Replaces / Cross-Reference Part Numbers
- 97F9850
- 97F9970
- Also replaces other brand capacitors with matching 50/5 MFD and 370V or 440V specifications.
Compatibility & Fitment
- For use in a wide range of HVAC systems, central air conditioners, and heat pumps.
- Functions as a direct replacement for units from various manufacturers requiring a 50/5 uF dual run capacitor.
- Always verify the MFD and voltage ratings of your original capacitor before purchasing.
When to Replace
- Compressor or fan motor hums but fails to start.
- Component runs intermittently or not at all.
- The capacitor case is visibly swollen, bulging, or leaking oil.
- Capacitance tests outside the component's rated tolerance.
Installation Tips
- Disconnect all electrical power to the HVAC unit before servicing.
- Discharge the existing capacitor to avoid electrical shock.
- Note the wire placement on the old capacitor's "C", "HERM", and "FAN" terminals before disconnecting.
- A 440V rated capacitor can safely replace a 370V capacitor, but a 370V cannot replace a 440V.
- Ensure the 50 MFD and 5 MFD ratings match the original part precisely.

it was a bit too hard/small for my Great Pyrenees, so it didn’t work out for my dog specifically
Color: 1PC-Beef-Red
is good quality and feels very durable and well made. The material is strong and holds up well against chewing, especially for aggressive chewers. It’s also a nice design and seems safe for dogs to use.

Indestructible dog toy
Color: 1PC-Beef-Red, Color: 1PC-Beef-Red
I have an 85 lb Pitbull and he loves to chew on those kind of hard bones but the meat flavor and scent is only in the middle the knobs on the end are just plain nylon and yes it is taking him a long time to get through them but little white fibers keep coming off I find them on the couch and he nibbles and tries to eat it so I believe he's eating the nylon and still has yet to get to where the beef flavor is in the center he doesn't chew from the middle he goes from the end all of his other chew toys he has he has demolished this one not so much I only gave four stars because my dog doesn't like it so much it is a very good sturdy toy though and has a good beefy smell. And a fair price.

Not completely indestructible but definitely long-lasting with plastic bits everywhere
Color: 1PC-Beef-Red
It's destructible it just takes a long time and tons of tiny little plastic pieces everywhere and even in your dog's stomach would not recommend due to wear and tear on dog's teeth and the plastic chips off.
