Samsung EH052CAV Limit Switch
The limit switch contains a sensor in the air handler that senses, or governs, when the heated air is warm enough that it can be circulated throughout the house. Limit switches were created 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.
Hints limit type switch needs replacing
- The whole system begins to runs spotty on more than one occasion
- The heating and cooling system refuses to kick in nor will it stay running for any length of time
