Carrier HH660103 Rollout Switch Kit

The Carrier HH660103 is a Rollout Switch Kit that is an essential part of HVAC equipment. A last line of defense against overheating safety devices. Despite its size, this kit, which includes several components, measures 6.1" high, 2.9" wide, and 2.7" long, but it's essential in preventing potential system damage. In case of excessive heat build up in your Carrier unit, this switch automatically interrupts gas supply to the burner. This can happen because of a blocked flue, bad blower fan, or any other problem. The rollout switch cuts off gas supply, protecting your system from overheating, fire hazards and expensive damage.
