Whirlpool ATR1252RPP0 Limit Switch
Limit switches are built because if the warmed air is too cool then the house will never get warm enough. The limit switch contains a sensor in the heat exchanger that can determine when the heated air is warm enough for the air to begin normal home circulation.
What are some indications that my chief limit switch is almost dead?
- System will not start nor will it stay running longer than 10 minutes
- The system begins to runs spotty more than once
