Maintenance & Troubleshooting:
A 1-pole definite-purpose HVAC contactor used to switch higher-voltage loads from a 24V control signal in air conditioning, heating, refrigeration, and similar equipment.
Key Features:
- 24V coil/control voltage
- 40 amp rating
- 1 pole configuration
- Packard describes its contactors as "definite purpose" contactors designed for heating, AC, refrigeration, data processing, and food service equipment
Compatibility & Applications:
- Used as a 1-pole 24V control contactor in HVAC/refrigeration equipment where a 40A contactor is specified
- Must only be used where the manufacturer specifies this exact part number: C140A (verify against the equipment's parts list and ratings)
Installation & Operation Notes:
- Installation should be performed by a qualified HVAC technician or electrician
- Reference the serviced unit's wiring diagram/service manual to confirm:
- Correct pole configuration (1-pole vs 2-pole)
- Correct coil voltage (24V)
- Proper line/load wiring and secure terminations
- De-energize equipment before servicing and follow standard electrical safety procedures
Maintenance & Troubleshooting:
- Common replacement scenario (review-reported): outdoor A/C unit not operating due to an aging/failed contactor (including increased contact resistance from moisture/age)
- If the system still won't run after replacement, verify:
- Correct 24V call to the coil
- Tight, undamaged wire connections/terminals
- No shorts at the contactor or connected load

Thanks for the help
I know what I needed, I just couldn't find a local supply house that would sell to a non-contractor. The mice made a home of my A/C unit this winter and chewed some wires. All the accumulated moisture and age had increased the contact resistance of my contactor so I replaced it with this unit. Threw in a dual run capacitor and this 20+ year old A/C unit works like a charm again!

I wouldn't buy this product again.
You're service was great, The product wasn't. Lasted two weeks, I had to have a service tech. come out, he serviced the unit and could only find the contactor shorted out.

Dependable parts and service!
I service my ac units here at the house. When faced with a good old hot Texas, I must depend on good parts and good service! Supply House fits both - good parts and quick service!
Thanks Supply House!

Perfect replacement, shipped fast
Needed this for my failed AC unit. As it was a hot day I thought my local supply house would have the replacement but they didn't and they wanted a week to source it. WHAT?! My HVAC buddy told me about SupplyHouse.com... not only did you have the part but it was delivered next day! I've now been back a few times to order needed parts and I'm always 100% satisfied! Buy with confidence my friends!
