SPT WA-1150DE Limit Switch
A normal limit switch contains a sensor in the heating area that senses, or governs, when the heated air is warm enough for the air to begin normal home circulation. Limit switches are crucial because if the air never warms up then you will never get hot air through the ducts.
Signals main limit switch needs replacing
- The heating and cooling system will not begin nor will it stay running like it is supposed to
- The SPT system starts to initiate and then stops occasionally
