Nordyne M2RL-060A Limit Switch
The limit switch has a sensor located in the furnace that decides if and when the air is warmed to a point for the blower to be activated. Limit switches are crucial due to the fact that if the air inside the furnace is too cool then the house will never get warm enough.
Major symptoms of a poorly working limit switch
- The system is starting to run inconsistently frequently
- The heating and AC system will not even start or run well as it should
