Whirlpool ATE0942RPP0 Limit Switch
Limit switches exist due to the fact that if the air never warms up inside the exchanger then the house will never get warm enough. The limit switch is a switch in the air handler that determines when the heated air is warm enough so that it may be pushed through the ducts and out the vents.
Major symptoms limit type switch should need replacing
- The system is starting to act weird time after time
- The HVAC system will not begin the ignition sequence or continue to run for any length of time
