when in auto it blows at about 50% when it is not suppose to be on when switched to on it blows harder.
I guess nothing is wrong with your furnace blower. This is how it works.
boy is cheifman long winded you have a low voltage short and or bad board enginers lol
Is it actually blowing or just making a sound like it is? The way a heater works, it warms the air first, then the blower blows the heated air through the vents. The sound you are hearing is most likely the warming process. It's not like A/C where you have instant cold, it takes a little time.
The Lennox G-sixteen furnace has a Fan administration heater it truly is energized the comparable time the main important gasoline valve opens. In 30 - 80 seconds the Fan administration contacts close and energize the fan in the process the Indoor Blower Relay's commonly closed contacts. in case you haven't any longer have been given this 30 2nd minimum postpone, replace the Fan administration that's the 1st area the pink blower twine connects to earlier it is going to the blower relay terminal #2. If somebody has bumped off the Fan administration from the circuit and jumpered the wires, you're turning out to be the comparable subject.
