Samsung UH035CAV Limit Switch
The limit switch is a switch in the air handler that senses, or governs, when the air is actually warm enough to activate the main blower. Limit switches exist 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.
How can I tell if my critical limit switch is on its last leg?
- Your Samsung system refuses to start or will not stay running longer than 10 minutes
- The system starts to stop suddenly more often than not
