Dometic 630516 Limit Switch
Limit switches exist due to the fact that if the air inside the furnace is too cool then you will never get hot air through the ducts. A normal limit switch contains a sensor in the heating area that determines if and when the air is warmed to a point that it can be circulated throughout the house.
Signs of a poorly working main limit switch
- The HVAC system refuses to kick in nor will it stay running like it ought to
- The whole system starts to run erratically on more than one occasion

If you are going to be buying or purchasing do your best and double check the correct model as well as make a visual inspection in order to be sure the proper replacement limit switch is the one being purchased. If you are unsure about the properly replacing the new limit switch by yourself then it may be wise to consult a pro to do the replacement of the part.
