Nordyne M1BB086 Limit Switch
One big reason why limit switches are designed that way is because if the warmed air is too cool then the house will never get warm enough. A normal limit switch is a switch located in the furnace that senses, or governs, when the heated air is warmed to a point that it can be circulated throughout the house.
Simple indications poorly running limit type switch
- The Nordyne system begins to stop suddenly more often than not
- The heating and AC system will not begin the ignition sequence nor will it stay running like it should
