Why Start Capacitors Matter
Start capacitors provide the extra electrical energy needed to get a motor spinning from a standstill. Without a properly functioning start capacitor, motors can fail to start, run sluggishly, or draw excessive current — leading to premature motor failure or tripped breakers. Replacing a worn or failed start capacitor with the correct OEM part restores reliable, efficient motor operation.
Application
- Lennox HVAC systems requiring a 145–175 µF, 330VAC round start capacitor
- Suitable for compressor and blower motor start applications
- Ideal for service technicians performing OEM-spec repairs and replacements
Installation Notes
Always discharge capacitors safely before handling. Verify that the replacement capacitor’s microfarad rating and voltage rating match or exceed the original equipment specifications. Consult the equipment’s service manual for proper installation procedures.
