Whirlpool ATE1553SPP0 Limit Switch
A normal limit switch is a switch in the heat exchanger that determines when the heated air is warm enough to activate the main blower. One big reason why limit switches are designed that way is because if the air never warms up then you will never get hot air through the ducts.
Warnings limit type switch should need replacing
- The whole system begins to become unpredictable occasionally
- The heating and AC system will not even start or continue to run even though the desired temperature has not been attained
