Sanyo XS1872 Limit Switch
Limit switches were created because if the air never warms up then the house will never get warm enough. A normal limit switch has a sensor located in the furnace that decides when the heated air is actually warm enough that it can be circulated throughout the house.
Indications main limit switch should be replaced
- The whole system starts to runs spotty repeatedly
- The heating and cooling system will not begin or run well longer than 30 seconds
