SINGLE STAGE INTEGRATED FURNACE CONTROLS (IFC) SOLDER TERMINAL FAILURES

Type: Service Alert
Equipment: Furnace
Recall or Alert Date: 10-11-2001
Serial Number: 3-01
Brands Affected: Trane

Description of Problem:

Since the beginning the 2nd quarter of 1999, field complaints reported failures of the “K1” relay powering the circulating blower on the furnace controls CNT02789 (particularly in downflow models). More recently, similar reports have been received on other single stage furnace models (see list above). The failure appears as burned solder joints of the relay pins on the backside of the PC board
