Description
- SWT01280 American Standard Trane Furnace Limit Switch is a brand new OEM factory limit switch that comes in a Service First Factory OEM box.
- The SWT01280 Limit Switch is used on many Trane and American Standard furnaces. Please see the list of furnace models where this limit is used below.
- The specifications on the furnace limit switch are: THERMAL LIMIT, OPEN @ 155 F, CLOSE @ 125 DEG F. This means that this limit switch opens and cuts off the gas burners when the temperature inside the furnace heat ex-changer reaches 155 F and closes back to allow the burners to come back on when the heat ex-changer reaches a temperature of 125 Degrees F.
- 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.
