Carrier FF1DNE018075AAAA Limit Switch
A normal limit switch is a type of sensor switch in the heating area that determines when the heated air is actually warm enough for the blower to be activated. A limit switch was crafted due to the fact that if the air inside the furnace is too cool then you will never get hot air through the ducts.
What warnings are present when my main limit switch has a need to be replaced?
- The HVAC system refuses to kick in nor will it stay running even though the desired temperature has not been attained
- The Carrier system is beginning to run inconsistently repeatedly
