Payne PH3ZNA024000AA Limit Switch
Limit switches were created because if the air never warms up then the house will never get warm enough. A normal limit switch contains a sensor located in the furnace that makes the determination if and when the air is actually warm enough to activate the main blower.
Warnings of an ineffective main limit switch
- The HVAC system is unable to start nor will it stay running longer than a minute
- The whole system begins to behave differently often
