It is engineered to control the circulating fan in heat pump, air conditioning, and forced air systems. This control ensures optimal comfort levels by providing a one-second on-delay to allow air to reach proper temperature before energizing the fan, and a fixed sixty-second off-delay to purge ducts of residual air, thereby increasing energy efficiency.\u003c\/p\u003e\n\u003cp\u003eAs an authentic OEM equivalent component, the ICM255C ensures reliable performance with a low-cost, open board design and high-power relay output. It operates on a standard 24 VAC control voltage (18 to 30 VAC input range) and is compatible with a wide range of residential and commercial HVAC equipment models, serving as a direct wire-for-wire replacement for many OEM control boards.\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eKey Features and Function:\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDual Function Timer:\u003c\/strong\u003e Offers a 1-second on and 60-second off delay for heating and cooling cycles.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGenuine OEM Quality:\u003c\/strong\u003e Meets or exceeds original manufacturer specifications for reliable timing and performance.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnergy Efficiency:\u003c\/strong\u003e The 60-second off-delay clears ducts of residual conditioned air, increasing system efficiency.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWide Compatibility:\u003c\/strong\u003e Works with various HVAC models, including A-1, Bard, Mars, Rheem, and Snyder General\/ICP systems.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003e\u003cstrong\u003eProduct Details and Key Specifications:\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e ICM255C\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer:\u003c\/strong\u003e ICM Controls\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Type:\u003c\/strong\u003e Fan Blower Control \/ Fan Delay Timer\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eControl Voltage:\u003c\/strong\u003e 24 VAC (18-30 VAC input range)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShipping Weight:\u003c\/strong\u003e 4 LB\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFrequency:\u003c\/strong\u003e 50\/60 Hz\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTiming Range:\u003c\/strong\u003e 1-second ON delay; 60-second OFF delay (Fixed)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmperage Rating:\u003c\/strong\u003e 20 A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e 2.5 in L x 2.5 in W\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Open board design\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003e\u003cstrong\u003e🛠️ HVAC Depot Pro Tip: Diagnosing Noisy Airflow\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003eIf the \"On Delay\" function is faulty, the system may produce cold air at startup during heating mode. If the fan shuts off immediately after the compressor stops cooling, the \"Off Delay\" function is likely the issue, resulting in wasted conditioned air. Test the function by ensuring the fan engages after a 1-second delay during heating and runs for exactly 60 seconds after the thermostat satisfies the call for heat.\u003c\/p\u003e\n\u003ch2\u003e\n\u003cstrong\u003eCross-Reference:\u003c\/strong\u003e \u003c\/h2\u003e\n\u003cp\u003eThe ICM255C is a replacement for these OEM part numbers:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM \u0026amp; Catalog Numbers:\u003c\/strong\u003e ICM255C, ICM255, 8201-056 (Bard), 1395336 (Snyder General\/ICP).\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand Specific Replacements:\u003c\/strong\u003e Rheem 42-22515-01, 42-22515-02, 42-22515-03, 42-22515-04, Mars 32574.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e \u003c\/p\u003e","brand":"ICM","offers":[{"title":"Default Title","offer_id":52929152483691,"sku":"ICM255C","price":49.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0922\/9683\/9531\/files\/ICM255c.jpg?v=1771607722","url":"https:\/\/tophvacparts.com\/products\/icm255-rheem-fan-blower-control-oem-fixed-delay-timer","provider":"HVAC Parts and Equipment Depot Open To Homeowners and Contractors","version":"1.0","type":"link"}
