      The blower motor in my forced air system is stuck on. I suspect the limit switch on the hot water line. Is the limit switch supposed to turn on or off the blower on heat rise? My switch turns off the blower on heat rise. The only other thing in the circuit is the air conditioner fan relay and removing this does not turn off the blower.

      Thanks,

      Bob

      This system is a forced air system that has its limit controls on the hot water line – figure that! I guess you have a hot water coil in the ductwork heating the air. Sometimes, people do control the heating fan by using a switch that starts the fan when the coil is warm enough. If the switch turns OFF the fan, then it is preventing the air from getting too hot – it is strange to control the system that way. So you need to find out more about your system.
