International Comfort Products PA5536AKA1 Limit Switch
One big reason why limit switches are designed that way is because if the warmed air is too cool then the house will never get warm enough. A normal limit switch contains a sensor in the heating area that senses, or governs, when the air is actually warm enough for the blower to be activated.
What are some hints that my limit type switch really has a need to be replaced?
- The International Comfort Products system is starting to behave erratically on a regular basis
- The heating and cooling system refuses to start or will not stay running even though max temp has not been reached
