c. Connect the Piping and Traces:
Join the refrigerant strains and piping to the corresponding ports on the brand new compressor. Use a wrench to tighten the connections securely.
6. Run a Leak Check
Earlier than plugging within the fridge, run a leak take a look at on the refrigerant system. Use a leak detector or apply a soapy answer to the connections to determine any leaks. If a leak is detected, tighten the connections or seek the advice of a certified technician.
Eradicating the Outdated Compressor
Step 1: Collect Instruments and Components
Earlier than starting, guarantee you will have the required instruments, equivalent to a multimeter, wrenches, screwdrivers, and wire cutters. Additionally, you will want a substitute compressor suitable together with your particular fridge mannequin.
Step 2: Security Precautions
Unplug the fridge from the facility outlet and discharge any residual electrical energy by shorting the terminals of the capacitor. Put on protecting gloves and eyewear to forestall harm.
Step 3: Isolate the Refrigerant Traces
Find the copper refrigerant strains related to the compressor. Pinch or clamp every line securely to forestall refrigerant leakage.
Step 4: Disconnect Wires and Fittings
Disconnect all electrical wires related to the compressor and the refrigerant tubing. Label every wire to facilitate reconnecting them throughout set up. Take away any bolts or screws holding the compressor in place, gently prying it unfastened if needed.
Step 5: Take away the Compressor
As soon as all connections are launched, rigorously take away the outdated compressor from the fridge and get rid of it correctly.
Troubleshooting Widespread Points
In case you encounter any issues together with your fridge’s compressor, comply with these steps to troubleshoot the problem:
1. Test the Energy Provide
Be sure that the fridge is plugged right into a working outlet and that the facility wire isn’t broken. Reset the circuit breaker or fuse if needed.

4. Clear the Condenser Coils
Soiled condenser coils can limit airflow and trigger the compressor to overheat. Clear the coils repeatedly with a vacuum cleaner or brush.
5. Test the Thermostat
The thermostat regulates the temperature contained in the fridge. If the thermostat is defective, it could not ship the proper sign to the compressor.
6. Examine the Wiring
Test all of the wiring connections between the compressor and different parts. Free or broken wiring can stop the compressor from working.
7. Check the Compressor
Disconnect the facility to the fridge. Take away the wires from the compressor terminals and join a multimeter to them. Set the multimeter to the ohmmeter setting and verify for continuity. If there isn’t any continuity, the compressor is defective.
8. Examine the Refrigerant Traces
Clogged or kinked refrigerant strains can limit the stream of refrigerant and trigger the compressor to overheat. Test the strains for harm and guarantee they don’t seem to be obstructed.
9. Decide if the Compressor Motor is Burned Out
| Causes | Signs | Options |
|---|---|---|
| Overheating | Loud noises, extreme vibration | Test condenser coils, clear them if needed |
| Electrical surge | Burning scent, smoke | Contact a certified technician |
| Inner put on and tear | Gradual lack of cooling, elevated noise | Change the compressor |
| Beginning capacitor failure | Buzzing noise, not beginning | Change the beginning capacitor |
| Run capacitor failure | Compressor begins however doesn’t run repeatedly | Change the run capacitor |
| Refrigerant leak | Poor cooling, hissing sounds | Contact a certified technician to restore the leak and recharge the refrigerant |
