ICM Controls ICM856 PTCR Hard Start Kit – 130-156 MFD, 115-288 VAC, 1/2 to 10 HP

The ICM Controls ICM856 PTCR Hard Start Kit is a high-performance aftermarket motor starting device designed to improve compressor starting torque in residential and light commercial air conditioning and heat pump systems. Utilizing Positive Temperature Coefficient (PTC) technology, the ICM856 helps reduce compressor startup stress, minimizes voltage drop during startup, and extends compressor life by delivering additional starting torque when it is needed most. It is recommended for compressors ranging from 1/2 HP to 10 HP, with optimal performance in 2 to 5 HP applications.

The ICM856 features a 130-156 MFD start capacitor, operates on 115-288 VAC, and installs quickly with a simple two-wire connection. Designed as a cost-effective replacement for several popular hard start kits, it provides up to 500% increased starting torque, making it an excellent solution for aging compressors, low-voltage conditions, and systems experiencing hard starting.

Key Features and Function

Increases Starting Torque up to 500% – Helps compressors start quickly and efficiently under difficult conditions.
PTCR Technology – Positive Temperature Coefficient relay automatically removes the start capacitor from the circuit after startup.
Universal Two-Wire Installation – Fast and easy installation without additional relays.
Extends Compressor Life – Reduces startup stress and electrical strain.
Ideal for Hard Starting Compressors – Excellent for older systems and low-voltage applications.

🛠️ HVAC Depot Pro Tip: Hard Starting Compressor?

If your compressor struggles to start, especially during hot weather or under low-voltage conditions, installing a hard start kit like the ICM856 can significantly reduce startup amperage and improve compressor reliability. Always verify that the compressor itself is mechanically sound before installing a hard start kit.

Cross-Reference & Compatibility

The ICM856 directly replaces several popular PTCR hard start kits.

Happy Shouts From Our Thrilled Customers

William Bartlett

Cecil really saved me with troubleshooting tips over the phone. Thought I was going to have to replace the blower motor and ended up only needing a motor run capcitor. Thank you and God bless!

Verified Buyer

Riley Connolly

Cecil and Fidel were absolutely amazing and so helpful. We were happy they were open on Sunday, but was impressed with their knowledge and willingness to make sure we had everything we needed. If you need parts or service or install, I would recommend.

Verified Buyer

Cole Meger

Our AC went out during the hottest stretch of summer, and with a one-year-old at home, we were desperate for a quick fix. These guys came through big time — not only did they source the part faster than anyone else in the area, they also walked me through DIY troubleshooting while I waited. Trustworthy, knowledgeable, and run by a solid local family. As someone who owns rental properties nearby, I’ll be sourcing all my HVAC parts from them moving forward. Highly recommend!

Verified Buyer

Carl T. Droste

Had a power outage last night and during the 100 degree heat today noticed that the AC was not blowing any cold air. Pulled the capacitors to have them checked and also took video of the relay making noise even with the breaker was off. The proprietor and her staff were very friendly and helpful. She had the video analyzed and confirmed something was wrong. She checked one of the capacitors was a little low. Capacitor replacement is the biggest ticket item for HVAC repair. It is hundreds of dollars with the a capacitor only about $20.

Verified Buyer

Fuzzy Wuzzy

Cecil and his family have been a life saver. I walked in with very little knowledge on parts let alone how to repair my unit. All I had was my brother in FL who knows more than I do and Cecil at HVAC Depot. With 2 young kids at home I couldn't afford to wait for a HVAC tech. Cecil walked me through what I needed to know, even after hours when the shop closed. I successfully repaired the fan motor and replaced the capacitor. Thank you HVAC team for being totally awesome. Prices were amazing and I'm forever going to support this small family business. You and your family are what Texas is all about!!!

Verified Buyer

Linda Robinson

I called HVAC Depot and was absolutely blown away by the fast, courteous and exceptional service. They were very knowledgeable about explaining what they were doing and what had happened to the ac system. If you ever need a HVAC team they are best and they won’t hesitate by coming out and they won’t leave until you are happy with the service. Thank you so much for your excellent service. Kudos to you Michelle for your amazing customer service.

Paul Hamer

My AC went out in our home on Friday night. I went out and got the capacitor details and took them here first thing Saturday morning. Lady at the counter was friendly and had the capacitor I needed! When I got home, I installed the capacitor and AC is all good!!
