ICM P/N ICM271C – Genuine OEM Fan Blower Control (Dual On/Off Delay Timer, Direct OEM Replacement)

The ICM ICM271C (SKU: ICM271C) is a Genuine Original Equipment Manufacturer (OEM) dual-function fan delay timer designed as a direct replacement for thousands of specific OEM furnace control boards. It is engineered to control the circulating fan in heat pump, air conditioning, and forced air systems. This advanced control module provides precise fan management, ensuring optimal comfort by delaying the fan's start and end times to maximize energy efficiency and prevent the initial blast of unconditioned air.

As an authentic OEM equivalent component, the ICM271C ensures reliable performance with a low-cost, open board design and high-power relay output (10A N.O. 10A N.C.). It operates on a standard 24 VAC control voltage and is compatible with a wide range of residential and commercial HVAC equipment models, often serving as a universal yet specific wire-for-wire replacement for many proprietary boards.

Key Features and Function:

Dual Function Timer: Provides customizable ON and OFF delays for heating and cooling cycles.
Genuine OEM Quality: Meets or exceeds original manufacturer specifications for reliable timing and performance.
Integrated Potentiometers: Features adjustable ON/OFF delay times via onboard potentiometers for precise field calibration.
Universal Application: Direct replacement for thousands of universal 24V timing boards across various brands.

🛠️ HVAC Depot Pro Tip: Calibrating the Delay Timers

The main advantage of the ICM271C is its adjustable delays via the built-in potentiometers (the small adjustment knobs). A typical heating cycle requires an "ON" delay of around 30 seconds to allow the heat exchanger to warm up, while a "COOLING" off delay should be adjusted to clear the ducts of residual cool air without making the blower run excessively long. Ensure you consult your furnace or air handler manual for the exact recommended timing settings to optimize your system's efficiency and comfort level.

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.

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!!
