Heat Controller B-VMH18FC-1 Limit Switch
The main reason limit switches are made is due to the fact that if the air never warms up inside the exchanger then the house will never get warm enough. A normal limit switch is a type of sensor switch in the heating area that determines when the air is warm enough that it can be circulated throughout the house.
Signs of a worsening main limit switch
- System is unable to start or will not stay running like it is supposed to
- The system is beginning to run inconsistently often

If you are going to be buying or purchasing, do your due diligence and double check the model number and also make a visual comparison so that you are positive that the correct limit switch is being ordered. If you are unsure about the correct way of installing the new limit switch by yourself then it is probably best to contact a professional to do the work for you.
