International Comfort Products PYMC Limit Switch
The limit switch is a switch located in the furnace that can determine when the heated air is warmed to a point for the main blower to kick in and circulate the air. Limit switches are crucial due to the fact that if the air inside the furnace is too cool the you will lose heat in the ducts and the vents will just blow cool air.
What are the clues to watch out for to know my chief limit switch really needs to be replaced?
- The HVAC system will not begin the ignition sequence nor will it stay running longer that five minutes
- The whole system is beginning to run inconsistently frequently
