Key Kelvinator Furnace Parts and Their Functions
1. Heat Exchanger
The heat exchanger is the core component where combustion occurs. It transfers heat from the burning fuel to the air that circulates through your home.
- Material: Usually made of steel, aluminum, or cast iron to withstand high temperatures.
- Importance: Cracks or corrosion can lead to leaks, carbon monoxide intrusion, or reduced efficiency.
- Signs of issues: Yellow or flickering pilot light, increased carbon monoxide levels, or uneven heating.
2. Burner Assembly
The burner ignites fuel to produce heat.
- Components: Includes burner tubes, ignition system (spark igniter or hot surface igniter), and gas valves.
- Common problems: Ignition failure, soot buildup, or gas leaks.
3. Blower Motor and Fan
Responsible for pushing heated air through ducts.
- Types: PSC (Permanent Split Capacitor) motors, ECM (Electronically Commutated Motors).
- Maintenance tips: Regular cleaning of blades, checking for wear, and ensuring proper lubrication.
4. Thermostat
Acts as the control interface for the furnace, regulating temperature settings.
- Types: Mechanical, digital, or smart thermostats.
- Replacement considerations: Compatibility with furnace model and wiring.
5. Limit Switch
A safety device that shuts down the furnace if temperatures exceed safe levels.
- Function: Prevents overheating and potential damage.
- Troubleshooting: Frequent cycling or failure to turn on may indicate a faulty limit switch.
6. Flame Sensor
Ensures that gas is only released when a flame is detected.
- Importance: Safety mechanism preventing gas leaks.
- Common issues: Dirt accumulation causing false readings.
7. Gas Valve
Controls the flow of gas into the burner assembly.
- Operation: Opens during heating cycle and closes afterward.
- Problems: Gas leaks, stuck valves, or electrical failures.
8. Ignition System
Includes spark igniters or hot surface igniters depending on furnace model.
- Function: Ignites gas to produce a flame.
- Replacement tips: Check for cracks or wear; replace if faulty.
9. Air Filter
Filters incoming air to prevent dust and debris from entering the system.
- Maintenance: Regularly replace or clean for optimal airflow and efficiency.
10. Ductwork and Venting
Channels heated air throughout the building and exhausts combustion gases safely.
- Inspection: Look for leaks, blockages, or corrosion.
