NewAir AC-12000H Limit Switch
One big reason why limit switches are designed that way is 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 has a sensor in the heating area that makes the determination when the heated air is actually warm enough for the air to begin normal home circulation.
Clues to watch for to know main limit switch should be replaced
- The whole system begins to behave differently repeatedly
- The heating and AC system refuses to start nor will it stay running even though max temp has not been reached
