Whirlpool ATR0942RPP0 Limit Switch
The main reason limit switches are made is due to the fact that if the air never warms up inside the exchanger the you will lose heat in the ducts and the vents will just blow cool air. The limit switch contains a sensor in the heating area that determines when the air is actually warm enough for the main blower to kick in and circulate the air.
What to see if the limit switch most likely really needs to be replaced?
- The HVAC system begins to erratically more often than not
- Your Whirlpool system refuses to kick in nor will it stay running longer than 10 minutes

Before you decide on buying or ordering do your best and make sure of the correct model as well as make a visual inspection in order to be sure the right limit switch is being ordered. There is no rule that says you have to install the replacement part alone. Hire someone with experience in your community to do it for you.
