How to Test and Diagnose a Faulty Lennox HP20-261-1P Capacitor
Visual Inspection
Start by turning off the power supply and inspecting the capacitor for obvious signs of damage:
- Swelling or bulging tops
- Leaking oil or corrosion
- Burn marks or cracks
Electrical Testing
Use a multimeter set to capacitance mode to measure the capacitor's value. Compare the reading to the specifications printed on the capacitor:
- If the reading is significantly lower, the capacitor is failing.
- If the capacitor shows no reading or is open, it needs replacement.
Professional Assessment
When in doubt, consult an HVAC technician who can perform more precise tests and ensure safe handling.
