International Comfort Products NNE075F16G1 Limit Switch
Limit switches were created due to the fact that if the air inside the furnace is too cool 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 actually warm enough to activate the main blower.
Simple indications of a declining limit switch
- The HVAC system will not even start nor will it stay running for any length of time
- The system is beginning to run erratically time after time

If you are going to be buying or purchasing do your best and cross-check the model number and also make a visual inspection in order to be sure the correct replacement limit switch is the one being purchased. HVAC pros may charge higher prices than others so you may want to keep a lookout locally to find a good deal if money is of great importance to you.
