  • FYI (For Your Information):
    • A furnace limit is a safety device that is used to cut the gas burners off if the furnace over-heats.
    • If your furnace is going off on limit you might have an air flow problem like a dirty filter, dirty blower, slow blower motor (might need a new capacitor) stopped up evaportator coil or too much gas pressure.
    • All of these can cause the furnace to over-heat and go off on limit.
    • Many times when the furnace goes off on limit the fan blower will continuously blow because the furnace control board senses that the furnace has over-heated and needs to cool down.
    • The only way to get the blower to cut off is to turn off the furnace with the power switch.
    • You can test a limit with a volt meter to see if it is open or not.  On most limits you should get 24 volts from each of the two wires on the limit to a good ground.
