I have been having a few problems with my blower.Sometimes it will kick on for a second or two and then shut off.It does this even when there is no call for heat.It is intermitent.
Now it has a bigger problem.The furnace will call for heat burner comes on,then when the fan should come on it doesn't.Then the upper resetable limit kicks out.I shut it down and let it cool off reset the limit.When this happens the fan is real hotter and actually seems froze up.I have to let it cool some before I can turn the cage.
I have also lost the ability to turn the fan switch from auto to ON and have the fan run.It only works in the auto setting.I will have to get a meter out and do some tracing.
I am afraid I might be having a fan motor on its way out.Looking for anyother reasons for what might be causing these problems so I can repair them.
