of solid state design and requires specialized equipment for testing. Test the relay with a ohm(multimeter), for continuity. Set the meter to the ohms setting X1. With the relay upside down, place the probes into the terminals labeled "S" and "M"(the labeling may vary on each modle). The meter should display a reading of zero ohms, indicating continuity (or if using a continuity tester, it should light up). With the probes still in place, turn the relay over. You should hear the click of the magnetic switch engaging. The meter should now display an ohm reading of infinity (or the tester should not light up). Turn the relay upside down again, place the probe on the "S" terminal and place it on the side terminal labeled "L". The meter should now display a reading of zero ohms (continuity). Turn the relay over and the reading should change to infinity. With the relay upside down place one probe on the "L" terminal and the other probe on terminal labeled "M". The meter should display a reading of zero ohms. Turn the relay over and the reading will stay the same, zero ohms. Now, if the relay fails these described tests, it should be replaced asap.

COMPRESSOR TEST PROCEDURE

The compressor is accessed from the lower rear of the refrigerator. Generally the same proximity of the relay. The compressor motor can be accessed by removing the terminal cover box. The cover is held on by tension or with a retaining clip. The main testing points will be the actual terminal post that hold the relay, gently pull the relay of the terminal box on the side of the compressor, and use the relay holding probes for testing. Once the relay is removed, Place one probe on any terminal and then touch the other probe to each of the other two terminals. The multimeter should display a reading of zero ohms. Be sure to set your meter to 1X before beginning. Now move the first probe to a different terminal and test the other two terminals with the other probe. Finally, move the first probe to the last terminal and test each of the other terminals with the other probe. Every test should have continuity with the multimeter displaying zero ohms. If the compressor motor does not pass all of these tests, the compressor will require professional service. Now test the compressor for ground. With the multimeter still set to X1, touch one probe to bare metal on the compressor housing (it may be necessary to scratch away a little paint to expose the metal). Touch the other probe to each of the three terminals in turn. None of the terminals should have continuity; the multimeter should display a reading of infinity. If any of the grounding tests show continuity, the compressor will require professional service.

Where is the defrost timer on a mcbr1000s


we ll see how u need to check the defrost timer....
Before testing the defrost timer, unplug the freezer to avoid an electrical shock hazard.
A mechanical defrost timer controls the defrost cycle of the appliance. In older models, the timer runs continuously and roughly every six hours, shuts off power to the cooling system and sends power to the defrost heater. In newer models the timer advances only when the compressor or defrost cycle is running - an improvement for efficiency. As the timer advances, power to the heating element shuts off and power is restored to the cooling system. If the timer does not advance, the appliance will be stuck either in defrost or refrigerate mode, resulting in, respectively, no cooling or frost build-up.
The defrost timer is usually found behind the front grill of the freezer. It may also be found behind a cover plate inside the freezer, in the temperature control console, or behind the freezer near the compressor.
To test whether the defrost timer is simply failing to advance, locate the advance screw and turn it clockwise until you hear it click. This advances it to the next mode. If it was cooling before, it is now in defrost mode. Simply wait about 35 minutes and check whether it has left defrost mode and has resumed cooling (listen for the compressor). If it does not advance, the timer motor is probably bad and the entire timer needs to be replaced. If it advances as it should, then you can follow the steps below to test the switch electrically.
The timer is usually held in place with one or more screws. Remove the screws and gently pull the timer out far enough to disconnect the wiring connector. The connector can be removed by firmly pulling and rocking it left and right. It is not necessary to note the position of the wires because the connector plug is keyed so that it can be replaced in only one way.

Test the timer for continuity using a multitester. Set the multitester to the ohms setting X1. The timer has four terminals. Locate the common terminal, it should be labeled "3" or "C". If the terminals are not labeled, determine which terminal coincides with the common wire in the connector plug; it is usually the white wire.
Once you have located the common terminal, touch one probe to it. Touch the other probe to each of the three remaining terminals. The multitester should display a reading of zero or near to zero ohms (which indicates continuity) for one pair of the terminals and possibly two pairs. The third pair of terminals should show no continuity (infinity).
Locate the timer switch and turn it clockwise until you hear it click. Now retest the timer as you did above. One pair of terminals should indicate continuity (possibly two pairs). At least one pair should give a reading of infinity. Note however, one of the pairs that showed continuity in the first test should now read infinity and one pair that read infinity should now show continuity. If the defrost timer does not pass these tests, it is likely that it should be replaced.

Before testing the defrost heater, again make sure u unplug the freezer to avoid an electrical shock hazard. The defrost heater is located at the back of the freezer. It may be necessary to remove obstructions such as the contents of the freezer, freezer shelves, ice maker and the rear or bottom inside panel of the freezer. The rear panel may be held in place by retainer clips or screws. Remove the screws or depress the retainer clips with a small screwdriver. There are three primary types of defrost heater elements; exposed metal rod, metal rod covered with aluminum tape or a wire coil inside a glass tube. All three elements are tested in the same way. The heater is connected by two wires.Label the wires and connections so that you can properly reconnect them later. The wires are connected with slip on connectors. Firmly pull the connectors off of the terminals (do not pull on the wire itself). You may need to use a pair of needle-nose pliers to remove the connectors. Inspect the connectors and the terminals for corrosion. If either is corroded they should be cleaned or replaced. Test the heating element for continuity using a multitester. Set the multitester to the ohms setting X1. Place a probe on each terminal. The multitester should display a reading somewhere between zero and infinity. If the reading is not between those two extremes the heating element should be replaced.

* We have received two reports of cases in which only one pair of terminals shows continuity and when the timer is advanced, the same pair still shows continuity. For these isolated cases, this was reported to be the correct operation of the timer. At this time we have not been able verify this case. This may indicate a specific model or models that use a different wiring configuration than discussed in this article. Also, note that this article applies to mechanical defrost timer controls and not electronic or adaptive defrost controls.

Had theoverload and relay switch replaced still tripping breaker


yes. if you pull all the wires from compressor and use a meter with a continuity bell , touch a copper line and then a compressor terminal. try em all. odds are you'll hear a bell showing continuity or the fact that power can flow directly from the compressor terminal to the chassis= a grounded compressor. or you could have a dead short where the wires in to the compressor aren't touching the case but are touching each other before they go to the motor windings, = a short. either one is an all done situation. time for new .

Testing a compressor to makes sure its not grounded


Just reply to the previous post notify me you need more help

The 3 terminals on the compressor should be like .........
Start { } Run

Common {

a)From Common to Start between 1-10??
b) From Common to Run between 1-10??
c) Start to run should be the added total of what a anb b was
ex. S to C = 5...... R to C = 3 ............S to R = 8

Then check with the ohm meter on its all it ohms scales for absolutely no continuity to ground ...check all the compressor terminals to a copper freon tube (dig the meter probe in the copper some to get good connection)
