SPT WA-1010M 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 contains a sensor in the heating area that can determine when the heated air is actually warm enough for the air to begin normal home circulation.
Important clues of a worsening limit type switch
- The heating and AC system refuses to start or will not stay running like it ought to
- The HVAC system starts to behave differently from time to time
