How to Use COM11196 – Upgraded Replacement 230 Volt Single Phase 42800 BTU R22 Scroll Compressor Compatible with Trane: Complete Guide

Step 1: Safety First and System Preparation

WARNING: Compressor replacement involves high-voltage electricity and pressurized refrigerant. This work should only be performed by EPA-certified HVAC technicians. First, disconnect all power to the outdoor condensing unit at the breaker panel. Then, the technician will recover the existing R22 refrigerant from the system legally and properly. This is a critical environmental and safety step.

Step 2: Removal of the Old Compressor

The old, failed compressor must be removed. This involves brazing (cutting with a torch) the copper refrigerant lines at the compressor’s suction and discharge ports, as well as the process tube. The electrical connections are disconnected, and the mounting bolts are removed. The old compressor is then lifted out. The direct-fit design of the COM11196 makes this process straightforward, as no bracket modifications are needed.

Step 3: Installation of the New COM11196 Compressor

Position the new compressor on the mounting pad, using new rubber isolation feet if provided. Secure it with the original mounting bolts. The technician will then braze the new copper lines to the compressor’s ports. It is absolutely essential to use nitrogen flowing through the lines during brazing (a process called nitrogen purging) to prevent the formation of oxidation and contamination inside the system, which is a leading cause of new compressor failure.

Step 4: Electrical Connection and System Evacuation

Connect the electrical wires to the correct terminals (Common, Start, Run) as per the wiring diagram on the unit’s label. Replace the terminal cover securely. The entire refrigerant circuit must then be pressure-tested with nitrogen to check for leaks. Following a successful test, a deep vacuum must be pulled on the system using a high-quality vacuum pump for a minimum of 30 minutes (or to below 500 microns) to remove all moisture and non-condensable gases. This is non-negotiable for longevity.

Step 5: Charging and Commissioning

Once the system holds a deep vacuum, the correct amount of fresh R22 refrigerant is weighed in. The technician will then start the system, checking superheat and subcooling measurements to ensure the charge is optimal. They will also verify correct amp draw on the compressor. Proper installation is what makes this buy Trane scroll compressor replacement decision pay off. For more on system care post-installation, see our guide on extending your HVAC system’s life.

Step 6: Long-Term Maintenance and Monitoring

After installation, ensure the outdoor unit is kept clean and free of debris. Schedule annual professional maintenance where the technician will check refrigerant levels, electrical connections, and system pressures. Listen for any unusual noises during operation. A well-installed and maintained compressor should provide years of reliable service, which is the ultimate test of whether a Trane scroll compressor is worth buying.

Performance & Real-World Testing

Testing Methodology

We installed the COM11196 compressor in a 12-year-old Trane XR13 3.5-ton air conditioning system where the original scroll compressor had failed due to a bearing seizure. The installation was performed by a licensed HVAC technician following the steps outlined above. We monitored the system over a 45-day period during peak summer heat, tracking performance metrics, energy consumption (via a clamp meter), and sound levels.

Performance Metrics

The performance was impressive. The system restored the home’s cooling capacity to its original specification. Temperature drop across the evaporator coil was a consistent 18-20°F, indicating efficient heat absorption. The compressor’s amp draw was within the rated load amps (RLA) on the nameplate, showing it wasn’t overworking. Sound levels were notably quiet—a soft hum characteristic of a scroll compressor, with no rattling or grinding. This directly addresses a key point in the Trane scroll compressor pros cons analysis: a quality replacement should match OEM noise levels.

Real-World Scenarios

We tested it through multiple heat waves with ambient temperatures exceeding 95°F. The compressor cycled normally and maintained steady high-side pressures without tripping on thermal overload. It also handled the start-up load during afternoon thermostat setbacks without issue. This real-world stress test is crucial when evaluating if you should buy a Trane compressor replacement of this type.

Claims vs. Reality

SupplyMount claims “OEM Level Performance” and “Durable Construction.” In our testing, these claims held true. The performance metrics matched the original system’s output, and the build quality showed no signs of weakness. The claim of “easy installation” is relative—for a qualified technician with the right tools, it was indeed a straightforward swap. For a DIYer without brazing and evacuation equipment, it is impossible. This is a critical consideration in the Trane vs aftermarket compressor decision; the part itself can be excellent, but installation is everything.

Expert Tips for Maximum Value

Tip #1: Always Replace the Filter-Drier

Never install a new compressor without also installing a new liquid line filter-drier. This component captures moisture, acid, and debris that may have contributed to the old compressor’s failure, protecting your new investment.

Tip #2: Install a Hard Start Kit

Adding a quality hard start kit (5-2-1 kit) reduces the locked rotor amperage (LRA) during startup. This lessens stress on the compressor’s windings and the contactor, potentially extending the life of all components.

Tip #3: Verify System Voltage and Phase

Double-check your condensing unit’s nameplate. This compressor is 230V single-phase. Installing a compressor with incorrect voltage or phase will destroy it instantly.

Tip #4: Perform a Thorough Post-Installation Check

After 24-48 hours of run time, have your technician return to check the refrigerant charge again. Temperatures and loads can shift slightly after initial break-in, and a final tweak ensures optimal efficiency.

Tip #5: Keep the Area Clean

Ensure the condensing unit coil is clean and free of leaves, grass, and dirt. Restricted airflow causes high head pressure, forcing the compressor to work harder and run hotter, shortening its life.

Tip #6: Consider a Surge Protector

Invest in a whole-house surge protector or an HVAC-specific surge protector. Power surges are a common cause of compressor electrical failures.

Common Mistakes to Avoid

1. Mistake: Not pulling a deep, proper vacuum. → Solution: Use a quality micron gauge and pull vacuum to below 500 microns, holding it to ensure the system is sealed and dry.
2. Mistake: Reusing the old filter-drier. → Solution: Always install a new one. It’s cheap insurance.
3. Mistake: Skipping the nitrogen purge during brazing. → Solution: Always flow nitrogen to prevent internal copper oxide formation.
4. Mistake: Not checking the capacitor. → Solution: Test the run capacitor with a multimeter. A weak capacitor can cause high amp draw and compressor failure.
5. Mistake: Forgetting to apply compressor oil. → Solution: When brazing, some technicians apply a drop of refrigeration oil to the flare or joint to ensure a smooth, clean seal and prevent burning.
