Dual Run Capacitor 45+6 mfd 400v
Friedrich window and portable air conditioners depend on high-quality run capacitors to deliver reliable cooling on demand. When your Friedrich unit hesitates to start, hums loudly, or cycles on and off erratically, a worn capacitor is usually the cause. Replacing it with an OEM Friedrich capacitor is affordable, fast, and restores your unit's full cooling potential.
Friedrich capacitors are precision-matched to your cooling model's exact electrical requirements—voltage, microfarad rating, and connector type must align perfectly. We carry genuine OEM Friedrich run capacitors, dual-run capacitors, and specialty capacitors for every Friedrich air conditioner generation. Identify your model number and find your match in our Friedrich air conditioner capacitor parts catalog below.
Very likely. A humming sound without cooling almost always points to a failed run capacitor. The capacitor gives your compressor the electrical kick it needs to start and run. Without it, power reaches the motor but it can't overcome the resistance to spin. Order the OEM Friedrich capacitor matching your model number and you'll usually restore cooling immediately.
Look at the model/serial plate on the back or side of your Friedrich AC. It lists the capacitor's µF (microfarad) rating—often 30µF, 35µF, or 40µF for window units. You can also check the existing capacitor itself; the rating is printed on its metal body. Always match this exact number when ordering—using the wrong µF rating will damage your compressor.
The model number is on a sticker or plate on the back panel or bottom of your Friedrich window AC or portable unit. It's usually 5-8 characters. Take a photo or write it down exactly as printed. Once you have this number, you can quickly find the correct OEM capacitor, voltage, and connector type for your specific Friedrich model.
Capacitors store dangerous electrical charge even when unplugged. If you're comfortable with basic electrical work, you can discharge and replace a capacitor, but we strongly recommend hiring a technician. A professional installation help ensure safety and ensures you've ordered the correct OEM part. Repair Clinic stocks genuine Friedrich capacitors ready to ship to your technician.

On Friedrich window and portable air conditioners, check the back or side of the cabinet for the model number label. Portable units may also have the label near the bottom, while window units commonly show it on the rear panel or behind the front grille. Copy the number exactly, including letters, numbers, and hyphens, since similar Friedrich models can use different parts. Type it into the model number lookup and the catalog narrows to parts made for your unit. Using the model number filters the full Friedrich air conditioner parts selection, not just one part, so you can match everything to the correct equipment. That means fewer wrong orders and a faster repair.
