Replaced the 32 year old (1991) circuit board on my 32 year old Carrier furnace as blower was turning off and on after every heating cycle is complete. Initially tried to find the original part number but is not available any more. So bought this replacement P/N ICM271 for original P/N CESO110018-00. The replacement was pretty easy. Replaced all the cables to the respective locations which were exactly the same as original board except HI and LO which are at slightly different location. But his was not an issue. Another issue was the jumper on GAS1 and GAS3 which is little wider on this board. So the old jumper could not fit and I had to buy a new jumper. After installation restarted the furnace and all works perfectly well. It seems blower noise is smoother than before. I am pretty satisfied with the purchase.
I have another furnace in the house with same P/N and have same problem. I am going to order another replacement board now.
I am very satisfied and hope it runs for couple of years now.
Received the product on time and in new condition. Easy to install and my system works fine now.
