Product Info
The Lennox CH33 Evaporator Coil is a crucial component in a central air conditioning system, designed to efficiently absorb heat from indoor air and transfer it to the refrigerant circulating within the coil. This process cools the air before it is circulated back into the living space, contributing to overall comfort. The CH33 coil is engineered for high performance, featuring durable construction and compatibility with various Lennox systems, ensuring reliable operation and energy efficiency throughout the cooling season.

Product Troubleshooting
Troubleshooting a Lennox CH33 evaporator coil involves a systematic approach to identify and fix common issues. Here’s a step-by-step guide:
### 1. **Safety First**
– **Turn Off Power**: Ensure the unit is powered off to avoid electrical hazards.
– **Use Personal Protective Equipment**: Gloves and safety glasses are recommended.
### 2. **Visual Inspection**
– **Check for Obstructions**: Ensure there are no debris or blockages around the unit that could impede air flow.
– **Inspect the Coil**: Look for signs of damage, such as dents, corrosion, or leaks in the coil.
### 3. **Check Airflow**
– **Inspect Filters**: Clean or replace air filters if they’re clogged. Restricted airflow can cause the evaporator coil to freeze.
– **Examine Blower Operation**: Ensure the blower motor is functioning properly and that all vents are open and unobstructed.
### 4. **Check Refrigerant Levels**
– **Look for Signs of Leaks**: Inspect the area around the coil for any signs of refrigerant leaks, such as oil spots or frost buildup.
– **Measure Pressure**: Use gauges to check the refrigerant pressure. Low refrigerant levels indicate a leak or other issues.
### 5. **Temperature Checks**
– **Inlet and Outlet Temperatures**: Measure the temperature of the air entering and exiting the evaporator coil. A significant difference typically indicates proper cooling, while minimal difference may suggest a problem.
### 6. **Electrical Components**
– **Inspect Wiring**: Look for frayed or damaged wires that could affect the operation of the unit.
– **Test Capacitors and Relays**: Use a multimeter to ensure that capacitors and relays are functioning properly.
### 7. **Drainage Inspection**
– **Check Drain Pan and Line**: Ensure the drain pan is not overflowing and that the drain line is clear. Clogged drains can cause water to back up, leading to further issues.
### 8. **Control Settings**
– **Thermostat Functionality**: Make sure the thermostat is set correctly and functioning properly to signal the system to operate.
### 9. **Look for Ice Buildup**
– **Inspect for Frost or Ice**: If ice is present on the coil, the unit may be experiencing low airflow or refrigerant issues. Allow the unit to defrost and investigate further.
### 10. **Professional Help**
– If you have performed the steps above and the problem persists, it may be time to consult a professional HVAC technician. Certain repairs, especially those involving refrigerant, require specialized training and tools.
By following these steps, you should be able to pinpoint the issue with the Lennox CH33 evaporator coil and take appropriate action to resolve it.
