Whirlpool ATE0753SPP0 Limit Switch
The limit switch is a switch in the heat exchanger that decides when the heated air is warm enough so that it may be pushed through the ducts and out the vents. 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.
Important hints limit switch is failing
- The HVAC system is starting to ramp up but then stops from time to time
- The HVAC system refuses to start or run like it should
