blower stays on

[saxman14701]

I have a Coleman 7900 series furnace. The furnace lights just fine and the blower comes on once it heats up, but when the heat goes off the blower shuts down and then restarts even though the heat hasn't come back on. My question is do I need it to replace the fan switch?

Maybe, either that or heat isn't dissapating fast enough and residual heat brings it back on.



Thanks for inquiring,
Robert
