Review: PERFECT!!! - Worked perfectly! Shipped early the next morning after I ordered it. Packaged in padded box for protection. Customer support was clearly offered before opening package. I messaged the shipper through desertcart that I REALLY needed this board before the upcoming winter storm and he/she took it to UPS immediately to try to make that happen and I received it within 24 hours of our conversation. That was a lifesaver. Board was a perfect fit. Review: Great replacement part - This part was an exact fit and all of the wiring on the board was in the same spots. All of the stand offs were right too. Installed and powered up the unit and it went great. Price was on point and arrived when they said it would. ## Features - Low cost form, fit and functional replacement for Carrier: LH33WP003A - Direct Spark Ignition (DSI) control board - Microprocessor-based - Controls combustion, blower and indoor fan motors; spark ignitor; and the gas valve - Monitors timing, trial for ignition, flame sensing and lockout ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0046V6VF2 | | Best Sellers Rank | #718,195 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #666 in Furnace Replacement Circuit Boards | | Date First Available | October 11, 2010 | | Item Weight | 8 ounces | | Item model number | ICM291 | | Manufacturer | ICM | | Product Dimensions | 5 x 7 x 1.88 inches | ## Images ![ICM Controls ICM291 Furnace Control Replacement for Carrier LH33WP003A - Image 1](https://m.media-amazon.com/images/I/61LzUTp0tzL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ PERFECT!!! *by K***S on December 1, 2025* Worked perfectly!
