2-5 Ton Champion Gas heat – Electric Cool Units With ECM (Variable Speed) Motors periodically failing to run on a call for cool

Type: Service Alert
Equipment: Air ConditionerHeat Pump
Recall or Alert Date: 09-22-2006
Serial Number: YS-049-06
Brands Affected: York

Description of Problem:

We have received reports of customer complaints that these units could freeze up from time to time. Investigation found that the ECM blower motor used would sometimes not respond to a thermostat requiring call for blower operation. When this happens, the compressor could operate without the blower motor, causing the coil to freeze. The problem reportedly happened at different rates on different applications. Some regularly, some only periodically.

From reports received from the field, the issue seems to be isolated to the Gas/Electric units. No confirmed Heat Pump or Electric/Electric units have been reported. The Gas / Electric units use a Honeywell control center to operate the unit.

Affected Products:
