UPM Marketing Inc. has announced a voluntary recall and product upgrade replacement of its Line Voltage Thermostats.

The potential hazard is that the unit may overheat and emit smoke, especially when the load has exceeded the specified maximum rating. When the warning was issued on December 14, 10 cases of minor smoke/soot damage to the wall surface were reported. No injuries were reported. 

The affected model numbers are: HTM611A and HTM621, Noma models: HTM611A (52-2544-0) and HTM621 (52-2545-8). Affected units were manufactured in 2008 and have a serial number starting with “08”. Units with serial number not starting with “08” are not affected.

These devices were manufactured by W.H. Mandolyn International Ltd. in Hong Kong, and approximately 1,000 have been sold in Ontario and 9,000 sold in the rest of Canada.

Most of the affected units were distributed in 2008 and early 2009, and were sold by Canadian Tire.
