Capacitor 270volt 40/4 mfd.
Panasonic air conditioners rely on precision-engineered run capacitors to maintain steady motor performance and reliable cooling cycles. Capacitor failure is among the most common AC breakdowns—your unit either won't start or runs intermittently with reduced cooling power. A fresh OEM capacitor restores instant-start performance and system stability.
Whether your Panasonic unit needs a standard run capacitor, dual-run capacitor, or specialty high-voltage capacitor, we stock genuine OEM parts built to Panasonic's exacting standards. Locate your model number on the outdoor unit's rating plate and match it below to find your exact capacitor. Browse our complete Panasonic air conditioner capacitor parts inventory today.
Repeated clicking typically means the start capacitor is failing—it can't deliver the electrical surge needed to spin the compressor. This is one of the most fixable problems in AC repair. Order the correct OEM start capacitor by model number and the clicking should stop immediately. If it persists after replacement, the contactor may also need service.
The µF (microfarad) rating is printed on your current capacitor or on your unit's wiring diagram. Common Panasonic ratings are 35µF, 45µF, 50µF, and 60µF. Ordering the wrong µF rating can damage your compressor and motors. Always match the exact number from your model's rating plate—never guess or approximate.
Power off your AC at the breaker first. The model number is on a label attached to the back or bottom of the outdoor condensing unit. It's usually a 6-10 character code. Take a clear photo or write it down exactly. This number directs you to the correct capacitor microfarad, voltage, and connector type for safe installation.
If your cooling has weakened and the unit hums or takes time to start, a new capacitor often restores full cooling speed and power. A degraded capacitor causes motors to work inefficiently and consume more electricity. A fresh OEM capacitor brings your system back to original cooling performance and efficiency ratings.

On Panasonic air conditioners, the model number is typically printed on the rating plate on the outdoor unit, often on the cabinet's side, back, or near the service panel. Turn off power before opening any access panel, then copy the model number exactly, including letters, numbers, and hyphens. Enter it in the model number search to pull up the parts matched to your unit. The model number applies to the entire air conditioner, so it narrows the complete parts catalog to parts that fit your specific Panasonic model, not just one type of replacement part. That means fewer wrong orders and a faster repair.
