Payne PY1PNB018040 Limit Switch
Limit switches exist because if the warmed air is too cool then the house will never get warm enough. The limit switch has a sensor in the heating area that can determine when the air is actually warm enough for the blower to be activated.
What warnings are present when my limit type switch really is dying?
- The whole system is starting to runs spotty from time to time
- The heating and AC system is unable to start or run well longer that five minutes
