High voltage capacitor 1.05 mfd.

Capacitor, hv

Dual Capacitor 370 volt 20 + 4
A capacitor stores an electrical charge, then releases it to start and run compressors and motors. If the motor or compressor is slow to start or doesn't start at all, it's likely the capacitor is defective. You can often tell that a capacitor has failed because the part will bulge or leak. You can also use an analog-style multimeter to determine if the capacitor has the ability to store an electrical change then release it, and a capacitor tester to measure the part's capacitance rating to assess the viability of the part. Repair Clinic carries replacement capacitors that power central air condensing units, furnaces, microwave ovens, and other appliances, including capacitors manufactured by Emerson, one of the leading names in heating and cooling products. It's important that you choose the capacitor that matches your product, so type the full model number of the appliance or equipment into our website's search bar, then choose "Capacitor" from the part category filter to identify the specific part you need. You can depend on Repair Clinic to provide you with all the help you need to test and replace parts like capacitors. We have thousands of instructional videos, articles, and model-specific schematics to guide you through troubleshooting your equipment's malfunction and take you, step by step, through the repair process. When you partner with Repair Clinic, the fix you're looking for is only a few clicks away.
Emerson appliances and equipment have specific repair considerations. Below are the most important questions customers ask about Emerson parts.
Wear from age and heat is the #1 cause. Electrical surges, contamination, and mechanical stress also shorten capacitor life. Regular maintenance and using genuine OEM Emerson parts extend service intervals significantly.
Look for a data plate or label on your Emerson unit — location varies by product type but is typically on the door frame, back panel, or inside the access panel. Enter the full model number in our search to match the exact OEM capacitor for your unit.
Some aftermarket parts work, but genuine OEM Emerson parts support proper fit and performance and guarantee exact fit. Aftermarket alternatives can vary in voltage, dimensions, and durability — OEM is the safer choice for critical parts.


Ordering Emerson parts online is simple and helps you find genuine OEM parts. With same-day shipping on most in-stock items, you'll have your replacement part fast, minimizing downtime. Our model/part number lookup finds the exact OEM part for your unit, and every order is backed by our 365-day return policy and price-match guarantee. If your Emerson capacitor is failing — showing symptoms like reduced performance, unusual noise, or complete non-operation — replacement is typically the fastest fix. Browse our full library of Emerson repair resources for troubleshooting guides and installation videos.
Before ordering an Emerson capacitor, record the model number from the equipment that uses it. On Emerson microwave ovens, check the inside door frame, back, or side cabinet. For Emerson air conditioners and other heating or cooling equipment, look on the exterior nameplate, side of the cabinet, or behind the access panel. The model number identifies the entire unit, not just the capacitor. Type it into our model number lookup and the catalog narrows to parts made for your unit, across every associated part category. Matching the full model helps account for differences in voltage, size, and design, so you can choose compatible Emerson parts without sorting through unrelated results.

Solid diagnostic work is what makes an Emerson repair go quickly, and Repair Clinic's online library was built for exactly that. Symptom articles, part testing videos, wiring diagrams, and step-by-step written guides give owners and technicians the reference material to isolate the failed part. Look up your model number to match the right OEM part, then follow the installation video.
