carrrier blower wont shut off
 
I have an old Carrier furnace model 58gp125-2. The blower motor wont shut off. I've checked the thermostat wires on both ends no loose or touching wires. The thermostat is turned off fan set on auto. Ive tried turning off all the power to the unit and turned it back on, no luck. I also looked for a reset button, none visible. Any suggestons.

Air filter probably is/was dirty and restricted air flow too much. And the limit switch is now stuck open.

Changed filter, still running. Should limit switch automatically reset?

Normally it would.

But, after so many times it won't. And it needs to be replaced.

how bad was your air filter?

Not bad was changed back in late july.
