International Comfort Products PGME30G0904 Limit Switch
A normal limit switch is a type of sensor switch in the heating area that can determine when the air is actually warm enough for the air to begin normal home circulation. The reason limit switches exist is due to the fact that if the air inside the furnace is too cool the you will lose all the heat as the air flows through the ducts.
Symptoms of an inadequate limit type switch
- The HVAC system refuses to kick in nor will it stay running even though max temp has not been reached
- The International Comfort Products system starts to runs uneven frequently
