International Comfort Products C8MPL050B12B1 Limit Switch
Limit switches are built because if the air is not warm enough then the house will never get warm enough. The limit switch is a switch in the heat exchanger that makes the determination if and when the air is warm enough for the main blower to kick in and circulate the air.
Key signs of a barely functioning limit switch
- The heating and AC system is unable to start or will not stay running longer than 30 seconds
- The whole system is starting to initiate and then stops more often than not
