Mitsubishi PCA-A42KA Limit Switch
A normal limit switch contains a sensor located in the furnace that senses, or governs, when the heated air is actually warm enough that it can be circulated throughout the house. Limit switches exist because if the air is too cool inside the furnace to begin with, the you will lose all the heat as the air flows through the ducts.
Major warnings critical limit switch will soon need to be replaced
- The system is beginning to run inconsistently time after time
