Common Symptoms of a Failing Capacitor

A weak or failed capacitor is one of the most common causes of air conditioner breakdowns. Signs that your Lennox 46W14 capacitor may need replacement include:

• Outdoor unit will not start.
• Condenser fan hums but does not spin.
• Compressor struggles to start or repeatedly trips on overload.
• Air conditioner blows warm air.
• Outdoor unit starts intermittently.
• Breaker trips during startup.
• Higher electrical consumption due to inefficient motor operation.
• Bulging, leaking, or swollen capacitor casing.

If you live in Calgary, Edmonton, Red Deer, Lethbridge, Medicine Hat, Fort McMurray, Grande Prairie, Airdrie, Spruce Grove, St. Albert, Sherwood Park, or Leduc, summer temperatures can place heavy demand on outdoor air conditioning equipment, making failed capacitors a common service item.

Across the Greater Toronto Area, including Toronto, Mississauga, Brampton, Vaughan, Markham, Richmond Hill, Oakville, Burlington, Milton, Pickering, Ajax, Whitby, Oshawa, Aurora, Newmarket, and Hamilton, capacitor failures are frequently seen during periods of high heat when compressors experience repeated starting cycles.
