Whirlpool ATR0753BPP0 Limit Switch
Limit switches were created because if the air never warms up then the house will never get warm enough. The limit switch contains a sensor located in the furnace that determines when the heated air is actually warm enough for the air to begin normal home circulation.
How do you know when your chief limit switch is dying?
- System will not begin nor will it stay running even though the desired temperature has not been attained
- The whole system begins to behave differently more than once
