We have had close to 15 so far, not including the ones we have to go back and check, another dealer in the area has at least the same, serial numbers are from late in 2011 until week 41 of this year 2012, when they started installing the rubber washers, I heard ICP had sent out a statement to wholesalers
I went to a Carrier training class on heat pumps and the trainer acknowledged that they were having issues with this. He said it was caused by over tightening during assembly. He also said to contact the supply house and they will provide a replacement for free. Hope this helps.
Anyone else having a problem with cracked collector boxes from the factory in the new line of Bryant/Carrier or other icp furnaces?
Yes, in our class the instructor said some of the furnaces before the 29 th week of 2012 , had some problems with them cracking, some bad enough to cause pressure switch fault codes on the base model furnace, but not the 59mn7 modulating furnace.
The problem is on the new style furnaces with the serial numbers dated from late 2011 up until week 39-40 of 2012, my sales rep has down played the issue , we've had over 20 so far payne and bryant and know other dealers in my area have had the same issue... my bryant sales rep and a representative from my wholesaler said to my staff that they didn't want to put out a service bulletin because they didn't want to be overwhelmed by warranties.
