Could anyone help? I have a Lennox furnace and I cannot get the blower to shut off it stays on continuously. It is a new system put in back in July.

Thanks.

If the system was put in July it is still under warranty. Contact the company that did the install. Homeowners working on equipment still under warranty is a NO NO and can cause the warranty to be void.

Have you looked at the thermostat blower ON-Automatic switch. Many times the problem is there. Set to auto if in the on position.
