International Comfort Products T8MPL050B12B1 Limit Switch
The main reason limit switches are made is because if the warmed air is too cool then the house will never get warm enough. The limit switch has a sensor in the heat exchanger that determines if and when the air is warmed to a point so that it may be pushed through the ducts and out the vents.
Hints limit switch should need replacing
- The whole system is starting to behave erratically repeatedly
- The heating and cooling system is unable to start nor will it stay running longer than 30 seconds
