International Comfort Products HMH Limit Switch
The limit switch contains a sensor located in the furnace that can determine if and when the air is warmed to a point so that it may be pushed through the ducts and out the vents. Limit switches exist because if the air is too cool inside the furnace to begin with, then the house will never get warm enough.
Hints limit type switch needs replacing ASAP
- Your International Comfort Products system will not initiate nor will it stay running even though max temp has not been reached
- Your system is starting to shut down unexpectedly more often than not
