Samsung AVMDC052EA0 Limit Switch
A normal limit switch has a sensor in the air handler that can determine when the air is warm enough so that it may be pushed through the ducts and out the vents. One big reason why limit switches are designed that way is because if the air never warms up then the house will never get warm enough.
Warnings main limit switch will soon need to be replaced
- The Samsung system starts to go through the startup sequence but stops quickly on a regular basis
- The heating and AC system refuses to start nor will it stay running longer than a minute
